Alan DeKok,
Unfortunately, I'm getting the same negative results when running the recommended initial radtest test "radtest test test localhost 0 testing123". The following is the output I get.
radclient: socket: cannot initialize udpfromto: Function not implemented
I'm not sure where to go from here. I'm still running with the default configuration.
You need to re-build the server without support for udpfromto.
I read up on udpfromto, and from what I can tell the openSUSE 11.1 (x64) package for v2.1.1 DOESN'T have udpfromto support compiled in. I believe this to be the case, because changing my radiusd.conf so that the server is only listening on a single IP, instead of the default of *, fixed my problem. radtest now gets a reply, and no longer issues an error. With this configuration, udpfromto isn't needed, so there is no more problem. Thanks for pointing me in the right direction. Will Spann
