Draw your Network's Topology using Zenmap

I have been using Nmap for a long time now. It is a really good command line network scanning tool. I use it for almost all my scanning needs. There is also a graphical frontend available, Zenmap. It has a simple interface with some pre defined commands and provision for entering commands manually. But the feature I like most is its ability to draw topologies. Run traceroute for different IPs and it will draw a Network Topology for you.

This is how it works. First of all download and install Zenmap from here. If you are using Ubuntu you can directly use this command

[shredder12]$ sudo apt-get install zenmap

If you are using fedora, try this

[shredder12]$ yum install zenmap

Once, you are done with the installation. Open Zenmap and you will see this window

Enter the IPs you want to scan in the Target field separated by white spaces and select “quick traceroute” from the Profile field. The command field will be automatically generated. Hit scan and the IPs will be scanned for you.

Once the scanning is complete click the topology tab and you will see a small topology created. Look at the following screenshot:

Whatever you scan next will be added to the topology. You can even select any node and change the topology keeping it as the center(just click on the node).
