Have you checked /var/log/auth.log on the server? It might be worth starting up a server on a temporary port with the -ddd option to get detailed debugging from it. FWIW I use public key authentication all the time, including to a Debian stable host, and it's working fine for me. -- Colin Watson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
