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,
62and
63.%T "NFS: Network File System Version 3 Protocol Specification" ,
64Appendix I,
65for a detailed description of the protocol.

68.Bl -tag -width indent
69.It Fl a , Fl -all

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