I'm using
freeradius-1.0.1 in Debian; radiusclient-0.4.3 and ser-0.8.14 in RedHat-9.0.
I did all that you saw and continue the same error in my ser log.
Which is the error that you see at your log ?
I see in ser log this
ser[16812]: rc_send_server: no reply from RADIUS server host.mydomain.com:1812
but in tcpdump nothing.
1) Can you please send me your radiusclient.conf ? 2) Where and how did you run tcpdump ?
regards,
lucas
