Linux : How to show connected client of NFS export on the server?

Here is how to quickly show the connected clients to a NFS server. It might be useful to know before rebooting the server!

On the server, execute the following command (replace <> with the NFS server IP address) :

netstat -an | grep <NFS.Server.IP>:2049

Example :

netstat -an | grep 192.168.45.32:2049

You should see a similar output :

tcp 0 0 192.168.45.32:2049 192.168.45.52:840 ESTABLISHED
tcp 0 0 192.168.45.32:2049 192.168.45.22:980 ESTABLISHED
