What is en0, en1?
I don't have the background to understand what the interface designations en0 and en1 are referring to. My concern is that my hard drive just went through about 2-3 minutes of activity. Don't know if it was normal housecleaning going on but found a system log file with several of these messages (Mar 16 22:28:18 p****-a***-power-mac-g5 ipfw: 35000 Deny UDP {IP Address}2190 {IP Address}:2190 in via en0). Am I to interpret someone was trying to enter my system or has entered my system? Advice on where to go to learn and figure this out will be appreciated. Thanks!
