nfsd(8)

NAME

     nfsd -- remote NFS server

SYNOPSIS

     nfsd [-ardut] [-n num_servers] [-h bindip]

DESCRIPTION

     The nfsd utility 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 rpcbind server is restarted.

     -d      Unregister the NFS service with rpcbind(8) without creating any
	     servers.

     -n      Specifies how many servers to create.

     -h bindip
	     Specifies which IP address or hostname to bind to on the local
	     host.  This option is recommended when a host has multiple inter-
	     faces.  Multiple -h options may be specified.

     -a      Specifies that nfsd should bind to the wildcard IP address.  This
	     is the default if no -h options are given.  It may also be speci-
	     fied in addition to any -h options given.	Note that NFS/UDP does
	     not operate properly when bound to the wildcard IP address
	     whether you use -a or do not use -h.

     -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 concur-
     rency from its clients, typically four to six.

     The nfsd utility listens for service requests at the port indicated in
     the NFS server specification; see Network File System Protocol
     Specification, RFC1094 and NFS: Network File System Version 3 Protocol
     Specification.

     If nfsd detects that NFS is not loaded in the running kernel, it will
     attempt to load a loadable kernel module containing NFS support using
     kldload(2).  If this fails, or no NFS KLD is available, nfsd will exit
     with an error.

     If nfsd is to be run on a host with multiple interfaces or interface
     aliases, use of the -h option is recommended.  If you do not use the
     in order to stay alive as long as possible during a shutdown, otherwise
     loopback mounts will not be able to unmount.  If you have to kill nfsd
     just do a ``kill -USR1 <PID of master nfsd>''

DIAGNOSTICS

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