C 7 nfsd - remote NFS server /sbin/nfsd [ numdaemons [ filtermask filtervalue ] ] Nfsd 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. The option numdaemons defines how many nfsd daemons to start; if unspecified, only a single daemon will be started. A server should typically run enough daemons to handle the maximum level of concurrency from its clients, typically four to six.

The options filtermask and filtervalue may be specified to restrict the clients serviced by filtering incoming source addresses. They are expressed in Internet standard "." notation. The algorithm is simply:

The default values for filtermask and filtervalue are 0, which accepts requests from all client source_addr's. Alternately, the most secure values you could use for filtermask and filtervalue would be: although your subnet or net number and mask will be just as good in most cases.

Nfsd listens for service requests at the port indicated in the NFS server specification; see ``Network File System Protocol Specification, RFC1094''
