Hi,
The very last line of startup output will say
Ready to process requests
If you get NOTHING else then the server is not getting any packets through to it...which is either something simple such as the built in firewall of cents (edit the firewall using your favourite method to allow UDP 1812 through for RADIUS auth packets), a network
issue, (routing, ACLs etc) or a switch configuration issue.
