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.
SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server. Step 1: Check for SSH Keys First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc.
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.
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:
The Terminal window opens with the commandline prompt displaying the name of your machine and your username.
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.
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:
Now you must import the copied SSH key to the portal.
You may see a password prompt like this:
This is because:
id_rsa
) does not match the public key stored with your Triton Compute Service account.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.
ssh-copy-id user@server.example.com[donotprint][/donotprint]
OR
ssh-copy-id -i ~/.ssh/id_rsa.pub user@server1.cyberciti.biz
OR
ssh-copy-id -i ~/.ssh/id_dsa.pub user@server1.cyberciti.biz
OR use specific port on remote host such as tcp port # 4242:
ssh-copy-id -i /path/key/file.pub 'user@server.example.com -p 4242'
Type the following command:
Pokemon yellow download android. Sample outputs:
Type the following ssh-keygen command to generates, manages and converts authentication keys for your workstation / laptop:ssh-keygen
Make sure you protect keys with the passphrase.
Install key in a remote server called www-03.nixcraft.in, enter:ssh-copy-id -i ~/.ssh/id_rsa.pub username@www-03.nixcraft.in
Note: If ssh-copy-id command not found on your system, try the following commands to append/install the public key on remote host:
ssh username@www-03.nixcraft.in 'umask 077; mkdir .ssh'
cat $HOME/.ssh/id_rsa.pub ssh username@www-03.nixcraft.in 'cat >> .ssh/authorized_keys'
OpenSSH offers RSA and DSA authentication to remote systems without supplying a password. keychain is a special bash script designed to make key-based authentication incredibly convenient and flexible (see how to install keychain script on unix). Add following lines to your ~/.bash_profile or shell login file:
Save and close the file.
