52.Tn NFS
53server on
54.Ar host .
55By default it prints the names of all hosts that have
56.Tn NFS
57file systems mounted
58on the host.
59See
60.%T "NFS: Network File System Protocol Specification" ,
61RFC 1094,
62Appendix A,
63and
64.%T "NFS: Network File System Version 3 Protocol Specification" ,
65Appendix I,
66for a detailed description of the protocol.

69.Bl -tag -width indent
70.It Fl a

96.Sh HISTORY
97The
98.Nm
99utility first appeared in
100.Bx 4.4 .
101.Sh BUGS
102The mount daemon running on the server only has an idea of the actual mounts,
103since the
104.Tn NFS
105server is stateless.
106The
107.Nm
108utility will only display the information
109as accurately as the mount daemon reports it.
