NAME

     mountd -- service remote NFS mount requests

SYNOPSIS

     mountd [-dN] [-P policy] [-p port] [exportsfile]

DESCRIPTION

     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 equivalent to specifying ``-noresvport -noresvmnt'' on
	     every export.  See exports(5) for more information.  Some operating systems (notably Mac OS X) require this option.

     -P policy
	     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.

     -p port
	     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 trying to use NFS through a firewall.

     exportsfile
	     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 to respond.

FILES

     /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

NAME

       mountd - Services remote NFS compatible mount requests

SYNOPSIS

       mountd [-d] [-i] [-n] [-s] [exportsfile]

FLAGS

       Verifies the Internet addresses of hosts that make mount and unmount requests.  If a client's address cannot be translated into a host name
       by the gethostbyaddr() function and then translated back into the same Internet address by the gethostbyname()  function,  the  request	is
       rejected.

	      This  option  requires  the  BIND service for Internet address resolution.  It offers the highest level of security, especially when
	      combined with the -i option.  Turns on Internet address verification and domain checking.  If you  are  running  the  BIND  service,
	      mountd  verifies	that  a  host  making  a mount or unmount request is in the server's domain.  Allows non-root mount requests to be
	      served.  This should only be specified if there are clients such as PC's that require it.  ULTRIX  BSD  is  allowed  non-root  mount
	      requests	by default.  Use the -n flag to allow non-root mount requests.	Verifies the Internet address of hosts that make mount and
	      unmount requests.  If a client's address cannot be translated into a host name by  the  gethostbyaddr()  function,  the  request	is
	      rejected.   If  you  are running the BIND service, the BIND server is used to translate the address.  If you are not, the /etc/hosts
	      file is used.

	      If the -i option is not used and a client's address cannot be translated,  the  address  is  converted  to  a  string  of  the  form
	      xx.xx.xx.xx.  This allows access to exported file systems that do not specify a list of allowed hostnames.

	      The -i option is automatically enabled when either the -d or the -s option is specified.	Turns on Internet address verification and
	      subdomain checking.  If you are running the BIND service, mountd verifies that a host making a mount or unmount request  is  in  the
	      server's domain or subdomain.

DESCRIPTION

       The  mountd daemon is the server for NFS protocol mount requests from clients.  The mountd daemon responds to requests from remote computer
       systems to mount directories.  When it receives a SIGHUP signal, mountd rereads the exports file.  If you are on an NFS client and want	to
       have  changes  to  the export options on existing NFS client mounts take effect immediately, issue the showmount -e command and specify the
       name of the host that is exporting the directory or file system (where the exports file is located).  This ensures that NFS is aware of the
       export list and options.

       The optional exportsfile argument specifies an alternate location for the exports file.	/etc/exports is the default.

       Note,  NFS  Version  2  can export partitions that are greater than 2 gigabytes.  However, they appear as 2 gigabyte partitions when viewed
       from NFS clients.
