http://www.avanthar.com:8080/nodes/ seems to not be working to list currently active HECnet nodes. Assuming you have a VMS, RSX or RSTS system AND your node is a routing node (and your local node database is up to date), you can do NCP SHOW ACTIVE NODES to see the nodes that are adjacent to you. You can also do NCP SHOW KNOWN NODES to see the up/down (reachable or unreachable) status of every node. Unfortunately if your node is NOT a routing node then this won't tell you anything useful. BUT, don't despair - in that case you can ask your favorite routing node to tell you. On your machine you can say - NCP TELL LEGATO SHOW KNOWN NODES and this will actually send the command from your node to NML ("Network Management Listener") on LEGATO to be executed. You'll see the nodes that LEGATO thinks are currently up. This will work on any target node where the owner has been kind enough to enable the default DECnet account, e.g. MIM, and probably most others too. Bob
