[comp.unix.ultrix] Ultrix promiscuous responses to LAT service requests

archerb@kuhub.cc.ukans.edu (05/09/91)

	I upgraded from Ultrix/UWS 4.0 to 4.1 last week (finally).  Since I
recieved a new system disk I installed from scratch.  I did however, copy over
my old 4.0 config files.  I got my disk partitions set, and everything went
fine - until the DECstation (5000/200) suddenly started responding to *EVERY*
LAT request.  The poor LAT clients, of course, got upset at getting two
responses to their request broadcast.  Terminal servers that had a circuit
open already were fine.  But if the circuit had to be established - my
DECstation tried to answer.  I rebooted and everything was fine for days -
until yesterday, when the same thing started happening again.
	Now, I had the DECstation set up to only offer a 'date' service
(as in the Ultrix DOC example).  That connected fine.  I couldn't see anything
weird going on the workstation.  TCP/IP on the network was going okay, also.
	I captured some frames with our sniffer, and I could see the terminal
server request go out, and the DECstation sending a response to BOTH the
terminal server and the service host.  I don't know LAT enough to understand
what on earth the DECstation was trying to do.  Rebooting again caused the
network to go back to normal.

	Any ideas as to what might be causing the DECstation to go LAT crazy?

Thanks,
