hi

heres my sugestion (try "hard way" 
below since its more reliable & secure)

lets say from server1, file1, user1
going to server2, file2, user2
and you can login to both.

easy way (note: possible security hole in server2)
(depends on host names, ip address you put, etc)
(depends if host based auth is allowed by sysad, etc)
-------

put following in .rhosts or .shosts
   file in server2 at user2's home dir:

   server1     user1

-------
hard way (but more secure) (server1 can be anywhere
as long as it holds private key)
-------
1. as user1, generate keys on server1:

   ssh-keygen -t rsa

   this should create ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub 

2. APPEND (or copy) ~/.ssh/id_rsa.pub line to server2's  
   ~/.ssh/authorized_keys on user2's home dir

3. PROTECT ~/.ssh/id_rsa !!!! apply all strict permission
rules. (this is your private key)

if you do this correctly: NO PASSWORDS NEEDED!!!

(you can put "scp file1 server2:file1" or whatever
on your shellscript withouht worrying about passwords)

pls adjust accordingly above, i'm working mostly
from memory and random notes..I'm sure it worked on
my systems.


GOOD LUCK

JondZ
