To check whether ns3 installed successfully, use the following commands. $] cd ns-3.32/ $] ./waf --run hello-simulator You should get the output as Hello Simulator
$] ./waf --run first This is the example from the ns-3.32/examples/tutorial/first.cc file which will run directly using the above command But python files have to be moved to scratch folder.
