SSH to a HP-UX Server works Interactively but not via a script, batch, at from Windows

[Alzhy]

And it just times out with a syslog entry like so:

Aug 9 03:45:53 pluto sshd[397]: fatal: Timeout before authentication for 10.234.63.59
Aug 9 03:56:37 pluto sshd[5212]: fatal: Timeout before authentication for 10.234.63.63


Anyone have any ideas how/where to troubleshooot?

You need to set your ssh for password less authentication-exchange of public/private keys or with use of /etc/shosts and .shosts file.

Mos people would set it with exchange of public/private keys. Generate keys on windows and add it to authorized_keys file on hp-ux.

Hey;

You need to set up a public/private key pair then configure the account on the target system to use the public key.

If you've already done this, run the commands using "ssh -v" and show the resulting log output so we can see what's happening.

HTH;

What type of authentication method is being used for ineractive -vs- script/batch/at login? The ssh client on the windows side has the same env variables set as when you run it from the command shell, right?

In your batch job, culd you add -vvv and dump verbose output to a log file. It might help troubleshoot.

Keys are in place.. and are not prompting for passwords.

It's just that via apps, batch, at from Windows - ssh to UNIX just times out with the above syslog entry on the destination UNIX machine.

Interactive ssh works fine however.

what's the syntax being used in the script? You might try using the -i option and provide the full path to the sshkey and add the username as well. Agian, seeing the script's syntax for ssh and the 'ssh -vvv' debug output would help.

Thanks for the tip.. am asking them to do a verbose ssh execution.

I think the syntax is simply ssh unixhst "some command"..

They claim as well that the batch/app only works if the account first ssh interactively and logs off.

I think you may need to consider using cygwin if you are launching from the windows side. This will give you a script friendly environment on the windows side :).

This link has some good ssh info for cygwin. This should allow you to setup a cron that will execute whatever you want from a windows machine. http://pigtail.net/LRP/printsrv/cygwin-sshd.html
