I read a year back that Neth could exist for ARM but it needs to be compiled. Has anyone done so?
I have a r5s with good specs, 4cpu and 4gb ram with m.2. I was wondering how one could compile this Neth for ARM? I really like the UI and I think it would be great to have it on arm boards. 
Not officially supported but it’s possible, see Switched to NethSecurity (on arm64)
Is there an update on Nethserver too? It would be great to throw in a Pi based NS server here and there…
Just found this topic.
Hi
It is actually not that difficult, the build system of Openwrt/Nethsecurity are setup so one can cross-compile the whole distibution. That being said, it’s nice to have a somewhat beefy computer / buildnode to build it, in the end you need to build the hole thing.
here are some clues how the build an custom image:
key to understand configuring a new target is running make menuconfig in the builder-container
./build-nethsec.sh bash
make menuconfig
In addition to what Mark pointed out, the whole repo is just a bunch of files that ease the compilation of our packages and override/patches the original ones, in the end we just automatize what documented in the OpenWRT wiki: Testing to determine if you are a bot!
While building the update to Nethsecurity 8.7.1 for my own nanopi r6s, also build the nanopi r5s target. Which takes about a minute after having build the r6s target because it’s the same package-arch and most likely the same rockchip kernel.
NOTE: this is a highly experimental proof of concept no warranties what so ever and I have no plans to maintain it in the future.
I recommend to build you own images if you plan to use it on a regular basis.
If it works you need to touch /etc/config/dpi after going through the first boot wizard in the web-UI.
(unfortunately the absence of /etc/config/dpi seems to be the flag to trigger the first-boot-wizard)
