Well, to answer that question it is necessary to see the
contents of your sshd_config, and ~/.ssh/authorized_keys

The manpage says:  "Authentication mechanisms that may
require DNS include RhostsRSAAuthentication, Hostbased-

in a key file.  Configuration options that require DNS
include using a USER@HOST pattern in AllowUsers or
DenyUsers."
