This morning my cable modem went out and it returned to service while I
was out of the room. When I returned I was greeted by fsck; I'm not sure
if this is related to networking somehow but I figured I'd report it
anyway. This computer has 3 nics, does bridging across two, and provides
nat to the third. Kernel is about as old as the uptime was. As usual,
any more info wanted, just ask.
