Having a problem with Decnet -set h ### fails, but set h/lat ### works

[Victor Mendham]

Wondering if anyone can point me in the right direction to fix a decnet issue.

When I go to my PCM server I can connect to the console of FRODO, but the svr is getting flooded with the following circuit up messageevery 10 mins, I have not been able to find a corresponding circuit down message.

%%%%%%%%%%% OPCOM 18-MAY-2005 12:56:06.78 %%%%%%%%%%%
12:52:40 Message from user DECNET on FRODO
12:52:40 DECnet event 4.10, circuit up
12:52:40 From node 5.762 (FRODO), 18-MAY-2005 12:56:06.76
12:52:41 Circuit UNA-0
So from PCM I can connect to the console of FRODO. I can not get to FRODO with the set host cmd, The server is protected by a password and it never seems to accept it. If I set host/lat FRODO, it works, I can enter the password, then get a login prompt.

set h/lat frodo
%LAT-S-CONNECTED, session to FRODO established
%LAT-I-TODISCON, type ^\ to disconnect the session

Once on the server I can perform a set h 0 without any issues. Other servers which use decnet can not see the server.

I suspect the network cable has become disconnected and have dispacted a hardware tech to check the physical connection. Any hints???

Note: On April 12, the server crashed and a network component on the system board was replaced on this 8650 running VMS 5.5-2, no TCPIP installed.

Victor,

If you can connect via LAT, it seems unlikely that the network cable has been disconnected, though if you have multiple network adapters, it's possible that LAT is running on more than one.

It sounds more like DECnet isn't starting properly. I'd recommend you do some basic network diagnosis. Assuming Phase IV DECnet, try:

$ MCR NCP SHOW EXEC
$ MCR NCP SHOW KNOWN LINES
$ MCR NCP SHOW KNOWN CIRC

and make sure everything that should be is in state ON.

If LAT protocol works fine but DECnet not, I think that problem is in DECnet configuration.
It is EXEC on state on (see that using NCP command NCP>SHO EXEC). If exec isn't on then you must configure and activate it.

The results of
$ MCR NCP SHOW KNOWN LINE COUNTER
$ MCR NCP SHOW KNOWN CIRC COUNTER

may indicate a problem or not with the interface used by DECnet.

Thanks for the replies, it turns out the circuit was in sync mode, The transceiver was replaced, the server rebooted and Decnet came up properly.

Thanks for all the help.
