[cobalt-users] Strange requests & SQUID cache cleanup on Qube3

["Graphics 800" <graphics@xxxxxxxxxxxxxx>]

Hi all!

1. Every day my server is requested for non-existing page (default.ida).
Requests (approx. 200 per day) are sent from various IP addreses with
referer 1264 or "-".
Here is an example lines from "home-error"  and "home-access" files
13:24:20 2001] [error] [client 195.206.2.21] File does not exist:
/home/groups/home/web/default.ida

HTTP/1.0" 200 - "-" "-"

There are also strange requests (less frequent) made for "cmd.exe" file from
various IP:
[Sun Aug 26 00:32:42 2001] [error] [client 213.96.133.152] File does not
exist: /home/groups/home/web/scripts/..ų???Æ../winnt/system32/cmd.exe
[Sun Aug 26 00:32:44 2001] [error] [client 213.96.133.152] File does not
exist: /home/groups/home/web/scripts/..ü????Æ../winnt/system32/cmd.exe
[Sun Aug 26 00:32:46 2001] [error] [client 213.96.133.152] File does not
exist: /home/groups/home/web/scripts/root.exe /c+dir+C:\

Can someone explain me, what is a problem?
How much these requests (200-250 per day) enlarge my outgoing traffic? (I've
noticed significant outgoing traffic growth when these strange requests
appeared).


2. How can I cleanup Webcache caching files? Seems that they grows
constantly from time when I started Webcache and my cache.log file is full
with warning messages. Turning Webcache off and on don't resolve the
problem.
