Then as I said before: show the corresponding logs in the server logfile -
or report that there are none.

Also check if there are any errors logged at the client side (e.g. in
/var/log/messages or /var/log/syslog)

Next test: capture the RADIUS packets on either client of server:

    tcpdump -i eth0 -nnv -s0 udp port 1812

(assuming 'eth0' is the interface the packets are going in and out on)

Are you getting any packets sent at all? If you are, are you getting a
respose from the server? If so, what is it?

If no packets are being sent, another useful test is to run the client under
strace:

    strace -f ./radexample 2>strace.log

This may show you if a particular system call is falling (open, send, recv
etc)
