if you want to have a secure connection (I suppose you want, if you access some account on the computer
so..) then you need SSH-connection, the SecureSHell (no, not hell, but shell). SSH uses port 22 by default, as far as I know, so open that. also, you need to start sshd on the computer you want to have access to, and if your distribution didn't create the ssh keys (rsa and dsa) then it probably asks you to do so. but at least RedHat 9 did create the needed keys during post-install configuration, so if you don't already have sshd running (check: if "ps -e | grep sshd" without quotes prints you a line of a sshd-process, you're ok - if you didn't get anything, it's not running) then you should start it; the way depends on what distribution you're using.
so, to make it short:
1) start sshd on the computer you want to have the console connection in (if it's running already, this will do no harm)
2) if it wasn't running, and does not start because the keypairs are not created, create them - refer to "man ssh" without quotes
3) make sure port 22 can be used
4) use putty to connect to your computer's ip via ssh (or any ssh-capable program)
