Subject RE: Your Nutch Crawler is Out of Control - Apache Notified
Date Sat, 01 Oct 2005 03:35:29 GMT
All The Best!!!
I am not a Nutch Developer... I think I found a bug in Nutch's "Robot"
implementation... Also, today I found a bug in their HTTP
implmentation... But I don't have any time to re-test, and, probably, to
add some code!
Good luck,
Fuad

Importance: Low



Thank you for your email.

>>> http://lucene.apache.org/nutch/bot.html;
>>> nutch-agent@lucene.apache.org)" 128.95.1.189

The Canadian was, for some unknown reason, the first to respond to this
complaint. Although it appears from our research there was a Canadian
contingency that assisted in the development of an earlier version of
the Nutch Crawler at UW. Regardless, this has nothing to do with the
Canadian's IP.

The very first post indicated the offending IP is in fact owned by the
University of Washington, as is referenced above. Who, by the way has
completely denied the error in their ways and is in fact alluding to the
fact the only reason Their crawler spent so much time at Our server was
due to OUR server configuration. Completely LAME UW, not the way to
handle this issue. The Ducks are trying to DUCK the issues here.

We suppose, because they feel they are a University, with virtually
unlimited bandwidth, they are allowed to swamp people's servers with
anything they want and anytime they desire.

We are disgusted an academic institution, a place of higher learning,
the source of education and ethics for young impressionable minds, would
attempt to pass-the-buck like this. Especially UW.

The facts are as follows...

1) 202 sessions on our main server since the 18th of this month.

2) 328 minutes and 08 seconds of crawl time from 128.95.1.189
turingc.cs.washington.edu since the 18th of this month.

3) Indeed this crawler is ignoring our robots.txt file, go have a look
at our file for yourself. It was installed the same day we noticed your
abusive crawler hitting our site with 30X the bandwidth and regularity
of all the Google bots combined. Despite the robots.txt file being in
place, your crawler continued to scan our server with obvious and
continuing disregard for the implemented robots.txt file. 

This is the Internet, and while people are free to do as they please
without harming others, this is NOT UW's friggin' playground. And
someone at UW should step-up and say, Sorry, instead trying to
pass-the-buck like some two-year old.

We expect nothing less than an apology from UW.

Best Regards,

Web Experts America
