NAME

6       rpc.nfsd - NFS server process
7

SYNOPSIS

9       /usr/sbin/rpc.nfsd [options] nproc
10

DESCRIPTION

12       The rpc.nfsd program implements the user level part of the NFS service.
13       The main functionality is handled by the nfsd.o kernel module; the user
14       space program merely starts the specified number of kernel threads.
15
16       The  rpc.mountd  server provides an ancillary service needed to satisfy
17       mount requests by NFS clients.
18

OPTIONS

20       -H  or  --host hostname
21              specify a particular hostname (or  address)  that  NFS  requests
22              will  be  accepted  on.  By  default,  rpc.nfsd  will accept NFS
23              requests on all known network addresses.  Note that lockd (which
24              performs file locking services for NFS) may still accept request
25              on all known network  addresses.   This  may  change  in  future
26              releases of the Linux Kernel.
27
28       -p  or  --port port
29              specify  a  diferent  port  to  listen  on  for NFS requests. By
30              default, rpc.nfsd will listen on port 2049.
31
32       -N  or  --no-nfs-version vers
33              This option can be used to request that rpc.nfsd does not  offer
34              certain  versions  of  NFS.  The current version of rpc.nfsd can
35              support both NFS version 2,3 and the newer version 4.
36
37       -T  or  --no-tcp
38              Disable rpc.nfsd from accepting TCP connections from clients.
39
40       -U  or  --no-udp
41              Disable rpc.nfsd from accepting UDP connections from clients.
42
43       nproc  specify the number of NFS server threads. By default,  just  one
44              thread  is  started.  However,  for  optimum performance several
45              threads should be used. The actual figure depends on the  number
46              of  and  the  work load created by the NFS clients, but a useful
47              starting point is 8 threads. Effects of  modifying  that  number
48              can be checked using the nfsstat(8) program.
49
50       Note  that  if  the NFS server is already running, then the options for
51       specifying host, port, and protocol will be  ignored.   The  number  of
52       processes  given  will be the only option considered, and the number of
53       active nfsd processes will be increased or decreased to match this num‐
54       ber.  In particular rpc.nfsd 0 will stop all threads and thus close any
55       open connections.
