NAME

	tozone – convert ndb database to a zone file

SYNOPSIS

	ndb/tozone [ –dg ] [ –f dbfile ] [ zone... ]

DESCRIPTION

Convert a network database file to a zone file for bind interoperability. Standard name compression is applied and glue for subordinate zones is automaticly generated. (Glue may be supressed with –g). Each soa in the input file (default /lib/ndb/local) is converted into a zone. Reverse zones (including classless RFC2317–style zones) are automaticly generated given an soa record. The databases may be specified with the –f flag. Arguments limit the zones generated to the specified zones.

FILES

BUGS

	Ndb's structure makes it difficult to be precise about which records belong to which zones. In contrast to a `/' in a path, a `.' in a dns name is not always a zone boundary. Zones are greedy; a single soa with a dom of `.' would include all names.
