How to set up public key authentication for SSH

How to set up public key authentication so that you are not
prompted for a password. Here’s the quick way to do it:

$ ssh-keygen -t dsa
–> press ENTER when prompted for a pass-phrase
$ scp ~/.ssh/id_dsa.pub rhillegas@…:

$ ssh rhillegas@…

minotaur$ cat id_dsa.pub >> .ssh/authorized_keys

Now you should be able to log on without being prompted.

A simpler way is to use the ssh-copy-id command.
