FAQ

How does Internet-in-a-Box (IIAB) help?

Do you need the best of the Internet (Wikipedia, OpenStreetMap, Khan Academy, Stack Exchange, ETC) with local content and learning apps for all?

Customize an "Offline Internet" for your school, for your community — or for your very own family!

Listen to the 23min BBC podcast "How to put the internet in a box" (2020-10-20) to learn how this works. See also a great community example in North India (3min) from 2021. Internet-in-a-Box (IIAB) is used in medical clinics as well, as can be seen in this Dominican Republic video.

Please see our internet-in-a-box.org web site.

Internet-in-a-Box brings the power of a free Digital Library of Alexandria to any community worldwide.

Whether costing $10 or $1000, an Internet-in-a-Box "learning hotspot" brings classroom/library devices to life, in ways that very deeply empower learning and community.

RECAP: To create your own Internet-in-a-Box [1] [2], look over a few live demo examples and check out our growing collection of videos.

Internet-in-a-Box arose from One Laptop Per Child's original school server (2007-2012) and our global grassroots community, adding in the quality content and learning apps shared by the best educational systems worldwide.

Now anyone can do this, building up your local community's very own 21st Century digital library, using free and open source software.

READY, SET, INSTALL: Internet-in-a-Box (IIAB) is built by a global network of professional volunteers, inspired by One Laptop Per Child's famous laptops and their innovative Sugar Learning Platform — but now with a much wider vision of serving all — both in schools and beyond.

Where is Internet-in-a-Box used?

Internet-in-a-Box (IIAB) is in use in dozens of countries, from smaller communities to large-scale institutional deployments.

Please see our regular global community updates at: @internet_in_box

Examples include orphanages and schools in Haiti, schools across southern Mexico, rural communities and libraries across southwest Ghana, remote schools in Myanmar/Burma and Cambodia, villages across India, a girls science school in Rwanda, community centers in Kenya, a youth community in rural Malaysia, to South Africa townships — as well as broad Central American deployments like Nicaragua, Costa Rica, and the Dominican Republic.

Libraries and rural medical clinics are also avid users of IIAB, in places like Guatemala, the Dominican Republic.

Many contributors are also using IIAB for more personal/grassroots and home library purposes too, helping refine our community product for increasingly diverse and larger impacts.

What can I do with E-books and Internet-in-a-Box?

Unleash the best of Internet learning without costs or distractions. Pack your Internet-in-a-Box (IIAB) full of incredible Wikipedia + Maps + Literature + Khan Academy + Video!

The first step is to add content gems to your IIAB. Learn how to download high-quality free content, like Wikipedia ZIM files.

Not just schools but also medical clinics, museums, and prisons are taking advantage — as well as individual educators and parents taking charge by building their very own "Library of Alexandria" community learning hotspots.

How can kids best take advantage of these crown jewels of learning? After you've added content, offer your students direct access via IIAB Apps like:

 http://box            Your Internet-in-a-Box Library!
 http://box/usb        Content from USB sticks/drives, that teachers can insert anytime

Can teachers display their own content?

Yes, teachers can spontaneously insert (and remove!) their own USB memory sticks and USB drives anytime. Somewhat like an informal projector, the teacher's content appears for students almost instantly at:

 http://box/usb

Instructions:

1. We recommend teachers use USB memory sticks/drives formatted with the FAT32 filesystem. Linux filesystems like ext4 can also work. Automount support for newer/larger exFAT-formatted sticks and NTFS-formatted portable disks was added in February 2018.
2. Teachers insert their USB sticks/drives into any of the Internet-in-a-Box's USB ports, Done!
3. This Teacher Content is available (live) to students within seconds. WARNING: Some browsers and non-standard phones/devices cannot access http://box/usb, and so require that students type in http://box.lan/usb or http://10.10.10.10/usb

Warnings:

1. If you're using the Desktop (graphical) version of Raspberry Pi OS, please consider this workaround so that USB drives mount cleanly every after boot: #2456
2. While generally not necessary (or realistic, for rural teachers etc, as mentioned on #2277) you can unmount drives by running: systemctl stop usbmount@dev-sda*
3. USB memory sticks/drives may need to be removed and re-inserted into your Internet-in-a-Box before Teacher Content appears e.g. if stick was inserted just prior to a cold boot: #329
4. Traditionally, the teacher needed to create a folder called "usb" on their USB memory stick, placing audio/video materials, handouts, challenges or presentation(s) inside that folder. However this "usb" folder is No Longer Required as of May 2018 / IIAB 6.5 (by default!) If however you prefer the old approach, please set iiab_usb_lib_show_all: False in /etc/iiab/local_vars.yml prior to installing IIAB.
5. Note that all Linux users should be able to read and write to USB drives inserted into IIAB as of 2021-03-25 (PR #2715). Kolibri requires this. If however you prefer to block non-root users, please set usb_lib_umask0000_for_kolibri: False in /etc/iiab/local_vars.yml prior to installing IIAB.

CLARIFICATION: it's OK to insert multiple USB sticks/drives at the same time. If so, content from each USB stick/drive is visible within http://box/usb, e.g. in sub-folders that will be obvious, like the following:

 http://box/USB0
 http://box/USB1

Or possibly:

 http://box/usb/USB0
 http://box/usb/USB1

See the Install Doc for background details.

CLARIFICATION: If your Linux OS has a graphical desktop, it's common to see popup message warnings like:

 Unable to mount 128 GB Volume
 Device /dev/sdb1 is already mounted at '/media/usb0'.

It's safe to ignore these messages. Or you can make these popup messages go away, typically by clicking through your graphical File Manager's preferences or OS settings, and unchecking the box for "Mount removable media automatically when they are inserted" or "Automatically mount removable media when inserted and on startup." #86

You can order a 256GB model from the Wikipedia Store — or order a language-customized version of Internet-in-a-Box from the Wiki Project Med Foundation who will ship from Canada to almost any location worldwide — if you help provide feedback to improve the product for all.

A South Asia edition was also available in India. But it is unclear if they are still willing to ship.

What hardware should I use?

Internet-in-a-Box (IIAB) is free and open source software that runs on many GNU/Linux platforms:

• The Raspberry Pi 4 ($35+), Raspberry Pi 5 ($50+) and Raspberry Pi 400 ($70 computer-in-keyboard) are best for classrooms, in almost all cases! Their internal Wi-Fi hotspot supports up to 32 student WiFi client devices (but see #823 for the very latest Wi-Fi firmware info!) RECOMMENDATION: Buy any Raspberry Pi with at least 2 GB RAM, especially if your Internet-in-a-Box will include Kolibri, Moodle or Nextcloud.
  • The older Raspberry Pi 3 and 3 B+ ($35+) are also possible, despite their 1GB RAM limitation.
  • Finally the Raspberry Pi Zero W ($10) and Raspberry Pi Zero 2 W ($15) work great as learning kiosks, despite their meager 512MB RAM (Internet-in-a-Box is used in rural medical clinics, and by families in their homes). NOTE that your microSD card should be prepared with IIAB software and provisioned with Content in a more powerful Raspberry Pi — then later insert the microSD into your Zero (2) W. (It continues to astonish us how powerful these tiny computers really are, the size of a cigarette lighter yet able to serve 32 students simultaneously, with their powerful built-in Wi-Fi!)

• Refurbished "PC" Laptops & Thin Clients: When recycled / upcycled conscientiously, quality donated laptops and PC's can work extremely well as your Internet-in-a-Box, becoming a "Learning Hotspot" or server for an entire developing world classroom or small school. If the laptop's internal Wi-Fi works as an access point, this allows for a hassle-free self-contained unit, as is greatly preferred by most developing world schools (to control operational costs, spaghetti wiring, theft of router, etc). Conversely if the laptop's internal Wi-Fi cannot be used as an access point, an external Wi-Fi router can be made to work if truly necessary. In any case, make sure the laptop has a reasonably new battery, acting as a de facto UPS (critically important in developing world schools where electricity comes and goes). Naturally: laptops with large hard disks and multiple GB of memory are preferred — definitely check that the laptop runs 64-bit Linux well, preferably with a BIOS that permits it to run while the screen is closed.

• Mini PC's like the ASUS NUC (acquired from Intel in 2023): Avoid classic/desktop PCs whenever possible, as they consume far too much electricity. However: tough, well-rounded, low-power Mini PCs (such as the NUC) world extremely well, and have proven very effective as school servers in the developing world since 2014. We prefer Mini PC's models that accept 2.5-inch SATA drives (HDD or SSD) and work with DC voltages up to 19V. WARNINGS:
  • The internal Wi-Fi in most NUC computers is regrettably blocked from connecting to more than 12 Wi-Fi client devices. Compare this to the Raspberry Pi's mentioned above — whose internal Wi-Fi can support 32 simultaneous Wi-Fi client devices!
  • Low-end NUC models only work right near 12V, and so are not reliable using lead-acid batteries that you find in most solar installations. Read the spec carefully, for the exact model you're considering!
  • Finally: the NUC is not a fan-less device, but nevertheless has proved very reliable across diverse climates.

• Other Mini PC competitors: MSI units have proven very solid, and Zotac perhaps less so. Consider also Beelink's NUC clones, and Gigabyte BRIX (e.g. GB-BSI3H-6100) which likewise is almost an exact clone of the NUC. The BRIX allows internal Wi-Fi to scale beyond the NUC's annoying limitation of 12 connections maximum, if you insert an appropriate Atheros Wi-Fi module (typically < $10) into the BRIX. George Hunt can answer questions around which Atheros Wi-Fi modules have been tested to work, as of February 2017. Recap: scaling up internal Wi-Fi is sadly not possible with NUCs since 2015 (5th generation NUCs and onwards) as the NUC's Wi-Fi module is unfortunately soldered in.

• ARM Mini PCs: CPUs like TrimSlice / Utilite CompuLab and Cubox by SolidRun might one day catch up, providing much-needed community momentum and packaging. To date however we have been disappointed with their firmware, and the lack of availability of Linux kernels/drivers working with internal SATA / internal Wi-Fi (e.g. AP mode), to truly make teachers' lives easier. But check back as many more global deployments' experiences accumulate, and rugged low-end hardware increasingly emerges, on OrangePi or similar?

MEMORY: Some do fine with 512MB RAM (even in 2024!) serving static content from the RPi Zero W. Others do just fine serving dozens of simultaneous video streams from an RPi3 (or 3 B+) with 1GB RAM. Finally, certain others require 2GB or 4GB from an RPi 4 — or 8GB or more within a Mini PC — when server-side loads become very intensive. For example if you are running an LMS, experiencing a lot of OpenStreetMap traffic, running a Wikipedia Treasure Hunt with multiple students running full-text searches of Wikipedia — or offering streaming & fileserver-like capabilities broadly to many students.

STORAGE: While there's increasing movement from hard disks to SSDs and microSD cards every year, many others still swear by tried-and-true hard drives. Certainly rotating media are the clear winner when TB (or multi-terabyte) storage is needed at a low price. In the end all storage technologies can fail, each in there own ways. So it's far more more important to start with the actual community's learning goals, engaging educators around their authentic content/interaction needs — and then narrow in on storage capacity/technologies later. Alternative: consider this earlier discussion of external USB hard disks and their possible risks.

HEAT/DIRT/DUST: Ensure your server is positioned with ample room around it for ventilation, away from direct sunlight. Dirt/dust will collect inside it almost regardless, and should certainly be removed from time to time.

What OS should I use?

Check IIAB Platforms for the latest Linux OS compatibility details!

1) Raspberry Pi OS on Raspberry Pi 4, 5 or 400 is best if this is your first time — regardless if you prefer the full/graphical Raspberry Pi OS with desktop with its great desktop apps for students — or consider Raspberry Pi OS Lite for a more lightweight "headless" server:

• Either way we recommend 64-bit Raspberry Pi OS (Bookworm) (originally released 2023-10-11, #3657) which is about "48% faster" (prior to 2022 we recommended 32-bit Raspberry Pi OS, but the 64-bit version has since matured).
  • The NOOBS OS is NOT supported.
  • Ubuntu 24.04.1 LTS and Edubuntu can also work, but use substantially more memory.

