]   remote station either).

]   box. This can get pretty annoying if I have to do it once or twice a
]   week.

I received a number of replies (including one from a person at ISC)
confirming that this is a known problem (sigh)... A few other folks
suggested a way to get TCP/IP back without rebooting though. My TCP/IP hung
again this morning (after behaving for 10 days). Here is what I ended up
doing.

	login as root on the console
	issue an 'init 1' to bring the system down to single user mode
	request an 'init 2' from the single user menu
	go to multiuser mode using ^D
	issue an 'init 3' as root after getting back to multi user mode

Everything should be ok at this point. If you require a 'route' and don't
have it in your startup files, you will need to issue the appropriate

	route add xxx.x.x.x yyy.y.y.y 1

command.

Of course, what we really need is a fixed TCP/IP 1.3 from ISC.
