title: java UnknownHostException
body: <p>I am trying this simple tutorial from oracle : <a href="http://www.oracle.com/technetwork/java/socket-140484.html" rel="nofollow">http://www.oracle.com/technetwork/java/socket-140484.html</a> (the Example 1 ). Here you have the two classes, <a href="http://java.sun.com/developer/onlineTraining/Programming/BasicJava2/Code/SocketServer.java" rel="nofollow">SocketServer.java</a> and <a href="http://java.sun.com/developer/onlineTraining/Programming/BasicJava2/Code/SocketClient.java" rel="nofollow">SocketClient.java</a>. When I run the client ( after I started the server), I get "Unknown host: kq6py.eng" in the console. I am on MAC OS X. What should I do? I tried setting the proxy settings in Eclipse but nothing changed.</p>
