[uk.general] CMU IP/TCP V6.3 problem: uVAX <-> HP <-> HLH Orion

keith@mva.cs.liv.ac.uk (10/03/88)

We have quite a major problem in getting HP 9000/300 equipment to talk
TCP/IP with a microVAX II running VMS V4.7 and CMU IP/TCP V6.3 over
ethernet.

Basically, FTP and TELNET connections don't seem to last very long - the
microVAX aborts with TCP Receive errors. Worse still, using PING on the HP
system to ping to the vax with packet sizes in excess of 800 (or so) characters
causes the IP_ACP on the microVAX to completely abort with an access violation. 

We have absolutely no problem communicating with an HLH Orion as long as IP
trailers are turned off and the Orion communicates quite happily with the HP
system. 

As the the HP system doesn't appear to support IP trailers, we assume that
there is a resource problem. Should something in INTERNET.CONFIG be tweaked?
The documentation isn't very helpful. Any assistance would be very welcome...
