OS X ships with an actual OpenSSH client.
Provided that the public key was already authorized on the server you want to work with, how do you make sure that OS X won’t ask you for the key’s passphrase every time you log in? Configure OS X SSH client

We’ll leave out the details on how to add your key to remote servers for the next time. The command to copy contents of your public key to clipboard is simple: cat ~/.ssh/id_rsa.pub | pbcopy The public key is what you will share to server admins, or add yourself to remote servers, in order to be able to login to those systems without a password.
When you generated the SSH key, you have actually generated 2 files: the private key ~/.ssh/id_rsa and the public key ~/.ssh/id_rsa.pub. It is the public key you’ll need to share or add to servers. Remember, this file should never be shared with anyone. Now you have your key generated and stored in ~/.ssh/id_rsa. Make sure to actually change the command to include your email and device name. So you may want to adjust the command before you run by passing your good comment in the -C switch: ssh-keygen -t rsa ~/.ssh/id_rsa -C (MacBook Air)" An (arbitrary) identifier of the machine or device where you intend to use the keyįollowing these rules a good comment might look like (MacBook Air)īy default, ssh-keygen will try to be smart in generating the comment, but not smart enough: the comment will include your machine’s hostname and folks who find your key added to their system, will not know how to reach you if there’s a need to collaborate about server tasks or your key.Your email address, where people can reach you.To be nice to others, and simply for housekeeping purpose, make sure that the key’s comment includes: Choose commentĪ good SSH key has a good comment. And don’t worry, you won’t be bothered to enter it every time you use SSH / SFTP. So make sure that you choose a very strong passphrase for protecting your SSH key. The magic of it is achieved by the Keychain and SSH agent components of the operating system. With OS X, you can have the convenience of password-less login to a server even when your key is passphrase-protected. With empty passphrase, you don’t have to enter it every-time, and with long passphrase, you have to? Fear not! Surely enough, you think it’s a sane choice because then you save yourself a lot of time. In many tutorials online, they’d say it is OK to specify an empty passphrase. To construct the correct arguments for it, we need to first…: Choose passphrase To generate the SSH key, you will run ssh-keygen in Terminal app. Let’s walk through the proper setup of your native SSH client in OS X. I still prefer to use my MacBook Air for work, just because I can type ssh web and start working with my server right away.Ĭould it be even better in regards to SSH? Just when I could definitely answer “No”, I got an email from a client, who was asking for instructions on how to generate SSH key for use with FileZilla to connect to their server.Īfter trying to recap the proper instructions for them, I found how I could improve my own use of SSH in OS X, and also make it more secure.

And the native OpenSSH client is the killer feature.įast forward to 2019, and my failure to build a proper Hackintosh using high-end PC components, rendered it useful only for mostly one thing at present – watching movies on Windows.
Working with CLI in OS X feels much like Linux. When I got more familiar with the use of SSH keys for password-less login, I became a happier SSH user.Ī few years later, I started using OS X and initiating SSH connections from it felt awkward without Putty, until I discovered iTerm.īut getting more familiar with the OS X system itself, I found myself really hooked up to it for mainly one reason – it’s built from FreeBSD.

If you want to install NGINX, Varnish, and lots of useful performance/security software with smooth yum upgrades for production use, this is the repository for you.Īctive subscription is required. We have by far the largest RPM repository with NGINX module packages and VMODs for Varnish.
