The last is the number of concurrent mounts that we believe the client
has of that path.
.TP
-.BI "\-P," "" " \-\-state\-directory\-path " directory
+.BI "\-s," "" " \-\-state\-directory\-path " directory
specify a directory in which to place statd state information.
If this option is not specified the default of
.BR /var/lib/nfs
is used.
.TP
+.BI "\-r," "" " \-\-reverse\-lookup"
+mountd tracks IP addresses in the rmtab, and when a DUMP request is made (by
+someone running showmount -a, for instance), it returns IP addresses instead
+of hostnames by default. This option causes mountd to do a reverse
+lookup on each IP address and return that hostname instead. Enabling this can
+have a substantial negative effect on performance in some situations.
+.TP
.BR "\-t N" " or " "\-\-num\-threads=N"
This option specifies the number of worker threads that rpc.mountd
spawns. The default is 1 thread, which is probably enough. More
You have to use the daemon name
.B mountd
for the daemon name (even if the binary has a different name).
+.B Note:
+hostnames used in either access file will be ignored when
+they can not be resolved into IP addresses.
For further information please have a look at the
.BR tcpd (8)
and
.BR hosts_access (5)
manual pages.