2) On PC-like hardware (or virtual machines) pick a 64-bit OS from this list: (either with graphical desktop or "headless", and whether-or-not with LTS multi-year support)

• Linux Mint 22 and Edubuntu are easy to install, with a friendly graphical desktop (security updates until April 2029).

• Ubuntu 24.04.1 LTS (security updates until June 2029)
  • Ubuntu 24.10 pre-releases work well too (final release 2024-10-10, with end-of-life July 2025) if you don't mind its very short life span.

• Debian 12 (Bookworm) was released 2023-06-10 (security updates until roughly July, 2026 to June, 2028). CAUTION: Debian Edu (Skolelinux) is not supported.
  • Debian 13 (Trixie) pre-releases might work (at your own risk!) CAUTION: Debian Edu (Skolelinux) is not supported.

Others like Reno McKenzie & Josh Dennis experimented successfully (tweaks required!) with IIAB on the lean & mean DietPi.com back in 2017. Similarly, Ubermix 4.1 was successfully tested in 2019.

Please avoid Docker, as our Ansible provisioning requires low-level access to the operating system.

Finally, if there are situations where porting to a new OS/distribution will tangibly help schools/libraries/clinics across an entire region, please don't hesitate to reach out as you assess the scope-of-work to complete such a job.

Is a quick installation possible?

1. Yes! Download one of our IIAB Images for Raspberry Pi to your microSD card. You can then boot the microSD card in almost any Raspberry Pi.

Clarification: the above IIAB images contain software only (you then add content !) and can occasionally be months out-of-date.

2. If you want the very latest IIAB software that undergoes continuous improvement and QA, we recommend you instead use the 1-line-installer at download.iiab.io and check out IIAB's new Technical Contributors Guide.

First verify that your hardware and Linux OS are appropriate:

• If you're using a Raspberry Pi 4 or 400 (or the older 3 or 3 B+) install the latest 64-bit Raspberry Pi OS (do NOT use NOOBS!)

• If you're using a PC/Laptop or VM, install a minimal OS like Ubuntu 22.04+, Debian 12+ or Linux Mint 21+.

Then run IIAB's 1-line installer to install Internet-in-a-Box (IIAB) 8.0's latest pre-release, by typing in:

  curl iiab.io/install.txt | bash

This can take an hour or more to complete — depending whether you choose SMALL-sized (~11 server apps), MEDIUM-sized (~15 server apps) or LARGE-sized (~29 server apps) as the installer begins. Use our comparison table below, to decide which is most suitable for your needs.

An Ethernet cable (connected to fast, live Internet) is strongly recommended during installation, as well as a modern microSD card (with fast write speeds), and a well-ventilated Raspberry Pi!

While a lot has changed since 2019, consider also the "ZERO to IIAB" installation video on our YouTube channel.

Remember: IIAB's 1-line installer might need you to run sudo iiab multiple times, before IIAB's software install fully completes — e.g. if Internet connectivity is interrupted for any reason. When your IIAB software install is 100% complete, you'll be asked to reboot — typically within about-an-hour-or-so (so you can begin installing content!)

3. Linux hackers: other distros might be possible, but can require extensive babysitting to get right. Consider the long-form "Do Everything from Scratch" install instructions if porting IIAB to a new Linux distribution is your goal.

What services (IIAB apps) are suggested during installation?

When installing Internet-in-a-Box (IIAB) at https://download.iiab.io, you're given a choice of SMALL-sized, MEDIUM-sized or LARGE-sized — to get you started fast!

Which services (IIAB apps) are included in each of these 3? The summary table below helps you choose among IIAB's almost 40 powerful apps — optionally with a complete LMS (learning management system) like Kolibri, Moodle, WordPress, Sugarizer or Nextcloud.

Then, after choosing among these 3 sizes, IIAB's installer encourages you to further refine your choice of IIAB apps — by customizing your very own /etc/iiab/local_vars.yml

More generally, see our Tech Skills Videos (alternate view) focused on networking, Raspberry Pi, web basics, and security — with subtitles in English, Spanish and French. Some of which are also on IIAB's YouTube channel.

Offline Field Operators should also check our growing collection of Internet-in-a-Box tech support docs (and eventually videos!) available on your very own Internet-in-a-Box at http://box/info

Finally you can force your IIAB to update these offline docs (when your IIAB is online) by running: /usr/bin/iiab-refresh-wiki-docs

What is Ansible and what version should I use?

Ansible is software that orchestrates the installation of Internet-in-a-Box (IIAB) and its apps/services.

FYI the latest Ansible version recommendation is posted near Line 11 of scripts/ansible.

If you must upgrade Ansible, make sure your IIAB is online, and then run:

 cd /opt/iiab/iiab
 sudo scripts/ansible

Done! (It will explain how to verify your Ansible installation.)

Finally if your IIAB is much older, upgrading Ansible can be challenging (And At Your Own Risk). But if you must: (run as root, when your IIAB is online)

1. Run ansible --version to see what version of Ansible is installed.
2. Remove all prior versions of Ansible using apt purge ansible-core (or apt purge ansible-base or apt purge ansible or pip3 uninstall ansible-core or pip3 uninstall ansible-base or pip3 uninstall ansible) depending on how Ansible was originally installed — if necessary see #564
3. Remove any and all lines containing "ansible" from /etc/apt/sources.list and the files in /etc/apt/sources.list.d/
4. Once again try to run cd /opt/iiab/iiab then sudo scripts/ansible
5. Run ansible --version and/or pip3 show ansible-core to verify (on rare occasion you might first need to log out and log back in, if Ansible ends up being moved, e.g. from /usr/bin to /usr/local/bin or vice versa)

CLARIF: None of the above should be required if you're doing a fresh install on a clean OS, using IIAB's 1-line installer from: https://download.iiab.io (which installs Ansible for you!)

PRO TIP: IIAB's Ansible install script attempts to upgrade ~4 Ansible Collections as well. See the line that begins with: ansible-galaxy collection install --force-with-deps

PRO TIP: For those wanting to run a single Ansible playbook or role, run cd /opt/iiab/iiab then sudo ./runrole <ROLE NAME> (see runrole's source code).

My Android device says "Connected, no Internet" and won't browse http://box

1. The message "Connected, no Internet" is perfectly normal (in an offline environment). Just beware Android may block you from using Wi-Fi to access Internet-in-a-Box content (preventing your browser from displaying http://box) unless you follow these instructions:
   1. Connect your Android device to the correct Wi-Fi for Internet-in-a-Box.
   2. Recent versions of Android will generally beep within about 1 minute, announcing "Wi-Fi has no Internet access" and "Tap for options".
   3. Tap for more options (you may need to use your finger to find this notification first, pulling it down from the top of your Android screen).
   4. When it asks "This network has no Internet access. Stay connected?" be sure to tap "Yes" !
   5. If you were unable to tap in time, and http://box is still not working in your browser, try to "Forget network" (within Android's Settings -> Wi-Fi networks) then start over, proceeding from Step 1. above.
2. Recent Samsung and Huawei smartphones (since about 2019) require to you to Turn Off "Mobile Data" before you can browse to http://box, http://box.lan or http://10.10.10.10 (or http://172.18.96.1 if your Internet-in-a-Box pre-dates July 2022)

What are the default passwords?

For KA Lite, Kolibri, Calibre, Calibre-Web, Nextcloud, Moodle, CUPS, Elgg, JupyterHub, Transmission, etc the administrative user is Admin (don't forget the capital A) and the default/initial password is: changeme — WordPress as well, often uses this same account. For MediaWiki however, Admin/changeme2020 is the initial username/password.

An example is Calibre-Web's "teacher" account (Admin/changeme) which can add/remove and convert E-Books, and also change their metadata, at http://box/books. Whereas Calibre itself (if installed, typically at http://box:8080) uses these 7 "student" accounts, to read or download E-Books: box/box, h/h, ht/ht, m/m, mx/mx, p/p or pe/pe (as of Internet-in-a-Box 7.0). If you have access to the Linux command-line, you can change Calibre's accounts by running: calibre-server --manage-users --userdb /library/calibre/users.sqlite

However for IIAB's own Admin Console[*] at http://box/admin, http://box.lan/admin or http://10.10.10.10/admin, the username is iiab-admin and the default/initial password is: g0adm1n (note the numbers 0, 1). GNU/Linux administrators can also use this to login over ssh.

Change iiab-admin's password before connecting your server to the Internet. You can do this within http://box.lan/admin -> Utilities menu — or at the command line, if you run: passwd iiab-admin

[*] While the Admin Console can change iiab-admin's password instantly, it's important to understand that many Admin Console changes (within its Configure menu especially) require you click "Save Configuration" then "Install Configured Options" and then wait for this to complete. Monitor for Status "SUCCEEDED" under Utilities menu -> Display Job Status (takes about 20 min on a Raspberry Pi 3, 3 B+ or 4, depending what changes you've requested!)

Finally, certain install-time passwords are listed in /etc/iiab/local_vars.yml — which overrides passwords listed in default_vars.yml. If you modify any of these passwords in local_vars.yml after installing IIAB, don't forget to then run Ansible, e.g. using "Install Configured Options" above! 2020-09-23 Warning: MySQL/MariaDB passwords cannot easily be changed after IIAB install (#2542).

Admin Console: Note that very occasionally it might be necessary to run systemctl restart iiab-cmdsrv.service if http://box.lan/admin shows red errors upon login.

Warning: KA Lite's Admin password cannot be changed in a browser (http://box:8008 can only change KA Lite's user passwords) so you need to run kalite manage changepassword Admin — help is available if you run: kalite manage help changepassword

Where can I see live demos of Internet-in-a-Box?

Please see these live demo examples as used by medical clinics in 2018, hosted by the Wikimedia Foundation (Wikipedia).

Many more examples from schools in Jamaica, Mexico, Haiti and other places around the world, will be posted. Here is a South Asia Medical Version including more than 30 languages. Please contact us if you:

1. Want to see diverse snapshots firsthand, to inform your own Internet-in-a-Box design?
2. Have community examples that should be showcased right here, to assist others?

How do I customize my Internet-in-a-Box home page?

OPTIONAL: Some 2019 videos on Internet-in-a-Box's YouTube channel (several available as .mp4 and .webm) are a bit out-of-date, but can illustrate the big picture, showing how to get moving downloading and arranging content on your Internet-in-a-Box (IIAB).

Your IIAB home page is usually reachable at http://box, http://box.lan or http://10.10.10.10 from any nearby smartphone, tablet or laptop/computer. If you've just installed Internet-in-a-Box (IIAB) on your home network, here are some great tricks to find its IP Address.

You can build a beautiful IIAB home page for your community by following these steps:

1. Add content to your IIAB, by downloading the Content Packs you need using the Admin Console (http://box/admin or http://box.lan/admin) with default password above:
   1. Click the Install Content tab, then explore Get ZIM Files from Kiwix and Get OER2Go(RACHEL) Modules on the left.
   2. If instead you want to load content from a USB drive, click Manage Content on the left.
   3. Multi-gigabyte Content Packs can take hours to download, unpack & install! Consider limiting yourself to 10-or-fewer Content Packs at a time, to avoid thrashing! Monitor the progress under Utilities tab -> Display Job Status — until all are marked as "SUCCEEDED" in the Status column.
2. Rearrange / re-order your menu items (the Content Packs and IIAB Apps on your IIAB home page) including those that were added just above:
   1. Easy Way - use the drag-and-drop interface within Admin Console (http://box.lan/admin) -> Content Menus tab -> Edit Content Menus -> Content Item List. You may need the "Load Menu", "Save Menu" and "Select Languages" buttons.
   2. Or Manually - rearrange the order of menu items by editing the menu_items_1 array in /library/www/html/home/menu.json.
3. If you need to change the description or logo for any particular menu item:
   1. Change its description by editing the menu item's .json and/or .html files within /library/www/html/js-menu/menu-files/menu-defs (e.g. to change the description of Practical Action, edit en-practical_action.json and/or en-practical_action.html).
   2. Change its logo by placing a new logo file in /library/www/html/js-menu/menu-files/images, making sure that logo_url is set to the correct logo filename (in its above-mentioned .json file).
4. Finally, to showcase your school logo or community colors broadly on your Internet-in-a-Box home page, you can customize /library/www/html/home/index.html and the CSS files in /library/www/html/js-menu/menu-files/css. WARNING: editing the index.html page and css files can easily have unintended consequences. For this type of customization, you should consider using WordPress (summarized just below).

