I'm making some progress. By using "setcap", not on my app but on mono itself, I get past the initial permission issue for the udp socket.
My app also accesses a library written in c which uses a socket to read canbus messages. On startup it tries a "ip link set blah blah..." This still responds with "RTNETLINK answers: Operation not permitted". I've tried setcap 'cap_net_bind_service=+ep' mylibrary.so but this does not seem to do the trick, even tho the library is called by my app which is itself started by mono. At this point I suppose this is no longer a mono question, just a Linux question, but if anyone has pointers I'd appreciate it.
