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
  systems 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
  gigabytes.  However, they appear as 2 gigabyte partitions when viewed from
  NFS clients.
