Introduction.
- SSH(Secure Shell) is a networking protocol that is used to encrypt communication between two hosts. In the following sections, we will see how to perform a client-side and server-side configuration of hosts and access the remote server using ssh.
Prerequisites.
- The following are requirements for this to work. 1. Both hosts must be on and connected to the internet and be reachable 2. Permissions and authentication details for the user account on the remote server. 3. A SSH client should be installed on the client's computer. 4. A SSH server should be installed on the server. 5. Firewall rules allowing the ssh connection on the server.
Initial setup.
- We have two hosts, the client, and the server. The IP address of the server is 192.168.100.62 - this is where we will connect to using the client and it is also where we will install the openssh-serverserver software package. Now to test its reachability from our localhost. Its file system is as follows:
Server Configuration.
- First, we update the remote repositories and the system. For this we write: Once we have updated and upgraded the system, we install openssh-serverpackage as follows: Now, let's confirm that it was successfully installed by checking its status: We can also check its status by writing: We have confirmed that it was successfully installed, the next step is to start it to check if there are any is…

- After we are done we can close the ssh connection on the client-side by using exitas follows: On the server we stop the ssh server using systemctlcommand and confirm it is closed by checking its status:
Summary.
- Secure Shell(SSH) is a cryptographic networking protocol used for encrypting communication between two hosts. In this article, we have seen how to access a remote server securely using ssh. We have also seen how the server is configured with sshand how the client connects to the server.
