I have a one month old Redhat install that becomes unreachable via VNC, SSH, Samba etc. after about a day of being up. I usually have a couple Bittorrents running on this machine and that's it. Is there anything else that could be running that's making it unstable?

Is this after being continiously up, or are you shutting down at night and getting a new IP from your ISP? Set your hostname if you are on DNS (be sure to set it for your NIC, too)...

it's after being up continuously, that's what's troubling. I can sit down and physically log in to the machine but I can't even ping it from outside anymore.

Is there something on your net that is trying to act as a domain controller? I am thinking a WIN2K server or some other fancy NT thing?

nope, it's just my XP laptop and this linux box. The only thing I regularly run is FTP or the java BT client Azureus. I thought maybe one of them was causing it, but like I said, I can still go log in to the actual machine, I just can't reach it from the network. Rebooting puts things back to normal. I guess I could try not running anything else on it for ahwile and see if the problem goes away to pinpoint it.

what do your log files reveal?

check /var/log/messages or /var/log/secure

are they registering communication attempts from your XP ip?

this is weird, I think the clock sync is screwing things up, that possible?
