You've looked at IPC::Run on CPAN already?

Here is a simple script to create a ssh session to a remote host:

#!/bin/perl

use Expect;

#--- ENSURE TO HAVE SUFFICIENT COMMAND LINE ARGUMENTS ! ----------------------#
if ( $#ARGV != 2 ) {
  printf("USAGE: $0 <host> <user> <pw>\n");
  exit(-1);
}

$host = shift;
$user = shift;
$pw   = shift;

#--- CONFIGURATION -----------------------------------------------------------#
$cmd    = "ssh -l $user $host";
$prompt = "[Pp]assword";

#--- START SSH LOGIN SEQUENCE ! ----------------------------------------------#
$exp = new Expect();
$exp->raw_pty(1);  
$exp->spawn($cmd);

#--- LOGIN AND INTERACT ! ----------------------------------------------------#
$exp->expect(10000, [ $prompt => sub { $_[0]->send("$pw\n"); } ]);
$exp->interact();

Feel free to substitute ssh by whatever (e.g. telnet, etc.).
