In /root/.ssh

on every machine

ssh-keygen -tdsa
save as <hostname.id_dsa>
empty for no passphrase
cp hostname.id_dsa myprivatekey

one one machine

create a file "config" with one stanza for every machine like this

Host xxxx
User root
Compression yes
Protocol 2
RSAAuthentication yes
StrictHostKeyChecking no
ForwardAgent yes
ForwardX11 yes
IdentityFile /root/.ssh/myprivatekey

replace xxxx with the name of each host

create a file authorized_keys2 with vi. do not cut and paste

read each public key into this file (:r xxx.pub) 

scp config and authorized_keys2 to each machine

try ssh xxxx

works for me
