Sorry, if I misunderstood the question. If you want to execute a perl script as CGI, you have to mention Happy-the-monks post. If you want to start a existing perl-script on your server, and you just want a simple frontend, you can do it using a CGI like this:

#!/usr/bin/perl

use strict;
use warnings;
use CGI;
use CGI::Carp qw ( fatalsToBrowser );

my $q = new CGI;
my $host = $q->param('host') || '';
if ($host =~ m/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/) {
  my $result = qx ( ping $host );
  print $q->header(),
          $q->start_html('ping IP'),
          $q->p($result),
          $q->end_html;
} else {
  die "No IP, no ping!\n";
}
exit();

Remember, to use -t for security reasons.

Some explanation:

it is a simple CGI, you can put it in your /usr/lib/cgi-bin or whereever the cgi-bin directory is on your system.

always validate users input using some regexes.

the above script dies unless the $host looks like an IP.

I use qx to call ping. pings output is assigned to $result. You can call your script this way, if you have the right to do so, else you should try using sudo on a Unix-like system.

I've to thank Happy-the-monk for some advice.
