Hi Eugene and Alex, Thanks for the information. One point to take this a little further. If I turn file sharing on, does this leave port 22 open so that I can SSH into my machine? Following on from this, aren't I leaving a nice big open door for hacker attacks via port 22? I do have a hardware firewall with Stateful Packet Inspection, so theoretically I should be fairly well protected, but this no doubt relies on me not leaving the doors open. What is the best tool to SSH with? I'm not particularly good with the terminal so something with a decent GUI would be best. cheers, Chris
