[comp.sys.mac.comm] TCP between macs?

Lee_Fyock.D62@qmgate.mitre.org (Lee Fyock) (10/30/90)

I've been playing around with MacTCP and the
XCMD example stack.  So far, I haven't been able
to get two macs to communicate with each other,
although I can open a connection to a vax.  The macs
are appletalked together, and the appletalk network
passes through a gatorbox to an ethernet backbone.

Shouldn't the IP datagrams pass through the gatorbox
and then to the other mac?

I'd appreciate any clues!

This is a bug in the GatorSystem software. 
Any version before 1.5X0 eats TCP/IP packets 
directed from one Mac to another *within the 
same AppleTalk zone*. I notified Cayman of 
this problem and they quickly fixed it and 
sent me the version with the bug fix. 
(Another recommendation for Cayman 
Tech Support!) You might wish to contact 
them (via E-mail: cindy@cayman.com) if you 
would like this fix.
