How Do I Generate Public and Private Keys of the FusionCompute Node Serving as the SSH Server?

Hello, friend!

Have a nice day!

What's the version of your FusionCompute?

Hello, friend!

The following uses FusionCompute 8.0 as an example.

1. Use PuTTY to log in to the node for which the known_hosts file is to be updated.

Ensure that the management IP address and username gandalf are used to establish the connection.

The system supports the login authentication using a password or private-public key pair. If you use a private-public key pair to authenticate the login, see How Do I Use PuTTY to Log In to a Node in Key Pair Authentication Mode?

2. Run the following command and enter the password of the root user to switch to the root user:

su - root

3. Run the following command to disable user logout upon system timeout:

TMOUT=0

4. Run the following command to obtain the public key of the SSH server to be logged in and add the public key to the known_hosts file:

ssh-keyscan -t rsa IP address of the SSH server >> /root/.ssh/known_hosts

If multiple IP addresses are configured for the SSH server, this operation must be performed for each IP address.

The known_hosts file is updated if information similar to the following is displayed in the x86 architecture:

#192.168.128.10 SSH-2.0-OpenSSH_X.X

The known_hosts file is updated if information similar to the following is displayed in the ARM architecture:

#192.168.61.100 SSH-2.0-OpenSSH_X.X

5. Run the following command to connect to the SSH server and check whether the login is successful:

ssh gandalf@IP address of the SSH server

Hope this can help you!
