Like I said, is blocking port 53 enough to prevent DNS requests on my local
DNS? Or can somehow a DNS request be made through port 80/443 and lead to a
DNS leak?
I have vlc set to use socks proxy in 127.0.0.1:9150 which I do to use it
through Tor Browser Bundle (using the Tor process that TBB starts). I am not
certain if vlc will respect proxy settings for DNS requests, so I made a few
tests closing port 53 on gufw. However I am unfamiliar with how Trisquel (any
GNU/Linux distro actually) will handle DNS requests, and would like some
insight from some more experienced users :)
Btw, I did the tests like this:
TBB running, vlc set to proxy, port 53 blocked, tried to access http live
stream, and it worked.
TBB not running, vlc set to proxy, port 53 blocked, tried to access http live
stream, it fails.
TBB not running, vlc not set to proxy, port 53 blocked, tried to access http
live stream, it fails.
TBB not running, vlc not set to proxy, port 53 open, tried to access http
live stream, it works.
lsof -i usually gave me the expected results too (vlc set to proxy vlc
connects to 9150, vlc not set to proxy vlc connects directly to stream ip).
That is a good sign right?
Sorry, I know this is related to general GNU/Linux firewall settings, but
just Trisquel's, but since I am using Trisquel and some people here know more
about this than me, thought I would ask :)
Thanks in advance!
