I am new to network simulation and I have recently installed ns2 by using ns-allinone-2.35. After installation I gave environment path settings and run a sample tcl file in terminal. The terminal shows the output and the folder contains the output file, but the network animator does not shows up.

And when I try nam in terminal it shows Segmentation fault (core dumped)

What should I do to ensure that the nam is working and show the outputs properly.

First of all let me say that you don't have to go through so much trouble... You just need to download a version of nam, and use it to show your output.
To do that i have uploaded the nam file for you and it will work fine, you just have to download it and open your output using this nam :

Filesize: 2.620 MB

Example :

/ns-allinone-2.35/ns-2.35# ./nam ./out.nam

OK, the usual : You installed the old faulty Ubuntu 'nam' package. Bug reported ~2 years ago.

See child killed: segmentation violation

»» environment path settings «« : Not required, if it's your computer. This will do :

$ cd ns-2.35/ && sudo make install

Reinstall or if NS is working then follow only install NAM section it will work, it works for me.

Uninstall the already existing nam using sudo apt-get remove nam

Now, head to https://drive.google.com/file/d/1dkNPNN23Vy6o_zT0uIRBgUAo1VCXcVOY/view and download the debian package nam_1.14_amd64.deb

Install it using Ubuntu Software Centre or dpkg command sudo dpkg --install nam_1.14_amd64.deb
