# [NAME](#NAME)

**nsd-checkconf** - NSD configuration file checker.

# [SYNOPSIS](#SYNOPSIS)

**nsd-checkconf** \[**-v**] \[**-f**] \[**-h**] \[**-o** *option*] \[**-z** *zonename*] \[**-p** *pattern*] \[**-s** *keyname*] \[**-t** *tlsauthname*] *configfile*

# [DESCRIPTION](#DESCRIPTION)

**nsd-checkconf** reads a configuration file. It prints parse errors to standard error, and performs additional checks on the contents. The configfile format is described in [nsd.conf(5)](/man/os/nsd/nsd.conf.5).

The utility of this program is to check a config file for errors before using it in [nsd(8)](/man/os/nsd/nsd.8). This program can also be used for shell scripts to access the nsd config file, using the -o and -z options.

# [OPTIONS](#OPTIONS)

[**-v**](#v)

After reading print the options to standard output in configfile format. Without this option, only success or parse errors are reported.

[**-f**](#f)

Print full pathname when used with files, like with -o pidfile. This includes the chroot in the way it is applied to the pidfile.

[**-h**](#h)

Print usage help information and exit.

[**-o *option***](#o)

Return only this option from the config file. This option can be used in conjunction with the **-z** and the **-p** option, or without them to query the server: section. The special value *zones* prints out a list of configured zones. The special value *patterns* prints out a list of configured patterns.

This option can be used to parse the config file from the shell. If the **-z** option is given, but the **-o** option is not given, nothing is printed.

[**-s *keyname***](#s)

Prints the key secret (base64 blob) configured for this key in the config file. Used to help shell scripts parse the config file.

[**-t *tls-auth***](#t)

Prints the authentication domain name configured for this tls-auth clause in the config file. Used to help shell scripts parse the config file.

[**-p *pattern***](#p)

Return the option specified with **-o** for the given pattern name.

[**-z *zonename***](#z)

Return the option specified with **-o** for zone 'zonename'.

If this option is not given, the server section of the config file is used.

The -o, -s and -z option print configfile options to standard output.
