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 starts the specified number of kernel threads.

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

OPTIONS

       -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  diferent  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 both NFS version 2,3 and the newer version 4.

       -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.

       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
       number.   In particular rpc.nfsd 0 will stop all threads and thus close
       any open connections.
