7 rpc.nfsd \- NFS server process
9 .BI "/usr/sbin/rpc.nfsd [" options "]" " "nproc
13 program implements the user level part of the NFS service. The
14 main functionality is handled by the
16 kernel module; the user space program merely starts the specified
17 number of kernel threads.
21 server provides an ancillary service needed to satisfy mount requests
25 .B \-H " or " \-\-host hostname
26 specify a particular hostname (or address) that NFS requests will
27 be accepted on. By default,
29 will accept NFS requests on all known network addresses.
32 (which performs file locking services for NFS) may still accept
33 request on all known network addresses. This may change in future
34 releases of the Linux Kernel.
36 .B \-p " or " \-\-port port
37 specify a diferent port to listen on for NFS requests. By default,
39 will listen on port 2049.
41 .B \-N " or " \-\-no-nfs-version vers
42 This option can be used to request that
44 does not offer certain versions of NFS. The current version of
46 can support both NFS version 2,3 and the newer version 4.
48 .B \-T " or " \-\-no-tcp
51 from accepting TCP connections from clients.
53 .B \-U " or " \-\-no-udp
56 from accepting UDP connections from clients.
59 specify the number of NFS server threads. By default, just one
60 thread is started. However, for optimum performance several threads
61 should be used. The actual figure depends on the number of and the work
62 load created by the NFS clients, but a useful starting point is
63 8 threads. Effects of modifying that number can be checked using
68 Note that if the NFS server is already running, then the options for
69 specifying host, port, and protocol will be ignored. The number of
70 processes given will be the only option considered, and the number of
73 processes will be increased or decreased to match this number.
76 will stop all threads and thus close any open connections.
