Perl and Net::Telnet

I have written the following script to access one of my cisco 3524

use Net::Telnet ();
$t = new Net::Telnet (Timeout => 1, Errmode=>'die');
@lines = $t->cmd("who");
print @lines;

The script times out at the following line:

@lines = $t->cmd("who");

I get a "command timed-out at U:\PerlScripts\ line 7"

If i comment out the above line the script executes, I believe the
waitfor line works fine, my actual prompt is SBR-3524-1>


I have staired at this for hours, any help is appreciated. What am I
doing wrong.

Re: Perl and Net::Telnet

Hi Jeff:

I'm going to give you the most valuable Perl lesson I know: add the -w to generate warnings and use strict:


#!/usr/bin/perl -w

use strict;

use Net::Telnet ();
my $t = new Net::Telnet (Timeout => 5, Errmode=>'die');
$t->waitfor('/Password\: /i');
my @lines = $t->cmd("help");
print "Lines: ",@lines,"\n";

Note that with -w you will see that your \s is not a recognized pattern. I changed your "who" to "help" because the "who" command is not recoginized on a Catalyst 5500 although I assume "who" is a valid command on a 3524.

If it ain't broke, I can fix that.
