1. Report of Hacking Attacks Subject: Firewall Date: Fri, 28 Apr 2000 15:21:29 -0500 From: David Walsh To: zlin@ba.ttu.edu Dr. Lin, I recently had ADSL installed at my house. I have just downloaded a firewall to protect it, and I keep getting alerts every minute or so from something, or someone trying to access my computer. The IP address is 208.24.37.50, but it does not show up in the browser. I just get the standard error message. Is there any other way to find out what that site is? Thanks, David Walsh
