I changed the pyDECnet config to use this:

#
#   Circuit to Mark Matlock
#
#circuit DDCMP-30-1 DDCMP tcp:60001:rsx11m.com:7728 --t3=15 --cost=9
circuit MUL-30-1 Multinet --mode connect --remote-address rsx11m.com --remote-port 7728 --t3=15 --cost 20


Still not connecting. No error messages in the log file:

Mark is out running errands. I'll have to wait until he gets back to see what the log says on his side.

Thanks!

Hm. The command "MNC SET CIR IP-0-5 MODE DDCMP" should have given a warning that this has been deprecated. In essence, it does nothing.

All links are just multinet links, which is DDCMP, with a small header to just get whole packets when using TCP.

That explains the "MLTNET" in Marks error log.  So, if I set up the phDECnet circuit as a Multinet one is should work?

Yes.
