Hello, friend!

VNC allows users to remotely log in to an ECS on the UI. Only password authentication is supported. You can use a password to log in to an ECS using VNC in any of the following scenarios:

1. The authentication mode of the ECS is password.

2. The authentication mode of the ECS is a key. The password of user root is reset using the key.

3.  When creating an ECS, you cannot set the authentication mode, but you have obtained the password of user root in the image used to create the ECS.

If an existing user logs in to an ECS using VNC, other users cannot log in to the ECS using VNC. You can modify related configuration items to allow other users to log in to the ECS.

If you confirm that all the preceding conditions are met, you can reset the password of the ECS.

1. Log in to the ECS console as a VDC administrator or VDC operator.

2. Ensure that the ECS whose password is to be reset is stopped.

3. In the Operation column of the ECS whose password is to be reset, choose More > Instance Settings > Reset Password.

4. Set a new password for the ECS and confirm the new password.

5 Click OK.

The new password takes effect after the ECS is restarted.

Hope this helps!

Hello, friend!

1. Failed to Log In to the ECS Using VNC

What OS is your ECS?

Are you sure you're using the correct password?

2. How does an ECS communicate with external systems?

You need to configure an EIP so that the ECS can connect to the network through the EIP.

Have a nice day!

Regarding Point 2 for ECS Having Direct Network Access to Connection , Through an External Network How can we make it Accessible from the out side network , Lets Say External Network is 10.10.20.0/24 and 10.10.20.1 is Gateway of External Network , I create ECS and Assigned IP is 10.10.20.50 , I check from my Client the Local Gateway Configured on Switch Side for External Network is Reachable , but ECS IP is not Reachable what could be the Cause of that Issue

Dear Saad_AK,
The remote login function is implemented using customized ports. Therefore, before attempting to log in remotely, ensure that the port to be used is not blocked by the firewall. For example, if the remote login link is xxx:8002, ensure that port 8002 is not blocked by the firewall.
If the client OS uses a local proxy and the firewall port cannot be configured on the local proxy, disable the proxy mode and then try logging in remotely.
