hosts.deny - get China off my server

[herbert langhans <herbert.raimund%langhans.com.pl@localhost>]

Hi List,
before I start these experiments I better ask you.

I have my NetBSD-server with a couple of websites on. Also two Wikis
(the well known Mediawiki) running. There are always couple of 'users' -
actually some bots or script kiddies what try to open an account there.
It is annoying to delete hundreds of these. There are plugins for
Mediawiki, but they still require care.

Since many of these requests are from China, I would like to block the
whole ip-range. This is possible by adding them to /etc/hosts.deny - but
maybe there are some better solutions.

A simple question: What do/would you use to get China off your server?

All ideas welcome. Thanks!
