For openssh, to log on w/o a password, on the computer from which you
want to log on, run "ssh-keygen -t rsa" to generate a ssh2 keypair
(without the "-t rsa" it would make an ssh1 keypair). For ease of use,
give an empty passphrase. Accept the default location for the keypair, in
~.ssh.
The ssh2 keypair is id_rsa, id_rsa.pub; the ssh1 is identity,
identity.pub. I assume ssh2 is the default when you use ssh. For the
ssh2 keypair, copy id_rsa.pub from the computer from which you want to log
w/o a password to ~./ssh/authorized_keys2 on the computer to which you
want to log on w/o a password.
