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 at xxxxxx.com -p 1234 The output shows the logging-on routine wants 3 types of authentication. Surely one successful authentication is sufficient ?
