Hi.. I'm working on a script that manages sharepoints on our fileservers. We have several fileservers throughout town, and my script is to run locally, and execute commands on a remote fileserver. Everything is Mac OS X. My eventual goal is to implement this over CGI on a secured website, but for now it runs at the prompt. I've tried 4 approaces, with mixed results:

1. $ssh_out = `ssh -2 $user\@$host $ssh_cmd`;
This gets complicated when running multiple commands (I have a few loops that generate a directory hierarchy). I also don't know how to send data to the stdin when prompted, so if my $ssh_cmd starts with a 'sudo', I have to type the password manually.

2. system "ssh -2","$user",'@',"$host","$ssh_cmd";
This gives me similar problems as above, as well as issues with my chgrp command, which must include a backslash as part of the group name.

3. using Net::SSH
I don't immediately see how to pass options to ssh itself, like the -2 or a -v. It also seems difficult, or at least expensive, to work this thru a loop.

4. using Net::SSH::Perl
Because this requires dozens of dependencies, I'm having great difficulty compiling and installing this under OS X.

What's the best way to open an SSH connection with a remote host and run a bunch of commands, some as the super-user, without asking for a password. I've already exchanged SSH keys so I can log in from the terminal without supplying a password (yes, it's insecure, i know).

Thanks

Disclaimer: I'm a self-taught sysadmin, and an even newer self-taught perl enthusiast; this is my first script using cpan modules. No formal training in CompSci or programming. Electronics is my thing.
