Larsen, AKA K5DI Perfect, so you don't need ssh running on your box because there is no initiation of a connection to your box. The only exception would be if you wanted to copy files from their system to yours using scp. Then I believe you need sshd running on your box to allow the incoming secure cp. So shut down sshd (thus closing port 22). If you are using a router/gateway then I imagine you must have had to set up port forwarding on it for incoming port 22 traffic. You'll want to remove that as well (as suggested, layers of defense). Jacques B.
