Validate that the password-based login does not work. Task 5: Test access using the new SSH key pairĮstablish a new SSH session to the ESXi host using the new SSH key pair.Īfter testing access with the new SSH keys in Step 5, you must disable the password based login for security reasons.Įdit the /etc/ssh/sshd_config file and change the PasswordAuthentication setting to no. Replace the existing private key or add a new private key. SSH into the ESXi host using the password you have configured in the previous step.Įdit the authorized_keys file located at /etc/ssh/keys-opc/. Task 4: Replace the SSH key with a new private key ![]() Reload the SSH service by running the command: /etc/init.d/SSH restart. To enable password based login for the opc user, edit the /etc/ssh/sshd_config file.Ĭhange the PasswordAuthentication setting to yes and save the file. Task 3: Enable password based authentication for the ESXi host Press ALT F1 to access the Console and log in using opc user and SDDC password Once the connection is established, you can see the DCUI. For this tutorial, we will use localhost:5900. Once the connection has started, open VNC Viewer and establish a connection to the Console using the command localhost:localport. Start Windows PowerShell or Terminal, run the following command and follow the prompts to begin the session. Start-Job sleep 5 plink.exe -i C:\Keys\ssh-key-converted.ppk -N -L 5900:localhost:5900 -P 5905 localhost -l ur6vlkost37m2rxa ![]() Paste the copied command to a text editor. Note: If you are using a Linux/Mac machine, follow the appropriate steps. Once the console connection has changed to active state, complete the following steps.Ĭlick on the kebab icon on the right of the connection and then click Copy VNC connection for Windows. Task 2: Access Console connection or DCUI of the ESXi host Generate an SSH key pair or upload your own public key, in this example we will create a new key pair.Ĭlick Create console connection and wait for the state of the connection to change to Active. Select the first ESXi host of the Oracle Cloud VMware Solution SDDC. Open the Oracle Cloud Console navigation menu, click Compute and then click Instances. Task 1: Create a Console connection to the ESXi host Replace lost SSH keys for Oracle Cloud VMware Solution ESXi hosts by temporarily enabling password based login. ![]() Install putty or plink.exe (a command-line interface to the PuTTY backend).Configure the appropriate permissions for managing compute instances to create instance console connections.Configure the required permissions to access the Oracle Cloud VMware Solution SDDC.Review and complete the prerequisite steps in the following section: After adding the new private key, you can disable the password based login for better security. The workaround solution is to access the Direct Console User Interface (DCUI) of the ESXi host, enable password based login, and then SSH into the ESXi host and replace the authorized keys. If the private SSH key is misplaced or lost, you cannot SSH into the ESXi host. To SSH into the Oracle Cloud VMware Solution SDDC compute instance or ESXi hosts, the default method is to use a private key matching to the public key that was provided during the provisioning process. If for some reason the keys are lost, you can enable password based login to the ESXi host and replace the SSH Keys. ![]() During the deployment of the Software Defined Data Center (SDDC), you must provide a SSH key pair which can be used to SSH into the ESXi hosts. It offers complete control using familiar VMware tools. Oracle Cloud VMware Solution provides a customer managed, native VMware-based cloud environment, installed within a customer’s tenancy.
