.SH NAME
rpc.nfsd \- NFS server process
.SH SYNOPSIS
by NFS clients.
.SH OPTIONS
.TP
+.B \-H " or " \-\-host hostname
+specify a particular hostname (or address) that NFS requests will
+be accepted on. By default,
+.B rpc.nfsd
+will accept NFS requests on all known network addresses.
+Note that
+.B lockd
+(which performs file locking services for NFS) may still accept
+request on all known network addresses. This may change in future
+releases of the Linux Kernel.
+.TP
.B \-p " or " \-\-port port
specify a diferent port to listen on for NFS requests. By default,
.B rpc.nfsd
.B rpc.nfsd
can support both NFS version 2,3 and the newer version 4.
.TP
+.B \-T " or " \-\-no-tcp
+Disable
+.B rpc.nfsd
+from accepting TCP connections from clients.
+.TP
+.B \-U " or " \-\-no-udp
+Disable
+.B rpc.nfsd
+from accepting UDP connections from clients.
+.TP
.I nproc
specify the number of NFS server threads. By default, just one
thread is started. However, for optimum performance several threads
the
.BR nfsstat (8)
program.
+.P
+Note that if the NFS server is already running, then the options for
+specifying host, port, and protocol will be ignored. The number of
+processes given will be the only option considered, and the number of
+active
+.B nfsd
+processes will be increased or decreased to match this number.
+In particular
+.B rpc.nfsd 0
+will stop all threads and thus close any open connections.
