Revision 13. </p> <p>Utility functions to create a single server socket which able to listen on both IPv4 and IPv6. Inspired by: <a href="http://bugs.python.org/issue17561" rel="nofollow">http://bugs.python.org/issue17561</a></p> <p>Expected usage:</p> <pre class="prettyprint"><code>&gt;&gt;&gt; sock = create_server_sock(("", 8000)) &gt;&gt;&gt; if not has_dual_stack(sock): ... sock.close() ... sock = MultipleSocketsListener([("0.0.0.0", 8000), ("::", 8000)]) &gt;&gt;&gt; </code></pre> <p>From here on you have a socket which listens on port 8000, all interfaces, serving both IPv4 and IPv6. You can start accepting new connections as usual:</p> <pre class="prettyprint"><code>&gt;&gt;&gt; while True: ... conn, addr = sock.accept() ... # handle new connection </code></pre> <p>Supports UNIX, Windows, non-blocking sockets and socket timeouts. Works with Python &gt;= 2.6 and 3.X.</p>
