connection

I have two CentOS 5 servers running iptables and apf.

I am having issues connecting with ssh from server 1 to server 2. I can connect from server 1 to a third server and from that third server to both 1 and 2.

In all cases I am using the IP address and not a host name.

I have stopped iptables and apf on all servers and it doesn't seem to change anything.

What is the best way to debug this process?