Notice: clearing the browser's cache (e.g. Ctrl-Shift-Delete) is sometimes necessary after making any of the above changes!

If you get completely stuck, capture a screenshot (take a photo if copying & pasting is not possible) then get in touch so volunteers can help you work it out.

How This All Works: Please see Admin Console's 5 technical overview docs (NEW, as of 2022!) Dynamic Menuing was originally introduced by IIAB/XSCE 6.1, to reduce front-end hand-coding of HTML, by auto-adjusting all http://SERVERNAMES:PORTS links on-the-fly (using browser-side Javascript). More advanced usages are also now possible, if you read about Menu Item Definitions and HTML Fragments — taking note of the latest 2019 additions.

Alternatives: Some prefer a completely different front-end for their Internet-in-a-Box home page, e.g. WordPress (with this possible IIAB plugin), or DokuWiki, or even Moodle etc. Several of these can be enabled in your IIAB's Admin Console (http://box/admin or http://box.lan/admin) -> Configure tab -> Server Portal -> Select Server Home Page — where your choices include:

• /home
• /wordpress
• /wiki

If you do this, don't forget to enable "Check to Enable WordPress" or "Check to Enable DokuWiki" at the top of that page — then on the left click "Save Configuration", followed by Install Configured Options — finally monitoring the result (typically takes 15-25min on a Raspberry Pi 3, 3 B+ or 4) under the Utilities tab -> Display Job Status.

How do I add my own content?

Consider Nextcloud to upload your photos and documents to IIAB.

Consider Calibre-Web to upload your E-Books and videos to IIAB.

Or, if you prefer regular files displayed by IIAB's NGINX web server:

1. Log in to your IIAB's OS with username iiab-admin (e.g. using a screen/keyboard or ssh). Or run multipass shell box if your IIAB is a Multipass virtual machine.
   • If your IIAB is older (built prior to 2024-08-08) make sure it's online then run sudo curl https://raw.githubusercontent.com/iiab/iiab/master/scripts/iiab-root-login > /usr/bin/iiab-root-login && sudo chmod +x /usr/bin/iiab-root-login
2. Run sudo iiab-root-login to set (and enable) user root's sftp password.
3. Install FileZilla Client onto the laptop or PC where your own content is stored.
   • If your content is stored on Android, install sftp client software like Termius or AndFTP (much like FileZilla!) onto your Android device.
   • If your content is stored on an iPhone, install sftp client software like FTPManager (much like FileZilla!) onto your iPhone.
   • Instructions below will assume FileZilla.
4. Use FileZilla to log in to your IIAB:
   • Host: type in your IIAB's actual IP Address e.g. 192.168.0.99 or sftp://10.10.10.10
   • Username: root
   • Password: what you set above!
   • Port: 22
   • Click QuickConnect
5. Use FileZilla to upload your content from (Local site, left side) to IIAB folder /library/www/html/local_content (Remote site, right side).
6. Confirm that your content is uploaded correctly, by browsing to your IIAB, e.g. with a URL like:
   • http://192.168.0.99/usb
   • http://10.10.10.10/usb
   • http://box/usb
   • http://box.lan/local_content

See: How do I add ZIM files, like Wikipedia?

How do I change to Mobile view or Desktop view?

Starting with Internet-in-a-Box 7.0 (#1775) IIAB includes a Mobile/Desktop button, but it's a bit hard to find, so here are basic instructions:

1. Look in the top-left corner of your IIAB home page (e.g. http://box or http://box.lan)
2. Click on the 3 dots (vertical ellipsis)
3. A white popup/dropdown menu will appear
4. Click on its middle icon (which looks like 2 squares, one square on top of the other) to toggle your current browser view between Mobile view and Desktop view!

Notes:

• You can permanently change visual aspects of IIAB's Mobile view and Desktop view within http://box.lan/admin > Content Menus > Properties of Current Menu > [check or uncheck any of the 4 + 4 checkboxes for Description, Extra Description, Sub-menu and Footnote] > Save Menu.

• This can also be done manually, by editing the file /library/www/html/home/home.json

• Separately, many mobile browsers have their own button to force Desktop view — typically found in the top-right under the browser's own vertical ellipsis. Look there for the "Desktop site [ ]" checkbox in Chrome, or the "Request desktop site [ ]" checkbox in Firefox.

How do I provide Solar Power to my school, library, clinic or orphanage?

This is a very hard question depending on the growth path of your electrical needs, local supply chains, electricians' norms within the country in question — and of course maintenance, price, theft patterns, etc.

In places like Haiti this typically revolves around a bank of 12-volt deep-cycle batteries like the Trojan T-105. But don't hesitate to get your feet wet researching and designing a right-sized solar nanogrid suitable for your own community.

In 2019, please see this India solar discussion: eka-foundation/home#24

Tips from earlier years can also still be useful:

How do I provide Wi-Fi (wireless) to all my kids?

If you want a self-contained (single-unit) knowledge hotspot, consider the Wi-Fi capability possibly already built into the computer where you install IIAB. Run iw list and look for "AP" under "Supported interface modes" to see if it's capable of Access Point mode / AP mode (#3057) as would be enabled by hostapd. (If the iw command isn't yet installed, run sudo apt install iw — also see "Can I create a Wi-Fi hotspot using an old laptop?" just below.)

Optionally, you may want to attach a Wi-Fi Access Point to your IIAB. If you want higher-powered Wi-Fi equipment and antenna(e) fully external to your IIAB server, consider approaches such as the cantenna and MeshNet approaches used by Anish Mangal in India.

Most important: take advantage of community support, where volunteers are eager to help on the xsce-devel@googlegroups.com and server-devel@lists.laptop.org mailing lists. There's always tons to learn from the latest Wi-Fi fieldwork success stories.

Also consider unleashkids@googlegroups.com, which is a great place to ask educators about various schools' filtering recommendations, across different age groups and cultures, whether your school is online or off!

Finally, don't hesitate to blog or write up your own specific recommendations, no matter how large or small your school. This vital engineering shop-talk upholds more schools, libraries and orphanages than we can count (building our community repertoire of Wi-Fi wisdom, often far from the Internet, creating "knowledge/learning hotspots" in every sense) in turn allowing kids to take advantage of amazing free Digital Libraries like https://internet-in-a-box.org

See: Can I create a Wi-Fi hotspot using an old laptop?
See: Any other networking tips?

Can I create a Wi-Fi hotspot using an old laptop?

Yes, it is possible to create a Wi-Fi hotspot (using hostapd) on some laptops and netbooks.

NOTE: To determine whether your PC/machine's internal WiFi chip has Linux/distro support for AP Mode (allowing for many students to connect to this hotspot) please run /usr/sbin/iw list and look for * AP under Supported interface modes: or software interface modes — as outlined at #3057.

Equivalent to the above, most IIAB's should have a line in /etc/iiab/iiab.ini saying either can_be_ap = True or can_be_ap = False (PR #3222).

Similarly, you can try running:

 sudo iiab-hotspot-on

REMINDER: If you ever add or remove a USB Wi-Fi adapter (or an entire Wi-Fi router, typically connected over Ethernet), you then need to run:

 sudo iiab-network

You're likely to have good luck with Qualcomm Atheros chipsets — certainly older Atheros chipsets have good support in GNU/Linux (https://wiki.debian.org/ath9k).

February 2019 Example: Testing confirmed that IIAB 6.7's hostapd Wi-Fi hotspot worked with the Qualcomm Atheros AR9285 PCI-Express Wireless device found in an Acer Aspire One.

See: What hardware should I use?
See: Any other networking tips?

How do I change the Wi-Fi hotspot name?

The Wi-Fi hotspot name (also known as SSID) is what most people use to connect to Internet-in-a-Box using their Wi-Fi devices. In other words the name that appears on the air, for your IIAB's wireless network / Access Point / AP.

How to rename it depends on whether your Wi-Fi hotspot is fully-external (such as a wireless router) or rather under direct OS control (e.g. internal, or a tiny USB-connected wireless adapter) :

• If it's fully-external, change its SSID (wireless name) using the documentation that came with the Wi-Fi router.
• If it's under direct OS control, then the Internet-in-a-Box (IIAB) is also the wireless access point:
  • Edit this line in /etc/iiab/local_vars.yml :
    host_ssid: Internet in a Box (quotation marks are OPTIONAL)
    Then run:
    sudo iiab-network
  • You might also log into your server's Admin Console (http://box/admin or http://box.lan/admin) then change the SSID (wireless name) there, under Configure (menu) > Internal Wi-Fi AP > Internal Wi-Fi Access Point Name.
    • This setting will not take effect until you click on Configure (menu) > Install Configured Options (red button), and wait several minutes for all new settings to take effect (monitor status under Utilities (menu) > Display Job Status).
  • WARNING: do not edit /etc/hostapd/hostapd.conf directly, unless you want these custom settings trashed upon updating your Internet-in-a-Box! If you must edit this file despite the danger, consider systemctl restart hostapd to avoid rebooting.
  • Finally you can run sudo iiab-hotspot-on and sudo iiab-hotspot-off which are found in /usr/bin — especially useful if you've used a Raspberry Pi's internal Wi-Fi to install IIAB software and content. See Common Customizations for more detail.

Can I password protect the Wi-Fi hotspot?

Internet-in-a-Box (IIAB) is generally intended as a free library completely open to all!

That said, if you have command-line access to your IIAB using a screen/keyboard or ssh, you can try setting a Wi-Fi password as follows: (assuming your IIAB Wi-Fi hotspot is internal, or is a USB Wi-Fi adapter)

1. Run:

   sudo nano /etc/iiab/local_vars.yml
   

2. Look near Lines 72-73 in your /etc/iiab/local_vars.yml to set these 2 variables:

   hostapd_secure: True
   hostapd_password: ACTUAL_PASSWORD
   

3. Save the file (Ctrl-O) and exit (Ctrl-X).
4. Run sudo iiab-network and confirm that it completes without error (about 3 minutes later).
5. Test it! Further discussion: #3477

See: Any other networking tips?
See: What is local_vars.yml and how do I customize it?

Can I name my server something other than http://BOX.LAN ?

http://box.lan should work in ~99% of all cases, and http://box should work in ~90% of cases; there is no need to change these.

If however a custom name is strongly desired, this can be implemented within each school/library/clinic by editing /etc/iiab/local_vars.yml — and then run sudo iiab-network

Or: log into Admin Console (http://box/admin or http://box.lan/admin) > Configure (menu) > Network Parameters > Host Name > Save Configuration > Install Configured Options (waiting patiently for that to complete under Utilities (menu) > Display Job Status which can take ~20 min on older Raspberry Pi's!)

Many different names have been used in the past, such as http://schoolserver.lan and http://school.lan — anything that resolves locally to http://10.10.10.10 should be sufficient with standard networking (or http://172.18.96.1 if your Internet-in-a-Box pre-dates July 2022). For the record, some of these older names are listed within the following links:

https://github.com/iiab/iiab/blob/master/roles/network/templates/named.unused/school.external.zone.db
https://github.com/iiab/iiab/blob/master/roles/network/templates/named.unused/school.internal.zone.db.j2

See: What is local_vars.yml and how do I customize it?

