.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:
|
||
|
|
.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
|
||
|
|
.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.
|
||
|
|
.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
|
||
|
|
.Tn UDP
|
||
|
|
and
|
||
|
|
.Tn TCP
|
||
|
|
transports using six daemons.
|
||
|
|
.Pp
|
||
|
|
A server should run enough daemons to handle
|
||
|
|
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.

|
||
|

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