plotnetcfg is a tool that scans networking configuration on the machine and plots a diagram of the configuration hierarchy. Design goals are: 1. Lighweight. It should have no run time dependencies. Just scp the binary to the target machine. 2. Works across net namespaces. 3. Allows multiple frontends (graphviz and json frontends are currently supported). Example usage: ssh target_machine plotnetcfg | dot -Tpdf > output.pdf Building: Jansson library is required, version 2.3 or newer: http://www.digip.org/jansson/ To statically link against Jansson, build the Jansson library and invoke in the plotnetcfg source directory: make jansson=/path/to/jansson To dynamically link against Jansson, ensure Jansson is properly installed in the system (e.g. using the devel package provided by your distribution) and invoke: make The following flags can be overridden during the build: - CC Choose a different compiler (such as clang or an arm cross compiler) - EXTRA_CFLAGS Additional compilation flags to pass to the compiler Bugs: Report bugs to email@example.com. Patches are welcome. Contains code from iproute2, originally licensed under GPLv2 or later, http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2
