"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What the portmapper does is provide a known location for clients to see what services are available on the host.  In general the services provided include nfs, rwho, rwall, and some other convenient but unnecessary services.  It is possible, however, to create your own service, have it registered with the portmapper, and available to other machines.
