.Sh DESCRIPTION
|
|
.Nm
|
|
is the server for
|
|
.Tn NFS
|
|
mount requests from other client machines.
|
|
.Nm
|
|
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.

|
|
IPsec
|
|
.Ar policy
|
|
string,
|
|
as described in
|
|
.Xr ipsec_set_policy 3 .
|
|
Multiple IPsec policy strings may be specified by using a semicolon as
|
|
a separator. If conflicting policy strings are found in a single line,
|
|
the last string will take effect. If an invalid IPsec policy string is used
|
|
.Nm
|
|
logs an error message and terminates itself.
|
|
.It Fl d
|
|
Enable debugging mode.
|
|
.Nm
|
|
will not detach from the controlling terminal and will print
|
|
debugging messages to stderr.
|
|
.It Fl n
|
|
This flag used to indicate that clients were required to make requests
|
|
from reserved ports, but it is now no longer functional. It
|
|
is only provided for backwards compatibility. Requests
|
|
are checked for reserved ports on a per-export basis, see
|
|
.Xr exports 5 .
|
|
.It Ar exportsfile
|
|
The
|
|
.Ar exportsfile
|
|
argument specifies an alternative location
|
|
for the exports file.
|
|
.El
|
|
.Pp
|
|
When
|
|
.Nm
|
|
is started,
|
|
it loads the export host addresses and options into the kernel
|
|
using the
|
|
.Xr 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.
|
|
.Pp
|
|
After receiving SIGTERM,
|
|
.Nm
|
|
sends a broadcast request to remove the mount list from all the clients.
|
|
This can take a long time, since the broadcast request waits for each
|
|
client to respond.
