Well I have 3 computers right now 2 of them running redhat 9 and one running mandrake 9.1. I have the gateway to the internet going through the mandrake 9.1 machine. I am interested in how I can ssh into one of the other computers or I have heard about remote X query and such. Does anyone know a way to do this or something similar? I mainly just want to get on one machine from another. Everytime I try just a simple ssh command it says connection refused or something like host not found. I am not sure whats the deal. Thanks everyone

you must see whether your have installed ssh on your system using command rpm -qa | grep 'ssh' if not installed get it first and install. then you can using it.

and the ssh service should be active too...
on RH do a
#setup
and go to the services submenu, look for ssh

If there is no ssh then you don't have it installed
If exists then it must be checked so that you can have an active ssh server

I don't do mandy, so I can't tell anything about that...

Is SSH on the remote machine accepting connections?
if so is it asking or does it need a private_key?(RSA/DSA) or other type
check the /etc/ssh/ssh_config and /etc/ssh/sshd_config to make sure that you have the correct settings.
