First thing, you can use the <code> tag to format your code for easier reading, and it also seems like you're not using 'use strict' and 'use warnings'. I highly recommend both.

That being said, I'd also recommend looking into the Net::SSH::Expect module. It (to me) seems easier to use than the vanilla Expect.pm. Below is a snippet of code that I've used with it:

        my $ssh = Net::SSH::Expect->new (
                host => "$serverlist[$host]",
                user => "$user",
                raw_pty => 1,
                restart_timeout_upon_receive => 1,
                timeout => 6,
                ssh_option => " -x",
        );

It makes for pretty easy communication with the remote server, with several functions to send and receive data. You can receive for X seconds, read one line at a time, etc.

According to the documentation on CPAN, you can use it with or without password authentication. In my environment, I have ssh keys distributed, so I've not used the password version, but the docs say it's available.