How do I set a static IP address?

To set a static (fixed) IP address such as 192.168.1.99, use lines like the following in /etc/iiab/local_vars.yml — and then run sudo iiab-network :

 wan_ip: 192.168.1.99
 wan_netmask: 255.255.255.0
 wan_gateway: 192.168.1.254
 wan_nameserver: 192.168.1.254
 wan_try_dhcp_before_static_ip: True

By default this is a FALLBACK static (fixed) IP address, which requires an Ethernet cable and link-light showing. If that cable connects IIAB to an Internet router/cablemodem or similar (that is turned on) IIAB should receive a DHCP IP address within about 30 seconds. Or, if there is no DHCP on the wire, IIAB will set its own IP address (typically on eth0) to 192.168.1.99 per this example, about 45 seconds later.

Specifically, if you keep wan_try_dhcp_before_static_ip: True your /etc/dhcpcd.conf will contain: (on any OS where IIAB sets up /etc/dhcpcd.conf)

 profile static_eth0
 static ip_address=192.168.1.99/24
 static routers=192.168.1.254
 static domain_name_servers=192.168.1.254
 
 interface eth0
 fallback static_eth0

Or if you set wan_try_dhcp_before_static_ip: False your /etc/dhcpcd.conf will contain: (on any OS where IIAB sets up /etc/dhcpcd.conf)

 interface eth0
 static ip_address=192.168.1.99/24
 static routers=192.168.1.254
 static domain_name_servers=192.168.1.254

IN GENERAL, you may need to unplug your IIAB's Ethernet cable and plug it back in before a static IP address takes effect! As such, hard-core traditionalists might also want to add the following to /etc/network/interfaces.d/iiab, to force a static IP address even before the Ethernet "carrier" (i.e. link light) is detected:

 auto eth0
 iface eth0 inet static
     address 192.168.1.99
     broadcast 192.168.1.255
     netmask 255.255.255.0
     gateway 192.168.1.254
     dns-nameservers 192.168.1.254

FYI the above 7 lines also work when nothing at all is added to /etc/dhcpcd.conf, if you want an alternative approach in support of intermittent online updates of your IIAB via Ethernet cable to cablemodem etc (careful though, this unsupported approach is risky as your eth0 will often have 2 IP addresses!)

WHEREAS on Ubuntu, the wan_try_dhcp_before_static_ip variable is currently ignored (i.e. treated as False) and Netplan stores your static IP address settings from /etc/iiab/local_vars.yml into /etc/netplan/01-iiab-config.yaml as follows:

 network:
   version: 2
   renderer: networkd
   ethernets:
     enp0s3:
       addresses:
       - 192.168.1.99/24
       gateway4: 192.168.1.254
       nameservers:
         addresses: [192.168.1.254]
         search: [lan]

Debian 12+ equivalent to be clarified in future (please help us here if you can!)

FINALLY, if IIAB is already installed, also consider IIAB's Admin Console (http://box/admin or http://box.lan/admin) > Configure (menu) > Network Parameters > Check to use a static WAN IP Address instead of DHCP > (enter your) Static WAN IP Address > Save Configuration > Install Configured Options.

Any other networking tips?

If you've just installed Internet-in-a-Box (IIAB) on your home network, here are some great tricks to find its IP Address.

WI-FI RECOMMENDATIONS:

• Please change "host_country_code: US" to the correct country code, in /etc/iiab/local_vars.yml, prior to installing IIAB. If IIAB is already installed, also run sudo iiab-network and then reboot.
  • FYI as of 2022-01-04 this sets the country code in /etc/hostapd/hostapd.conf but not in /etc/wpa_supplicant/wpa_supplicant.conf (right after installing Raspberry Pi OS, you make that happen by running raspi-config -> Localisation Options > WLAN Country). #3097

• IF YOU CONNECT YOUR IIAB'S INTERNAL WI-FI TO THE INTERNET OVER 5 GHz, YOU'LL PREVENT OLDER LAPTOPS/PHONES/TABLETS (WHICH REQUIRE 2.4 GHz) FROM CONNECTING TO YOUR IIAB'S INTERNAL HOTSPOT. This relates to wifi_up_down: True in /etc/iiab/local_vars.yml

• If your IIAB Raspberry Pi is connected to the Internet over Wi-Fi, and you need to change its upstream Wi-Fi connection: run sudo iiab-hotspot-off then sudo raspi-config (to [dis]associate from/to any upstream WiFi access point) then sudo iiab-hotspot-on and reboot — as outlined in Section (2) of Common Customizations.

PLEASE ALSO LOOK OVER:

• The network README outlines the network Ansible role (Ansible playbook) that runs towards the end of IIAB's installation, after all other IIAB apps/services have been installed. You should run it (sudo iiab-network) after all your Ethernet and Wi-Fi network interfaces are plugged in and turned on properly (or unplugged properly!) according to your final deployment topology.

• The high-level IIAB Networking doc reviews Internet-in-a-Box's:
  • Three Network Modes — distinguishing WAN side from LAN side
  • Common Customizations
  • DNS Name Resolution
  • List of Ports / Services
  • Firewall (iptables)

PRO TIP: If you use a USB-to-Ethernet dongle (for upstream Internet, generally) use a permanent marker on the server's correct USB port, so that it's not accidentally moved to another USB port!

Also, do not swap the dongle for another, as each dongle has a fixed/unique MAC address. Worst case if your dongle is lost or broken, you will later (after the new dongle is inserted) need to run sudo iiab-network

FYI Wi-Fi (e.g. for Internet access, etc) is available on the graphical/desktop version of Ubuntu 22.04 LTS (e.g. use its desktop GUI to set SSID and password) — whereas server versions of Ubuntu don't offer Wi-Fi out of the box.

NOTE: To determine whether your PC/machine's internal WiFi chip has Linux/distro support for AP Mode (allowing for many students to connect to this hotspot) please run /usr/sbin/iw list and look for "AP" under "Supported interface modes:" or "supported interface modes" — as outlined at #3057.

Some prefer Gigabyte BRIX (a drop-in replacement Mini PC, instead of the ASUS [formerly Intel] NUC) as an Atheros internal Wi-Fi module can be inserted, to scale beyond the NUC's soldered-in limit of 12 Wi-Fi connections maximum.

Classrooms within 100 meters of your school server can easily be connected using standard Ethernet wiring, or using Wi-Fi repeaters. Outdoor wiring is possible (preferably fiber optic cables below ground) but check with experts to avoid problems with lightning. Beyond 100 meters, a more deliberate tree and branch solution may be needed.

Please ask questions about your specific school's networking/wiring challenges on mailing list unleashkids@googlegroups.com !

What is local_vars.yml and how do I customize it?

To customize your Internet-in-a-Box (IIAB), modify IIAB configuration variables within /etc/iiab/local_vars.yml

It's best to do this prior to installing IIAB, when IIAB's 1-line installer prompts you with "Edit /etc/iiab/local_vars.yml to customize your Internet-in-a-Box? [Y/n]"

Three common example local_vars.yml files are posted for comparison (SMALL-sized, MEDIUM-sized, and LARGE-sized). See also this medical example used by the Wiki Project Med Foundation e.g. for http://med.iiab.me. In addition see our bare bones example, very useful for unit testing of a single IIAB App.

Customize your IIAB installation (and its selection of apps/services, etc) by proceeding as follows:

1. Edit /etc/iiab/local_vars.yml using a text editor such as nano, vi, or emacs.
2. If IIAB is already installed, you MUST then enact your changes:
   • One way to do this is cd /opt/iiab/iiab followed by sudo ./iiab-configure (this can take many minutes on a Raspberry Pi, depending on your changes!)
     • FYI this runs Stage 0, followed by Stages 4-9, WITHOUT running the 'network' role.
     • This is very similar to logging into IIAB's Admin Console (http://box.lan/admin) and then clicking Configure > Install Configured Options — which runs Stage 0, followed by Stages 4-9, WITH the 'network' role. Then monitor the progress, in Utilities > Display Job Status. Or if you prefer the command-line, use: tail -f /tmp/job-<JOB NUMBER>
   • Or, run a (fast) surgical strike using cd /opt/iiab/iiab followed by sudo ./runrole <ROLE NAME> to run a single Ansible role or IIAB Stage.
     • Try sudo ./runrole (without parameters) to see its options, e.g. sudo ./runrole --reinstall <ROLE NAME>
     • Or, run sudo iiab-network to run IIAB's 'network' role.
   • If you must, you can force the running of all Stages 0-9, WITH the 'network' role. Use cd /opt/iiab/iiab followed by sudo ./iiab-install --reinstall
     • DANGER: You may first want to delete /opt/iiab/iiab/iiab_state.yml (to apply more force, At Your Own Risk!)
3. Don't ever modify /opt/iiab/iiab/vars/default_vars.yml, as explained in the IIAB Architecture and IIAB Variables docs.

PRO TIP: Some very practical networking variables are posted in the IIAB Networking document.

See: What services (IIAB apps) are suggested during installation?
See: What are the default passwords?
See: Any other networking tips?
See: Can I upgrade IIAB software?

See: What are the best places for community support?

Is a "Rapid Power Off" button possible for low-electricity environments?

Yes. Small medical clinics and electricity-starved remote libraries typically require this, given that Raspberry Pi computers do not have a physical Power Off button, and it's asking way too much for non-technical operators to power off using the Admin Console.

"apache_allow_sudo: True" is the default in /etc/iiab/local_vars.yml to make this possible.

To power off, any user can then click a URL like: http://box/js-menu/menu-files/services/power_off.php (formerly http://box/common/services/power_off.php)

Whereas most schools do not want this, for obvious reasons — a mischievous student could shut down the Internet-in-a-Box at any time! This is the reason most schools prefer "apache_allow_sudo: False". FYI if do you change this variable's value in /etc/iiab/local_vars.yml, you should then run:

 cd /opt/iiab/iiab
 sudo ./runrole www_options

The "Power Off" button can also be customized in IIAB's Admin Console (http://box/admin or http://box.lan/admin) > Content (menu) > Load Menu > (change the settings in) Properties of Current Menu > Save Menu. More detail on the Content Menus help page and #1689.

See: What is local_vars.yml and how do I customize it?

How do I know what version of IIAB I'm running?

The best way is to run iiab-summary to get a quick ~20 line overview of your Internet-in-a-Box (IIAB) system.

Also, look for iiab_base_ver near the top of your /opt/iiab/iiab/vars/default_vars.yml. This is followed by a number like "8.2" showing the version level (even if you're running a pre-release of that version!) You can also look in /etc/iiab/iiab.env for the line(s) with "IIAB_RELEASE=".

Finally, your iiab branch name is visible if you log into your IIAB's Admin Console (http://box/admin or http://box.lan/admin) and click "About" in the top-right. Look at both fields "Version" and "Commit ID". The "Version" field typically shows "master" (or something like "release-8.2").

The 40-character "Commit ID" string gives more detail. You can compare this to commits within https://github.com/iiab/iiab/commits/master and https://github.com/iiab/iiab/releases — e.g. if you're running the older IIAB 8.1 from December 31, 2023, it would begin with fcb1797.

CAUTION: the letter 'g' is confusingly sometimes added in front of such 7-character githashes (abbreviated from the full 40-character SHA-1 githash) in a few places, like the install image filenames at https://download.iiab.io/8.1/

See: Is a quick installation possible?
See: What are the default passwords?
See: Can I upgrade IIAB software?

Can I upgrade IIAB software?

Please understand this can DESTROY your Internet-in-a-Box if attempted on an older IIAB !

