Change root password automatically

Shell Programming and Scripting

I need to change root password automatically in some servers all three months. I want to run this process in one of the servers and reply it to the others. The password must be known by the administrator.

I hope it's a system admin question . As most of the people who are visting this link may not aware much of system admin.

Yes, I am a system administrator but not for a long time. My systems are Suse LInux 9 and 10

you can do it by writing simple script to change the root password. I'm using "expect" to automate the interactive password request.
