openssh auto login

[Bill Rees]

Hi All,
       I upgraded a redhat 7.3 system to FC4 and one of the problems 
that has surfaced is that the ssh auto login feature that worked on 7.3, 
no longer works.  According to the man page for ssh, there is a 
challenge/response phase to ssh authentication types where a 
private/public key pair are involved.  A simple private/public key pair 
on the client and the public key on the server.

    The web has mostly the same description of things to do with the 
only added item the ssh-agent.  Ufortunately, I'm trying to get a cron 
job to access my server via rsync -e ssh.  So can anyone clue me in to 
what I've missed?  I made sure the challenge response feature was 
enabled in sshd_config, that authorized key authentication was enabled, 
and PubkeyAthenitication was enabled.
