Decnet+ configuration

Joewee — Tue, 14 Dec 2010 08:15:29 GMT

Hi All,

This is on my test machines. I'm running two instances of freeAXP on my desktop machine, both of them configured to a loop back adapter and the two loop back adapters are bridged together.

Two machines TEST1 and JOSE. Both the machines are communicating to each other via TCP/IP but i want to make them to see each other through decnet.

I have registered the decnet address of both the machines on each other with

$ run sys$system:decnet_register.exe

This was working fine a week ago. I'm not able to find out where the problem is.

Please find the output below.

I find it strange that on TEST1 the current mac address is not set to AA-00-04-00-03-04

Can you do (on test1) a:

$ mc ncl show rout circ * enable phaseiv address

Oswald

Re: Decnet+ configuration

Joewee — Tue, 14 Dec 2010 11:23:55 GMT

Since im running 2 Instances of FreeAXP i have defined the mac address manually in the .cfg file as below.

pci11 = de500
{
adapter="FreeAXP";
mac="08-00-3b-aa-bb-cc";
}

Output:

Re: Decnet+ configuration

Oswald Knoppers_1 — Tue, 14 Dec 2010 11:29:26 GMT

It looks like DECnet did not startup properly. The MAC address should have been set to the AA address. Did you get any DECnet related error messages during startup?

Is the routing circuit started?

$ ncl sho routing circuit * all state

Hi,

Many thanks for your time on this.

Please find the output below.

Its on on one node and off on the other. I did not receive any error during the startup.

Rightnow I have added these two nodes in to a cluster.

Sorry about the time on the machine, I'm not able to renew my hobbyist license. Since my membership number is not getting updated for the past 2 weeks or so.

Startup log, attached.

Im not sure how to start this one...

I hope i've not messed up anything with decnet_register.

This is your problem. But I don't understand why the circuit wasn't started during startup.

Can you show the output of

$ mc ncl sho csma stat * all

You DECnet config is broken.

I would rerun sys$manager:net$configure and recreate the decnet configuration.

Re: Decnet+ configuration

Joewee — Tue, 14 Dec 2010 14:49:59 GMT

I have done the same and everything is fine now...

Many thanks for you time on this...

Re: Decnet+ configuration

Joewee — Tue, 14 Dec 2010 14:51:48 GMT

As Oswald suggested, the DECNET configuration was broken, reconfigured everything is fine..

Thanks again.
