Generating a network topology graph with Zenmap
Zenmap's topology tab allows users to obtain a graphic representation of the network that was scanned. 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 from Nmap. This tab also includes several visualization options to tweak the view of the graph.
This recipe will show you how to generate an image of your network topology by using Zenmap.
How to do it...
Scan the network that you wish to map in Zenmap, using the following command:
# nmap -O -A 192.168.1.0/24
Go to the tab named Topology. You should see the topology graph now, as shown in the following screenshot:
Click on Save Graphic in the top-right corner.
Enter a filename, select a file type, and click on Save, as shown in the screenshot below:
How it works...
