ABAKUS

Habe eben denselben Text bei WMW geschrieben, hier auch, falls jemand schnell reagieren möchte:

I today got some unfriendly visits by a MS bot:

207.46.141.155 - - [19/Sep/2004:10:24:14 +0200] "GET /dir-where-all-deepfiles-are-linked/ HTTP/1.1" 200 1900 - "-" "HTTP: User-Agent = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3" "-"
(Very professional!)
...

This one feeded the following:

207.155.199.163 - - [19/Sep/2004:10:30:05 +0200] "GET /deepfile.htm HTTP/1.0" 403 1286 - "-" "Mozilla/4.0 (compatible; MSIE 4.0; Windows NT; ....../1.0 )" "-"
65.164.129.91 - - [19/Sep/2004:10:30:12 +0200] "GET /deepfile2.htm HTTP/1.0" 403 1286 - "-" "Mozilla/4.0 (compatible; MSIE 4.0; Windows NT; ....../1.0 )" "-"
207.155.199.163 - - [19/Sep/2004:10:30:18 +0200] "GET /deepfile3.htm HTTP/1.0" 403 1286 - "-" "Mozilla/4.0 (compatible; MSIE 4.0; Windows NT; ....../1.0 )" "-"
65.164.129.91 - - [19/Sep/2004:10:30:26 +0200] "GET /deepfile4.htm HTTP/1.0" 403 1286 - "-" "Mozilla/4.0 (compatible; MSIE 4.0; Windows NT; ....../1.0 )" "-"

and so on. It definitely is a bot, as it does not seem to be impressed by a bunch of 403s.
Of course, no robots.txt was fetched, and the bot trap was hit.
