Sorry, but I didn't follow the whole thread complete. Maybe parts of this were
already asked...
• Can you check on the host kananga, if sshd is running and really listening on
port 22?
Can you (as root) on host kanaga, and send us the output:
lsof -P -i -n | grep ssh | grep root | grep LISTEN
Check especially, if ssh is listening for all hosts (indicated by an asterisk
'*')?
• Can you check, if there are no Firewall restrictions for Port 22 on host
kanaga:
Do as root:
iptables -L -n | grep dpt:22
• Check, if there are no Firewall restrictions regarding the host on host
kanaga for your host titan:
Do as root:
for i in `host titan | awk '{print $NF}'` ; do iptables -L -n | grep $i
; done
• Finally, if you didn't get the answer yet, check on host titan, what ssh is
really doing, with lots of more verbose messages:
ssh -vvv rprice@kananga date
Thanks.
Best regards,
Klaus.
