A quick nfs question. First I run showmount -e on a machine:

/shared user1.mydomain.com

But then I run showmount -a on the same machine:



How is this difference possible? In the above example, showmount -e
shows that /shared has only been exported to one host, user1. Yet other
hosts have mounted it. I don't understand. Is this a result of some
network magic? Or is a program sitting on nfs, such as sfs? Thanks for
any help.
