Tor project makes oniux. When in linux one starts process, e.g. ``` <br>
oniux bash ```, it moves networking via tor process.<br>
<br>
Question:<br>
Is there a similar trick for DNS only. So that we can run some test <br>
process, and inside of it all DNS requests can be set the way testing needs.<br>
