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.

Open up PuTTY Key Generator, click 'Generate,' and follow the on-screen instructions; Once the key is generated, you will need to save the public key. Generating Your SSH Public Key Many Git servers authenticate using SSH public keys. In order to provide a public key, each user in your system must generate one if they don’t already have one. To create a new key pair, select the type of key to generate from the bottom of the screen (using SSH-2 RSA with 2048 bit key size is good for most people; another good well-known alternative is ECDSA). Then click Generate, and start moving the mouse within the Window. Putty uses mouse movements to.

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. 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.

  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.

In a terminal type the following:

This will then provide the following output:

You may either just press enter or specify a path to save the file, the default location is usually best however as SSH will look here for the key automatically when you are connecting to servers.

Next it will ask you for a passphrase:

The passphrase is used to encrypt the key on your hard disk, you will need to enter it each time you want to use your key. Note that you will not see any characters typed as you type your passphrase, this is to prevent a shoulder surfer from seeing how long your password is. This step is optional and you may just press enter, however we do not recommend this as it leaves your key vulnerable to anyone that gains unauthorized access to your computer.

It will then prompt for confirmation of your passprhase:

Enter the password again, or if you selected not to use one just press enter.

Depending on your operating system the following output may vary from system to system, in my case (Debian 9) the following was presented:

You are now done, you have a ssh key pair ready for use. Your private key will be located where you opted to save it. We recommend that you backup this key onto encrypted media as just like your physical keys, if you lose it, you lose access to your property.

Your public key (the key you can share safely) is in the file ending with `.pub`, in the above example this is `/home/user/.ssh/id_rsa.pub`. When asked for your public key you will need to either provide this file, or the contents of it.

To obtain the contents of the file either open it in a text editor or in your terminal type:

Adjusting the path to suit, this will output something like the following:

This entire line is your public key and is required when granting you access to a remote system.
