47 utility is the server for
49 mount requests from other client machines.
50 It listens for service requests at the port indicated in the
52 server specification; see
53 .%T "Network File System Protocol Specification" ,
54 RFC1094, Appendix A and
55 .%T "NFS: Network File System Version 3 Protocol Specification" ,
58 The following options are available:
59 .Bl -tag -width indent
61 Allow the administrator to force clients to use only the
64 protocol to mount file systems from this server.
66 Output debugging information.
70 requests to be logged.
72 Allow non-root mount requests to be served.
73 This should only be specified if there are clients such as PC's,
75 It will automatically clear the vfs.nfsrv.nfs_privport sysctl flag, which
76 controls if the kernel will accept NFS requests from reserved ports only.
80 to bind to the specified port, for both
85 This is typically done to ensure that the port which
87 binds to is a known quantity which can be used in firewall rulesets.
90 cannot bind to this port, an appropriate error will be recorded in
91 the system log, and the daemon will then exit.
93 Allow mount RPCs requests for regular files to be served.
94 Although this seems to violate the mount protocol specification,
95 some diskless workstations do mount requests for
96 their swapfiles and expect them to be regular files.
97 Since a regular file cannot be specified in
99 the entire file system in which the swapfiles resides
100 will have to be exported with the
