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.o 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 net-
              work 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 ver-
              sions 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.
