rpc.nfsd(8)							   rpc.nfsd(8)

NAME
       rpc.nfsd - NFS server process

SYNOPSIS
       /usr/sbin/rpc.nfsd [options] nproc

DESCRIPTION
       The rpc.nfsd program implements the user level part of the NFS service.
       The main functionality is handled by the nfsd kernel module.  The  user
       space  program merely specifies what sort of sockets the kernel service
       should listen on, what NFS versions it should  support,	and  how  many
       kernel threads it should use.

       The  rpc.mountd	server provides an ancillary service needed to satisfy
       mount requests by NFS clients.

OPTIONS
       -d  or  --debug
	      enable logging of debugging messages

       -H  or  --host hostname
	      specify a particular hostname (or	 address)  that	 NFS  requests
	      will  be	accepted  on.  By  default,  rpc.nfsd  will accept NFS
	      requests on all known network addresses.	Note that lockd (which
	      performs file locking services for NFS) may still accept request
	      on all known network  addresses.	 This  may  change  in	future
	      releases of the Linux Kernel.

       -p  or  --port port
	      specify  a  different  port  to  listen  on for NFS requests. By
	      default, rpc.nfsd will listen on port 2049.

       -N  or  --no-nfs-version vers
	      This option can be used to request that rpc.nfsd does not	 offer
	      certain  versions	 of  NFS.  The current version of rpc.nfsd can
	      support NFS versions 2,3,4 and the newer version 4.1.

       -s  or  --syslog
	      By default, rpc.nfsd logs error messages (and debug messages, if
	      enabled)	to  stderr.  This option makes rpc.nfsd log these mes‐
	      sages to syslog instead. Note  that  errors  encountered	during
	      option  processing  will still be logged to stderr regardless of
	      this option.

       -T  or  --no-tcp
	      Disable rpc.nfsd from accepting TCP connections from clients.

       -U  or  --no-udp
	      Disable rpc.nfsd from accepting UDP connections from clients.

       -V  or  --nfs-version vers
	      This option can be used to request that rpc.nfsd	offer  certain
	      versions of NFS. The current version of rpc.nfsd can support NFS
	      versions 2,3,4 and the newer version 4.1.

       nproc  specify the number of NFS server threads. By default,  just  one
	      thread  is  started.  However,  for  optimum performance several
	      threads should be used. The actual figure depends on the	number
	      of  and  the  work load created by the NFS clients, but a useful
	      starting point is 8 threads. Effects of  modifying  that	number
	      can be checked using the nfsstat(8) program.

       Note  that  if  the NFS server is already running, then the options for
       specifying host, port, and protocol will be  ignored.   The  number  of
       processes  given	 will be the only option considered, and the number of
       active nfsd processes will be increased or decreased to match this num‐
       ber.  In particular rpc.nfsd 0 will stop all threads and thus close any
       open connections.

NOTES
       If the program is built with TI-RPC support, it will enable any	proto‐
       col and address family combinations that are marked visible in the net‐
       config database.
