Hint this:
--------------------------- SecureCRT ---------------------------
连接到会话 192.168.1.100 失败 : The server has disconnected with an error. Server message reads: A protocol error occurred. Change of username or service not allowed: (root,ssh-connection) -> (zoujiaqing,ssh-connection)
--------------------------- Sure---------------------- -----
This is because the username in the SecureCRT settings does not match the username you entered when logging in. You can change it here: Options -> Session Options -> Connection -> SSH2 -> After the username is modified, the login is normal, which can disable the server The ROOT is logged in (for security).
