If other remote connection tools such as PuTTy, Xshell, and SecureCRT are not installed or do not work properly, you can access your instances by using a VNC management terminal in the ECS console.
Prerequisites
The instance to which you want to connect is in the Running state. The VNC password is reset if it is your first time to connect to the instance after the instance is created. For more information, see Change the VNC password.
Context
The VNC password is used to log on to a VNC management terminal in the ECS console, whereas the instance password is used to log on to the instance.
You can use a VNC management terminal to connect to an instance to solve specific issues. The
The following table lists some of the issues.
