Ubuntu Manpage: mapper - Create graphical maps of DNS zone data

NAME

           mapper - Create graphical maps of DNS zone data

SYNOPSIS

           mapper [options] zonefile1 domainname1 ... zonefileN domainnameN

DESCRIPTION

       This application creates a graphical map of one or more zone files.  The output gives a graphical
       representation of a DNS zone or zones.  The output is written in the PNG format.  The result can be
       useful for getting a more intuitive view of a zone or set of zones.  It is extremely useful for
       visualizing DNSSEC deployment within a given zone as well as to help discover problem spots.

OPTIONS

-h Prints a help summary.

-o OUTFILE.png
Saves the results to a given filename. If this option is not given, the map will be saved to
map.png.

-r Lists resource records assigned to each node within the map.

-t TYPE,TYPE...
Adds the data portion of a resource record to the displayed node information. Data types passed will
be automatically converted to upper-case for ease of use.

Example usage: -t A will add IPv4 addresses to all displayed nodes that have A records.

-L Adds a legend to the map.

-l (neato|dot|twopi|circo|fdp)
Selects a layout format. The default is neato, which is circular in pattern. See the documentation
on the GraphViz package and the GraphViz Perl module for further details.

--node-size=(none|small)
If the map size is too large, it is possible to either greatly reduce the node size (and the text)
using --node-size=small or eliminate the circles entirely, leaving only the arrows using
--node-size=none. This can make for better visual diagrams of very complex node sets, although all
labeling is lost.

-a Allows overlapping of nodes. This makes much tighter maps with the downside being that they are
somewhat cluttered. Maps of extremely large zones will be difficult to decipher if this option is
not used.

-e WEIGHT
Assigns an edge weight to edges. In theory, >1 means shorter and <1 means longer, although, it may
not have any effect as implemented. This should work better in the future.

-f INTEGER
Uses the INTEGER value for the font size to print node names with. The default value is 10.

-w WARNTIME
Specifies how far in advance expiration warnings are enabled for signed resource records. The
default is 7 days. The warning time is measured in seconds.

-i REGEX
Ignores record types matching a REGEX regular expression.

-s TYPE,TYPE...
Specifies a list of record types that will not be analyzed or displayed in the map. By default, this
is set to NSEC and CNAME in order to reduce clutter. Setting it to "" will display these results
again.

-T TYPE,TYPE...
Restrict record types that will be processed to those of type TYPE. This is the converse of the -s
option. It is not meaningful to use both -s and -t in the same invocation. They will both work at
once, however, so if -T specifies a type which -s excludes, it will not be shown.

-g Attempts to cluster nodes around the domain name. For "dot" layouts, this actually means drawing a
box around the cluster. For the other types, it makes very little difference, if any.

-q Prevents output of warnings or errors about records that have DNSSEC signatures that are near or
beyond their signature lifetimes.

--dump-styles
Dumps the current style settings for both nodes and edges.

--node-style=FORMATS
--edge-style=FORMATS
Allows specific style settings to be used when drawing nodes and edges. Major format specifications
are delimited by '/'s and pairs within that are delimited by ':'s. The first token in a ':' list is
expected to be the record name.

For example, to make all A address records appear as a red box and all MX records to appear as a
triangle use this specification:

--node-style=A:shape=box:fillcolor=red/MX:shape=triangle

Run mapper with --dump-styles to show its default settings and/or how you've modified it the options
have been used.

EXAMPLE INVOCATIONS

       mapper -s cname,nsec -i dhcp -L zonefile zone.com
           Writes  to  the  default file (map.png) of a zone.com zone stored in zonefile.  It excludes any hosts
           with a name containing dhcp and ignores any record of type CNAME or NSEC.  A legend  is  included  in
           the output.

       mapper -s txt,hinfo,cname,nsec,a,aaaa,mx,rrsig -L zonefile zone.com zonefile2 sub.zone.com ...
           Removes a lot of records from the display in order to primarily display a map of a zone hierarchy.

       mapper -l dot -s txt,hinfo,cname,nsec,a,aaaa,mx,rrsig -L zonefile zone.com zonefile2 sub.zone.com ...
           As  the  previous example, but this command draws a more vertical tree-style graph of the zone.  This
           works well for fairly deep but narrow hierarchies.  Tree-style diagrams rarely look as nice for  full
           zones.
