Description Tor Egge 1997-04-15 18:30:01 UTC 
	Some (older) versions of amd or automount, and some versions
	of mount use unprivileged ports when checking for the availability
	of nfsd on the NFS server. 

	[On the SunOS 5.4 client]
	staude# mount ikke:/export/akg2/store /mnt
	nfs mount: ikke: NFS service not responding
	nfs mount: retrying: /mnt

	[On the FreeBSD 3.0-CURRENT NFS server]
	Apr 15 17:17:17 ikke /kernel: NFS request from unprivileged port (129.241.111.23

Fix: As a special case, allow the NFS NULL procedure even when the client
	port is not privileged.
