Hi all,

We are trying to identify the NFS clients connected to host
192.168.16.82 and the shares they have mounted.

To do this we are using following command

showmount -a 192.168.16.82
this gives output as

All mount points on ASHWINI:
*:/home/ashwini/share
*:/home/mac
127.0.0.1:*
192.168.16.81:*

But the problem we are facing is even if the client with IP address
192.168.16.81 unmounts the share using "umount command", still the
showmount -a command shows that 192.168.16.81 client is connected..

The command we are using to unmount the share on client's machine is
"umount /mnt/ashwini"

Can anybody tell us where are we going wrong??
Is it the nfs service on the client's machine causing the problem??

Any help will be appreciated.

Thanks in advance,
Ashwini
