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.
