Reverse proxy grapher

---------------------

This is a useful little tool that will generate a nice graphviz graph

illustrating your reverse proxy flow. It takes a manually curated YAML

file describing the topology of your network, proxy definitions, and

optionally a collection of nmap output files for additional port/service

information and output a graph in any format supported by graphviz.

Usage

~~~~~

When run with --help::

    usage: rev-proxy-grapher.py [-h] --topology TOPOLOGY [--resolve-dns]

                                [--nmap-xml NMAP_XML [NMAP_XML ...]]

                                [--limit-ext LIMIT_EXT [LIMIT_EXT ...]]

                                [--font FONT] [--fontsize FONTSIZE]

                                [--ranksep RANKSEP] [--out OUT] [--verbose]

    Draw a nice graph of your external to internal proxies

    optional arguments:

      -h, --help            show this help message and exit

      --topology TOPOLOGY   File describing the proxies and the topology of your

                            networks (default: topology.yaml)

      --resolve-dns         Attempt to resolve DNS for all IPs (default: False)

      --nmap-xml NMAP_XML [NMAP_XML ...]

                            Get additional node details from these nmap XML scan

                            files (default: ())

      --limit-ext LIMIT_EXT [LIMIT_EXT ...]

                            Only include these source IPs or networks (default:

                            ())

      --font FONT           Font to use in the graph (default: droid sans,dejavu

                            sans,helvetica)

      --fontsize FONTSIZE   Font size to use in the graph (default: 11)

      --ranksep RANKSEP     Node separation between columns (default: 1)

      --out OUT             Write graph into this file, guessing the output format

                            by extension (default: graph.png)

      --verbose             Be more verbose (default: False)

Requirements

~~~~~~~~~~~~

- python3-pydotplus

- python3-PyYAML

- python3-netaddr

Examples

~~~~~~~~

See output of --help, and examples in the examples directory. To

generate an example graph of your own, simply run::

    rev-proxy-grapher.py --topology examples/topology.yaml

This will generate graph.png if everything worked well.

If you want to see what is added by running nmap::

    rev-proxy-grapher.py \

        --topology examples/topology.yaml \

        --nmap-xml examples/nmap-external.xml \

        --out graph-with-nmap.svg

Limitations

~~~~~~~~~~~

Currently, this only supports one level of proxying. For example you cannot

define a haproxy->nginx->lb-cluster relationship, but this will hopefully be

coming in the future, as we have a need to get that properly represented

anyway.
