Shell Programming and Scripting

try changing your cron to output stdout and stderr to a log:

for example

30 * * * * ssh -l user1 servername /path/to/script/scriptname > /tmp/sshcron 2>&1

What do you see in the output file?

Tried that - but nothing is logged to the file. The file is created but nothing errors to the file. The process appears to hang.. I left it for 10 mins then killed it. Then only thing that is written to the log file is:
Killed by signal 15

I think that the problem is it's waiting for you to type a password. I'm having this same issue, I can't figure out how to pass the password to it in a script.

This shouldnt be the issue as key authentication is in place and I can run the script from the command line without being asked for passwords..

Why should this make a difference from cron?

Can you change the ssh command line to include -v.

If that doesnt help try to truss the process.

I included the -v option - Again I had to kill the processes after 10 mins. I have pasted theoutput below. Can you see what is wrong?

Anyone able to help out here at all?
Any one see anything in the ssh debug that suggests why it wont run correctly?
