2 days ago Tweet If you’re a developer, on devops or a system admin you probably use an SSH key to log into remote servers. I am typically on multiple projects at one time and some organizations require I generate a unique SSH key in order to work with them. Oct 06, 2018 First thing that you need to do on your macOS machine is to create a directory that will store your SSH keys. Then you will generate a public and private key for your account, launch the Terminal and punch in some commands: Create a.ssh Directory. Change to the home directory. Cd / Create a SSH directory name.ssh and move into it. Mkdir.ssh; cd.ssh.
You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.
Generating a new SSH key. Open Terminal Terminal Git Bash. Paste the text below, substituting in your GitHub email address. $ ssh-keygen -t rsa -b 4096 -C '[email protected]' This creates a new ssh key, using the provided email as a label. Generating public/private rsa key pair. Aug 08, 2016 Do you hate typing in your username and password for GitHub everytime you make a push? Well that ends today because we are going to learn to generate an SSH key.
Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.
About Terminal
Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.
To open the macOS Terminal, follow these steps:
- In Finder, choose Utilities from the Applications folder.
- Find Terminal in the Utilities listw.
- Open Terminal.

The Terminal window opens with the commandline prompt displaying the name of your machine and your username.
Generating an SSH key
An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use
ssh-keygen
to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.To generate SSH keys in macOS, follow these steps:
- Enter the following command in the Terminal window.This starts the key generation process. When you execute this command, the
ssh-keygen
utility prompts you to indicate where to store the key. - Press the ENTER key to accept the default location. The
ssh-keygen
utility prompts you for a passphrase. - Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.
You will need to enter the passphrase a second time to continue.
After you confirm the passphrase, the system generates the key pair.
Your private key is saved to the
id_rsa
file in the .ssh
directory and is used to verify the public key you use belongs to the same Triton Compute Service account.Never share your private key with anyone! |

Your public key is saved to the
id_rsa.pub
;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this:Importing your SSH key
Now you must import the copied SSH key to the portal.
- After you copy the SSH key to the clipboard, return to your account page.
- Choose to Import Public Key and paste your SSH key into the Public Key field.
- In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
- Add the key. It will now appear in your table of keys under SSH.
Troubleshooting
You may see a password prompt like this:
This is because:
- You did not enter the correct passphrase.
- The private key on your Macintosh (
id_rsa
) does not match the public key stored with your Triton Compute Service account. - The public key was not entered correctly in your Triton account.
