Host raspberrypi
    HostName 87.106.61.62
    Port 22223
    User root
    IdentityFile ~/.ssh/id_rsa

Generate and copy SSH key:

ssh-keygen -t ed25519 -C "cursor-raspberrypi"
ssh-copy-id -p 22223 root@87.106.61.62

Test connection:

ssh -p 22223 root@87.106.61.62

In Cursor:

• Install "Remote - SSH" extension
