NAME

  mountd - Services remote NFS compatible mount	requests

SYNOPSIS

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

OPTIONS

  -a  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.

  -d  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.

  -n  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 option	to
      allow non-root mount requests.

  -i  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.

  -r  Listens for requests on a	reserved port only.  This is the default
      behavior.

  -R  Enables listening	for requests on	an unreserved port.

  -s  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	sys-
  tems to mount	directories. When it receives a	SIGHUP signal, the mountd
  daemon rereads the exports file.

  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 giga-
  bytes.  However, they	appear as 2 gigabyte partitions	when viewed from NFS
  clients.
