PAM issues

["William A. Mahaffey III" <wam%hiwaay.net@localhost>]

I am trying to get some of my LAN boxen to backup other LAN boxen. In 
particular, I am trying to get an Intel Q6600-based FC14-x86_64 server 
to backup my /etc directory on my AMD 4256EE-based server running NetBSD 
6.1.5. I also go the other way & that works mostly AOK. When I try to 
SSH into the 4256EE from the Q6600, I observe the following on the 4256EE:


4256EE1 # tail -20 /var/log/authlog; date

I have a public-key from the Q6600 in my /root/.ssh/authorized_keys 
file, but I still get errors trying to SSH in. My PAM files are 
box-stock, as is/are my sshd config file(s). Any clues as to how to get 
this to work appreciated. TIA & have a nice weekend.
