40.Os
41.Sh NAME
42.Nm showmount
43.Nd show remote nfs mounts on host
44.Sh SYNOPSIS
45.Nm
46.Op Fl a | d
47.Op Fl e3
48.Op Ar host
49.Sh DESCRIPTION
50The
51.Nm
52utility shows status information about the
53.Tn NFS
54server on
55.Ar host .
56By default it prints the names of all hosts that have
57.Tn NFS
58filesystems mounted
59on the host.
60See
61.%T "NFS: Network File System Protocol Specification" ,
62RFC 1094,
63Appendix A,
64and
65.%T "NFS: Network File System Version 3 Protocol Specification" ,
66Appendix I,
67for a detailed description of the protocol.
68.Pp
69The following options are available:
70.Bl -tag -width indent
71.It Fl a
72List all mount points in the form:
73.Bd -ragged -offset indent -compact
74.Ar host : Ns Ar dirpath .
75.Ed
76.It Fl d
77List directory paths of mount points instead of hosts.
78.It Fl e
79Show the
80.Ar host Ns 's
81exports list.
82.It Fl 3
83Use mount protocol Version 3, compatible with
84.Tn NFS
85Version 3.
86.El
87.Sh SEE ALSO
88.Xr mount 8 ,
89.Xr mountd 8 ,
90.Xr mount_nfs 8
91.Sh BUGS
92The mount daemon running on the server only has an idea of the actual mounts,
93since the
94.Tn NFS
95server is stateless.
96The
97.Nm
98utility will only display the information
99as accurately as the mount daemon reports it.
100.Sh HISTORY
101The
102.Nm
103utility first appeared in
104.Bx 4.4 .
