Just got this from Tim@Mjorgeeks.com If your like me you run firewall software that tells you when someone tries to access your system. Sometimes I respond with a few packets of my own just to let them know that I am paying attention. I wrote Slap to make responding to these access attempts easier and more entertaining. Just enter the IP address of the person you wish to slap and click on the Slap button. The program will attempt to access all the ports in the list and send them a packet with a personal message. (The default message is 'Leave Me Alone!') Slap integrates with Black Ice and Zone Alarm! Did I mention it's Free. Download Slap 1.1.1.6
