The Question is:
After upgrading from DECnet Phase IV to DECnet/OSI I can't use the DCL
command sh net.
How can I get the information about active nodes on the network now ?
I know that I can convert the ncp sh active nodes command to ncl command,
but is there a way to get the information in the same way as with the sh net
command.
thank you.
The Answer is :
The reachable nodes information provided by SHOW NETWORK is only
available from DECnet Phase IV routers, and is not available from
non-routing nodes.
As for DECnet-Plus, this information is not generally collected and
maintained in OSI and IP network host systems, as it can quickly
overwhelm a system. Various census agents and related tools have
been available to gather and maintain this information.
There is no direct equivalent of NCP SHOW KNOWN NODES in NCL. This
task was trivial under DECnet Phase IV, as the node database was local
to DECnet. Now the information can be spread out through a variety of
name servers.
To find this information from your OSI router, you can try the
following:
to display the adjcent nodes on the particular routing circuit:
NCL> SHOW ROUTING CIRCUIT 'CIRCUIT NAME' ADJ * ALL STATUS
to display all nodes that are reachable in the area:
NCL> SHOW ROUTING DEST NODE * ALL
to display all reachable areas:
NCL> SHOW ROUTING DEST AREA ALL
The syntax on the particular router -- if not NCL -- will vary.
To look around within the DECnet-Plus DNS namespace and for the nodes
that are in the local node's cache, please see the sys$system:dsmdecdns
and decnet_register tools. If you are "merely" looking to diagnose
DECnet reachability, try the command sys$system:cdi$trace.
