Right, my example is just a sample code written to demonstrate my requirement.
I didnt notice January included in that array :(
And let me clarify my requirement, im looking for a minimal approach of reading my firewall log and make a report with DoS attacker's IP,Threat type, No. of attempts, and Last attempt date.
I need this report only twice a year.That is, from Jan 2010 - June 2010, Jul 2010 - Dec 2010, Jan 2011 - Jun 2011 so on ..
I would like to archive my log file after each period.
So i hope this approach will help me in acheiving my task.


Thanks very much for your support :)
