This all started with some annoying search hijacking.
Recently, though, that the number of really nasty domains had grown quite a bit; indeed, so much so that excellent antidote websites like http://www.pintumbler.org/Code/dnsbl had sprung up with canned solutions for doing blackholes via BIND, much as I had been doing with MaraDNS.
In a nutshell, here's how to use the same system, with local customizations:
1) Add the following lines to named.conf: include "/etc/namedb/blackhole/spywaredomains.zones"; include "/etc/namedb/blackhole/other.zones"; 2) Create the subdirectories /etc/namedb and /etc/namedb/blackhole 3) cd /etc/namedb/blackhole ; wget http://www.malwaredomains.com/files/spywaredomains.zones 4) Create the file other.zones.
Here's a sample other.zones suitable for FSU Computer Science.
