known_hosts is used on the client for protocol 1 connections, to verify 
that the server is who it claims to be. There's also a known_hosts2 file 
for protocol 2. On the server you need the files authorized_keys and 
authorized_keys2 to hold the public keys authorized to connect to that 
account. Your private key will be in one of the files identity (for RSA) or 
id_dsa (for DSA) on the client.

Also be careful about permissions. The .ssh directory must not have group 
or world access. Set it to 0700. The server won't accept PK connections if 
that directory is too loose.
