NAME¶

dns_tree — command-line frontend to dig

SYNOPSIS¶

dns_tree [-f] [-v] [-d] [-t TYPE] [-m MATCH] DNS_domain

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.

OPTIONS¶

A summary of options is included below.

-t TYPE

-v

Enable verbose mode. All DNS requests are printed in the standard error.
