SSH is a secure networking protocol that allows remote login to servers. After logging in, a user can run commands on the server, access files, and transfer data.
SSH is enabled by default on most DigitalOcean servers, but there are a few steps you can take to make sure that it’s working properly.
To begin, open a terminal window and navigate to the server’s root directory. To check that SSH is enabled, you can use the following command:
$ ssh
If the command returns a response, then SSH is enabled and you can proceed to the next step. If the command returns an error, then SSH may not be enabled on the server and you will need to enable it.
To enable SSH, you can use the following command:
$ sudo apt-get install ssh
If the command returns a response, then SSH is enabled and you can proceed to the next step. If the command returns an error, then you will need to install SSH on the server.
Once SSH is enabled, you can login to the server using the following command:
$ ssh username@hostname
If you are not logged in to the server already, you will be prompted for a username and password. Once you have logged in, you can run commands on the server by using the command line. To exit the SSH session, you can use the following command:
$ exit
You can also use the ssh command to connect to other servers. To do this, you will need to know the server’s IP address. You can find this information by using the following command:
$ ip addr
After you have found the server’s IP address, you can connect to it using the following command:
$ ssh server_ip.
