or
gzip -d ns-allinone-2.31.tar.gz
tar xvf ns-allinone-2.31.tar

2) cd /opt/ns-allinone-2.31 (since /opt is the folder which is unused, so i have selected that folder to install, however you can install that in any folder)

3) ./install (execute the command)

4) If the installation fails in the middle, then try to install the linux packages that are

necessary to run NS2. (In any linux (ubuntu or fedora or redhat or suse), install the TCL/TK, Perl packages during the installation of linux...)

5) Once the installation succeeded, then the path information will be provided by the NS2

6) Set the path in the /root/.bash_profile

or
If you are a user home//.bash_profile (for example, if your the username is tsp, then execute this command vi /home/tsp/.bash_profile)
7) set the PATH and the LD_LIBRARY_PATH according to the point number 11.

8) logout and login.

9) go to the terminal and try ns or nam

10) for running the examples comes along with the distribution of NS2
cd /opt/ns-allinone-2.31/ns-2.31/tcl/ex
