dns_tree [-f] [-v] [-d] [-t TYPE] [-m MATCH] DNS_domain
This manual page documents briefly the dns_tree command.
This manual page was written for the Debian distribution
because the original program does not have a manual page.
dns_tree is a program that works as a front-end
to dig. Given a specific domain
dns_tree will make several dig invocations to fetch a zone and it will format the output in in a somewhat
sensible hierarchical style (a tree).
Information extracted from the DNS relies on being possible to fetch a zone through a zone transfer. If the DNS servers for the requested domain do not allow file transfers dns_tree will not be able to obtain information from the zone.
All data obtain is cached in ~/.DNS_BROWSE with an approximation of
the usual DNS caching rules. Remove all files in that directory to
prematurely flush the cache.
A summary of options is included below.
- -t TYPE
Show only records of TYPE. This
argument can be repeated to indicate multiple types. Use the
"all" type to print all the known types.
- -m MATCH
- Show only records in which the first component matches the PERL regexpt MATCH.
- Show summary of options.
- Enable verbose mode. All DNS requests are printed in the standard error.
- Enable debug output. Presents internal information of the program
- Override warnings (force).
