That's fine. Apache on what?

Some OS's (like Linux or BSD) have firewalls as part of the default installation. You can set up a quickie firewall rule to block the IP address.

OpenBSD firewall example from my web server:

Code:

# cat /etc/pf.conf
# External interface and address
ext_if="vr0"
ext_ad="xx.xx.xx.xx/32"

# in general, block all incoming connections
block in on $ext_if

# block all net idiots
block in quick on $ext_if inet proto tcp from [badipaddr] port = 80

# let all outbound traffic go
pass out quick on $ext_if inet from ($ext_if) to any flags S/SA keep state

# let everyone else access the web server
pass in quick on $ext_if inet proto tcp from any to ($ext_if) port = 80 flags S/SA modulate state

I believe you can use your /etc/hosts.deny file to block access to your web server. As you can see, I use my firewall for that so I'd have to do a little search before I could present an example for you. Try googling on hosts.deny.

Oh and of course, don't use my pf.conf file without knowing what every rule does. I've clipped out a bunch of rules so I can show you a little example.
