 * RLoginClient is very similar to
 * {@link},
 * from which it is derived, and uses the rcmd() facility implemented
 * in RCommandClient to implement the functionality of the rlogin command that
 * first appeared in 4.2BSD Unix.  rlogin is a command used to login to
 * a remote machine from a trusted host, sometimes without issuing a
 * password.  The trust relationship is the same as described in
 * the documentation for
 * {@link}.
 * <p>
 * As with virtually all of the client classes in, this
 * class derives from SocketClient.  But it relies on the connection
 * methods defined  in RcommandClient which ensure that the local Socket
 * will originate from an acceptable rshell port.  The way to use
 * RLoginClient is to first connect
 * to the server, call the {@link #rlogin  rlogin() } method,
 * and then
 * fetch the connection's input and output streams.
 * Interaction with the remote command is controlled entirely through the
 * I/O streams.  Once you have finished processing the streams, you should
 * invoke {@link disconnect() }
 *  to clean up properly.
 * <p>
 * The standard output and standard error streams of the
 * remote process are transmitted over the same connection, readable
 * from the input stream returned by
 * {@link getInputStream() }
 * .  Unlike RExecClient and RCommandClient, it is
 * not possible to tell the rlogind daemon to return the standard error
 * stream over a separate connection.
 * {@link getErrorStream() }
 *  will always return null.
 * The standard input of the remote process can be written to through
 * the output stream returned by
 * {@link getOutputSream() }
 * .

public class RLoginClient extends RCommandClient
     * The default rlogin port.  Set to 513 in BSD Unix and according
     * to RFC 1282.
    public static final int DEFAULT_PORT = 513;

     * The default RLoginClient constructor.  Initializes the
     * default port to <code> DEFAULT_PORT </code>.
    public RLoginClient()

     * Logins into a remote machine through the rlogind daemon on the server
     * to which the RLoginClient is connected.  After calling this method,
     * you may interact with the remote login shell through its standard input
     * and output streams.  Standard error is sent over the same stream as
     * standard output.  You will typically be able to detect
     * the termination of the remote login shell after reaching end of file
     * on its standard output (accessible through
     * {@link #getInputStream  getInputStream() }.  Disconnecting
     * from the server or closing the process streams before reaching
     * end of file will terminate the remote login shell in most cases.
     * <p>
     * If user authentication fails, the rlogind daemon will request that
     * a password be entered interactively.  You will be able to read the
     * prompt from the output stream of the RLoginClient and write the
     * password to the input stream of the RLoginClient.
     * <p>
     * @param localUsername  The user account on the local machine that is
     *        trying to login to the remote host.
     * @param remoteUsername  The account name on the server that is
     *        being logged in to.
     * @param terminalType   The name of the user's terminal (e.g., "vt100",
     *        "network", etc.)
     * @param terminalSpeed  The speed of the user's terminal, expressed
     *        as a baud rate or bps (e.g., 9600 or 38400)
     * @exception IOException If the rlogin() attempt fails.  The exception
     *            will contain a message indicating the nature of the failure.
    public void rlogin(String localUsername, String remoteUsername,
                       String terminalType, int terminalSpeed)
    throws IOException
        rexec(localUsername, remoteUsername, terminalType + "/" + terminalSpeed,

     * Same as the other rlogin method, but no terminal speed is defined.
    public void rlogin(String localUsername, String remoteUsername,
                       String terminalType)
    throws IOException
        rexec(localUsername, remoteUsername, terminalType, false);
