What I Need I need a local DNS filter service. It should tie into svchost for example and automatically start with windows. It should also detect if the user has already set custom DNS servers (for example 8.8.8.8). Then the service should change it to 127.0.0.1, filter all requests and then send them out to 8.8.8.8. Blocking should be possible with asterix notation. The service could be controlled by 2 files: a) blockhosts.conf ------------ *.youtube.* *.*.youtube.* *.ebay*.* *.*.ebay*.* *.wordpress.* +myblog.wordpress.org #----this is a wildcard b) externaldns.conf ----------- 8.8.8.8 8.8.8.9 What do deliver installation and deinstallation .exe or .bat file. should work on Windows XP, Vista, 7 x64, x86 You may use any language you want. Python of .NET preferred.
