Hello, I am a final year Electrical and Electronics Engg student at BITS Pilani (top private university in India). I have been using Ubuntu from past 2.5 years.I am also a good linux user.
I had installed ns2, 6 months ago on my laptop. I can share a complete documentation on that.
Also, I have figured out a way to install tracegraph, won't be a problem.
Please give me this opportunity, and I ensure you that you won't have any errors in the installation.
I am a student, and I understand your issue with the installation.
