Is there a reason you specifically want RSA and not DSA?  RSA is only in 
protocol 1, I beleive.  You should make sure that your server is configured 
for protocol 1.

For RSA, but the public key in the file $HOME/.ssh/authorized_keys on the 
server system.

If you use protocol 2 (recommended) put the public dsa key in 
$HOME/.ssh/authorized_keys2 (the documentation forgets to mention the final 2 
in the filename).

Make sure that the private keys and the authorized_keys files all have 600 
permissions.

What happens when you do this?  Try 
$ ssh -v -X <remote_host>

You can turn off X in the /etc/ssh/sshd.conf file, so look there first.
