Hmmm... strange. I never touched any proxy settings, but when I looked at
# Proxy Server directives. Uncomment the following lines to
# enable the proxy server:
I hope you're right, that it's not on by default. Then again, this would mean that my system has been compromised at some point.
Anyway, I did a google search of my IP, and it came up with a bunch of anonymous proxy lists, some of which still had my IP on them (even though I shut it down a week ago).
Also, since I've shut it down, my traffic has steadily decreased:
12/Nov/2004 : 15371
11/Nov/2004 : 20056
10/Nov/2004 : 25740
09/Nov/2004 : 37073
I estimate that Nov 5th, when I first saw a problem, I was serving well over 100,000 pages.
Thanks again for helping,
