MOUNTD(8) BSD System Manager's Manual MOUNTD(8)NAMEmountd — service remote NFS mount requests
/sbin/mountd [-nr] [exportsfile]
Mountd is the server for NFS mount requests from other client machines.
Mountd listens for service requests at the port indicated in the NFS
server specification; see Network File System Protocol Specification,
RFC1094, Appendix A and NFS: Network File System Version 3 Protocol
Specification, Appendix I.
Options and operands available for mountd:
-n The -n option allows non-root mount requests to be served. This
should only be specified if there are clients such as PC's, that
-r The -r option allows mount RPCs requests for regular files to be
served. Although this seems to violate the mount protocol speci‐
fication, some diskless workstations do mount requests for their
swapfiles and expect them to be regular files. Since a regular
file cannot be specified in /etc/exports, the entire file system
in which the swapfiles resides will have to be exported with the

When mountd 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 mountd 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 mountd
logged any parsing errors in the exports file.
/etc/exports the list of exported filesystems
/var/run/mountd.pid the pid of the currently running mountdSEE ALSOnfsstat(1), exports(5), nfsd(8), portmap(8), showmount(8)HISTORY
