Re: SSH commands to HMC

Thanks to all for any advice.

Edward, the output from verbose mode is not very
helpful as you can see below (timeout).
The crazy thing is that an identical call 2 seconds
later works OK (below).
It is as if the 1st call fails, but somehow wakes up
the connection.

. etc until successful connection

I assume that ssh, ssl firewalls etc are OK since I do
actually get a success on subsequent calls.

What are the results of verbose mode:

ssh -v -l hscroot 10.26.10.21 date

or extra verbose mode:

ssh -v -v -l hscroot 10.26.10.21 date

Subject: SSH commands to HMC

All,

I am sending hmc commands to an HMC from a UNIX
command-line using ssh.
On the first call the connection times out (see
below).
On the subsequent call (immediately afterwards) it
connects and runs OK, as do any other iterations.
If I leave it a few minutes, I'm back to a timeout
and
then it continues OK.

root@node9>ssh -l hscroot 10.26.10.21 date
ssh: connect to host 10.56.0.224 port 22: Connection
timed out

root@node9>ssh -l hscroot 10.26.10.21 date
Sun Sep 10 00:20:58 BST 2006

This is hopeless for scripting.Anyone know what
causes
it ?
