How to smartly block sites ?

Hello,

For blocking sites, I use lists that I import into the HOSTS file, both for windows and ubuntu. This is the high level solution. Unfortunately, wildcards are not allowed and the lists are huge. On the other hand, I know the addon BLOCKSITE which allows wildcards but this is the browser only solution.
Do you know a smart way to block sites with wildcards or anything. A sort of mix "Hosts" and "Blocksite" at high level.
I use Firefox under Windows XP and Ubuntu (dual boot).

Thank you.

 

Acrylic DNS Proxy will allow you to use regular expressions in its hosts file. I think DNSKong allows wildcards.

 

DNSKong blocklist can accommodate "between-the-dots" matching patterns as well as patterns anchored by dots.
Here are a few quick examples:

sexhound
adserver.focalink
cn

Above, the first pattern would match (and block)
sexhound.com
sexhound.co.uk
www.sexhound.pl
BUT NOT
sexhounds.com nor www.essexhound.com

The second would match and block
adserver.focalink.com
ww2.adserver.focalink.net
BUT NOT
www.focalink.com nor adserver2.focalink.net

The third would block any hostname bearing a Chinese country code TLD as well as
cn.happypuppy.com
www.cn.pl
