While you have now learned how to enable SSH, it’s equally important to know how to turn it off in case you wish to disable any remote login in future. If SSH is on, you will get a message that reads “Remote Login: On” (refer to Figure 2). However, you can use a command to know if SSH has been successfully enabled. Once you complete step 2, you will not get any message to confirm that SSH has been enabled. Note: In Mac, SSH is also known as Remote Login.

Provide the password and press enter (as shown in Figure 1 below). You will be required to input your user password when you run the command. It is necessary to add sudo because the command requires administrator privileges. To enable SSH, enter and execute the -setremotelogin command as follows: You can do this by searching “terminal” using the Spotlight search option of your computer or navigating through Applications > Utilities > Terminal. In this section, we will take you through the process of enabling SSH. SSH remote login to an Apple computer is disabled by default. Enabling SSH to Securely Access a Remote Mac’s Shell Finally, the client logs into the server. Afterwards, the server negotiates parameters and creates a secure channel for the client. The server sends a public cryptography key to the client and the key is used to verify the identity of the SSH server. Once the server receives the connection request, encryption negotiation begins. To establish a connection with an SSH server, the client needs to initiate a request with an SSH server.

The connection layer, which manages the connection between the client and the server after a successful authentication.

The authentication layer, which sends the supported authentication methods to the client.

The transport layer, which establishes secure communication between the client and the SSH server.

Secure Shell leverages a client-server model to connect an SSH client application (where the session is displayed) with an SSH server (where the session runs). In addition, it can be configured to allow port forwarding by mapping the default SSH port to an available port number on the destination. Aside from providing strong encryption and secure remote connections, SSH encrypts the data during file transfers or while securely managing network infrastructure components. SSH keys can and should be used in any situation where there is an unsecured network. The keys work collaboratively to provide authentication between the client and the remote system. SSH encrypts the communication with a remote system by utilizing a pair of SSH keys which are cryptographic in nature and made up of a public and private key pair.

It encompasses a cryptographic network protocol and the suite of utilities that implement the protocol. SSH - also known as Secure Socket Shell or Secure Shell - is a secure network protocol that allows users, especially system admins, to securely access remote devices. In this article, you will learn how to enable SSH for accessing a remote Mac’s shell securely. Therefore, we have decided to explore some of the most important macOS commands in this series. It is the magic that saves you time and makes you more efficient. All you need to do is to send a few text commands, and you can make your way through both simple or complex tasks easily. It lets the admin perform tasks quickly and efficiently on the local computer (directly or remotely). Terminal.app is a utility that gives the admin direct access to the Unix underpinnings of the macOS operating system.

A great way for Apple Admins to become smart is to master as many commands as possible. In a world of endless possibilities where everyone seeks to work smarter not harder, IT and system admins cannot afford to be left behind.
