[PLUG] How to Block WEB Access for Certain IPs?

[Bill Thoen]

I'm trying to block a couple of overly busy Chinese web spiders from 
sniffing my site every hour, but not having much luck. I first tried 
putting this in /etc/hosts.deny:

ALL: 61.135.168.39,  220.181.32.22

but that didn't stop them. Then I tried putting this in 
/etc/http/conf/httpd.conf in the <Directory> tag:
    Order allow,deny
    Allow from all
    Deny from 61.135.168.39  220.181.32.22

and that didn't work. I restarted httpd each time I made a change. I'm 
using Fedora Core 9.

So how do you block a particular IP from accessing your web site? 
(without disturbing the firewall if possible.)
