NAMED-JOURNALPRINT(8)

NAME
named-journalprint - print zone journal in human-readable form

SYNOPSIS

named-journalprint [-dux] {journal}

DESCRIPTION

named-journalprint scans the contents of a zone journal file, printing it in a human-readable form, or, optionally, converting it to a different journal file format.

Journal files are automatically created by named when changes are made to dynamic zones (e.g., by nsupdate). They record each addition or deletion of a resource record, in binary format, allowing the changes to be re-applied to the zone when the server is restarted after a shutdown or crash. By default, the name of the journal file is formed by appending the extension .jnl to the name of the corresponding zone file.

named-journalprint converts the contents of a given journal file into a human-readable text format. Each line begins with add or del, to indicate whether the record was added or deleted, and continues with the resource record in master-file format.

The -x option causes additional data about the journal file to be printed at the beginning of the output and before each group of changes.

The -u (upgrade) and -d (downgrade) options recreate the journal file with a modified format version. The existing journal file is replaced. -d writes out the journal in the format used by versions of BIND up to 9.16.11; -u writes it out in the format used by versions since 9.16.13. (9.16.12 is omitted due to a journal-formatting bug in that release.) Note that these options must not be used while named is running.
