Recently I wanted to have a graphical representation of my passively collected network traffic. I have previously used LANMAP as a tool to build network pictures, but that tool is pretty old, and I knew there was something better. LANMAP2 is built into BT, but there is some arguments as to if that is actually worse than LANMAP or not. Besides, that is a static tool, and I wanted something more dynamic.
I found SMART (Safe Mapping and Reporting Tool), and that is now my graphical network mapping tool of choice. SMART not only allows for both real-time and pcap file runs of traffic, but it also runs p0f on the traffic to ID nodes (it would be nice if it put icons of OSs, but it just puts the OS information as text). Here's what SMART looks like:
When you click on a node in the graph, it opens a view to show you what types of traffic that node is sending (note the p0f OS identification):
Installing SMART was a snap. You first download smart from sourceforgesourceforge.net/projects/safemap/. I used
smart-1.0.tar.gz
go to your directory, and unzip the smart package with 'tar -xzvf smart-1.0.tar.gz'
The INSTALL file will give you install instructions. For BT5R3, before you proceed you have to grab graphviz from www.graphviz.org
www.graphviz.org->Download->Agree->Source">www.graphviz.org->Download->Agree->Source
Code->graphviz-2.28.0.tar.gz
unzip it with 'tar -zxvf graph...'
cd graphviz-2.28.0
./configure
make
make install
Check that graphviz installed correctly by typing 'dot -v' at a terminal (in the smart directory). You should get a version. Mine said 'dot - graphviz version 2.28.0 (20121201.1358)'
To install SMART, just run 'perl Build.PL'
That's it! SMART is now installed. To test it, first start SMART looking at a live capture.
./smart.pl -N "My Network" -x -p -d -i eth0 -t 10 -L "^192\.168\." (see smart.pl -h for help)
Next, launch a browser, and open the index.html page in the smart directory.
You should now see your network map graphically growing! SMART is awsome!
