Review: Turris Omnia, a FOSS wifi router, NAS and Server, based on a highly improved OpenWRT, with BTRFS! - SLRPNK
slrpnk.netI dont even know how to summarize that machine 😄 It is absolutely awesome.
Turris [https://www.turris.com] is a company by the czech TLD registrar CZ.NIC
[https://www.nic.cz/], which is ran as a nonprofit and invests a ton in open
source network software. ## The Origin This talk summarizes it well:
https://www.youtube.com/watch?v=cB5OG_V3aSE
[https://www.youtube.com/watch?v=cB5OG_V3aSE] They wanted to build a device to
analyze hacking attacks on the people in Czechia. The device should be as close
to the network as possible (i.e. a router) and have compelling and
understandable hardware that could be upgraded over time. So… they made a
router. Originally using PowerPC, now on ARMv7 (poorly only their mobile MOX
already is on ARMv8). ## Where to get it Originally they gave the devices away
for free, under the agreement that the users contributed the Sentinel analysis
data. Then they opened an indiegogo campain
[https://www.indiegogo.com/projects/turris-omnia-hi-performance-open-source-router#/],
which far exceeded their expected amount of funding. Afterwards they had their
own webshop [shop.turris.com], which is now discontinued. Instead, these stores
are available: - Rubytech DE [https://www.rubytech.de/turris-router/] (The
strangest signup method I ever had :) but all fine) - Discomp CZ
[https://www.discomp.cz/turris-omnia-wi-fi-6-silver_d116907.html?action=setcur&curid=14]
- Amazon
[https://www.amazon.com/-/de/stores/Turris/page/4EB82124-A160-4117-9404-00DA2DF8FE26]
Note: they sent me an additional Tshirt, ethernet cable and tube scarf, which
is… interesting, but could be considered waste. Tbh, I use the tube scarf daily
:D Poorly they didnt add any stickers! Also, they dont have a good system to
determine the recipient country, so I have an additional power supply cable for
another country. They also included a wall mount, with a set of perfectly
fitting, longer screws. All screws have regular phillips heads. ## Software They
took OpenWRT, but extended it a ton. As they have 8GB of storage and 2GB of RAM,
they can do stuff way above the minimum hardware requirements of OpenWRT. They
have a graphical package manager in the WebUI, and use BTRFS snapshots for
atomic updates. Which is totally cool! That was over 10 years ago and the first
router they made is still supported with updates. ## Hardware The data sheet can
be obtained here
[https://secure.nic.cz/files/Turris-web/Omnia/Omnia_wifi6_datasheet_EN.pdf]. The
“Omnia Wifi6” I got uses a bit outdated hardware, similar to my Thinkpad T430.
They will very likelybswitch to m.2 slots and ARMv8, so you may want to wait for
such a revised model. The current Omnia has 3 mini-PCIe Slots, 2 USB-3 ports and
a ton of pins accessible from the inside. Picture of a disassembled Omnia Router

The left one supports USB, and below you can plug in a SIM card and use an
3G/4G/5G card. With an additional package, this can be used to automatically
fallback to cell network, when the regular connection fails. - The middle one is
just mini-PCIe - The right one supports mSATA so with a simple adapter you can
use SATA SSDs for near-native speed. (I want to do that, but it may need an
additional power supply) Article picture of a mSATA to SATA adapter

of couse in the front it has fancy RGB LEDs. They are used as indicators for the
running state, and for the action you do by pressing the “Reset” button. In the
back it has 4 ethernet sockets, 1 WAN ethernet socket to connect to the
internet, one SFP socket for a fiber connection, a multi-purpose button and a
power socket. The button in combo with the LEDs is used for various things like
reboot, reset, update, update from local file, update from internet. ## Setup To
set it up, connect it to power and with one of the LAN (not WAN) sockets to a
Laptop, using ethernet. Right, before setup it doesnt open a wireless
connection! This was confusing for me but really make sense. In the browser
enter http://192.168.1.1 [http://192.168.1.1] and a very nice graphical WebUI
guides you through the setup. If you use it over LAN, accept the self-signed TLS
certificate in your browser, then HTTPS should work. ## Applications It runs a
highly extended variant of OpenWRT. There is a huge amount of software
[https://docs.turris.cz/basics/apps/librespeed]. It varies from preinstalled
installable through packages, from Foris WebUI integrated to advanced, requiring
the normal OpenWRT LuCI or requiring configuration through the terminal. An
incomplete and chaotic overview: - file server: SMB, DLNA, encrypted storage,
mdadm - Transmission bittorrent client - OpenVPN server & client - Wireguard
(advanced) - Nextcloud, Syncthing (both have acessible login pages from the main
WebUI) - Tor - Adblock - Dynamic firewall - haas: honeypot as a service (needs a
public forwarded IPv4 address) - Turris Sentinel: security data collection
service, analyze incoming threats (the use they originally intended) -
Librespeed: lightweight network speed test - support for LXC containers to run
your favourite Linux distro - schnapps to manipulate BTRFS snapshots - LAN
monitoring with PaKon and Morce NOTE: the data collection service “Sentinel” is
opt-in and disabled by default. ## DNS The DNS Server is not set, I used nic.cz
[http://nic.cz] with DNSSEC, other providers like Cloudflare and Quad9 are also
available, just like manual setup. DNSSEC works with a single button press,
without any issues! ## Configuration You can configure things with a config
file, that you insert over a USB stick. ## Storage You can plug in an external
drive (USB of course, but I want to try mSATA to SATA) and it formats it and
moves all data on there. It sets up different RAID systems, I dont know if
encryption is supported. So, you have over 7 different ways to host a fileserver
on there, up to a full instance of Nextcloud. This is crazy! ## Wifi Routing You
can open 2 Wifis (no idea how that works) and each can also have a separated
Guest network. Security: - By default, WPA3 with WPA2 fallback is used. I
changed it to WPA3-only, as WPA2 is vulnerable to attacks (see this video on how
to sniff passwords with Kali Linux, which requires a custom kernel driver
[https://www.youtube.com/watch?v=X49lIPHcurE]) - 2 Guest networks possible, I
highly recommend to use those for everyone apart from Admins - VLANs are also
supported, and need to be enabled. - Reminder: before first configuration, no
Wifi is enabled. There is no initial password set. - you can have different
passwords for the admin WebUI and ssh. The reach is great, but roughly equal to
the modern Fritzbox we already have, which only has a single, hidden antenna.
The time to connect to the Wifi is a bit longer than at the FritzBox. ##
Community & Support Their code is all hosted on the CZ.NIC Gitlab
[https://gitlab.nic.cz/turris]. The Turris team can be contacted via email and
they respond pretty quickly. The same contact is used for repairs. They also
have a Discourse Forum [forum.turris.cz] for a long time, where people can
exchange bugs, issues, software and hardware mods, adapters etc. ## Other fun
stuff The founder of Turris has a Blog [https://michal.hrusecky.net/]
I’ve got a question! Can I run a router on just any piece of hardware, say a pi? Or do routers need special hardware for low latency translation?
I thought the same.
I suppose they use stuff like real-time-kernels.
Depending on your needs, a typical wifi router would need
The software needs to run on there, being Linux based that should be absolutely no problem. But a RPi5 afaik still has no upstream Linux support, but it also way overpowered for that job.
I totally think about building my own router, but also enjoy the service of Turris, their advanced OS that requires these high specs, their package repo and custom OS features not present in upstream OpenWRT.
