Hello Public keys doesnt work like that. The server has no clue if the private key used had password protection or not. You can however (I think, please correct me if i'm wrong), use pam, and force both password (/etc/passwd) local password, AND only show this password login, if an valid key is used. Basicly, you use ssh-key only, and then use pam to ask for the password later on.. -- Lars On Feb 15, 2008 2:08 PM, Samuel Soulard <darkmasterhalo@xxxxxxxxx> wrote: > Hi guys, > > I wanna know if it is possible to force authentication to a OpenSSH > server by a password and by a RSA Key(With a Passphrase on it).
