I’ve used this thrice in three days, so I’m just keeping a copy for myself.

Sourced (i.e. blatant copy-paste) from: http://arbib.it/tag/shortest-passwordless-ssh-tutorial/

That in turn got it from http://blogs.translucentcode.org/mick/archives/000230.html

Begin:

``` sourceCode bash local$ ssh-keygen -t dsa local$ scp ~/.ssh/id_dsa.pub remote:~/ local$ ssh username@remote remote$ cat ~/id_dsa.pub » ~/.ssh/authorized_keys remote$ chmod 644 ~/.ssh/authorized_keys remote$ exit local$ ssh username@remote


Now instead of the normal password you should be asked for the password
you entered for your dsa key. This isn't passwordless yet but shows that
ssh is using the key.

Note: Leave Key password blank to have passwordless authentication

Fixes for possible problems:

``` sourceCode bash
chmod 0600
authorized_keys
ln -s authorized_keys2 authorized_keys (or viceversa)
