2409 SunRPC servers often require that client requests
2410 originate from a privileged port (i.e. a port in the
2411 range 0 < portnr < 1024).
2412 An administrator who wishes to reserve some of these
2413 ports for other uses may adjust the range that the
2414 kernel's sunrpc client considers to be privileged
2415 using these two parameters to set the minimum and
2416 maximum port values.
