nfsconf(8) System Manager's Manual nfsconf(8)
nfsconf - Query various NFS configuration settings
nfsconf --dump [-v|--verbose] [-f|--file infile.conf] [outfile]
nfsconf --entry [--arg subsection] section tag
nfsconf --get [-v|--verbose] [-f|--file infile.conf] [-a|--arg
subsection] section tag
nfsconf --isset [-v|--verbose] [-f|--file infile.conf] [-a|--arg
subsection] section tag
nfsconf --set [-v|--verbose] [-m|--modified Modified by text]
[-f|--file infile.conf] [-a|--arg subsection] section tag value
nfsconf --unset [-v|--verbose] [-f|--file infile.conf] [-a|--arg
subsection] section tag
The nfsconf command can be used to test for and retrieve
configuration settings from a range of nfs-utils configuration
files.
Modes
The following modes are available:
-d, --dump
Output an alphabetically sorted dump of the current
configuration in conf file format. Accepts an optional
filename in which to write the output.
-e, --entry
retrieve the config entry rather than its current expanded
value
-i, --isset
Test if a specific tag has a value set.
-g, --get
Output the current value of the specified tag.
-s, --set
Update or Add a tag and value to the config file in a
specified section, creating the tag, section, and file if
necessary. If the section is defined as '#' then a comment
is appended to the file. If a comment is set with a tag
name then any exiting tagged comment with a matching name
is replaced.
-u, --unset
Remove the specified tag and its value from the config
file.
Options valid in all modes
-v, --verbose
Increase verbosity and print debugging information.
-f, --file infile
Select a different config file to operate upon, default is
/etc/nfs.conf
Options only valid in --entry and --get and --isset modes.
-a, --arg subsection
Select a specific sub-section
Options only valid in --set mode.
-m, --modified "Modified by nfsconf" Set the text on the Modified
date comment in the file. Set to empty to remove.
--isset mode
In this mode the command will return success (0) if the selected
tag has a value, any other exit code indicates the value is not
set, or some other error has occurred.
all other modes
Success is indicated by an exit status of zero, any other status
indicates an error. Error messages are output on stderr, and
increasing verbosity will give more detailed explanations if any
are available.
nfsconf -v --dump --file /tmp/testconf.conf sorted.conf
Check a new config file for syntax errors and output a
sorted version for ease of comparison with existing
settings.
if ! nfsconf --isset gssd preferred-realm ; then echo 'No
preferred realm configured for gss'; fi
The tool allows for easy testing of configuration values
from shell scripts, here we test if a specific value has
been set.
nfsconf --file /etc/nfsmount.conf --get --arg /home MountPoint
background
Show default value for background option for NFS mounts of
the /home path.
nfsconf --file /etc/nfs.conf --set nfsd debug 1
Enable debugging in nfsd
/etc/nfs.conf
nfsd(8), exportfs(8), idmapd(8), statd(8)
