# NAME

`nfsd` — remote NFS server

# SYNOPSIS

`nfsd` | [`-rtu`] [`-n` num_servers]

# 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 options are as follows:

`-n` num_servers
  Specifies how many servers to create (max 20).
`-r`
  Register the NFS service with portmap(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.
`-t`
  Serve TCP NFS clients.
`-u`
  Serve UDP NFS clients.

For example, “`nfsd -u -t -n 6`” serves UDP and TCP transports using six daemons.

A server should run enough daemons to handle the maximum level of concurrency from its clients, typically four to six.

`nfsd` listens for service requests at the port indicated in the NFS server specification; see RFCs 1094 and 1813.

# EXIT STATUS
