Why the broker?

(sudo) ncat -kul 53 --sh-exec "minibill@89.16.178.89 \"ncat -u 8.8.8.8 53\""

Isn't this enough?

Regards,
Nuno

My ISP has filters on the dns.
Thanks to ncat I could bypass them.

ncat -l -k -u -p 53 --sh-exec "ncat localhost 1100" 2> /dev/null
ncat --broker -l -k -p 1100
ncat localhost 1100 --sh-exec "ssh minibill@89.16.178.89 \"ncat -u 8.8.8.8 53\""

That command would open a ssh connection for every dns request,
which is something I want to avoid, as ssh connection takes ~1.5 seconds
