# NAME

nfsd — remote NFS server

# SYNOPSIS

nfsd | [-46drut] [-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:

-d
  Turn on debugging, don't fork and log to stderr.
-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.
-4
  Only listen to IPv4 requests. By default nfsd listens to both IPv6 and IPv4 and tries to register for both.
-6
  Only listen to IPv6 requests.
-t
  Serve only TCP NFS clients. By default nfsd serves both TCP NFS and UDP NFS clients
-u
  Serve only UDP NFS clients.

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.
