If an invalid IPsec policy string is used 71.Nm 72logs an error message and terminates itself. 73.It Fl d 74Enable debugging mode. 75.Nm 76will not detach from the controlling terminal and will print 77debugging messages to stderr. 78.It Fl n 79This flag used to indicate that clients were required to make requests 80from reserved ports, but it is now no longer functional. It 81is only provided for backwards compatibility. Requests 82are checked for reserved ports on a per-export basis, see 83.Xr exports 5 . 84.It Ar exportsfile 85The 86.Ar exportsfile 87argument specifies an alternative location 88for the exports file. 89.El 90.Pp 91When 92.Nm 93is started, 94it loads the export host addresses and options into the kernel 95using the 96.Xr mount 2 97system call. 98After changing the exports file, 99a hangup signal should be sent to the 100.Nm 101daemon to get it to reload the export information. 102After sending the SIGHUP 103(kill \-s HUP `cat /var/run/mountd.pid`), 104check the syslog output to see if 105.Nm 106logged any parsing errors in the exports file. 107.Pp 108After receiving SIGTERM, 109.Nm 110sends a broadcast request to remove the mount list from all the clients. 111This can take a long time, since the broadcast request waits for each 112client to respond. 113.Sh FILES 114.Bl -tag -width /var/run/mountd.pid -compact 115.It Pa /etc/exports 116the list of exported filesystems 117.It Pa /var/run/mountd.pid 118the pid of the currently running 119.Nm 120.El 121.Sh SEE ALSO 122.Xr nfsstat 1 , 123.Xr exports 5 , 124.Xr nfsd 8 , 125.Xr rpcbind 8 , 126.Xr showmount 8 127.Sh HISTORY 128The 129.Nm 130utility first appeared in 131.Bx 4.4 . 132
