Ssh Generate Key Pair Mac

 
  1. Generating SSH keys (Mac OS X) Last updated 29 February 2012. This will step you through the process of generating a SSH keypair on Mac OS X. Begin by opening your Terminal, generally found in the 'Utilities' subdirectory of your 'Applications' directory.
  2. Issue the following command at a shell prompt (by default, Mac OS Terminal uses a bash shell): ssh-keygen -t rsa -b 2048. This will create a RSA public/private key pair in the.ssh directory below your account’s home directory. For example: Location: /.ssh (where is the home directory) Private key file name: idrsa.

Using a passphrase is much more secure! Without one you have to be very careful not to expose your private key - if someone else gets a copy of it they will be able to login with your account. Linux Generate a key pair: $ ssh-keygen -t rsa Generating public/private rsa key pair. Jun 17, 2014  In the following article, we’re going to run through the process of creating a public/private SSH key-pair in OS X 10.9. Once this is done, we’ll configure our GitHub account to use the public key, create a new repository and finally pull this repository down onto our machine via SSH. Supported SSH key formats. Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported. Create an SSH key pair. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the. For example, you can use ssh-keygen (a tool provided with the standard OpenSSH installation) to create a key pair.

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.

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:

  1. In Finder, choose Utilities from the Applications folder.
  2. Find Terminal in the Utilities listw.
  3. 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:

  1. /generate-keys-for-google-analytics-access.html. 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.

  2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.

  3. 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.

Create Ssh Key Pair Mac

  1. After you copy the SSH key to the clipboard, return to your account page.
  2. Choose to Import Public Key and paste your SSH key into the Public Key field.
  3. 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.
  4. 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.

What are my next steps?

Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines.

In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.

Gypsum-gateway logins are restricted to SSH keys. See the instructions below for how to generate a keypair for your operating system.

NOTE: The instructions below describe how to generate a key pair without a passphrase. Using a passphrase is much more secure! Without one you have to be very careful not to expose your private key -- if someone else gets a copy of it they will be able to login with your account.

Generate a key pair: Your public key is /home/$USER/.ssh/id_rsa.pub. Send an email to ciirsm@cs.umass.edu with that file attached. Once it is installed you will be notified and able to login to gypsum-gateway.

Mac

Open the Terminal app. From the command-line, generate a key pair: Your public key is

Windows

These instructions are for the PuTTY terminal emulator. It is possible to login with other clients but you're on your own in figuring out how to generate SSH keys.

Download and install PuTTY and friends. I recommend the 32-bit or 64-bit MSI 'Windows Installer' as that will include all of the utilities needed to generate and manage SSH keys.

Apple Create Ssh Key Pair Mac Os X

  1. Start PuTTYgen by going to Start --> All Programs --> PuTTY --> PuTTYgen
  2. Click the Generate button.
  3. Wiggle the mouse to generate randomness until the key is generated.
  4. Optional: Enter a comment in the Key comment field. This can be helpful to identify this particular key if you're managing multiple key pairs.
  5. Click on the Save public key button. Pick a location to save the public key. I created a subfolder in Documents called SSH Keys and named the key gypsum-gateway-public.key.
  6. Click on the Save private key button. Pick a location to save the private key. I created a subfolder in Documents called SSH Keys and named the key gypsum-gateway.ppk. The private key must have the .ppk extension!
  7. The contents of the public key are in the windows at the top of the key generator. Copy it into an email to ciirsm@cs.umass.edu. Once it is installed you will be notified and able to login to gypsum-gateway.
  8. Create a PuTTY profile to save your server settings. Start PuTTY and enter gypsum‑gateway.cs.umass.edu as the Host Name (or IP address) you'll be connecting to.
  9. Click on the Connection --> Data catgeory in the left-hand panel. Enter the username you'll be logging in as in the Auto-login username field.
  10. Expand the Connection --> SSH category, then click on Auth. Add your private SSH key where it says Private key file for authentication by clicking on the Browse.. button and selecting your key.
  11. Go back to the Session category. Under Saved Sessions enter a name for this session (I usually enter the hostname I'm connecting to) and click Save.
  12. Click Open to login to the server.
