Hi Zeinab, Segmentation faults are usually due errors in the Code you've implemented in the C++ domain. They are mainly caused by wrong pointers, when you try to access some memory location which has been freed. That's just one scenario. There you have to debug the C++ code it on your own, step by step.
Sometimes they are also due to wrongly implemented connections (taking into perspective the agents attached to the nodes) in your tcl code. For example, if you attach an forwarding agent to a sink and expect it, without any modifications, to send packets downstream, you'll most probably get a segmentation fault.
