There are two ways to do this: use lcnet/lcnode to list all nodes that are currently alive, or list the ns_helper database (which may have old or missing information). Use /etc/lcnet to display the current networks ('man lcnet' for info on possible options): % /etc/lcnet First Network Hop Hops ======== ===== ==== 814E4402 -- local 814E4403 15AE0 1 814E4404 1A581 1 814E4405 207FC 1 814E4406 19C7A 1 and then use a series of commands like '/etc/lcnode -from 814E4403.15AE0' to list the nodes on the other networks. List the ns_helper database using the edns command ('man edns' for more info): % /etc/edns The default ns_helper is 814E4402.2204A <edns> ld big c521 ... <edns> ld -ia internet address name 814E4402.01A581 big 814E4403.024F1D c521 ... <edns> quit Paul Szabo szabo_p@maths.su.oz.au

Paul Szabo: > List the ns_helper database using the edns command ('man edns' for more info): Edns will give me the info I want -- but the darned thing is interactive so you can't give it command line arguments to run it from a script (as in 'edns -ld'). Well, sort of true. I just tried rerouting stdin: #!/bin/sh edns <<EOF ld q EOF and it works, but ugly. It also prints an extraneous header id line and a summary line at the bottom that would have to be filtered out. (But then, that's what Perl's for, right?) Whatever happened to the Unix approach of making tools to be used together? Dennis Cottel, dennis@NOSC.MIL, (619) 553-1645 Naval Ocean Systems Center, San Diego, CA 92152

About getting a listing from the ns_helper database:
I was looking at the help page for /com/ld and there is a -root
option described below:
-root Display the contents of the replicated root directory managed
by the naming server helper.
I any scripts where I need a complete list of the nodes on our net,
I use "foreach node (`/com/ld -root -c`)". We have Aegis loaded in
our configuration, so I'm not sure if Aegis' 'ld' is available if you
load strictly BSD or SYS5. It's a pretty basic command, it might be.
Hope this helps.
