dns_tree

dns_browse(1)						      General Commands Manual						     dns_browse(1)

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	 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.

       -h	 Show summary of options.

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

       -d	 Enable debug output. Presents internal information of the program

       -f	 Override warnings (force).

SEE ALSO

       dig (1), dns_browse (1), perlrequick (1).
