[Serusers] no reply from radius server

Hi, I'm trying to startup my ser with radius authentication, however i encountered the same problem with this post: http://lists.iptel.org/pipermail/serusers/2005-January/014425.html. I really appreciate that someone could point me put the problelm. :-( authserver radiusserver, 3.4.5.6 acctserver radiusserver, 3.4.5.6 where radiusserver with ip 3.4.5.6 in /etc/hosts, and tcdump didn't show any traffic with destinated radius server ip or hostname rc_send_server: no reply from RADIUS server radiusserver:1812 --> and sometime, i can't get to see this message. and the server just startup with log below without any message followed by.
