Network Documentation Application Recommendations

[JoeSox <joesox () gmail com>]

Hello,

I first learned of NETDOT by Oregon State from this list but I have lost
the prebuilt VM image I had on file and looks like the source code out on
github doesn't compile anymore.

So I liked how NETDOT was
1) Free
2) Created Topology image on the fly
3) Connected to network devices via SNMP to get version and interface
details.

Any NETDOT replacement recommendations?
I have an https://www.networksecuritytoolkit.org box but not sure if any of
the builtin apps can do it yet, I don't remember seeing one in the build
but I may be missing it.
