Re: Server Attack

I was actually thinking about that but arn't all those IPs spoofed? Could an innocent user have that IP address? Is it possible that he is randomly generating those IPs or is that impossible. Also most of those IPs are telecom servers.

We are currently blocking this user through our Apache.

.htaccess
[CODE]
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ $Macintosh;\ (.+)\ PPC\ Mac\ OS\ X;\ en-US$\ AppleWebKit/(.+)\ $KHTML,\ like\ Geco,\ Safari$\ OmniWeb/v([0-9]+).([0-9]+)(.+)$
RewriteRule .* - [F]
[/CODE]

That works fine and is giving the user a 403 (Forbidden), but the problem is that half of our Apache processes are from this user.

Is there a way to block his user agent before he gets to Apache? Sometimes this brings our server to a crash.

Thanks
Andrew
