Hello.. I am new to this board and it has been some time since i have worked writing PERL. I have been asked to take a look at the attached script and see if I can get it changed from using TELNET to using SSH. I wonder if it is as simple as changing the module from NET::TELNET to NET::SSH. Any advice?

#!/usr/bin/perl
use Net::Telnet;
use strict;

#********************** User defined variables ***********************
+**************

my $username='adminuser';
my $password='xxxxxxxxx';
my $machine='192.168.102.21';

#*********************************************************************
+**************

#Open telnet session to host 
my $telnet = new Net::Telnet ( Timeout=>30, Errmode=>'die', Input_log 
+=> 'logs\\telnet-remove-exclusions-log-WLC02.txt');
$telnet->open($machine);
$telnet->waitfor('/User: $/i');
$telnet->print($username);
$telnet->waitfor('/Password:$/i');
$telnet->print($password);
$telnet->waitfor('/\(Cisco Controller\) >$/i');

#check for error status which should be undefined
my $msg = $telnet->errmsg;
print "$msg\n";

#loop while the command does not timeout looking for a different promp
+t
while (not $msg) {
  my @output = $telnet->cmd(String => 'show exclusionlist', Prompt => 
+'/Would you like to display the next 15 entries?/', errmode => 'retur
+n');
  $msg = $telnet->errmsg;
  $telnet->print('N');
  print @output;
  foreach my $mac (@output) {
   if ($mac =~ m/([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})\
+:([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})/) {
      my $cmd = "config exclusionlist delete " . $mac;
      $telnet->cmd(String => $cmd, Prompt => '/\(Cisco Controller\) >$
+/i');
   }
  }
}

#once command times out looking for the continue prompt, run it one mo
+re time with the regular prompt
my @output = $telnet->cmd(String => 'show exclusionlist', Prompt => '/
+\(Cisco Controller\) >$/i', errmode => 'return');
print @output;
foreach my $mac (@output) {
   if ($mac =~ m/([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})\
+:([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})\:([a-fA-F0-9]{2})/) {
      my $cmd = "config exclusionlist delete " . $mac;
      $telnet->cmd(String => $cmd, Prompt => '/\(Cisco Controller\) >$
+/i');
   }
}

$telnet->print('logout');

Any help on this is greatly appreciated!
