After looking at my ssh disconnection problem I'm still at a loss for why it's occcuring. However, I did get some error msgs that are popping up on the terminal which might prove to be useful to help diagnose my situation. (For a refresher, my problem is that my remote SSH connections to my box disconnect at arbitrary times and for a varying amount of time I can't reconnect.) When disconnection occurs, I'm getting this on the terminal of the machine I'm remotely connecting to: sshd[79987]: fatal: Write failed: Permission Denied (i get this repeated a few times) natd: Failed to write back packet (Permission Denied).
