Simple network discovery

JaredBusch

I am going to a new client later today and one of the things I want to do initially is a simple network discovery.

Setting up something like PRTG or Spiceworks is out of the question. The first is too complicated to setup easily and quickly. The latter is a joke, not to mention I do not even have a Windows device to run it on.

I have heard about LibreNMS but never used it.

Any other light and fast suggestions?

Just run an nmap on the network?

Depending on how the initial analysis goes will depend if something better gets setup.

I've used Advanced IP Scanner to quickly figure out if there are devices configured statically on certain addresses, etc.

I used Angry IP too, but it requires Java.

I've used NMAP and generic open source device scanning solutions.

Right, but will this run in 'nix?

Oh, I missed that requirement. Skipped right over the "not to mention I do not even have a Windows device to run it on." part..

Have you tried Open-Audit?

For a Quick-N-Dirty, NMAP is my go to. For something more detailed, I go with OpenVAS.

We have Nessus but it's expensive. I usually just use nmap.

I haven't done it myself, but you should be able to script nmap to populate a list of hosts in csv format and import that into excel for review.

Would this work? It's an iOS app.

I prefer nmap/zenmap, but also use Fing as well.

Hard to beat nmap. If you had Windows or macOS I would recommend SoftPerfect, but not applicable here.

This is what I was going to suggest too. Zenmap (the GUI) has a bunch of helpful views, such as topology and host details.

Nmap with ZanMap Gui is great.
