NAME
nfsd — remote NFS server
SYNOPSIS
nfsd |
[-46rut] [-n num_threads] |
DESCRIPTION
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.
Unless otherwise specified, four servers for UDP transport are started.
The following options are available:
-
-r
-
Register the NFS service with rpcbind(8) without creating any servers. This option can be used along with the -u or -t options to re-register NFS if the portmap server is restarted.
-
-n
-
Specifies how many server threads to create. The default is 4. A server should run enough threads to handle the maximum level of concurrency from its clients.
-
-4
-
Only listen to IPv4 requests. By default nfsd listens to both IPv6 and IPv4 and tries to register for both.
-
-6
-
Only listen to IPv6 requests.
-
-t
-
Serve only TCP NFS clients. By default nfsd serves both TCP NFS and UDP NFS clients
-
-u
-
Serve only UDP NFS clients.
nfsd listens for service requests at the port indicated in the NFS server specification; see Network File System Protocol Specification, RFC 1094 and NFS: Network File System Version 3 Protocol Specification.
EXIT STATUS
The nfsd utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
“nfsd -n 6
” serves UDP and TCP transports using six threads.
HISTORY
The nfsd utility first appeared in 4.4BSD.
