[Zope] Block IP address in Z-Server?

Hi, is it possible to ban an ip address from accessing Zope? (similar to Apache's "Deny from" directive). There are some idiots doing ridiculous amounts of spidering against my site and I want to block their IP's. If not does anyone know of an os-level way to block it? (I'm running linux) thanks a lot -Kevin __________________________________________________ Do You Yahoo!? Get email alerts & NEW webcam video instant messaging with Yahoo!
