nsd-checkconf

nsd-checkconf(8)						    nsd 3.2.12							  nsd-checkconf(8)

NAME

       nsd-checkconf - NSD configuration file checker.

SYNOPSIS

       nsd-checkconf [-v] [-h] [-o option] [-z zonename] [-s keyname] configfile

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).

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

OPTIONS

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

       -h     Print usage help information and exit.

       -o option
	      Return only this option from the config file. This option can to be used in conjunction with the -z option.  The special value zones
	      prints out a list of configured zones.

	      This  option  is primarily used by nsdc 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
	      Prints the key secret (base64 blob) configured for this key in the config file. Used to help shell scripts parse the config file.

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

	      If this option is not given, the server section of the config file is used.  This option is primarily used by nsdc to parse the con-
	      fig file from the shell.

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

FILES

       /etc/nsd3/nsd.conf
	      default NSD configuration file
