I'm setting up a ssh server using public key authentication. For that I used this tutorial: http://www.g-loaded.eu/2005/11/10/ssh-with-keys/
I was able to login via ssh. But this works only if I keep the user logged into the server (meaning I have to type my username and password on the server machine and keep it logged in). If I logout the user in the server, when I try to login through ssh it gives: "Permission denied (public key)".
My question is... is there really a need to keep the user logged in the server to use ssh with public key authetntication? Or maybe I've done something wrong?
Additional info: using
ssh firstname.lastname@example.org -v
I get the following output (when there is no user logged in to the server).
