UTdns is a nifty tool which proxies all UDP-based DNS requests through TCP DNS. This is usefull if you have to tunnel DNS through TCP-only tunnels. This respectively was the requirement for the development of this tool.
Have a look at this article on cypherpunk.at for some details.
To build utdns either download the latest package from
releases and run ./configure,
make, and make install as usual or directly clone this directory from Github
and run ./bootstrap to initialize the autotools. Then run ./configure,
make, and make install. In the latter case you need to have installed the
GNU Autotools packages autoconf and automake.
