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
An SSH key consists of a pair of files. One is the private key, which you should never give to anyone. No one will ever ask you for it and if so, simply ignore them - they are trying to steal it. The other is the public key. When you generate your keys, you will use ssh-keygen to store the keys in a safe location so you can authenticate with. Dec 18, 2019 In this tutorial, we will walk through how to generate SSH keys on Ubuntu 18.04 machines. We will also show you how to set up an SSH key-based authentication and connect to your remote Linux servers without entering a password. Finally, the new key pair authentication method can be tested by giving ssh username@username in the terminal window. Ssh root@x.x.x.x Theory of The Keys and How They Work. The key pair is a part of the SSH standard which is used to connect to a remote host over an unsecured network. To generate an SSH key in Windows 10. Which means you can use ssh-keygen to generate SSH keys. Read on as we walk you through the entire process. Into the terminal window and press enter.
Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.
Jan 09, 2018 Then slowly replace the authorized key on your remote servers one by one with the newly generated Ed25519 public-key. Open up your terminal and type the following command to generate a new SSH key.
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-keygenutility prompts you to indicate where to store the key.Press the ENTER key to accept the default location. The
ssh-keygenutility 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:
Generate Ssh Public Key From Private Key
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.
Ssh Key Setup
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.
You generate an SSH key through Mac OS X by using the Terminal application. Once you upload a valid public SSH key,Gerrit can authenticate you based on this key.

Warning
You will need to enter the passphrase a second time to continue.
After you confirm the passphrase, the system generates the key pair and you will see output like this:
Your private key is saved to the id_rsa file in the .ssh subdirectory of your home directory and is used to verifythe public key you use belongs to your Gerrit account.
Warning
Never share your private key with anyone! Ever! We mean it!
Your public key is saved to a file called id_rsa.pub in the .ssh subdirectory of your home directory. You can copyit to your clipboard using the following command:
Now you can head over to Gerrit, go to settings and paste your public key as described here.
Gerrit is using the special port 29418 instead of the default SSH port 22 which has to be configured accordingly. This can be done in your local ~/.ssh/config file which would contain the following sections then:
Ssh Key Github
