Hello,

My question may seem naive but I am new in this forum.

I set up a (very) small new website (mainly for tetsing purposes), and I am amazed by what is see in the log... Besides what look like normal get request, I have other ones which I do not understand. Can anyone give me a hint or, best, a lead...

Here are some examples:

1. what looks to me like a legitimate request
---------------------------------------------------87.244.176.229 - - [31/May/2006:15:40:13 +0200] "GET / HTTP/1.1" 304 0 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)"
87.244.176.229 - - [31/May/2006:15:40:13 +0200] "GET /bornival.jpg HTTP/1.1" 304 0 "http://www.bornival.be/" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)"
87.244.176.229 - - [31/May/2006:15:40:14 +0200] "GET /pwrabyss.gif HTTP/1.1" 304 0 "http://www.bornival.be/" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)"

2. What I do not undestand
-------------------------------
200.19.252.33 - - [25/May/2006:22:19:52 +0200] "GET //README HTTP/1.1" 404 403 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)"
200.19.252.33 - - [25/May/2006:22:19:52 +0200] "GET /horde//README HTTP/1.1" 404 403 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)"
200.19.252.33 - - [25/May/2006:22:19:53 +0200] "GET /horde2//README HTTP/1.1" 404 403 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)"
200.19.252.33 - - [25/May/2006:22:19:54 +0200] "GET /horde3//README HTTP/1.1" 404 403 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)"
200.19.252.33 - - [25/May/2006:22:19:55 +0200] "GET /horde-3.0.9//README HTTP/1.1" 404 403 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)"
200.19.252.33 - - [25/May/2006:22:19:56 +0200] "GET /Horde//README HTTP/1.1" 404 403 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)"

There is "horde..." on my website !

This is your every day log file right here. You cannot prevent people/machines
from sending weird requests to the server, but to let you in on a little secret, I
haven't ever had any security breaches on my server.

I've been getting attacks like these since the earlier days of Abyss and all of it
is normal behavior. I wish I could make it stop but I can't.

Use Abyss's Anti-Hacking feature if you're worried about these requests.

Sincerely, TRUSTAbyss

ptulkens,

These requests are sent to your server to try to attack the scripts on it. They try to profit from well known security breaches in old versions of popular scripts by sending them URLs that could affect their normal behavior (that's why it is important to always have the most up-to-date versions of scripts you're hosting on your web site).
