Setup SSH Key

Setup SSH Key

To setup a server you’re going to need an SSH key. You can add keys in the Cato Console after signing in by navigating to:

Compute → SSH Keys → Add SSH Key

You might already have an ssh key you’d like to use at

  ~/.ssh/id_ed25519.pub

Otherwise you can use the ssh-keygen CLI utility:

  ssh-keygen -t ed25519 -C "your_email@example.com"

This should generate two files

• id_ed25519
• id_ed25519.pub

Copy paste the contents of id_ed25519.pub to the SSH Public Key field.

Logging in to your server

You can use the key you generated to log in to your server using the ssh-agent utility. This allows you to use the key without first copying it to the remote server.

  eval $(ssh-agent -s)       # start the agent if it's not already running
  ssh-add ~/.ssh/id_ed25519  # add your key to the agent
  ssh -A user@remote-host    # use the -A option to forward the agent to the remote-host

Remember to treat your private key with the same security considerations as you would a password.
