Hello, Can I specify an IP address of the radius server in radiusclient.conf, as opposed to a host name ? When I specify an IP address, I get the following error message: Oct 5 16:38:55 sipproxy ser[2115]: rc_ip_hostname: couldn't look up host by addr: D5F13A8C Oct 5 16:38:55 sipproxy ser[2115]: rc_send_server: no reply from RADIUS server unknown:1812 Oct 5 16:39:01 sipproxy ser[2112]: rc_ip_hostname: couldn't look up host by addr: D5F13A8C Oct 5 16:39:01 sipproxy ser[2112]: rc_send_server: no reply from RADIUS server unknown:1812 Why does the radius client try and resolve the host name for the radius server. Isn't IP address enough ?

I have run out of ideas and am starting to get a bit frustrated. I was wondering whether someone could help me out. I am using: SER 8.14 from CVS Radiusclient ng 0.4.2 (tried 0.4.3 as well) I have radiusclient.conf and servers configured. I get the following error in messages: rc_send_server: no reply from RADIUS server . I have run tcpdump to verify but it doesent show any attempts to contact the radius server. Any ideas ? Thanks, Dawid
