# mydnscheck(8)

Check zone data for consistency and syntax.

## NAME

mydnscheck - Check zone data for consistency and syntax.

## SYNOPSIS

**mydnscheck** \[**-c**, **--consistency**\] \[**-C**, **--consistency-only**\] \[**-D**, **--database=***dbname*\] \[**-h**, **--host=***hostname*\] \[**-p**, **--password\[=***password*\]\] \[**-u**, **--user=***username*\] \[**-v**, **--verbose**\] \[**--help**\] \[**--version**\] \[**ZONE**...\]

## DESCRIPTION

**mydnscheck** scans the zones named on the command line for syntax.  If no zones are specified, all zones are scanned.  If the -c (or -C) option is specified, additional database consistency checks are performed. The program writes all results to stdout in a format that both humans and computers should be able to read.  Each problem found is listed on a separate line, with a TAB character in between each field. The fields listed are: **MESSAGE** .. **SOA ID** .. **RR ID** .. **NAME** .. **TTL** .. **TYPE** .. **DATA** If stderr is a terminal, a progress meter is displayed if scanning all zones.
