Hello,

I have looked in several places but cannot find a way of only accepting
clients, connecting using ssh, whos public keys I know of already. If a
client is not already known it should be rejected. I want this to be
globally defined for the whole server, and not user specific. How di I
configure sshd correctly to get this functionality?

Today when a new client connects it is accepted as long as the correct
username/password is supplied, but this is not enough for me. I want only a
controlled few to be able to connect to my server.

I have a i686 running RH 7.3 with OpenSSL.

Thank you in advance
