No response from FreeRadius server

Hi, I have configured FreeRadius on Centos 5. It is configured properly and ready to process requests. I get following output in log file: Tue Sep 23 14:26:04 2008 : Info: Using deprecated naslist file. Support for this will go away soon. Tue Sep 23 14:26:04 2008 : Info: rlm_exec: Wait=yes but no output defined. Did you mean output=none? Tue Sep 23 14:26:04 2008 : Info: rlm_eap_tls: Loading the certificate file as a chain Tue Sep 23 14:26:04 2008 : Info: Ready to process requests. I don't get any response after I send Access-Request. What could be possible cause(s) for this? Thank you for help, Tomislav.
