NFSD(8) 						    BSD System Manager's Manual 						   NFSD(8)

NAME

     nfsd -- remote NFS server

SYNOPSIS

     nfsd [-6rut] [-n num_threads]

DESCRIPTION

     nfsd runs on a server machine to service NFS requests from client machines.  At least one nfsd must be running for a machine to operate as a
     server.

     Unless otherwise specified, four servers for UDP transport are started.

     The following options are available:

     -r      Register the NFS service with rpcbind(8) without creating any servers.  This option can be used along with the -u or -t options to
	     re-register NFS if the portmap server is restarted.

     -n      Specifies how many server threads to create.  The default is 4.  A server should run enough threads to handle the maximum level of
	     concurrency from its clients.

     -6      Listen to IPv6 requests as well as IPv4 requests. If IPv6 support is not available, nfsd will silently continue and just use IPv4.

     -t      Serve TCP NFS clients.

     -u      Serve UDP NFS clients.

     For example, ``nfsd -t -u -n 6'' serves UDP and TCP transports using six threads.

     nfsd listens for service requests at the port indicated in the NFS server specification; see Network File System Protocol Specification, RFC
     1094 and NFS: Network File System Version 3 Protocol Specification.

     The nfsd utility exits 0 on success, and >0 if an error occurs.