If your IIAB is more than a few weeks old, it's generally much better to install IIAB from scratch at https://download.iiab.io

But if you're willing to proceed AT YOUR OWN RISK (MAKE A BACKUP FIRST) here are instructions, if your IIAB is online:

NEW WAY uses iiab-update, as of July 2024:

• Run sudo iiab-update if you want OS apt updates, in addition to full upgrading of Ansible, Admin Console, Calibre-Web.
• Run sudo iiab-update -f if you want it to run very fast (upgrading IIAB's core and IIAB Calibre-Web, but avoiding slow tasks!)

OLD WAY, please avoid it: (about 15 commands in total!)

 sudo -i

 cd /opt/iiab/iiab
 git config branch.master.remote origin
 git config branch.master.merge refs/heads/master
 git checkout master           # If 'git branch' output shows 'master'
 git checkout -b master        # Or, create 'master' branch & check it out.
 git pull

WARNING: At this point it's best to regenerate your /etc/iiab/local_vars.yml settings and customizations, starting with a fresh copy from one of the 3 local_vars_*.yml files (SMALL-sized, MEDIUM-sized, or LARGE-sized) available in /opt/iiab/iiab/vars

WARNING: You may want to delete /opt/iiab/iiab/iiab_state.yml (to apply more force, AT YOUR OWN RISK!)

Then attempt to upgrade as follows:

 ./iiab-install --reinstall    # Takes about 10-20 min

 cd /opt/iiab/iiab-admin-console
 git config branch.master.remote origin
 git config branch.master.merge refs/heads/master
 git checkout master           # If 'git branch' output shows 'master'
 git checkout -b master        # Or, create 'master' branch & check it out.
 git pull
 ./install                     # Takes about 2-4 min

FYI the 2+2 "git config" lines above are NOT necessary if your .git/config file is already correct in each local repo (/opt/iiab/iiab and /opt/iiab/iiab-admin-console) as explained at https://stackoverflow.com/questions/658885/how-do-you-get-git-to-always-pull-from-a-specific-branch

FYI the 2+2 "git checkout" lines above are NOT necessary if each local repo is already on the master branch. You can run 'git branch' in each of the 2 above (local repo) directories, if you want to see what branch they're on.

See: What is local_vars.yml and how do I customize it?
See: How do I know what version of IIAB I'm running?
See: Can I upgrade or reinstall IIAB apps?
See: Can I get content updates every few months or semester?
See: How do I back up, shrink & copy IIAB microSD cards?

Can I install IIAB apps on an existing IIAB?

Yes, if your IIAB is online! Here are two ways:

1. Log in to Admin Console (e.g. http://box.lan/admin) > Configure > Services Enabled and then:

• Pick the IIAB app(s) you want installed
• Click Save Configuration > Install Configured Options
• Monitor install progress in Utilities > Display Job Status

2. Or at the command-line, run:

 sudo -i
 cd /opt/iiab/iiab
 ./runrole <APP OR ROLE NAME>

See: What services (IIAB apps) are suggested during installation?
See: What are the default passwords?
See: Can I upgrade or reinstall IIAB apps?

Can I upgrade or reinstall IIAB apps?

1) Most IIAB Apps can be reinstalled to the very latest available version when you're online, as follows:

 sudo -i
 cd /opt/iiab/iiab
 ./runrole --reinstall <APP OR ROLE NAME>

WARNING: Make a backup of ALL data and content first, if you do not want to take risks!

SPECIFICALLY: Each app does this a bit differently, but the general rule is to (try) to preserve all content and user data during an app reinstall.

CLARIFICATION 1: IIAB does not support offline reinstalls, as a general rule. In some cases however, you can run ./runrole --reinstall [APP OR ROLE NAME] even when offline, to reinstall certain apps to a cleaner/known state, e.g. whatever app version was most recently downloaded to your system.

CLARIFICATION 2: What is installed (and implicitly, what is not) can be viewed within /etc/iiab/iiab_state.yml

2) HIGH RISK: If your IIAB was recently installed, you can try to reinstall all of your apps to the latest available versions, and reinstall IIAB itself, as follows: (this could take a while!)

 sudo -i
 mv /etc/iiab/iiab_state.yml /etc/iiab/iiab_state.yml.old
 cd /opt/iiab/iiab
 git pull    # THIS LINE AT YOUR OWN RISK!
 ./iiab-install --reinstall

WARNING: Make a backup of ALL data and content first, if you do not want to take risks!

CLARIFICATION: IIAB does not support offline reinstalls, as a general rule. In some cases however, the above will still work even when run offline.

3) Prior to February 2020, IIAB implementers were advised to (at their own risk) individually delete the following files or directories, to attempt an upgrade or reinstall of these common IIAB apps. And then run "cd /opt/iiab/iiab" then "./iiab-install --reinstall" or "./runrole --reinstall <ROLE NAME>" :

• /library/www/nextcloud/version.php WAS /opt/nextcloud/version.php (Nextcloud version stored therein; reinstalls are easiest if you "sudo mysql" then "DROP DATABASE nextcloud;" (confirmed by "SHOW DATABASES;") and delete the entire /library/www/nextcloud WAS /opt/nextcloud). SEE ALSO: https://docs.nextcloud.com/server/latest/admin_manual/maintenance/update.html AND https://docs.nextcloud.com/server/latest/admin_manual/maintenance/upgrade.html
• /opt/iiab/kiwix/bin/kiwix-serve (Run "/opt/iiab/kiwix/bin/kiwix-serve --version" to show kiwix-tools version number, since 3.0.2 on 2020-02-13.)
• /opt/iiab/moodle/config-dist.php (Moodle version stored in /opt/iiab/moodle/version.php — major upgrades may require deleting /opt/iiab/moodle and /library/moodle, dropping the database using "dropdb -U postgres moodle" — and if nec upgrade PostgreSQL below. Optionally, take a look in /library/pgsql-iiab/ outlined just below!)
• /library/pgsql-iiab/pg_hba.conf (PostgreSQL version shown by "psql -V" client or "[PATH]/bin/postgres -V" server; major upgrades might require deleting or upgrading data directory /library/pgsql-iiab)
• /library/ka-lite/database/data.sqlite then "systemctl restart kalite-serve", then you may need to re-register and delete/re-download KA Lite's English "content pack" at http://box:8008/update/languages/ (KA Lite version stored in /library/ka-lite/httpsrv/static/docs/index.html ; major upgrades also require deleting /usr/local/kalite)
• /library/dokuwiki-<version>/VERSION if reinstall required (DokuWiki version shown by "ls -l /library/dokuwiki")
• /usr/local/osm (sometimes needed to force a fresh install of OSM / OpenStreetMap)
• /usr/bin/calibre AND move old .deb's from /opt/iiab/downloads if on RPi (Calibre version shown by "calibre-server --version")
• /library/calibre-web/metadata.db deletion forces default settings, and restores a minimal metadata.db (1. version is implied by "cd /usr/local/calibre-web; git log" — or since early 2020 "cd /usr/local/calibre-web-py3; git log" — which can also be compared to the githashes shown at https://github.com/janeczku/calibre-web/releases 2. Calibre-Web will let you check from the command-line in future, per #1624 3. Log in then click "Admin" at the top of http://box/books, at the bottom the current version number is listed, so long as you're on the "stable update channel" which is the default)
• /library/games/minetest and/or /library/games/0.4.17.1 version number may vary! (delete these dirs as nec, to help force a reinstall of Minetest)
• /usr/libexec/iiab-startup.sh (delete this if you want to upgrade to IIAB's latest e.g. /opt/iiab/iiab/roles/2-common/templates/iiab-startup.sh)
• [Deletion of /library/wordpress is optional; online-upgrade is automatic/mandatory when running "./iiab-install --reinstall" or "./runrole wordpress" in /opt/iiab/iiab] Also Note: WordPress increasingly upgrades itself, when used online (WordPress version stored in /library/wordpress/wp-includes/version.php; major upgrades may also require you to drop database "iiab_wp" by running "mysql" as root, and then "drop database iiab_wp;" confirmed by "show databases;". Dropping the db is an easy way to change the language of WordPress' user interface — or this can also be done in http://box/wordpress > Settings > General > Site Language — and if the desired language is not one of your OS's installed locales, WordPress will try to download it.)
• [Deletion of /library/mediawiki-ACTUAL.VERSION.NUMBER/LocalSettings.php no longer required; BUT database schema changes on almost every upgrade. So: automatic installation of latest (during "./runrole --reinstall mediawiki") generally requires you first drop or update mysql "iiab_mediawiki"; for database/schema upgrades read about update.php in MediaWiki Manual's Upgrading FAQ] (MediaWiki version visible within http://box.lan/wiki/Special:Version and in dir name e.g. /library/mediawiki-ACTUAL.VERSION.NUMBER, as installed by /opt/iiab/iiab/roles/mediawiki/defaults/main.yml; finally feel free to delete older dirs of the form /library/mediawiki-OLD.VERSION.NUMBER after upgrading)
• [Upgrading a very recent version of Lokole MAY require deletion e.g. with "rm -rf /library/lokole"] In any case, attempt to install the latest Lokole using: "./runrole --reinstall lokole". (Lokole version is shown by "grep ^Version /library/lokole/venv/lib/python3.*/site-packages/opwen_email_client-*/*" [METADATA on some OS's, PKG-INFO on others]. If removing Lokole entirely, you may also want to clear out its Apache config files: "rm -rf /library/lokole /etc/apache2/sites-*/lokole.conf")
• [No file deletion of /opt/elgg-ACTUAL.ELGG.VERSION/index.php required; online-upgrade is automatic/mandatory during "./iiab-install --reinstall"] (Elgg version shown by "ls -l /opt/elgg")
• [No file deletion required; apt update then apt install kolibri can work to upgrade Kolibri since August 2022. CAUTION: Administrators need to type in the username kolibri when apt upgrading Kolibri as of 2022, due to Kolibri bug learningequality/kolibri-installer-debian#115] (Kolibri version shown by /usr/bin/kolibri --version — a full wipe/purge of Kolibri can be accomplished by apt purge kolibri and then removing [1] /library/kolibri [2] /etc/kolibri and [3] /usr/bin/kolibri as nec.)
• [No file deletion required; online-upgrade or offline-reinstall is automatic/mandatory during "./iiab-install --reinstall"] (phpMyAdmin version shown by "ls -l /opt/phpmyadmin")
• [No file deletion required; though in the past /library/www/html/sugarizer/index.html had to be moved] (Sugarizer version now shown by "ls -ld /opt/iiab/sugarizer*" or in the past, "ls -l /library/www/html/sugarizer"; major upgrades might require deleting directories /opt/iiab/sugarizer-server/node_modules and MongoDB's entire /library/dbdata/mongodb)
• [No file deletion required; online-upgrade is automatic/mandatory during "./iiab-install --reinstall" or "./runrole --reinstall gitea"] (High-level Gitea version is shown by "ls -l /library/gitea/gitea" — point release is shown at bottom-left of http://box/gitea)
• After JupyterHub is installed, here are 2 ways to check the version number: (1) ls -d /opt/iiab/jupyterhub/lib/python3.*/site-packages/jupyterhub-* (2) http://box/jupyterhub -> log in (e.g. Admin/changeme) -> File menu -> Hub Control Panel -> Admin menu. If you want to reinstall JupyterHub from scratch, first delete directory /opt/iiab/jupyterhub — and read more about JupyterHub operations here: https://github.com/iiab/iiab/blob/master/roles/jupyterhub/README.md

WARNING #1: Data loss of kids', teachers' and users' personal materials is always possible, ALWAYS back up any relevant databases first!

WARNING #2: Beware you will likely lose settings that you've set within Internet-in-a-Box's Admin Console (http://box/admin or http://box.lan/admin).

