We recently acquired some Sun 50's and hooked them into our Ethernet
along with two VAX's running UNIX, one running VMS, and some Sun 120's
and a Sun 170. The 50's can communicate perfectly with any of the Suns,
but when you attempt to rlogin to the VAX, everything slows to a crawl.
The packets/sec drops by an order of magnitude and collisions rise.
According to the Sun people on the East Coast the VAX either "talks too
slowly for the Sun" or "tells the Sun to slow down and the Sun slows down
too much." (These are second hand quotes, unfortunately.) Neither of these
makes much sense, but something is definitely happening. Sun did claim that
it was a 'feature' and that nothing would be done about it. Seems to me
that they should do something about it if they want people to buy 50's.
Has anyone else had this problem, and if so, was there anything that could
be done? We have someone else calling around Sun trying to get real answers
from them as well, but we'd appreciate any advice/help that we can get.
Thanks much, in advance.
