Re: Tunnel DNS queries

["Huzeyfe ONAL(Gmail)" <huzeyfe.onal () gmail com>]

Hi,

you can tunnel your udp connections( of course  your dns queries too)
through an ssh connection using netcat and OpensSSH [1]

And if your application supports socks(socks5 supports udp) proxying
then you can use OpenSSH's SOCKS proxy forwarding feaure (-D ).
