Well, you can use the following command to see the connetion between you server and the other machine:

netstat -a | grep `uname -n` | sort

This will give you an idea what machine is connet to your server and what ports are used. Some time is hard to tell who is using the application.

msnr, NFS:
as long as the connection (means traffic) is established, you see connects to port 2049 (or whatever is configured).
The same problem applies to any connection controlled by the portmapper, you need to use tcp_wrapper to control it.

another good tool for listing network connections to your machine is lsof.

show all (i)nternet network connections
lsof -i

show all ssh(port 22) connections
lsof -i :22

you can get it as a package from http://www.sunfreeware.com/
