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: Let’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, you’d only have to type the command: If you’re not using SSH KEY authentication (which you should), you’d need to remove the IdentityFile line. We’re also going to enable key authentication for the connection.

We’re going to name this server “nextcloud” 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, let’s make this happen. The only thing you’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 you’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:Īs long as your usernames are the same on both ends, you’re good to go, but if your user names aren’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. Click the Add Public Key button, and paste the public key into the SSH Key box, click Add Key and you're done.How to use an SSH config file on macOS for easier connections to your data center servers Once there, you will see a button to add your public key. Login to Beanstalk and click on Your Name > SSH Keys. Once your key pair is generated, you can add it to Beanstalk. This can be done by running the command: $ cat ~/.ssh/id_rsa.pub | pbcopy Now that the keys are generated, copy it to your clipboard for the next step. The key fingerprint is: key's randomart image is: Your public key has been saved in /Users/username/.ssh/id_rsa.pub. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /Users/username/.ssh/id_rsa.
Enter file in which to save the key (/Users/username/.ssh/id_rsa): Created directory '/Users/username/.ssh'. The output should look something like this: your-mac:~ home$ ssh-keygen -t rsa Generating public/private rsa key pair. Make sure to set a strong pass phrase for the key. When it asks for a pass phrase, don't leave it empty. It will ask for location, just accept the default location (~/.ssh/id_rsa.pub) by pressing return. To generate a key pair, run the command: $ ssh-keygen -t rsa Make sure you are in the home directory by entering: $ cd ~/ First, open up Terminal to access the command line. This process only requires a few steps on macOS. To authenticate with Beanstalk for Git, you will need to generate an SSH key pair. Beanstalk supports RSA, DSA and EdDSA SSH keys.
