[HECnet] 'rexec' or 'ssh <command>' over DECNET

[Sampsa Laine]

Well, the logs are transferred over DECNET to the main host that runs SSH (the others are too slow to run SSH).

But they are generated by a DCL script on the node from which they are extracted (basically, DCL scripts are run on KUHAVX and LABVAX which copy the exported logs to SOLAR5).

So I execute the log generation process (which tells KUHAVX + LABVAX to export their logs to SOLAR5) and then fetch them from SOLAR5.

I am aware of this - I am using this to pull some logs from a couple of boxes to another, all VMS.

Eh... Are the logs not accessible over DECnet? Seems like you might be going over the river to get the water...?

Ok. Note, however, that the solution you came up with now is not really generally usable in DECnet, but is rather VMS-specific. But on the other hand, more or less any solution will be rather specific...

Not sure that a batch submission is that much different from your network connection though. Neither is really similar to an ssh session, unless I'm missing something.

Guys,

I remember there's a clean / elegant way of telling another node to run a DCL script for me, but   have totally forgotten how to do it.

Basically, I have three nodes, A, B and C.

I've set up proxies for user FOO across all of them.

Now I want node A (as user FOO) to be able to tell node B and C to run a script on them, as user FOO.

How do I do this?

I notice that you figured out one way, which is to use network communication to a named task.
Another is to submit a batch job on another node. A third is (I seem to remember) the ability to just request a program to be run on a remote node, but that might some RSX specific thing. I can check in manuals if you want to know more, as my memory is fuzzy on the specifics.
