You may see something in the log messages during the connection phase that expose the problem. - - Check the /var/log/messages file on the host for debug messages from sshd. Are there any errors that indicate why public key authentication doesn't work? - - Check the /etc/ssh/sshd_config file contents. Is PubkeyAuthentication enabled? You can also change the LogLevel setting if you need more information emitted to /var/log/messages. Don't forget to send SIGHUP to sshd whenever you change sshd_config. - - Check the permissions on the the ~user/.ssh directory and the authorized_keys file. They have to be sufficiently tight (700 and 600, typically). Hope that helps, and post back here with any further questions.
