While I'm away from my network on the weekend, I like to know what's going on. I downloaded the program Snort and it keeps a log of the different goings on. I could VPN to the network, and just look around, but it's more convenient if I let perl send me the the last 25 lines of my log file to my email account at home. Here is how I did it.
use strict;
use Net::SMTP;
print"monitoring snort log \n";
print " hit q then enter to exit:  ";
open (fh, "< e:\\snort\\log\\alert.ids") or die "Can't open File";
my @lines = <fh>;
my $hours = 0;
while (<STDIN> != 'q') {
   while ($hours < 72) {     # hours of updates you want
      my $timer = 0;
      while ($timer < 1) {  # minutes between the update
         #Mail Data
         my $smtp = Net::SMTP -> new('mailserver.mail.com'); #Connect 
+to a mail server
         $smtp -> mail( 'sending\@mail.com'); #Sender's name
         $smtp -> to('receiving\@mail.com'); #Receivers name
         $smtp -> data();
         # Send the header
         $smtp -> datasend("To:  'receiving\@mail.com\n");
         $smtp -> datasend("From:  sending\@mail..com\n");
         # Send the Body
         my $x = 0;
         while ($x < 25 ) { #lines to print
            my $lines = pop @lines;
            $x++;
            print $lines."\n";
            $smtp -> datasend($lines);
         }
         $smtp -> dataend();
         $smtp -> quit;
         $timer++;
         $hours++;
         sleep 3600;
      }
   }
}
close (fh);

I would appreciate a review of this code, I want to make it better. BTW This is a Win32 version, I'm working on a linux version as well.
Many thanks,
