sendPassword

protected IoWriteFuture sendPassword(Buffer buffer,
                                     ClientSession session,
                                     String oldPassword,

                              throws IOException

Sends the password via a SSH_MSG_USERAUTH_REQUEST message. If old and new password are not the same then it requests a password modification from the server (which may be denied if the server does not support this feature).

Parameters:

buffer - The Buffer to re-use for sending the message

session - The target ClientSession

oldPassword - The previous password

newPassword - The new password

Returns:

An IoWriteFuture that can be used to wait and check on the success/failure of the request packet being sent

Throws:

IOException - If failed to send the message.
