To use PuTTY to connect to a server, you can follow these steps:
1. Download and install PuTTY on your local computer. You can download PuTTY from the following link: https://www.putty.org.
2. Open PuTTY on your local computer. In the "Host Name (or IP address)" field, enter the IP address or hostname of the server you want to connect to.
3. In the "Connection type" field, select "SSH" as the connection type.
4. In the "Category" pane on the left, expand the "Connection" option, and then click on "Data". In the "Auto-login username" field, enter the username that you want to use to log in to the server, usually "root".
5. Click on the "Open" button to initiate the connection. If this is the first time you are connecting to the server, you may see a security alert dialog asking if you want to add the server's host key to the cache. Click on "Yes" to continue.
6. When prompted, enter the password for the server.
7. Once you have authenticated, you will be connected to the server and you will see a command prompt where you can enter commands to interact with the server.
It's important to note that using password authentication can be less secure than using a private key file for authentication. Private keys are typically more difficult to compromise than passwords, as they are not transmitted over the network and are not easily guessed. Therefore, it is generally recommended to use private key authentication whenever possible.
