[NTLUG:Discuss] port 22 "filtered"

[Jack Snodgrass]

what does /var/log/secure say? That is where sshd writes it's log info. 
maybe it will tell you why it's not answering. 

also... have you just tried to do a telnet server-name 22 and see if 
it answers. If you get the prompt 
Escape character is '^]'.
or  
Connection refused

That would be useful info.
