remote hosts access problem on solaris

hey guys, i am on a box named pluto and i need to be able to log into another box named genesis. i need to be able to ssh into genesis as root and not get asked for the password. what file do i need to edit on genesis to make this happen? i searched for the .rhosts file it doesn't seem to exist.

any thing else I can do?

i'm doing this all through a script file. there isnt' going to be any smooth sailing if after i run the script i keep getting asked to input the password. that wouldnt' be fun at all. can someone please help

correct .rhosts may not be existing. you can always create one in the HOME.
