I've been searching like crazy trying to find a solution to a problem that seems like it ought to be very simple.
All I want to do is block all internet access at the system level, except for a handful of hostnames.
OpenDNS cannot do this, Dan's Guardian is ridiculously complicated, and I can't find a way to set up a proxy server at system level, only at browser level.
Can you, for example, block all traffic in the hosts.deny file and then add the needed sites to hosts.allow? Or can it be done through ufw?
