how to do a sudo after logging in?

[ronald.van.de.kuil@nl.abnamro.com]

Hello,

I want to sudo after logging in with my user id but I don't know how to
insert the password.

I have written the following method:

public void connect(String aAddress, String aUser, String aSudoUser, String
aPassword, int aPort) throws IOException {

      Socket serverSocket     = new Socket(aAddress, aPort);
      SSH2Transport transport = new SSH2Transport(serverSocket, prefs,
createSecureRandom());

      System.out.println("SSH2-login on " + aAddress + " with user " +
aUser);

      try {
            lClient = new SSH2SimpleClient(transport, aUser, aPassword);
            lConsole = new SSH2ConsoleRemote(lClient.getConnection(), null,
System.err);

            //until here it works fine

            if (null != aSudoUser){
                  String lCommand = "sudo su - " + aSudoUser;
                  System.out.println("SSH2IO>" + lCommand + "<");
                  lConsole.command(lCommand );

                  /**
                  * Here the program asks for my password depending on the
last time I logged in
                  * The thread continues without waiting for input and
prints my working directory
                  * instead of the working directory of the user I want to
su to
                  "/

                  lConsole.command("pwd");
                  String response = receive();
                  System.out.println(response);
            }
            } catch (SSH2Exception e) {
                  System.out.println("Trouble connecting to aAddress " +
e);
            }
      }
}

I seem to be getting  a prompt from standard err asking me for a password
but I don't manage to insert the password.
It doesn't help to inserting the password by adding
lConsole.command(aPassword);

When I do a sudo from a terminal, the code doesn't ask for my password
anymore but the result is still that I get my personal
working directory printed.

Can anyone point me to some sample code where a sudo is done?
