supriyas has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am completely new to perl and need to write a script which will login to a router and execute few commands. Below is my code and I am getting a error as "Can't find @INC Net::SSH::Perl" I have also tried with Net::SSH and getting the same error. I have tried installing it all the ways but failed. Don't even know where I am going wrong. Please help.

#!/usr/bin/perl -w
use strict;
use lib qw("/path/to/module/");

use Net::SSH::Perl;

my $hostname = "hostname";
my $username = "username";
my $password = "password";

my $cmd = shift;

my $ssh = Net::SSH::Perl->new("$hostname", debug=>0);
$ssh->login("$username","$password");
my ($stdout,$stderr,$exit) = $ssh->cmd("$cmd");
print $stdout;

    What is "all the ways" you tried to install it? Post your command lines and their respective output.
    Also consider checking where you installed it to versus what your @INC is.

    Make sure you read the documentation for ALL the modules you use. For convenience, here are links to them: Net::SSH(::Perl) and lib. Consider also use warnings.
    Module example scripts are also very handy. With most modules, you can find them in the distribution.

      1. I opened command promt and executed "cpan install Net::SSH::Perl" and got the following error.

      2.and just gave "Cpan" so that it will enter to the capn promt where i can give "install Net::SSH::Perl" but giving Cpan alone is opening the capn GUI.

      3. Got a Net::SSH::Perl pm file and saved it in perl/lib/Net but didn't work

        Your network connection is broken. Maybe you need to go through a proxy server. Consider setting $ENV{HTTP_PROXY} to the appropriate values.

    It looks like you haven't installed the module. Try something like sudo cpan Net::SSH. You might want to update your install of ssh first to latest version.
