in reply to Perl's Telnet vs. Expect Module

What are you doing on the remote server? If you are just running a non interactive program, then I would use Net::Telnet. If they are programs that need interactive responses, then Expect is probably what you want. I usually ssh to a server and run a command with a system() call.

I probably should clarify that, I create a command like,

my $cmd = q[ssh hostname -l foo 'ls bar']; die $! if system($cmd);

    Which also requires knowledge of setting up ssh with passwordless keys. Read up on .authorized_keys (authorized_keys2) and ssh-genkey for more information. That is, if it is to be unattended, and probably less secure.

    Basically, I was to "push" a set of scripts to a remote system, execute them, collect logs and move then back to my server, then clean up the remote server. So, script executed remotely is not interactive, but I need to do other actions pre/post executing the script.
