[PLUG] computer lockups

[Clinton Ecker]

This is really weird...one of my machines would do this
every 1-2 days last week so I just pulled out another
machine to use as my router and its been doing fine. Weird..

Woops..I think i sent out a blank message.  I was going to mention that my
ip
masq system sometimes goes to sleep and refuses to wake up.  By 'goes to
sleep' I mean that I can't log in to it, be it by ssh, telnet, rlogin, ftp,
http, whatever.  However, it still replies to pings, and the masquerading
does not go down.  i.e. all the other computers on the network still have
access to the outside network.  At first I thought maybe the computer's
power
management was kicking in, but power management was turned off.  Any
thoughts?