WARNING #3: Testing is ongoing to make sure this works sufficiently in typical situations like these 2 below, ensuring that a wholesale revert to default settings is at least plausible:

1. When intermittently online, an operator may want an online upgrade of a server app to the very latest available version.
2. When completely offline, an operator might want an offline reinstall of a server app using its original zipfile-or-similar installer that resides within /opt/iiab/downloads

Can I get content updates every few months or semester?

Great question, keeping in mind the near-impossibility of downloading large Content Packs to remote locations in the developing world.

Despite these obstacles, remote upgrades are becoming increasingly possible now that high-bandwidth connections are available within cities in the developing world. For Example: bringing a rural IIAB device into the city for a night (or a few days) to plug it into an online cablemodem, can be a very efficient and affordable way to update content — particularly within countries that offer unlimited downloads, at a fixed monthly rate.

Notwithstanding, terabyte download costs explain why drop-shipped hard drives containing "complete content catalogs" are often still more economic and efficient than downloading.

Please watch the HOW-TO videos on Internet-in-a-Box's YouTube channel (several available as .mp4 and .WebMD) to get up to speed with downloading & installing content to your IIAB!

On the high end, IIAB's Admin Console (http://box/admin or http://box.lan/admin > Install Content) supports piecewise incremental content updates, e.g. for schools with very high-bandwidth Internet connections. Note that older Content Packs can be individually be removed within Admin Console (http://box.lan/admin) > Manage Content, when there's a need to free up disk space. Likewise IIAB Apps such as KA Lite and Kolibri offer administrative interfaces, supporting deletion of lessons/videos within their environments, as well as downloading new ones.

As a practical matter, remote schools may receive larger updates via hard drive or USB memory stick every semester or every year — e.g. flown in or driven in or mailed in by a partner. Empowering them with new maps / encyclopedias / E-Books / video lessons — as well as other content and apps.

Keep in touch as new options evolve! Please make contact to keep up with other communities' offline content collections and recommendations.

What security tips exist?

Please read more about the iiab-admin Linux user and group, which allow you to log in to IIAB's Admin Console:

• https://github.com/iiab/iiab/tree/master/roles/iiab-admin
• https://github.com/iiab/iiab-admin-console/blob/master/Authentication.md

Some IIAB installations include ssh keys which permit developers to log into your machine, to enable remote support during Beta programs and similar. You can disable this feature by running terminal command sudo rm /root/.ssh/authorized_keys

Whether running your server online or offline, please see Security and help us contribute to this evolving knowledge & repertoire of 21st century hygiene, thanks to professional volunteers from many backgrounds.

Can I use HTTPS / TLS / SSL instead of HTTP?

This is impossible with an Internet-in-a-Box (IIAB) set up in a permanently OFFLINE school or community, as the World Wide Web Consortium sadly does not allow this (reasons explained here). Worse, those who try to force this with self-signed web server certificates find that everyday users (the world's poorest citizens, and others!) do not tolerate the complexity and hassle of scary browser pop-up overrides.

If however you're setting up an IIAB that will be ONLINE (with regular Internet access) then HTTPS encryption is thankfully easy to set up:

1. Set gui_port: 443 in /etc/iiab/local_vars.yml preferably prior to installing IIAB. (Or if IIAB software is already installed, modify and then run /usr/bin/iiab-gen-iptables so that your iptables firewall opens up port 443 instead of port 80.)
2. After IIAB software is installed, edit /etc/nginx/server.conf to remove or comment out server_name $hostname; — instead set your actual domain name e.g. server_name MY-DOMAIN.ORG;
3. Run:

   sudo -i
   apt install certbot python3-certbot-nginx
   certbot --nginx -d MY-DOMAIN.ORG
   

4. The above certbot command asks you a few simple questions to help arrange auto-renewal of your web certificate every 60-to-90 days, before it modifies your /etc/nginx/server.conf (check this file carefully for any further manual modifications that you might require!)
5. If you modified any NGINX (web server) configuration files, run nginx -t && nginx -s reload to validate then "reload" NGINX.
6. Test HTTPS access to your IIAB, by browsing to your actual Internet domain name, e.g. https://MY-DOMAIN.ORG
7. If you later need to manually renew your web certificate (e.g. if its Internet access is very unreliable) then consider commands like: certbot renew --dry-run, certbot renew --force-renewal or simply certbot renew

How can I remotely manage my Internet-in-a-Box?

1. Raspberry Pi Connect allows you to connect remotely from a web browser, if your IIAB was built using Raspberry Pi OS: (May 2024 blog post, June 2024 blog post, forum)

A. Create a Raspberry Pi ID at https://id.raspberrypi.com and a Connect account at https://connect.raspberrypi.com

B. On your Raspberry Pi, run either apt install rpi-connect if you need full graphical screen sharing — or choose apt install rpi-connect-lite which only supports shell access. Reboot your Raspberry Pi, either way!

C. Link any Raspberry Pi to your Connect account: click the Connect icon in the top-right of Raspberry Pi OS's graphical desktop — or run rpi-connect signin at the Raspberry Pi OS command-line. Finish linking your Raspberry Pi, by visiting the verification URL.

D. Enable user lingering to make any Raspberry Pi remotely accessible even when your local user account isn’t logged in there. FYI "Connect signs communication with your [Raspberry Pi hardware] serial number. Moving your SD card between devices will sign you out of Connect."

2. You can use https://remote.it to remotely support almost any IIAB. Simply run sudo iiab-remoteit at the Linux command-line (of any IIAB that is online) and it tells you what to do. As of 2024, 5 IIAB devices can be managed for free (their personal / non-commercial plan) and larger numbers for $10+/month. Full instructions are here: https://github.com/iiab/iiab/tree/master/roles/remoteit

3. As of September 2024, IIAB not only includes the tailscale command, but also makes this modern/mesh VPN dead simple for newbies and newcomers, using the iiab-vpn command. Please contact us by email (holt@unleashkids.org) to introduce yourself — so we can arrange a cryptographic key for users in need and/or contributors doing good work!

4. Smaller-scale implementers may prefer traditional Linux-and-ssh arrangements across firewalls using https://ngrok.com or https://dataplicity.com or https://www.zerotier.com — possibly in combination with router port-forwarding and Dynamic DNS services like No-IP (https://noip.com).

5. In all 4 above cases, consider low-bandwidth screen sharing using the screen command as explained in IIAB's Technical Contributors Guide.

6. Beginners may prefer graphical screensharing via Zoom, Google Meet, or TeamViewer "unattended access" especially if you have a graphical desktop environment on your Internet-in-a-Box. This can also be priceless when mentoring/learning at a distance, thanks to TeamViewer's screen-sharing, keyboard-sharing and mouse-sharing — helping to onboard new operators who aren't yet comfortable with GNU/Linux and its command line tools. In a graphical desktop environment, simply install TeamViewer, which by default randomizes TeamViewer's password (needed for remote access) every time TeamViewer is launched, preserving local operator control.

And if you want, enable TeamViewer's fully "unattended access" by setting a more permanent password for remote access here: TeamViewer > Extras > Options > Security > Personal Password (for unattended access).

Raspberry Pi: If you're using the Raspberry Pi OS (either the "Lite" server edition, or the "with desktop" edition including a graphical desktop environment) then you probably want the minimal TeamViewer Host. Or consider their TeamViewer Full Client. Either way, it works as a single-click install (or "apt install ./FILENAME.deb", or "dpkg -i FILENAME.deb; apt-get -f install") and includes seamless ongoing upgrades via apt.

Bonus: headless installation/configuration is also now supported (e.g. on Raspberry Pi OS Lite) with "teamviewer info" "teamviewer passwd <ACTUAL-PASSWORD>" and "teamviewer help" per https://community.teamviewer.com/English/kb/articles/6318-how-to-install-teamviewer-for-linux.

Note: Developers' ssh keys may be included with IIAB install images, to facilitate remote support during Beta programs and similar. Read "What security tips exist?" if you want instructions to remove these keys.

How do I view usage statistics?

Please consider AWStats and Matomo in the table above.

EXAMPLE — to help teachers understand which ZIM files are most popular:

1. Ensure the following lines are in /etc/iiab/local_vars.yml

   kiwix_install: True
   kiwix_enabled: True

2. If the above lines are newly added, run cd /opt/iiab/iiab then sudo ./runrole kiwix
3. Visit http://box/awstats to view stats:
   • User visits to http://box/kiwix/ZIMNAME/ are recorded
   • User visits to http://box:3000/kiwix/ZIMNAME/ (formerly http://box:3000/ZIMNAME/) are NOT recorded

Background:

• PR #585 Proxy for Kiwix
• #1268 AWStats
• #1762 IIAB Community Analytics framework, above & beyond AWStats
• PR #3304 Matomo

See: What services (IIAB apps) are suggested during installation?
See: What is local_vars.yml and how do I customize it?

How do I add ZIM files, like Wikipedia?

Please read "How do I customize my Internet-in-a-Box home page?" Several HOW-TO videos on Internet-in-a-Box's YouTube channel (some available as .mp4 and .webm) can also help you install content onto your IIAB:

1. To download ZIM files, log in to your Internet-in-a-Box's (IIAB) Admin Console (http://box.lan/admin) -> Install Content -> Get ZIM Files from Kiwix

2. Or, if you already have content on hand (like ZIM files or OER2Go/RACHEL modules) on a portable USB disk or USB flash drive, insert the USB drive into your Internet-in-a-Box (IIAB). Then use your IIAB's Admin Console (http://box.lan/admin) -> Install Content -> Manage Content to copy the content you need, installing it onto your IIAB:

• The USB drive must have the same /library layout as your IIAB:
  • ZIM files belong in /library/zims/content
  • OER2Go/RACHEL modules belong in /library/www/html/modules

• Copying content works in both directions! (You can also copy ZIM files and OER2Go/RACHEL modules from your IIAB to the USB drive — to bring content to another IIAB, community or school.)

3. Or, if you prefer the command-line, download the ZIM file you want (e.g. from https://download.kiwix.org/zim/) directly to your IIAB's /library/zims/content — for example:

 cd /library/zims/content/
 sudo wget https://download.kiwix.org/zim/wikipedia/wikipedia_ht_all_maxi_2024-06.zim

Then run /usr/bin/iiab-make-kiwix-lib to update your IIAB's ZIM file index:

 sudo iiab-make-kiwix-lib

While rarely necessary, if you need to completely rebuild your IIAB's ZIM file index, run:

 sudo iiab-make-kiwix-lib -f

4. Finally, whichever approach you choose above, test that your new ZIM file(s) are browsable at http://box/kiwix and that search features (at the top-right of the page) are working!

IN FUTURE:

• Students may be able to take small ZIM files home with them, on their own phones.
• Teachers might be able to auto-display (or auto-install) ZIM files from USB sticks/drives inserted into any IIAB: #857 #1538

LEGACY ZIM FILES CLARIFICATION: Most all ZIM files generated since mid-2018 contain an internal search index. There are a few rare exceptions however. In some cases title search works but full text search is impossible, because no such index was ever built. In yet other cases (some older/legacy ZIM files) the ZIM comes with associated index files that must be placed in /library/zim/index — please see: https://github.com/iiab/iiab/tree/master/roles/kiwix#readme

KA Lite Administration: What tips & tricks exist?

Khan Academy videos and exercises are extremely popular thanks to KA Lite, which stores these famous videos (.mp4) and thumbnails (.png) within /library/ka-lite/content, and can be customized in different ways. Note this folder also contains 3 critical subfolders, after you've installed KA Lite's mandatory English content pack as part of a new install: (IIAB's 1-line installer does this for you!)

• assessment (836 MB on a new install)
• locale (16 KB on a new install)
• srt (subtitles, 105MB on a new install)

To change KA Lite's Admin and user-level passwords, see "What are the default passwords?" above.

For starters, log into http://box:8008 as the Admin user, and learn how to install language packs and then download/delete videos in different languages.

Instead of the above, many prefer torrenting the compressed KA Lite videos (available in 7 common languages, also here) as their storage footprint is more than 3X smaller!

