MOUNTD(8) BSD System Manager's Manual MOUNTD(8)
mountd -- service remote NFS mount requests
mountd [-dN] [-P policy] [-p port] [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, RFC 1094, Appendix A and NFS: Network File System Version 3
Protocol Specification, Appendix I.
Options and operands available for mountd:
-d Enable debugging mode. mountd will not detach from the controlling terminal and
will print debugging messages to stderr.
-N Do not require privileged ports for mount or NFS RPC calls. This option is equiva-
lent to specifying ``-noresvport -noresvmnt'' on every export. See exports(5) for
more information. Some operating systems (notably Mac OS X) require this option.
IPsec policy string, as described in 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 mountd logs an error message and terminates itself.
Force mountd to bind to the given port. If this option is not given, mountd may
bind to every anonymous port (in the range 600-1023) which causes trouble when try-
ing to use NFS through a firewall.
The exportsfile argument specifies an alternative location for the exports file.
When mountd is started, it loads the export host addresses and options into the kernel using
the nfssvc(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.
After receiving SIGTERM, mountd 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
/etc/exports the list of exported filesystems
/var/run/mountd.pid the pid of the currently running mountd
/var/db/mountdtab the list of remotely mounted filesystems
nfsstat(1), nfssvc(2), exports(5), nfsd(8), rpcbind(8), showmount(8)
The mountd utility first appeared in 4.4BSD.
