50 runs on a server machine to service
52 requests from client machines.
55 must be running for a machine to operate as a server.
57 Unless otherwise specified, four servers for
59 transport are started.
61 The following options are available:
68 without creating any servers.
69 This option can be used along with the
73 options to re-register NFS if the rpcbind server is restarted.
79 without creating any servers.
81 Specifies how many servers to create.
83 Specifies which IP address or hostname to bind to on the local host.
84 This option is recommended when a host has multiple interfaces.
87 options may be specified.
89 Specifies that nfsd should bind to the wildcard IP address.
90 This is the default if no
92 options are given. It may also be specified in addition to any
94 options given. Note that NFS/UDP does not operate properly when
95 bound to the wildcard IP address whether you use -a or do not use -h.

112 transports using six daemons.
114 A server should run enough daemons to handle
115 the maximum level of concurrency from its clients,
116 typically four to six.
119 listens for service requests at the port indicated in the
121 server specification; see
122 .%T "Network File System Protocol Specification" ,

148 option is recommended. If you do not use the option NFS may not respond to
149 UDP packets from the same IP address they were sent to. Use of this option
150 is also recommended when securing NFS exports on a firewalling machine such
151 that the NFS sockets can only be accessed by the inside interface.
