Security

I am using Tiger. Under the Firewall setting I have checked the option to Enable firewall log. Occasionally, my external HD starts up from sleep after being idle for a period of time (although I am not that concerned with this, as I think OSX spins it on). Written in the log is several lines of the following:

Jun 19 18:46:15 PowerBook ipfw: 12190 Deny TCP 197.166.1.2:2197 193.169.1.334:5001 in via en1

Not sure if it is some trying to access my system, or the system its self.
I changed the IP address for safety HE HE.

Seems as if someone tried to access your system. 197.x.x.x doesn't look like a local adress.

Some port sweep just hit your firewall. Nothing to be worried about.
