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.
