    copied!<p>I've <strong>just</strong> started with this section of the tutorial. I only have a basic understanding of what ports are, etc.</p> <p>I tried to run this code:</p> <pre><code>import java.io.*; import java.net.*; public class EchoClient { public static void main(String[] args) throws IOException { Socket echoSocket = null; PrintWriter out = null; BufferedReader in = null; try { echoSocket = new Socket("taranis", 7); out = new PrintWriter(echoSocket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader( echoSocket.getInputStream())); } catch (UnknownHostException e) { System.err.println("Don't know about host: taranis."); System.exit(1); } catch (IOException e) { System.err.println("Couldn't get I/O for " + "the connection to: taranis."); System.exit(1); } BufferedReader stdIn = new BufferedReader( new InputStreamReader(System.in)); String userInput; while ((userInput = stdIn.readLine()) != null) { out.println(userInput); System.out.println("echo: " + in.readLine()); } out.close(); in.close(); stdIn.close(); echoSocket.close(); } } </code></pre> <hr> <p>"Don't know about host: taranis. Java Result: 1" </p> <p>Is the error catch I get. From my limited understanding; is the echo-server something which exists on my machine? If that's the case, what do I need to do to get this running? Or am I way off? Also why have they chosen "taranis" as a parameter?</p> <p>Ive also replaced "taranis" with "localhost" to see what happened. It ended up catching an IOException this time.</p> <p>EDIT: So I've found that the echo server is disabled by default in win7 and have activated it. However I cant even connect to it on telnet. I think I may just be in over my head. I've also tried the sockets you have recommended with no success.</p>
