Now to install

The ns2 version taken here is 2.34 (ns-allinone-2.34) .Please modify to suit your version

Pre-Installation:

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)

You MUST put /home/~/Desktop/ns-allinone-2.31/otcl-1.13, /home/~/Desktop/ns-allinone-2.31/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=

> go to the terminal and try ns or nam

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

After these steps, you can now run the ns validation suite with
cd ns-2.31; ./validate
