I come home from work today and my powerbook fan is on.... sorta odd since it's been doing nothing all day except checking my e-mail via Mail.app. I check top in terminal and here is what I get... any ideas? I vaguely know what natd does and I'm pretty certain that is really abnormal. My current uptime is almost 16 days. All sharing is turned off. My OS X Firewall is off but there is an airport base station I'm using as a router.
