Hi All

I have written a small script that would ideally login into a cisco router and run a command and display the output onto console but i have encountered with an error and not able to proceed further.

Initially i encountered with error as pattern match timed out.

Found an perl monk link where it was mentioned to add line "$session->print("\r"); # required to wakeup.".

After adding the above line i'm getting error as below even though username and password are correct

Error: login failed: access denied or bad username at core_switch.pl line 29

I'm suspecting its something related to prompt and delay in passing username and password, but not sure how to overcome that

Please post a sample code and point me in the right direction to avoid the error and connect Cisco device

Is there a way where whenever i execute this script, it should prompt me to input the username and password for switch

I would like to know both ways i.e. hard coding of username and password, and also when i execute the script it should prompt for username and password

My code

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

# Command line argument while executing the script

if ($#ARGV < 0)
{
        print "Please run the script with correct arguments\n\n";
        print "Usage Details:perl core_switch.pl <Device IP>\n";
        print "Ex: perl core_switch.pl 192.168.3.10\n";
        exit;
}

my $ip = $ARGV[0];
print "===============================================================
+============\n";
print "Device IP:$ip\n";

#Connecting to Cisco Device 
my $session = Net::Telnet::Cisco->new(Host => $ip, Dump_Log => "dump.l
+og");

$session->login('xxxxx','xxxxxxxxxx');


#Executing the commands

print "===============================================================
+============\n";
print "CPU process history\n";
my @process_history= $session->cmd('Show process cpu history');
print "@process_history\n";
print "===============================================================
+============\n";
$session->close;
