What's up with your DECnet installation, again?

It's connected to the network, yet it can't reach any other nodes. Adjacency notices between nodes are seen, but they cannot communicate. 

Alpha to RSTS/E resulted in

And VAX to RSTS/E just results in a timeout. Attempting to dir from an Alpha results in the request being seen on RSTS/E, but it fails.

RSTS/E to Alpha results in 

$ set host 33.302
Connection Established to VAX/VMS Node 33.302

?Unsupported Virtual Terminal Protocol.

Control returned to node MINDY

So, I don't know what I misconfigured.

Ok.   I'll bring up a RSTS/E system and run some tests here.   This will
involve real hardware; none of my emulated systems are networked right
now.   I may get to this later tonight.

You have a lot of real DEC hardware, don't you? ;)

As that could take some time, have any experience with DECnet and TOPS-20 in klh10? I read the documentation for it but it wasn't particularly helpful with regards to the networking "fronted" klh10 emulates, and I can't exactly load the executor config stuff to bring the node and circuit online.


Two things I can tell you is that I can easily reach a RSTS/E system
from a Linux system via LAT, and also file operations work between that
pair.   File operations also work between the RSTS/E system and an Alpha
running VMS. (all real hardware)

I've probably misconfigured something obvious.
