Blackstar is a linux box, ip .35 (I'll not type the first
three octets in this.) It has a modem and runs pppd.
Three users each have a pppd account. They have ip addresses of .38 .44 and .75.
When someone is dialing into the box, another machine on
my net will crash, or have network problems. If rebooted,
I will typically get a message such as:
A machine with hardware address of 00:00:0C:FB:B2:C0 claims
to be .222 Net interface disabled.
Where .222 is the address of the machine in question.
Ifconfig and arp don't show any sign of 222. I can't ping
222 when this is going on.
