Hi i was trying the suggestion you gave me and i have some problems or nubs questions ... here is what i have

use Net::Telnet::Cisco;

for ($i = 4; $i <= 10; $i++){
$device = "172.16.$i.251";

my $pe = $i;

my %users = ("6" =>"none", );
my %pwds = ("6" =>"thispass", );

my $curpwd = "admin";
if (defined $pwds{$i}) {
  $curpwd = $pwds{$i};
}
if ($users{$i} eq "none") {
  $session->login(Password => $curpwd);
} else {
  $session->login(Name => 'admin', Password => $curpwd, Input_log => "
+perllogrouter/router$i.log",);
}
   
 $session->cmd ("sh running-config | redirect ftp://172.25.1.101/proba
+$pe.txt");
   
  $session->close;
  }

and this is the error i get when i try to run this

C:\Users\mydesktop\Desktop\Perl>perl telnet.pl

Name "main::device" used only once: possible typo at telnet.pl line 5.

Use of uninitialized value within %users in string eq at telnet.pl line 16.

Can't call method "login" on an undefined value at telnet.pl line 19.

Any suggestion about this because im still learning the perl and some of the errors that i get im not quite sure what are telling me
