I am new to this website. I would like to know if anyone can tell me what I should do to prevent someone from constantly pinging me. I am using a blue and white g3 mac. I have a cable internet connection. I have a firewall which has recently been alerting me that someone is attempting an intrusion. Most of the intrusions are coming from Canada. I live in the U.S. When I check the ip address of where the pings are coming from using showmyip.com it only provides the "last" point of origin.

I would like to know how I can prevent someone from constantly trying to intrude on my computer. It's annoying. Better yet, how can I find this person or people doing this ?

Your help is much appreciated.
