It provides the +client with the first answer it gets, trimming the answer so it fits +in an UDP packet. +</p> + +<p> + dnsfunnel is especially useful for distributions using the +<a href="https://musl-libc.org">musl</a> libc, which does not support +TCP DNS transport. It was originally written to be used in the +<a href="https://alpinelinux.org/">Alpine Linux</a> distribution. +</p> + +<hr /> + +<h2> Installation </h2> + +<h3> Requirements </h3> + +<ul> + <li> A POSIX-compliant system with a standard C development environment. +The system must also support <tt>chroot()</tt> </li> + <li> GNU make, version 3.81 or later </li> + <li> <a href="//skarnet.org/software/skalibs/">skalibs</a> version +2.10.0.0 or later.
