Usage

From source file:examples.ssh.X11.java

public static void main(String... args) throws Exception {
    SSHClient ssh = new SSHClient();

    // Compression makes X11 more feasible over slower connections
    // ssh.useCompression();

    ssh.loadKnownHosts();//from w  w  w.j  av a  2 s. c om

    /*
     * NOTE: Forwarding incoming X connections to localhost:6000 only works if X is started without the
     * "-nolisten tcp" option (this is usually not the default for good reason)
     */
    ssh.registerX11Forwarder(new SocketForwardingConnectListener(new InetSocketAddress("localhost", 6000)));

    ssh.connect("localhost");
    try {

        ssh.authPublickey(System.getProperty("user.name"));

        Session sess = ssh.startSession();

        /*
         * It is recommendable to send a fake cookie, and in your ConnectListener when a connection comes in replace
         * it with the real one. But here simply one from `xauth list` is being used.
         */
        sess.reqX11Forwarding("MIT-MAGIC-COOKIE-1", "26e8700422fd3efb99a918ce02324e9e", 0);

        Command cmd = sess.exec("firefox");

        new Pipe("stdout", cmd.getInputStream(), System.out).start();
        new Pipe("stderr", cmd.getErrorStream(), System.err).start();

        // Wait for session & X11 channel to get closed
        ssh.getConnection().join();
