Hello,

I tried to login to a router with a perl script. I opened a thread about this 2 days ago: http://www.perlmonks.org/?node_id=1126932

Here is the code for the script for logging into 1 router. This script works fine.

#!/usr/bin/perl --
use strict;
use warnings;
use WWW::Mechanize 1.73;
my $browser = WWW::Mechanize->new( autocheck => 1 );
$browser -> agent("Mozilla/5.0");
$browser -> credentials('192.168.1.1:80','TEL','admin' => 'guess');
$browser -> timeout(10);
$browser->show_progress( 1 );
$browser->get('http://192.168.1.1:80');
if( $browser->success ){
   die " we logged in game over";
}

Now i have some problems if i modify the script for logging into 3 routers. I made a text file with the 3 IP's of the routers i want to login. The perl script is reading the IP's from the text file and fills the 3 IP's as strings in an array. I use a for loop for looping through the array and to setup a connection with the 3 routers. I have a 401 Authentication error when i run the script. 

#!/usr/bin/perl 
use strict;
use warnings;
use WWW::Mechanize 1.73;
my $file = "output.txt";
open (FH, "< $file") or die "Can't open $file for read: $!";
my @lines;
while (<FH>) {
    push (@lines, $_);
}
close FH or die "Cannot close $file: $!";

my $browser = WWW::Mechanize->new( autocheck => 1 );
$browser -> agent("Mozilla/5.0");
$browser -> timeout(10);
$browser -> show_progress( 1 );
for (my $i=0; $i <= @lines; $i++) {
my $url = "$lines[$i]";
$browser -> credentials("$url",'TEL','admin' => 'guess');
$browser->get("http://$url");
if( $browser->success ){
                print "login to $url was successfull!!";
        }
}

Contect of textfile (output.txt):
192.168.1.1:80
192.168.2.1:80
192.168.3.1:80

This is the error message: ** GET http://192.168.1.1:80 ==> 401 Unauthorized Error GETing http://192.168.1.1:80: Unauthorized at routerlogin.pl line 21.

For some reason there is a problem when using variable $url in $browser -> credentials and $browser->get. I tried lots of things but can't figure it out. anyone a suggestion?
