A tool for putting hosts into a blackhole.
Webnull is a command line program that lets you stop your computer from being able to reach certain websites.
Usage: sudo webnull deny example.com
Above, example.com will be added to your hosts file and routed to localhost. The next time you try to visit example.com your browser won't be able to find it.
Later, sudo webnull allow example will re-allow access to the site for five minutes.
sudo webnull allow -am will allow access to all blocked sites until tomorrow morning.
See webnull -h for full usage.
pip install webnull
$ sudo webnull deny example.com
$ sudo webnull deny https://example.com/foo/bar
$ sudo webnull allow example.com
$ sudo webnull allow -t 30 example.com
$ sudo webnull allow -a
$ sudo webnull allow -am
