50utility shows status information about the
51.Tn NFS
52server on
53.Ar host .
54By default it prints the names of all hosts that have
55.Tn NFS
56file systems mounted
57on the host.
58See
59.%T "NFS: Network File System Protocol Specification" ,
60RFC 1094,
61Appendix A,

89.Sh HISTORY
90The
91.Nm
92utility first appeared in
93.Bx 4.4 .
94.Sh BUGS
95The mount daemon running on the server only has an idea of the actual mounts,
96since the
97.Tn NFS
98server is stateless.
99The
100.Nm
101utility will only display the information
102as accurately as the mount daemon reports it.
