39.Sh NAME
40.Nm mountd

43mount requests
44.Sh SYNOPSIS
45.Nm
46.Op Fl P Ar policy
47.Op Fl dn
48.Op Ar exportsfile
49.Sh DESCRIPTION
50.Nm
51is the server for
52.Tn NFS
53mount requests from other client machines.
54.Nm
55listens for service requests at the port indicated in the
56.Tn NFS
57server specification; see
58.%T "Network File System Protocol Specification" ,
59RFC1094, Appendix A and
60.%T "NFS: Network File System Version 3 Protocol Specification" ,
61Appendix I.
62.Pp
63Options and operands available for
64.Nm mountd :
65.Bl -tag -width Ds
66.It Fl P Ar policy
67IPsec
68.Ar policy
69string,
70as described in
71.Xr ipsec_set_policy 3 .
72Multiple IPsec policy strings may be specified by using a semicolon as
73a separator. If conflicting policy strings are found in a single line,
74the last string will take effect. If an invalid IPsec policy string is used
75.Nm
76logs an error message and terminates itself.
77.It Fl d
78Enable debugging mode.
79.Nm
80will not detach from the controlling terminal and will print
81debugging messages to stderr.
82.It Fl n
83This flag used to indicate that clients were required to make requests
84from reserved ports, but it is now no longer functional. It
85is only provided for backwards compatibility. Requests
86are checked for reserved ports on a per-export basis, see
87.Xr exports 5 .
88.It Ar exportsfile
89The
90.Ar exportsfile
91argument specifies an alternative location
92for the exports file.
93.El
94.Pp
95When
96.Nm
97is started,
98it loads the export host addresses and options into the kernel
99using the
100.Xr mount 2
101system call.
102After changing the exports file,
103a hangup signal should be sent to the
104.Nm
105daemon to get it to reload the export information.
106After sending the SIGHUP
107(kill \-s HUP `cat /var/run/mountd.pid`),
108check the syslog output to see if
109.Nm
110logged any parsing errors in the exports file.
111.Pp
112After receiving SIGTERM,
113.Nm
114sends a broadcast request to remove the mount list from all the clients.
115This can take a long time, since the broadcast request waits for each
116client to respond.
117.Sh FILES
118.Bl -tag -width /var/run/mountd.pid -compact
119.It Pa /etc/exports
120the list of exported filesystems
121.It Pa /var/run/mountd.pid
