Usage

From source file:Main.java

static public void main(String args[]) throws Exception {
    int port = 80;

    NetworkInterface ni = NetworkInterface.getByName("name");
    Enumeration e = ni.getInetAddresses();
    if (!e.hasMoreElements())
        return;/*from w  ww.j ava  2  s  .c  o  m*/
    InetAddress ia = (InetAddress) e.nextElement();

    ServerSocket ss = new ServerSocket(port, 20, ia);
    System.out.println("Listening");
    Socket s = ss.accept();
    System.out.println(s);
