[net.lan] Ethernet problem with SUN-50 and DEUNA.

jaap@mcvax.UUCP (Jaap Akkerhuis) (05/16/85)

On our local net we have the next different machines sharing one
Ethernet cable:

VaxA	Interlan Ethernet controller (NP1010) with np10 transceiver
VaxB	3-Com controller and transceiver
VaxC	DEUNA controller H-4000 transceiver
SUN170	SUN disk server, 3-Com controller and transceiver
SUN120	Diskless workstation, 3-Com controller and transceiver
SUN50	Diskless workstation, SUN controller and 3-Com transveiver

The vaxes run 4.2BSD, and the sun's SUN 4.2BSD release 1.3

The Sun's boot via the net, it is possible to do rlogins from all the
vaxes to each other, from the sun's with each others, from the
sun's to the vaxes, and from the vaxes to the sun's, with one
exeption:
	It is not possible to do an rlogin from VaxC to the SUN50 or
	the other way around.
If we replace the DEUNA and H4000 with a spare Interlan controller, it
is possible rlogin with the SUN50. So to me it doesn't look like a
software problem.

This is the question: Why can the SUN50 not cope with the DEUNA?
Has anybody a similar experience with this and maybe a possible fix?

Send your remarks by mail to me (mcvax!jaap) and I'll summarize to the
net.
