If an authorization dialog appears, click the "Authorize" button and proceed.

If the SSH connection is successful, the following window will appear.

Next, we will describe how to set up a virtual machine for a user other than the user who logged in with GCP.

Registering a New User to the Virtual Machine

The following is an example of how to create a private key and a public key for "ssh", using the "ssh-keygen" command.

Creating a Private Key and a Public Key for "ssh"

The following is an example of how to create a private key and a public key for "ssh", using the "ssh-keygen" command.

Example: (key file name is "id_rsa")

# ssh-keygen -q -t rsa -b 4096 -C '""' -N '""' -f id_rsa

Registering a New User to the Virtual Machine

On the virtual machine page, click the "Edit" button at the top to see the "Edit" screen.

On the virtual machine "Edit" screen, click "Add Item" under the "Security and Access" -> "SSH Authentication Key" section.

When the "Add Item" box opens, paste the contents of the public key file you just created ("id_rsa.pub" in the example). Then enter the user name as well, with a space after the pasted content ("gcp-user" in the example).

After entering the information, click the "Save" button at the bottom of the screen.

Making a Note of the External IP Address

An external IP address will be required to log in through "ssh". In the middle of the virtual machine page there is a section called "Network Interface'', and within that there is an item called "External IP Address'', so please make a note of this address.

Log In to the Virtual Machine and Prepare for Initial Setup

The following section describes how to prepare for logging in to the virtual machine and performing the initial setup.

Logging In to the Virtual Machine

As explained earlier, with GCP, there are two ways to login to the virtual machine.

The following describes what information you will need to log in to the virtual machine using the "ssh" command, and the same information will be required to log in using the "SSH" button. To log in to the virtual machine, you need the full path to the private key file you created in "Registering a new user to the virtual machine", the user name you set, and the external IP address that you had written down.

# ssh (user name)@(external IP address) -i (full path to private key file)

If you are logging in using an SSH client on Windows, please refer to the link below.
Log in to KUSANAGI 9 with Windows "ssh"

Switching to the "root" User

To switch to the "root" user, enter the following.
