Tutorial: Connect to Access Server via SSH using PuTTY⁠

Download the PuTTY installation package to install both PuTTY and PuTTYgen: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html.

Follow the program's installation steps.

Launch the PuTTYgen app.

Click Conversions > Import Key.

Select the key file you used to generate your server.

Enter the passphrase for your key if needed.

• PuTTYgen loads your key file.

Click Save private key.

Name your key and save it to a file location.

Close PuTTYgen.

Launch the PuTTY tool.

Enter the static IP address of your server in the Host Name (or IP address) field.

In the left-hand navigation, navigate to SSH > Auth > Credentials.

Click Browse next to Private key file for authentication and select the private key you generated with PuTTYgen.

Click Session, enter a name for this SSH session in the Saved Sessions text field, and click Save. (This saves your configuration so you can load it quickly next time.)

Click Open to launch the SSH session.

After clicking Open, PuTTY presents a message that it hasn't seen this server before. It's safe to click Accept.

When prompted, sign in as your root user.

Upon successful key validation, you connect to the server, and the command line interface is displayed.
