This might not work.  I had the problem with passwd, and a 
similar problem with su, su would not allow me to become
root, even when I gave it the correct password and all. 

I am guessing that the problem started when I logged in as 
ast, and copied files from floppy to hard disk.  In the process
ast wound up owning everything, and I had the above problem.  I 
solved it by logging in as root, and then doing the above. 

I do have two questions:

	1. What other files HAVE to be owned by root and
	have the suid set?

	2. How do you tell if suid is set?
