Generating a network topology graph with Zenmap
Zenmap's Topology tab allows users to obtain a graphical representation of the network. Network diagrams are used for several tasks in IT, and we can save ourselves from having to draw the topology with third-party tools by exporting the topology graph of networks with Nmap. This tabincludes several visualization options to tweak the view of the graph.
This recipe will show you how to generate an image of your network topology with Zenmap.
How to do it...
Scan the network that you wish to map adding the --traceroute option in Zenmap:
# nmap -sV --traceroute scanme.nmap.org
Go to the tab named Topology. You should see the topology graph now, as shown in the following screenshot:

In this view, you may rearrange the location of the nodes and apply a few different visualization styles. When you are happy with the layout, click on Save Graphic...
