Blocking whois and dnsstuff

[1EightT]

I would like to block both dnsstuff.com and #*$! from my server, but i'm running into a wall actually doing it. So far i've tried the following:

This is in my hosts.deny on my server:

ALL: .xyz, .xyz, .dnsstuff.com, .xyz

This is in my httpd.conf for the directory in question:

RewriteCond %{HTTP_USER_AGENT} ^whois [OR]
RewriteCond %{HTTP_USER_AGENT} ^dnsstuff [OR]
RewriteRule /*$ http://www.spam.com [L,R]

RewriteCond %{HTTP_REFERER} whois\.sc [NC]
RewriteCond %{HTTP_REFERER} dnsstuff\.com [NC]
RewriteRule .* - [F]

What the heck am I doing wrong here?

The forum screwed up the formatting on the hosts.deny code. Sorry about that.

Whether there is a 'problem' with this code depends on what exactly you're expecting it to do. So what were your test results and how did they differ from your requirements and expectations?

Are you trying to block clients referred from these domains, or trying to block accesses by servers at those domains?
