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


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.


EXIT STATUS

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


EXAMPLES

     ``nfsd -n 6'' serves UDP and TCP transports using six threads.
