.Sh NAME
.Nm nfsd
.Nd remote
.Tn NFS
server
.Sh SYNOPSIS
.Nm nfsd
.Op Fl rut
.Op Fl n Ar num_servers
1993-03-21 12:45:37 +03:00
.Sh DESCRIPTION
.Nm Nfsd
runs on a server machine to service
.Tn NFS
requests from client machines.
At least one
.Nm nfsd
must be running for a machine to operate as a server.
.Pp
Unless otherwise specified, four servers for
.Tn UDP
transport are started.
.Pp
The following options are available:
1993-03-21 12:45:37 +03:00
.Bl -tag -width Ds
.It Fl r
Register the
.Tn NFS
service with
.Xr portmap 8
without creating any servers.
This option can be used along with the
1993-03-21 12:45:37 +03:00
.Fl u
or
.Fl t
options to re-register NFS if the portmap server is restarted.
.It Fl n
Specifies how many servers to create.
1993-03-21 12:45:37 +03:00
.It Fl t
Serve
.Tn TCP NFS
clients.
.It Fl u
Serve
.Tn UDP NFS
clients.
.El
.Pp
For example,
.Dq Li "nfsd -u -t 6"
serves
1993-03-21 12:45:37 +03:00
.Tn UDP
and
.Tn TCP
transports using six daemons.
1993-03-21 12:45:37 +03:00
.Pp
A server should run enough daemons to handle
1993-03-21 12:45:37 +03:00
the maximum level of concurrency from its clients,
typically four to six.
.Pp
.Nm Nfsd
listens for service requests at the port indicated in the
.Tn NFS
server specification; see
.%T "Network File System Protocol Specification" ,
RFC1094.
.Pp
The
.Nm nfsd
utility exits 0 on success, and >0 if an error occurs.
