[kwlug-disc] wrapping DNS calls per process

[Jason]

Can you run this process in a container - LXC/Docker?  Then you could
control the networking separately from the main machine, including DNS
requests. This would give you better resource isolation anyway.

Alternatively, you could set up a Linux networking namespace, and bind all
the commands this process uses to use that namespace, so you can isolate
all of the networking configuration to be separate from the main system.
This is what containers use under the hood, you could just set it up
manually, and this would create a Linux virtual network interface for the
process to use.

For reference:  https://man7.org/linux/man-pages/man8/ip-netns.8.html

Cheers,
Jason
