This option can be used along with the 45.Fl u 46or 47.Fl t 48options to re-register NFS if the portmap server is restarted. 49.It Fl t 50Serve 51.Tn TCP NFS 52clients. 53.It Fl u 54Serve 55.Tn UDP NFS 56clients. 57.It Ar numprocs 58Specifies how many servers to fork off. 59.El 60.Pp 61If neither 62.Fl u 63or 64.Fl t 65are specified, 66.Ar numprocs 67servers for 68.Tn UDP 69transport are started. (compatibility) 70If 71.Ar numprocs 72is not specified, it defaults to 4. 73.Pp 74For example: 75.Bd -literal 76nfsd \-u \-t 6 77.Ed 78.Bl -item -offset indent 79.It 80Serves 81.Tn UDP 82and 83.Tn TCP 84transports using 6 daemons in the kernel. 85.Pp 86A server should typically run enough daemons to handle 87the maximum level of concurrency from its clients, 88typically four to six. 89.Pp 90.Nm Nfsd 91listens for service requests at the port indicated in the 92.Tn NFS 93server specification; see 94.%T "Network File System Protocol Specification" , 95RFC1094. 96.Sh SEE ALSO 97.Xr nfsstat 1 , 98.Xr nfssvc 2 , 99.Xr mountd 8 , 100.Xr portmap 8 101.Sh HISTORY 102The 103.Nm nfsd 104utility first appeared in 4.4BSD. 105
