If you're creating the public key for the FIRST TIME on this computer,
be VERY careful about permissions.  Sometimes using the defaults when
creating the ~/.ssh/authorized_keys2 OR the ~.ssh/ directory, it will
give WRITE permissions to the GROUP.  This will cause your keys to FAIL
every time.  This drove me nuts for the longest time, back when I tried
first tried to get RSA/DSA authorization working.  (read permissions are
OK on the file and directory, but not required)
