SSH Hangs

jim lake — Tue, 20 Nov 2007 15:54:40 GMT

Hi,

I'm using ssh to connect to anouther vms node and execute a .com file. The command that I am using is as follows

ssh xxx.xxx.xxx.xxx -o "batchmode yes" @sys$sysdevice:[users.frank]script.com;

after the script runs it just hangs. I attempted to add line that reads exit in the COM file that it's executing. This never helped.

Thanks

Does it still hang if you put
$ logout
at the end of the command procedure ?

You could make that
$ if f$mode() .eqs. "BATCH" then logout
but I have not yet checked what mode an SSH remote batchmode runs as, so you will probably need to amend it accordingly.

I have never needed to try this before, and I get:-
warning: Authentication failed.
Disconnected; no more authentication methods available (No further authentication methods available.).

I guess I need to setup proxies or something, no time now to read up on what's needed.

Locally, the SSH command hangs. Anything
after that doesn't matter. On the remote
side, it doesn't matter.

I'd suggest getting SSH to work
interactively, then worrying about the fancy
stuff. (After reading the instructions, if
it still fails, try "ssh -v [...]".)

NETWORK, same as without "batchmode yes".
This "batchmode" is unrelated to VMS BATCH
mode.

Returning to the real world, so far, I
haven't found anything to beat the "define
/user sys$command nl:" method already
suggested.
