Hi Paul,

I made some progress and need help with the next step - connecting to pydecnet.

Current status is DECnet 1.3 is up on VAX/VMS 2.0, I can SET HOST to self, and have DMC11 XMA0 device up and a link to DECnet/Python configured.

There is no way to avoid a receive password that I can figure out, so I am using HELLOVAX as both receive and transmit pw:

CONFIGURATION DATABASE NODE PIPY

NODE NUMBER: 32
PASSWORD REMOTE RECEIVES DURING INITIALIZATION: HELLOVAX
PASSWORD REMOTE SENDS DURING INITIALIZATION: HELLOVAX
SECONDARY LOADER FILE:
TERTIARY LOADER FILE:
DOWNLINE LOAD FILE:
DEFAULT NON-PRIVILEGED USERID: GUEST
DEFAULT NON-PRIVILEGED ACCOUNT NAME:
DEFAULT PRIVILEGED USERID: SYSTEM
DEFAULT PRIVILEGED ACCOUNT NAME:
NSP CONNECT TIMEOUT CONSTANT 0 SECONDS
REMOTES SERVER NODE:
SERVERS LINE TO REMOTE:
REMOTES HOST NODE:

CONFIGURATION DATABASE LINE XMA0

DEVICE TYPE: DMC11
CONTROLLER NUMBER: 0
LINE NUMBER:0
LINE ADDRESS:0
ASSOCIATED NODE: PIPY
ASSOCIATED BUFFER SIZE: 192
NUMBER OF BUFFERS TO ALLOCATE: 6
CHARACTERISTICS: FULLDUPLEX
MOP TIMEOUT CONSTANT:  10 SECONDS

pydecnet .ini has:

circuit DDCMP-31-43 DDCMP tcp:31431:172.31.31.31:31430 --t3=15 --cost=4
node 31.43 XX --inbound-verification HELLOVAX --outbound-verification HELLOVAX

and I keep getting OPCOM messages on the VAX saying:

   Opcom, 03:17:09.56, NETACP       Accnt=
   Opcom, DECnet line XMA0: INIT message protocol error from address: 32, name:
PIPY

I must be very close to getting 31.43 (XX) in if Phase II is supported like you indicated ...

Anyway, advice for me please?

Best regards

Supratim

Uh... Do you have Phase V installed?

Hehe - It’s VAX VMS 2.0 running DECnet 1.3 which I think is phase II based on the gunkies post athttps://gunkies.org/wiki/Installing,_Configuring,_and_Testing_DECnet_V1.3_on_VMS_V2.0 <https://gunkies.org/wiki/Installing,_Configuring,_and_Testing_DECnet_V1.3_on_VMS_V2.0><https://gunkies.org/wiki/Installing,_Configuring,_and_Testing_DECnet_V1.3_on_VMS_V2.0 <https://gunkies.org/wiki/Installing,_Configuring,_and_Testing_DECnet_V1.3_on_VMS_V2.0>>

Oh! Wow. Other end of spectrum. I don't remember ever touching that. Earliest VMS I ever played with was 3.7, if I remember right. Also never used Phase II. Earliest was Phase III. Did Phase II even support more than 43 nodes? I guess I should check some. :-)

43?   The spec says Phase II node numbers are in the range 2 to 240, but they aren't actuallly used for anything.  So, in a sense, Phase II can handle any size network.  But it doesn't do routing except the limited "intercept" stuff.  Still, with PyDECnet intercept, a TOPS-20 V4 node can talk to any HECnet node.

43 since that was the node number Supriatim was trying to set.
According to Wikipedia, phase II only supported 32 nodes. But as I've never used it, I don't really know what to think.
