SSH/Firewall issue
I am a complete UNIX neophyte with the unenviable task of trying to pseudo manage two SUN boxes with an unknown past. I was not responsible for setting them up, anything that was done on them previously, and have no means of figuring out anything that was done to them. So far I have changed the IPs and enabled root access for SSH. I also changed the IP in /etc/hosts associated with one of them from its previous public IP to its current IP on the local (private) network. Otherwise I have done nothing.
The machines are named Sun1 and Sun2 and are both on the same network. Everything works fine on Sun1. I can ssh into it from anywhere. For Sun2, however, I can only ssh into it from a client that is on the same network but not from a client on another network. For now, the user has been ssh'ing into Sun1 and going from there to Sun2. This works but is awkward.
I first suspected a firewall was active on Sun2 but ipfstat shows nothing and there are no rules defined in /etc/ipf/ipf.conf. As far far as I can tell ipf is not even running anyway. Is there some way I can tell for sure if a firewall is running somewhere on Sun2? Is there some other ssh setting that would allow only LAN access? I also compared /etc/ssh/sshd_config between Sun1 and Sun2 and could not find any differences.
