channel blocking

gopalreddy has asked for the wisdom of the Perl Monks concerning the following question:

I have a perl script to connect to remote host using SSH2 and execte commands. Script creates connection, opens channel, executes the commands and closed channel and connection. This script is called by some scheduler process which wil execute at 30 sec interval. it is working fine, but has script doesn't execute the commands when the remote SSH is reset(down and up). It works fine when i restart the scheduler. Can any one help?

Howdy gopalreddy, welcome to the Monastery! We'll need some more information to be able to help you. In particular, what problem are you experiencing? ("some tough time" could mean anything.) Also, what do you expect the script to do? If the remote SSH host goes down, then naturally your SSH connection will go down as well. Here's some helpful nodes on how to ask question: On asking for help How do I post a question effectively? How do I compose an effective node title? I know what I mean. Why don't you?

AppleFritter is right in saying that your initial writeup is a bit sparse, but I'm going to take a stab: Check the timeout setting on whatever SSH module you're using. I'll bet it's longer than 30 seconds. If the server barfs, the connection won't drop until that timeout is hit.	[reply]
