dns_tree — command-line frontend to dig
Contents
Description
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.
