- * RLoginClient is very similar to
- * {@link org.apache.commons.net.bsd.RCommandClient},
- * 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 org.apache.commons.net.bsd.RCommandClient}.
- * <p>
- * As with virtually all of the client classes in org.apache.commons.net, 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 org.apache.commons.net.bsd.RExecClient#disconnect 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 org.apache.commons.net.bsd.RExecClient#getInputStream 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 org.apache.commons.net.bsd.RExecClient#getErrorStream getErrorStream() }
- * will always return null.
- * The standard input of the remote process can be written to through
- * the output stream returned by
- * {@link org.apache.commons.net.bsd.RExecClient#getOutputStream getOutputSream() }
- * .
