Creating a Non-root User with sudo Privileges


SSH to your server. When i write this command i get a strange answer:

The authenticity of host ‘Ip adress (public ip adrss)’ can’t be established.
ECDSA key fingerprint is SHA256:EzRSbO6liuOcM2Vd+HhjOlSvOynPMtHEK8qGoXEFSco.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Why is that ? What should i do ?

SSH does that every time you connect to a new server it has never seen before. Just say yes.

Thank you for reply, very kind.
