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.
