Note: SSH keys are always generated as a pair of public ( id_rsa.pub) and private ( id_rsa) keys. Then generate a new set of keys with: ssh-keygen -t rsa -b 4096 -C check that your keys exist with the ls -al ~/.ssh command and ensure that the output is similar to the one listed above.

Save the file and youвЂ™re ready to SSH into those machines with commands like:ДЄnd thatвЂ™s all there is to creating an SSH config file to be used on macOS. You could then create each host configuration entry (below that), leaving out the User option, like so: Where USERNAME is the user on the remote machines. You could configure that at the top of the config file with two simple lines:

LetвЂ™s say you use the same account on all of your data center servers on the IP address scheme 192.168.1.x. This makes it so much easier for you to remote into those servers from your Apple laptop or desktop. Just make sure, at a minimum, you include the Host and Hostname options. You can create as many configurations in that file as you need (one for every server in your data center), each with different options. To SSH into our Nextcloud server, youвЂ™d only have to type the command: If youвЂ™re not using SSH KEY authentication (which you should), youвЂ™d need to remove the IdentityFile line. WeвЂ™re also going to enable key authentication for the connection. WeвЂ™re going to name this server вЂњnextcloudвЂќ so we can easily remember how to Secure Shell into it. For example, say this is a Nextcloud server at IP address 192.168.1.20 and the username is vega. In that directory, create the new file with the command: Once it opens, change into your user SSH directory with the command: With those at the ready, letвЂ™s make this happen. The only thing youвЂ™ll need is a MacBook or iMac that includes SSH and some remote servers to connect to. SEE: Identity theft protection policy (TechRepublic Premium) What youвЂ™ll need How do you do that on macOS? Let me show you. What if I told you that SSH can use a configuration file to make it much easier? By making use of the SSH configuration file, you can configure an entire data center worth of SSH connections such that you could issue a command: Ssh what happens if you remote into 10 or 20 different machines throughout the day, each with different usernames and IP addresses? That can get a bit confusing after a while.

Open your macOS terminal app and issue a command like:ДЄs long as your usernames are the same on both ends, youвЂ™re good to go, but if your user names arenвЂ™t the same, that command might look like: Generally speaking, SSH is quite easy to use. You probably use SSH to connect to remote machines for admin purposes. Jack Wallen shows you how to make SSH connections even easier from your macOS machine.