Traditionally Windows users use BitTorrent client software like Tixati, and Linux users use command-line BitTorrent tools like aria2 (trying --force-sequential or "aria2c -Z URL1.torrent URL2.torrent" to download several). Or, a visual interface to BitTorrent can now be used as part of your Internet-in-a-Box:

A. Internet-in-a-Box can now kickstart the BitTorrent download(s) for you, if you set transmission_install and transmission_enabled to True in /etc/iiab/local_vars.yml and pick the KA Lite language(s) you need. Install and launch Transmission by running cd /opt/iiab/iiab then sudo ./runrole transmission then sudo iiab-network

B. Monitor your BitTorrent download(s) at http://box:9091 using Admin/changeme until download is confirmed complete (can take hours if not days!)

C. Carefully move all videos/thumbnails from /library/transmission into /library/ka-lite/content (DO NOT OVERWRITE SUBFOLDERS assessment, locale, srt !)

D. Log in to KA Lite at http://box:8008/updates/videos/ using Admin/changeme then click "Scan content folder for videos" (can take many minutes!)

Separately, you can run "/opt/iiab/iiab-factory/content/khan/ka-scan" to remove obsolete videos, which will be moved to /library/ka-videos/obsolete to help you free up space!

More advanced administrators can take a look at the scripts in /opt/iiab/iiab-factory/content/khan and /opt/iiab/iiab-factory/box/generic contributed by Tim Moody.

In general, you can restart the KA Lite service using "systemctl restart kalite-serve" if attempting such changes under the hood. Three common such examples follow:

Mandatory English Pack taking too long to download? Mysteriously, KA Lite's mandatory 1GB (929,916,955 byte) English Pack can take hours to download over certain ISP's and network environments, when installing it using the official command "kalite manage retrievecontentpack download en". Speedier 3-Step Alternative If So: (1) Download en.zip manually (using another ISP if necessary) from https://pantry.learningequality.org/downloads/ka-lite/0.17/content/contentpacks/en.zip using wget or any browser. (2) Install it by running "kalite manage retrievecontentpack local en en.zip" (it's no longer necessary to type in "export KALITE_HOME=/library/ka-lite", as /usr/bin/kalite is now a bash wrapper to "venv" that does that automatically). Brief Help is available if you enter "kalite manage help retrievecontentpack". (3) Run "du -hs /library/ka-lite/content/" to verify that 940MB or more has successfully been installed there (and log in as Admin to http://box:8008 -> Manage -> Language to be 100% sure!)

Multilingual? Consider running 2 or 3 instances of KA Lite on the same Internet-in-a-Box server, e.g. we sometimes put English on port 8008, Spanish on port 8007, and French on port 8006. Examine the /opt/iiab/iiab-factory/content/khan/mk-other-kalite script if you too want *direct* access to Spanish videos in /library/ka-lite-es, or *direct* access to French videos in /library/ka-lite-fr, etc. Typically implementers run "mk-other-kalite es 8007" or "mk-other-kalite fr 8006" (make sure your mk-other-kalite is up-to-date!)

If you do this, make sure your IIAB's firewall (iptables) has the ports open that you need for "campus-wide" (WAN side) access to these materials. Make any changes you need to the ports_externally_visible: variable in /etc/iiab/local_vars.yml and consider these 2 older examples: open ports below 8008, open up port 4244.

Monolingual in Spanish or French or similar? Fool /opt/iiab/iiab-admin-console/roles/js-menu/templates/config.json.j2 (live at /library/www/html/js-menu/config.json) by changing the line with "es-kalitePort" from 8007 to 8008 — or change the line with "fr-kalitePort" from 8006 to 8008 (this works to get rid of English, even if "en-kalite-Port" remains 8008). A separate/crude hack to get other languages to work with ports 8006 or 8007 is to put "lang": "fr", or "lang": "es", in the .json file in the /library/www/html/js-menu/menu-files/menu-defs directory.

More Documentation? Please see the original KA Lite README.

Changing Calibre's port is similar: Modify calibre_port (e.g. from port 8080) in /etc/iiab/local_vars.yml prior to installing IIAB, which you can later confirm in /library/www/html/js-menu/config.json

WordPress & Moodle Administration: What tips & tricks exist?

How do I set the WordPress URL (like http://box/wordpress) so it works for everyone?

• Make sure the very first login to WordPress uses the URL that your community wants to use long-term (e.g. http://box.lan/wordpress on the LAN-side of IIAB, or a campus-wide URL on the WAN-side of IIAB). WordPress will "permanently" hard-code the URL from then onwards.

• If you must change it later, follow the WordPress instructions for Changing The Site URL which offers 5 different ways to get this done, 2 of which involved editing /library/wordpress/wp-config.php

• Please review your options at #3071.

How do I optimize Matomo or PBX or WordPress for high-traffic usage?

• Set nginx_high_php_limits: True in /etc/iiab/local_vars.yml (NOTE: IIAB enables these higher settings for Moodle and Nextcloud automatically, as of August 2023.)

• Then run cd /opt/iiab/iiab followed by sudo ./runrole www_options and then reboot.

• Of course, make sure your Internet-in-a-Box has enough RAM and disk! Background: #1147

Optionally you might further customize the 6 settings {upload_max_filesize, post_max_size, max_execution_time, max_input_time, memory_limit, max_input_vars} in both /etc/php/<ACTUAL VERSION NUMBER>/*/php.ini files (reboot if so!) This is best done prior to IIAB's install, within /opt/iiab/iiab/roles/www_options/tasks/php-settings.yml

How do I copy a complete installation of WordPress to another Internet-in-a-Box?

• Please consider Eric Nitschke's instructions (#1287) using Wordpress plugin "All-in-One WP Migration".

How do I integrate IIAB Apps and Content Packs (and custom menuing!) into a larger WordPress site?

Please see Joshua Kanani's WordPress plugin instructions. Thank you for providing feedback in support of this emerging effort!

How do I set the Moodle URL (like http://box.lan/moodle) so it works for everyone?

• Most prefer to modify /opt/iiab/moodle/config.php including their customized school URL in a line like $CFG->wwwroot = 'http://192.168.0.100/moodle'; or $CFG->wwwroot = 'http://myschool.mydomain/moodle';
• Please review your options at #941 and #3071.

How do I add TuxMath?

Run this:

 sudo -i
 cd /library/www/html/modules
 git clone https://gitlab.com/Afrikalan/tuxmath-js --depth 1
 rm -rf tuxmath-js/.git*

Using Admin Console, set up a menu item on your IIAB home page, to help students access http://box/modules/tuxmath-js

How do I add Scratch-like “Snap!” ?

Run this:

 sudo -i
 cd /library/www/html/modules
 git clone https://github.com/jmoenig/Snap en-snap -b v10.2.4 --depth 1
 rm -rf en-snap/.git*

Using Admin Console, set up a menu item on your IIAB home page, to help students access http://box/modules/en-snap (or similar!)

Examples:

• en-snap.json
• es-snap.json
• fr-snap.json

Captive Portal Administration: What tips & tricks exist?

When installed on Raspberry Pi OS, Internet-in-a-Box (IIAB) offers the option of a basic Captive Portal since IIAB 6.7, so new users don't have to type in URL's (like http://box, http://box.lan or http://10.10.10.10) into their browser.

This is similar to pages that appear automatically when you connect to Wi-Fi in airports/hotels/restaurants. It helps provide immediate access to those who have trouble typing in URL's, or live in countries that do not use Latin-based languages in their URL's.

DEVELOPERS: please see the Captive Portal README.md for a high-level summary of its mechanics and how it works, then look through the code here: https://github.com/iiab/iiab/tree/master/roles/captiveportal/

CAUTION: IIAB's Captive Portal is experimental, so you need to try it on the smartphones and client devices most common in your community. Please also see these older Known Issues.

Captive Portal is installed but not enabled by default in IIAB 8.2. Here are instructions to enable it:

• sudo -i

• Run 'nano /etc/iiab/local_vars.yml' to set both these variables: (typically around Lines 379-380)

 captiveportal_install: True
 captiveportal_enabled: True

• cd /opt/iiab/iiab

• ./runrole captiveportal     # Or, if necessary: ./runrole --reinstall captiveportal

Conversely, note that many schools prefer to disable Captive Portal entirely, which can be done as follows:

• sudo -i

• Run 'nano /etc/iiab/local_vars.yml' to set this variable to False: (typically around Line 342)

 captiveportal_enabled: False

• cd /opt/iiab/iiab

• ./runrole captiveportal

As new phones and devices appear, different browsers on different versions of Android, Windows, iOS and Linux will require usability (UX) refinements and we'd love your help!

If you face Captive Portal issues, please send us screenshots (or photos of any error messages!) by clicking "New issue" in the top-right of: https://github.com/iiab/iiab/issues — don't forget to include the make/model of your client device along with the specific version of its OS and browser!

Finally if you're someone who can improve IIAB's Captive Portal functionality directly, please look over checklist #1182 and explore its Ansible & Python code here.

See: Any other networking tips?
See: What is local_vars.yml and how do I customize it?

Is campuswide access possible for all server apps?

No: several of these server apps fail when accessed over the WAN side of an Internet-in-a-Box, but work well over the LAN side or internal-WiFi of an Internet-in-a-Box.

Still: WordPress, Nextcloud, Moodle and others can be modified using an evolving arsenal of tricks that we hope you too can help refine!

The challenge is to get the most urgently needed campuswide LMS-like apps working well enough for campus-like environments (rather than perfectly in all situations, unfortunately not possible given modern cybersecurity threats!)

ASIDE: efforts are ongoing to make snappy/mnemonic URL's (like http://box/books) in support of teachers' and medical clinics' desires to rapidly onramp information literacy among new users.

See: What security tips exist?
See: WordPress & Moodle Administration: What tips & tricks exist?

Is there a file like AUTOEXEC.BAT to run jobs on boot?

Many Linux OS's offer /etc/rc.local — Internet-in-a-Box (IIAB) recommends /usr/libexec/iiab-startup.sh if you're concerned that local operators might overwrite rc.local

/usr/libexec/iiab-startup.sh is put in place by iiab-startup.yml at the end of Stage 2 during IIAB's installation.

Can I permanently attach an external USB drive, to add more content?

If your Internet-in-a-Box (IIAB) internal storage is full, here's a way to place additional content on an external USB drive or USB memory stick.

Format the USB drive with the ext4 filesystem:

 mkfs.ext4 /dev/sdX    # Or if the device is partitioned: mkfs.ext4 /dev/sdXN

Before running the above, change 'X' (and 'N' if necessary) to correspond to your actual USB drive. You can uncover this (its device name) by running commands like lsblk or blkid with df -h.

Label the USB drive (e.g. "IIAB-LIBRARY-EXT" in this case) again filling in 'X' (and 'N' if necessary) before you run:

 e2label /dev/sdX IIAB-LIBRARY-EXT    # Or if the device is partitioned: e2label /dev/sdXN IIAB-LIBRARY-EXT

Put this line (using the same label as above) into your IIAB's /etc/fstab

 LABEL=IIAB-LIBRARY-EXT  /library-ext  ext4  defaults,nofail  0  0

Alternatively, a popular option is to put ALL your content in the USB drive's own top-level library folder. (This works well with Admin Console -> Install Content -> Manage Content to import/export content.) BONUS: If you choose this approach, you can avoid creating the symbolic link[s] mentioned further below!

 LABEL=IIAB-LIBRARY-EXT  /library-ext  ext4  defaults,nofail       0  0
 /library-ext/library    /library      none  defaults,bind,nofail  0  0

Either way, create the needed mount point on your IIAB, by running:

 mkdir /library-ext

After you've tested that your USB drive automounts correctly on boot, create any symbolic link(s) you need — so that IIAB can find any Content Packs you've placed on the external USB drive.

