Set environment variables

$ gedit ~/.bashrc

Add the following lines to the end of it. Remember replace "/your/path" by something like "/home/purple"

# LD_LIBRARY_PATH
OTCL_LIB=/your/path/ns-allinone-2.31/otcl-1.13
NS2_LIB=/your/path/ns-allinone-2.31/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY
TCL_LIB=/your/path/ns-allinone-2.31/tcl8.4.14/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH
XGRAPH=/your/path/ns-allinone-2.31/bin:/your/path/ns-allinone-2.31/tcl8.4.14/unix:/your/path/ns-allinone-2.31/tk8.4.14/unix
NS=/your/path/ns-allinone-2.31/ns-2.31/
NAM=/your/path/ns-allinone-2.31/nam-1.13/
PATH=$PATH:$XGRAPH:$NS:$NAM

Let it take effect immediately:

$ source ~/.bashrc

Note: the step described above is important;otherwise, you cannot run ns successfully.

(or you can restart your X windows,i.e. logout and then login, or reboot your system, to make it work.)

Now,the installation has been completed.If you try:

$ ns

Then a "%" will appear on the screen.type "exit" to quit the mode and back to "$"

Validation

After these steps, you can now run the ns validation suite with

$ cd ns-2.31
$ ./validate

Possible error messages

If you typed "ns" and got the following:

The program 'ns' is currently not installed. You can install it by typing:
sudo apt-get install host  '''(don't do this)'''
Make sure you have the 'universe' component enabled
bash: ns: command not found

It probably means the environment variables haven't been set correctly. Make sure the ~/.bashrc file has been edited correctly and that it has either been source'd as described above or that the system has been rebooted.
