Dear Mohit,

I could install the NS-2.35 on Ubuntu 12.04 successfully. But in terminal when I type ns, it does not show %; instead it gives error message as below -
“The program ‘ns’ is currently not installed. You can install it by typing:
sudo apt-get install ns2″
Then I have updated /.bashrc by adding below 3 lines at the end of file /home/.bashrc
export PATH=$PATH:/home/sangram/ns/ns-allinone-2.35/tcl8.5.10/unix:/home/sangram/ns/ns-allinone-2.35/tk8.5.10/unix
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/sangram/ns/ns-allinone-2.35/otcl-1.14:/home/sangram/ns/ns-allinone-2.35/lib
export TCL_LIBRARY_PATH=$TCL_LIBRARY_PATH:/home/sangram/ns/ns-allinone-2.35/tcl8.5.10/library

Still it gives same problem,
Is there any other incompatibility issue or configuration related issues?
Can you please help me in this regard?

Thank you.

Hi Mohit,
I could resolve the problem by updating ~/.bashrc file itself. I have set environment variables as below as the last of file
