.Op Ar exportsfile
.Sh DESCRIPTION
.Nm
1993-03-21 12:45:37 +03:00
is the server for
.Tn NFS
mount requests from other client machines.
.Nm
1993-03-21 12:45:37 +03:00
listens for service requests at the port indicated in the
.Tn NFS
server specification; see
.%T "Network File System Protocol Specification" ,
RFC1094, Appendix A and
.%T "NFS: Network File System Version 3 Protocol Specification" ,
Appendix I.

.Pp
Options and operands available for
.Nm mountd :
.Bl -tag -width Ds
.It Fl d
Enable debugging mode.
.Nm
will not detach from the controlling terminal and will print
debugging messages to stderr.
1993-03-21 12:45:37 +03:00
.It Fl n
Do not require that clients make requests from reserved ports.
This option is only provided for backwards compatibility. Requests
are checked for reserved ports on a per-export basis, see
.Xr exports 5 .

.It Ar exportsfile
1993-03-21 12:45:37 +03:00
The
.Ar exportsfile
1997-03-08 16:47:08 +03:00
argument specifies an alternative location
1993-03-21 12:45:37 +03:00
for the exports file.
.El
.Pp
When
.Nm
is started,
it loads the export host addresses and options into the kernel
using the mount(2) system call.
After changing the exports file,
a hangup signal should be sent to the
.Nm
daemon to get it to reload the export information.
After sending the SIGHUP
(kill \-s HUP `cat /var/run/mountd.pid`),
check the syslog output to see if
.Nm
logged any parsing errors in the exports file.
