Bug#321523: ssh.1.gz: no password bootstrap example
Perhaps describe protocol 2 before protocol 1.
And perhaps add this example to show protocol 2 users how to get
rid of being asked for passwords, as an example is worth 1000 words:
$ ssh nurdsburg2 mkdir .ssh
$ scp .ssh/id_dsa.pub nurdsburg2:.ssh/authorized_keys #or append is better?
$ ssh nurdsburg2
Welcome to nurdsburg2. Last login: Aug 6 03:42 from nurdsburg1
nurdsburg2$ chmod -R go= .ssh #if important?
