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.

HISTORY
     The nfsd utility first appeared in 4.4BSD.
