NAME

       nfsd - NFS daemon

SYNOPSIS

       #_conn] listen_backlog] protocol] device] [nservers]

DESCRIPTION

       is the daemon that handles client file system requests.	Only users with sufficient privileges can run this daemon.

       The daemon is automatically invoked if and in the file.

       By  default,  starts  over the TCP and UDP transports for version 2 and version 3, and over TCP for version 4, if NFS version 4 is enabled.
       One can change this with the option.

       A previously invoked daemon started with or without options must be stopped before invoking another command.

       Administrators wanting to change startup parameters for should make changes (as root user) to the NFS default file (see nfs(4)).   Adminis-
       trators can either edit this file or use the command to make changes.

   Options
       The following options are supported:
	      Start  a NFS daemon over all available connectionless and connection-oriented transports, including UDP and TCP.	Equivalent to set-
	      ting the parameter to in the NFS default file.

	      This sets the maximum number of connections allowed to the NFS
		     server over connection-oriented transports.  By default, the number of connections is unlimited.  Equivalent to the parameter
		     in the NFS default file.

	      Set connection
		     queue  length  for  the  NFS  TCP	over a connection-oriented transport.  The default value is 32 entries.  Equivalent to the
		     parameter in the NFS default file.

	      Start a NFS daemon over the specified protocol.
		     Equivalent to the parameter in the NFS default file.

	      Start a NFS daemon for the transport specified by the given device.
		     Equivalent to the parameter in the NFS default file.

   Operands
       The following operands are supported:
	      This sets the maximum number of concurrent NFS requests that the server can handle.  This concurrency is achieved by up to  nservers
	      threads  created	as needed in the kernel.  nservers should be based on the load expected on this server.  16 is the usual number of
	      nservers.  If nservers is not specified, the maximum number of concurrent NFS requests will default to 1.   Changing  the  value	of
	      nservers requires stopping and restarting Equivalent to the parameter in the NFS default file.

   Notes
       A directory service that provides service name data base support must have the following service entries in its database:

       If  the	kernel	tunable  (see  nfs_portmon(5)) is set to 1, then clients are required to use privileged ports (ports < IPPORT_RESERVED) to
       receive NFS services.  This tunable is set to 0 by default.  Use (see kctune(1M)) to set this tunable.

       By default, the NFS version 4 server is disabled. In order to enable it you must stop the NFS server.  As root, either use the command (see
       setoncenv(1M)) or edit to set the parameter to 4.

EXIT STATUS

       Daemon started successfully.
       Daemon failed to start.

WARNINGS

       Manually starting and restarting is not recommended.  If it is necessary to do so, use the NFS server start/stop script

FILES

       client machine pointer to an open-but-unlinked file.

       shell script for starting

       startup parameters for

       directories used by the server to manage client state
	      information; these directories should not be removed.
