nss-dontstalkme is a nsswitch module that maps host lookups of well known web trackers to localhost so they become uneffective.

While other solutions such as browser plugins only target specific applications this affects the whole system.


See the README file in the source.

Source Code

The source code is available via:

git clone https://git.sigxcpu.org/cgit/nss-dontstalkme

and can be browsed here.

Pre-built packages

Debian Packages for Jessie can be found here.


If using the Debian package now further setup is required. You need to change /etc/nsswitch.conf otherwise (see the README again). Check if it's working via:

getent ahostsv4 foo.google-analytics.com

This should return only addresses of localhost.


  • Move blocked domains to config file?
