Whoever said that is confused and wrong. Sorry. You need to set up Multinet links.

I misunderstood. But figured because changing to Multinet on pyDECnet side did not make
any difference. Mark just gets a different error

Sortof yes, but no.
The errors are because RSX is receiving packets without that multinet header.
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? 10:45:36 MLTNET - IP-0-5 TCP ACCEPT failure. IOSB=-37
Oh, well. Time to fire up a local SimH RSX node and see if I can figure out what I'm
doing wrong.
Thanks!
What I meant with the above was this:
.mnc set cir ip-0-3 mode ddcmp
MODE have been deprecated.
Please update any configuration scripts.
.
You should have gotten those errors in RSX when doing the command. But yes, also, the
fact that you set your PyDECnet side to talk DDCMP caused the errors when receiving
packets.
Mark has it in his startup script I assume. It's probably been a while since that
system was booted so he my have forgotten or didn't notice.

Because that's what I was told needed to be done to connect to other HECnet nodes?
Mark has several set up that way and so does Supratim.
