Hallo,
I wanted to avoid typing-in my password every occasion I remotely
logged-on to a server.
I created my SSH keys and copied the public part to the server and
renamed it authorized_keys.
My command line is: ssh root@xxxxxxxxxx -p 1234
The output shows the logging-on routine wants 3 types of authentication.
Surely one successful authentication is sufficient ?
