[NTLUG:Discuss] Domain Hijacking / interception / filtering /redirection

[brad angelcyk]

You could set up a DNS server on a linux server and
point all of the Win32 workstations through it.  That
way if you set up a DNS entry for something, it should
override the root servers.  I used to work at an ISP
and we would throw lan parties inside of our
storefront.  We did this to block websites that
offered large downloads such as Fileplanet.  We also
blocked a lot of adult websites this way because a lot
of minors came to our events.  You can use asterisks
in named, so you can use "*.gator.com." (or whatever
the domain is) in your named setup.

You can use arin.net to get the IP classes.  When I
switched to Windows XP, I blocked all Microsoft IP's
from my workstation because I wanted to see when/what
it tried to send to Microsoft.  I wrote a little
parser in perl for ARIN's website to find the current
IP classes and them format them for entry into Tiny
Firewall.
