Question

A developer needs passwordless SSH access from her workstation to a build server (buildsrv). She has no existing SSH keys. Which sequence correctly sets up key-based authentication without manually editing files on the server?

Accepted Answer

Run ssh-keygen -t ed25519 on the workstation, then ssh-copy-id developer@buildsrv

Answer

Run ssh-keygen -t ed25519 on buildsrv, then copy /root/.ssh/id_ed25519 to the workstation

Answer

Copy the workstation's ~/.ssh/id_ed25519 (private key) into buildsrv's ~/.ssh/authorized_keys

Answer

Run ssh-keygen -t ed25519 on the workstation, then scp ~/.ssh/id_ed25519 developer@buildsrv:~/.ssh/authorized_keys
