Greetings all.

I'm somewhat of a newbie to Linux (most of my experience has been with SCO) so please bear with me. \

I've got a new server (RedHat Enterprise 5) that I initially set up in my office without any problem -
i.e. I could connect via ssh with a terminal emulator, no problem. My office, FWIW, uses the 192.168.0.xx class C IP addressing.

Before I shut down and moved the server I reset the server IP address and default gateway to what I thought would be correct for the network, thinking this would be a plug-it-in-and-go thing.

Today I moved the server to its offical home. The new site has a somewhat different network setup (class A 10.10.x.x.) and try as I might I could not connect via ssh (or telnet for that matter)
from any other computer in the network - even after completely disabling the firewall and enabling telnet. I could connect using ssh on the server itself (ssh -l myname 10.10.10.20) but from
any other pc on the network, no luck - the login just sat and eventually timed out. I did not receive a "connection refused" message.

I know the machine is on the network - I can see the other machines and ping them without any problem.

What I've done: I added the test pc's IP address to /etc/hosts.allow file. I've verified that the sshd daemon is running.
I've looked at the iptables listing & don't see any red flags, but the whole iptables thing is new to me, so I could be very, very wrong.

I'm sure I'm missing something stupid and/or blindingly obvious & hope that someone wiser that I can point it out..

Can you ping this server from the other computers on the network?
Are you sure there are no other computers with the same IP address?
Are all computers on the same subnet etc?
