Because of this your neighborhood Pc doesn't understand the distant host. This will take place The very first time you connect to a brand new host. Type Certainly and push ENTER to continue.
As soon as that is done click "Help save Public Essential" to save lots of your public essential, and reserve it in which you want While using the title "id_rsa.pub" or "id_ed25519.pub" determined by no matter whether you chose RSA or Ed25519 in the sooner step.
Soon after completing this step, you’ve efficiently transitioned your SSH daemon to only reply to SSH keys.
) bits. We would suggest normally employing it with 521 bits, Considering that the keys are still modest and possibly safer than the more compact keys (even though they should be Harmless too). Most SSH consumers now assist this algorithm.
