I thought I’d put a note here about my project to resurrect luci-app-radius. I posted about this over in the OpenWRT forums, but if anyone is interested check out my project.
I haven’t tried compiling this specifically for Turris, but it’s just a LuCI app and there are no architecture requirements for it. I worked on getting going on OpenWRT v21.02.2, but again, I don’t believe there are many changes in this part of OpenWRT.
I’ll be testing it on my Omnia running 5.3.5 which is equivalent to OpenWRT 19.07 for most things.
