I have heard that adding

auth    sufficient      pam_rootok.so

to  /etc/pam.d/rsh should be enough, but I had experiences that 
I needed to add
/root/.rhosts.



I'm using "dsh" extensively for cluster maintenance, it is a Debian
package.


For systems which you cannot really log in as root with rsh, 
to initially set up, you could use 

dsh -ica 


to login to all hosts interactively :P
