NAME
nfs - file containing parameter values for NFS-related daemons
SYNOPSIS
/etc/default/nfs
DESCRIPTION
The nfs file resides in directory
/etc/default and provides startup parameters for the nfsd and
lockd daemons.
The
nfs file format is ASCII; comment lines begin with the crosshatch (
#) character. Parameters consist
of a keyword followed by an equal sign followed by the parameter value. This is the form of parameters
in the file:
keyword=value
The following parameters are currently supported in the
nfs file:
NFS_CLIENT_VERSMIN=
num
NFS_CLIENT_VERSMAX=
num
The NFS client only uses NFS versions in the range specified by these vari-
ables. Valid values or versions are
2, 3, and 4. By default these variables are
unspecified (commented out) and the client’s default minimum is Version 2.
The default maximum is Version 3. You can override this range on a per-
mount basis by using the
-o vers= option to mount_nfs.
NFS_SERVER_VERSMIN=
num
NFS_SERVER_VERSMAX=
num
The NFS server only uses NFS versions in the range specified by these vari-
ables. Valid values or versions are
2, 3, and 4. As with the client, the default
is to leave these variables commented out. The default minimum version is
2,
and the default maximum version is 3.
NFS_SERVER_DELEGATION= on
|off
By default, this variable is commented out and the NFS server provides dele-
gations to clients. The user can turn on delegations for all exported filesys-
tems by setting this variable to on. This variable only applies to NFS Version
4. Delegation should only be turned on provided that there is no local access
to the exported file system.
NFSMAPID_DOMAIN=
domain-string
By default,
nfsmapid uses the DNS domain of the system. This setting over-
rides the default. This domain is used for identifying user and group attribute
strings in the NFS Version 4 protocol. Clients and servers must match with
this domain for operations to proceed normally. This variable only applies to
NFS Version 4. See Setting NFSMAPID_DOMAIN below for further details.
NFSD_MAX_CONNECTIONS=num
Sets the maximum number of concurrent, connection-oriented connections.
The default is unlimited and is obtained by not setting (that is, not comment-
ing out) NFSD_MAX_CONNECTIONS. Equivalent to the -c option in nfsd.
NFSD_LISTEN_BACKLOG=num
Set connection queue length for the NFS over a connection-oriented transport.
The default value is 32, meaning 32 entries in the queue. Equivalent to the
-l option in nfsd.
NFSD_PROTOCOL=ALL Start nfsd over the specified protocol only. Equivalent to the -p option in
nfsd. ALL is equivalent to -a on the nfsd command line. Mutually
exclusive of NFSD_DEVICE. Either NFSD_DEVICE or NFSD_PROTOCOL
must be commented out. For the UDP protocol, only version 2 and version 3
service is established. NFS Version 4 is not supported for the UDP protocol.
