If you don't mind I would like you to clarify the steps to address the 
config above

The machine I am ssh ing from is local
The machine I am ssh ing to is remote

To do as above, do  I create a .~ssh/config file with the following contents 
on the local machine and restart sshd /etc/rc.d/sshd restart

Host remote.domainname  #which is the connection name I am assuming
User root
Port 22
HostName remote.domainname   # which is the hostname of the remote machine

I am not sure what the permissions should be though.  Do they need to be 
changed?  do I need to change the /root/.ssh/id_rsa    and   id_rsa.pub to 
the systemuser? or should they stay the same.  Or do I change the 
authorized_keys permissions  The error I am getting is a permission denied 
which makes me think that I need to change some of the permissions. 
Currently the perms are 600 on both the /root/.ssh/id_rsa  and   id_rsa.pub 
and the /home/systemuser/authorized_keys

Thanks and Regards
