 +===== Troubleshooting =====
 +If you still get a password prompt, try to correct these items:
 +
 +  * Your home directory ~ and your ~/.ssh directory on the remote machine must be writable only by you: %%rwx------%% and %%rwxr-xr-x%% are fine, but %%rwxrwx---%% is no good, even if you are the only user in your group (if you prefer numeric modes: 700 or 755, not 775).
 +  * Your private key file (on the local machine) must be readable and writable only by you: %%rw-------%%, i.e. 600.
 +  * Your ~/.ssh/authorized_keys file (on the remote machine) must be readable (at least 400), but you'll need it to be also writable (600) if you will add any more keys to it.  I had to make this writable only by root (644) to correct a password prompt issue recently.
