[navin]

Hi,
i have posted message regarding the ssh secure shell problem few days ago. Actually i'm having a problem that i'm able to execute ssh as a client from commnad line from a hp box.But ssh is failing with permission denied ,public key ,passwd error when used within the script. Any workaround idea or fix?Strongly Appreciated.
Thanks

Do you setup paswordless ssh login to be able to use it from script - http://www.cvrti.utah.edu/~dustman/no-more-pw-ssh/

Thanks for the doc. But for couple of reasons i may wish to try the ssh with passwd.
Thanks anyway for the useful document.

There's not so many details in you problem description...

It could be a scripting error:
Do you try to pipe the password instead of sharing the public key?
- this will not work unless you're using a sophisticated script which send the password *after* you've received the prompt (otherwise the buffer will be cleared).
- it could be that you run with another username...
- always check environment when a script don't run properly as a cronjob.
- also make sure it is sh-posix or that you specify which kind of shell script

Assuming no script problem:
This could be a host lookup problem.
Quite common if you have multiple NIC's.

What is the hostname in the public key?
# cat ~/.ssh/id_rsa.pub

Is this the same user@hostname as you always will be resolved to on the remote host?

When you login and run the script manually, the script/communication is likely to use the same interface as you connected to.

Client -lan1-> Host:Script --ssh-lan1-> Host2
(no-pty)Host:Script --ssh-lan2-> Host2

If Host is resolved differently on Host2 depending on which interface it is using, it might be unable to verify the key.
