Rishi, regarding question #4, I think "exit" would be an appropriate way to terminate the secure shell. You're telling the remote host you're exiting and it will close the connection?

Regarding your other questions: how different is Net::SSH::W32Perl? I just read about it on CPAN and it says it is a copy of Net::SSH::Perl from early 2002. Maybe it behaves differently? Have you tried to contact the author (Scott Scecina, as listed on the CPAN page)? You could try the same commands using Net::SSH::Perl and see if it fails too.

Hi Mark,

  Thanks for the reply. Can you tell me why I am unable
  capture the output of "ls -al" in $out. Also after executing
  ssh->cmd, the code is stucking and the control is not going
  to the next statement following $ssh->cmd. Can you explain
  what I need to do for the script to contrinue executing
  all the instructions.

Regards,
Rishi

I think what you are asking is how to trap errors and handle them without
the script terminating? I had the same problem with Net::SFTP which uses the
SSH module. My solution is described in a previous posting which can be
found in the archive.

You can process the @warnings array and take actions based on errors you
recognize. Retry and write failures to a log, etc.
