When you make a manual connection to the serial console, the fingerprint of the server host key is not automatically validated. Validating the server host key's fingerprint protects against potential attacks. The server SSH handshake response is signed with the associated private key. The fingerprint of the server host key is the SHA256 hash of the server host's public SSH key. When you first connect to the serial console, you're prompted to validate the fingerprint of the server host key. If you do not disconnect from the session, Oracle Cloud Infrastructure terminates the serial console session after 24 hours and you must reauthenticate to connect again. When you are finished with the serial console and have terminated the SSH connection, you should delete the serial console connection. Tip You can also use Cloud Shell to connect to the serial console.

Upload the public key portion for the SSH key.

Under Resources, click Console connection.

Click the instance that you're interested in.

Open the navigation menu and click Compute.

During the five-minute timeout, any attempt to connect a new client fails with the following message: channel 0: open failed: administratively prohibited: console access is limited to one connection at a time After five minutes, the connection is closed, and a new client can connect. During this time, no other client can connect. If the client fails, the connection remains active for approximately five minutes. Note Instance console connections are limited to one client at a time. Signing in to an instance from the serial console (optional) You need the private key to connect to the instance console connection using PuTTY.

You can name the key anything you want, but for consistency, use the same name as the private key and a file extension of pub. (Do not use Save public key because it does not save the key in the OpenSSH format.) Select all of the generated key that appears under Public key for pasting into OpenSSH authorized_keys file, copy it using Ctrl + C, paste it into a text file, and then save the file in the same location as the private key. You can name the key anything you want, but use the ppk file extension.

A Key comment is generated for you, including the date and timestamp.

When the key is generated, it appears under Public key for pasting into OpenSSH authorized_keys file.

To generate random data in the key, move your mouse around the blank area in the PuTTY window. Set the Number of bits in a generated key to 2048 if not already set.For the Type of key to generate, accept the default key type of RSA.In the Key menu, confirm that the default value of SSH-2 RSA key is selected.Specify a key type of SSH-2 RSA and a key size of 2048 bits: Find puttygen.exe in the PuTTY folder on your computer, for example, C:\Program Files (x86)\PuTTY.Important Ensure that you are using the latest version of PuTTY, see.
