Configuring SSH access

How to configure SSH access to a remote Linux system.

Generate a local key

ssh-keygen -t ed25519 -C "[email protected]"

A few things to note:

• ~/.ssh/id_ed25519 is your private key. Keep it safe!
• ~/.ssh/id_ed25519.pub is your public key

On your Linux system

• Edit ~/.ssh/authorized_keys on the remote system, and add your ~/.ssh/id_ed25519.pub file to it.

or you can run

ssh-copy-id -i ~/.ssh/id_ed25519.pub username@hostname
