[LIP] Automate password change

Hi,

I have a shell script which automates the pasword
change in a number of machines. 

#!/usr/bin/sh
for SERVER in `cat hostlist`
do
(sleep 5;echo $userid;\
sleep 5;echo $password;\
sleep 2;echo passwd;\
sleep 5;echo $password;\
sleep 2;echo $new_passwd;\
sleep 2;echo $new_passwd;\
sleep 2;exit;) | telnet $SERVER
done

The script works fine for a normal userid. But the
script fails if I su to root to change the root
passwd. To login as root I need to get in as normal
user and su to root. I cannot use 'Expect Utility' as
I am not allowed to install anything. For example the
following script FAILS.

#!/usr/bin/sh
for SERVER in `cat hostlist`
do
(sleep 5;echo $userid;\
sleep 5;echo $password;\
sleep 2;echo su root;\
sleep 5;echo $root_password;\
sleep 5;echo passwd;\
sleep 5;echo $root_password;\
sleep 2;echo $new_passwd;\
sleep 2;echo $new_passwd;\
sleep 2;exit;) | telnet $SERVER
done

Can someone help me? Any pointer will be of help.

regards & Thanks
Pinku