Example command: (if for example you placed all your OER2Go/RACHEL modules onto the external USB drive, so they appear as /library-ext/www/html/modules/ when mounted)

 ln -s /library-ext/www/html/modules/ /library/www/html/modules

CLARIF 1: This example assumes you're copying Content Packs onto the external USB drive so they'll appear under /library-ext using the very same layout of sub-folders that IIAB uses for content within /library on its internal drive.

CLARIF 2: If this USB drive is plugged into another Linux computer, the above example folder might automount differently, e.g. appearing as /media/usb/www/html/modules

CLARIF 3: Use the very same IIAB to set up and verify that the external USB drive's file ownership and read/write permissions work (e.g. use Linux commands chown and chmod if necessary).

CLARIF 4: When copying large Content Packs, we strongly recommend the rsync -av command, so that files are not lost and the copy process can continue if interrupted — while preserving ownership and timestamps.

CLARIF 5: Another way to do this (e.g. on a more temporary basis) is "bind mounting" as mentioned at #2679, #3106 and "What is a bind mount?"

CLARIF 6: If your Linux OS has a graphical desktop, it's common to see popup message warnings like:

 Unable to mount 128 GB Volume
 Device /dev/sdb1 is already mounted at '/media/usb0'.

It's safe to ignore these messages. Or you can make these popup messages go away, typically by clicking through your graphical File Manager's preferences or OS settings, and unchecking the box for "Mount removable media automatically when they are inserted" or "Automatically mount removable media when inserted and on startup." #86

Can I install IIAB onto a USB drive?

This can fail with consumer-grade hardware, because the boot device's USB 3.0 frequencies (e.g. radiating from a USB flash drive, Raspberry Pi "hat" or other peripheral — especially those lacking a ferrite RF choke and/or lacking proper USB3 cable shielding) very often interfere with the Raspberry Pi's internal Wi-Fi.

As explained in #2638, raspberrypi/firmware#1430 and this 2012 Intel White Paper:

 USB 3.0 Radio Frequency Interference Impact on 2.4GHz Wireless Devices
 
 https://www.usb.org/document-library/usb-30-radio-frequency-interference-impact-24-ghz-wireless-devices (PDF)

DO THIS FIRST: A 1st order test of the quality of your hardware is to set up USB 3.0 boot (do this prior to installing IIAB) then connect to your building's 2.4GHz (NOT 5GHz !) Wi-Fi — without an Ethernet cable! Then carefully test web/online tasks like running apt update, downloading large files, ping mit.edu, etc — evaluating packet loss over many minutes to be sure. (If your hardware/layout cannot function reliably as a Wi-Fi client device, don't even bother trying to set it up as an Internet-in-a-Box learning hotspot!)

This can work however, if you've acquired the right RF-shielded hardware, and set it up carefully. So if you've carefully validated your hardware/setup's ability to work with 2.4GHz Wi-Fi, then installing Internet-in-a-Box (IIAB) onto a USB stick or USB drive is possible — e.g. by following Shanti Bhardwa's Steps 1 to 14 (#2585) — or Dirk Uys' Steps 1 to 14 (#1799) for Raspberry Pi 3-and-higher.

For Raspberry Pi Zero W, Step 17 will also be necessary (copying bootcode.bin to the first partition).

THEFT WARNING: Of course there is a risk your USB (flash or hard disk) drive might be stolen, as there's always a temptation for others to "borrow" external USB devices. For many similar/such practical reasons, an IIAB microSD card (placed inside the Raspberry Pi) usually makes much more sense.

PRIVACY AND SECURITY WARNING: If you're booting from a USB device (e.g. an external disk or flash drive) please set usb_lib_enabled: False in /etc/iiab/local_vars.yml prior to installing IIAB, so that your filesystem is not viewable at http://box/usb. You can also do this after installing IIAB, using Admin Console (http://box.lan/admin) > Content > Services Enabled > USB based content libraries (uncheck the checkbox) > Save Configuration > Install Configured Options — give it 1-2 minutes and then verify that this completed in Utilities (menu) > Display Job Status — and finally reboot. (#2552)

How do I back up, shrink & copy IIAB microSD cards?

Privacy Practices for removing student/teacher personal data and protecting medical confidentiality will emerge at #1516 and/or Security.

IIAB communities around the world would LOVE your help making a 1-to-2 minute "Offline YouTube" (friendly screencast) outlining the best approach(es) below — and how to use them — please if you can, do consider making any such very short video!

1. Self-Clone your entire Internet-in-a-Box (IIAB) e.g. to an external microSD card, using IIAB's Admin Console http://box.lan/admin > Install Content > Clone IIAB (details).

• This approach works to copy to another brand/model of microSD card that happens to be a few bytes smaller!
• Copy from your IIAB's internal microSD to an external microSD (placed in a microSD card reader/writer, that plugs into one of your IIAB's USB ports).
• This is based on piclone_cmd (similar to rpi-clone) which brings the Raspberry Pi's "SD Card Copier" approach below (piclone) to the command-line, and other platforms and OS's (e.g. 64-bit Ubuntu not just 32-bit Raspberry Pi OS) (#2268).
• This approach can be slower than 3. and 4. (below) but is far easier to understand (and a real lifesaver in the field, when duplication hardware/peripherals/adapters are often scarce!)
• 2022-09-09 WARNING: PLEASE USE APPROACH 2. (BELOW) IF POSSIBLE — AS APPROACH 1. (ABOVE) OFTEN FAILS TO START PROPERLY WITHIN THE 1ST MINUTE (#3362).

2. Likewise a very easy/friendly approach is possible if you have access to the "Desktop" (graphical) version of Raspberry Pi OS. Simply click the Raspberry start menu (top-left of screen) > Accessories > SD Card Copier:

• This approach works to copy to another brand/model of microSD card that happens to be a few bytes smaller!
• Copy from the Raspberry Pi's internal microSD to an external microSD (placed in a microSD card reader/writer, that plugs into one of your Raspberry Pi's USB ports).
• You can also copy one external microSD card to another, if you have 2 microSD card readers/writers.
• Instructions:
  • Read its Help screen instructions. For a quick summary from the original May 13, 2016 announcement, see the "SD card copier" section which is the third headlined section in "The latest update to Raspberry Pi OS" (look below sections "Bluetooth" and "Bluetooth audio").
  • The underlying command is piclone.
  • This approach can be slower than 3. and 4. (below) but is far easier to understand (and a real lifesaver in the field, when duplication hardware/peripherals/adapters are often scarce!)

3. On Linux or macOS, we strongly recommend the built-in command dd if you are comfortable at the command-line.

• If you are copying to a different brand/model of microSD card that happens to be a few bytes smaller, 'dd' alone will fail!
• If so, you can solve this using the min-sd and cp-sd commands found here (min-sd is the underlying magic that shrinks or truncates microSD cards, without any data loss).

• Or consider PiShrink (README)
• Or consider shrink-backup (new in 2024!)
• Or consider rpi-clone by Bill Wilson. As of 2024, consider Jeff Geerling's fork ("A shell script to clone a booted disk on a Raspberry Pi") thanks to @framp.

• On macOS, 'dd' will run extremely slowly if you don't use macOS's own special syntax. So we recommend this macOS recipe, as an example:

• Insert a brand new microSD card
• Determine mount point of card: diskutil list
• Unmount card (this presumes its mount point is /dev/disk2): sudo diskutil unmountDisk /dev/disk2
• Copy source file (e.g. source.img) from Mac's disk to card: sudo dd if=source.img of=/dev/rdisk2 bs=4m status=progress

• Helpful Tip: The "r" device (e.g. /dev/rdisk2 NOT /etc/disk2) is the raw one. It should let you write 1 byte at a time, and is ~20X faster.
• Helpful Tip: If your macOS is older and status=progress doesn't work, you can type ctrl-T at the shell running dd to send it the INFO signal, to provide you a snapshot of how much has been transferred.

• Eject card: sudo diskutil eject /dev/disk2

4. Consider friendly software balenaEtcher for Windows, Mac and Linux — that should help you copy (clone) an entire IIAB microSD card to another.

• WARNING: Copying (cloning) WILL FAIL if the target card is a different brand/model, that happens to be even 1 byte smaller than the source card!

4.1 On Windows 10/11, strongly consider dotNet Disk Imager which is a "dotNet equivalent to Win32 Disk Imager, but more lightweight and with more features." [Several of us use this on Windows 8 and Windows 10, e.g. Tim Moody writes: "first time it stopped on the second partition after it asked me to format, like win32 imager...but it has a button to wipe the device and after I did that it completed"].

• If however you're copying to a different brand/model of microSD card that happens to be a few bytes smaller, consider minimizing/truncating IIAB's main ext4 partition using DiskGenius (formerly PartitionGuru) with these instructions:

• DiskGenius Professional software is $99.90 but it appears a Free Trial might also be available, while DiskGenius Free and their older PartitionGuru Free might possibly be missing the essential feature to shrink/minimize/truncate your ext4 partition?

4.2 On Windows 7 or Windows 8 (must be prior to Windows 10!) consider the "Read" button in Win32 Disk Imager to back up an IIAB microSD to your Windows hard disk:

• If you are copying to a different brand/model of microSD card that happens to be a few bytes smaller, this will fail! In which case try any of the alternate approaches listed above and below, or buy a larger microSD card.
• Before you begin the copy, specify a proper path and filename in the "Image File" textfield on top. We recommend you choose a filename ending with ".img"
• Copying from a microSD card will NOT work on Windows 10, which views the card as two drives, one of which Windows claims is not formatted (because it's Linux / ext4). It appears Win32 Disk Imager will however copy from microSD's on all versions of Windows up to and including Windows 8.1.

5. Is it possible Clonezilla can do part of this job? Clonezilla (unlike FileZilla) is free software for disk cloning, disk imaging, data recovery, and deployment.

How did IIAB/XSCE's design evolve?

Here's our brief-but-growing participatory design archive / lineage:

• Our earliest work is based on One Laptop Per Child's original XS design and implementation which arose in January 2007 to be used in many countries, thanks to John Watlington and Daniel Drake.
• Jerry Vonau greatly cleaned up XS(CE) networking, from approximately 2010 onwards, so that vital new hardware and networking topologies became possible.
• After the XS Community Edition grassroots team came together during the middle of 2012, using the XSCE name selected by George Hunt. Sridhar Dhanapalan wrote the Design Document in September 2012.
• Field implementer Tony Anderson expanded on these ideas laying out some Use Cases in October 2012, while many others contributed to a broadening roadmap of features.
• Internet-in-a-Box (also built by volunteer professionals, including Caltech and JPL software engineers) was founded separately by Braddock Gaskill in this same mid-2012 timeframe, in Southern California.
• David Farning's Activity Central team supported several developers to work on XSCE during the 2013 and 2014 timeframe, including Anish Mangal, Anna Schoolfield and others!
• German Ruiz at Fundación Zamora Terán expanded support for XSCE in Nicaragua, Columbia, Dominican Republic and Honduras (etc), as the natural successor to OLPC's original XS.
• The XSCE project embraced the Internet-in-a-Box name and IIAB's underlying OpenStreetMap work increasingly from 2013 onwards, until formally adopting the Internet-in-a-Box name (IIAB) in early 2017.
• Beginning in 2014, the XSCE project greatly increased its content collaboration with Internet-in-a-Box (hence our new name), with Kiwix.org, and with RACHEL (Remote Area Hotspot for Educational and Learning) — in each case greatly assisted by Tim Moody.
• George Hunt and Jerry Vonau made our critical transition to Raspberry Pi (and Ubuntu, and Debian) possible, with foundational OS/infra/networking work in 2016 permitting 2017's breakthrough into so many more communities. Enabling so many grassroots implementations that could never have afforded traditional PC-class servers and associated computer lab facilities/upkeep.

Community history is vital to all seeking to avoid reinventing mistakes of the past, thanks for Everyone's thoughtful input past & present!
