This machine is basically a name server and nothing much else at the moment.
It's usually runnning three logins via telnet over the ethernet interface, one
for me, one for root, and to receive log messages, there is not much else going
on there It's not even servicing many DNS requests, as the domain delegation
hasn't happened yet.

The messages from the last boot are duplicated below. Special things to note
about this machine are that it doesn't really have a serial console connected
to it, and that it doesn't really have a monitor on it (the "monitor" is just
some wires stuck in the monitor port to trigger the sense). The ethernet that
this machine lives on is _very_ large, (about 13 8 bit IP subnets, plus DECnet,
IPX and Appletalk traffic), and has lots of ethernet broadcast and multicast
traffic as a result. The ethernet card is of unknown ancestry, and is connected
to the apple NuBUS/FPU card (It's a IIsi). The machine also seems to hang after
about 4-5 days, but I can't tell what's going on, as I don't have a console for
it (I'm working on getting the cable right - if anyone knows how to wire an
MMJ-DIN serial cable for a DEC vt320, I'd love some advice).
