Installing Network Simulator(ns2.34) in Ubuntu10.10

Home / ns2 / Installing Network Simulator(ns2.34) in Ubuntu10.10

PROCEDURE 1:
This procedure works in all latest versions of Ubuntu.
Install ns,nam and xgraph by just a single command in the Terminal:

$ sudo apt-get install ns2 nam xgraph

You will be prompted for the user password. Enter it and watch Ubuntu do the things for You!

 

PROCEDURE 2:
These are the steps to install ns2.34, the traditional way.

Step1: Download ns-allinone-2.34 package from here: http://sourceforge.net/projects/nsnam/files/
I will be using ns version 2.34.

Step2: Place the ns-allinone-2.34.tar.gz file in your home folder(/home/micman in my case). Right click on the package and extract the contents in the same home folder.

Step3: Next, open the Terminal(Applications–>Accessories–>Terminal in ubuntu)

Step4: Change to ns-allinone-2.34 directory

$ cd /home/micman/ns-allinone-2.34

Step5: First, Install the dependencies

$ sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3

Note that we are downgrading the gcc version, as ns2.34 works well with gcc4.3

Edit Makefile.in found at this location ns-allinone-2.34/otcl-1.13/Makefile.in as follows:

Find the line that says:
CC= @CC@
and change it to:
CC= gcc-4.3

Step6: Begin ns2.34 installation

$ sudo su

# ./install

Step7: Once the installation is successful i.e. without any errors, we need to add the path information to the file ~/.bashrc

$ gedit ~/.bashrc

Step8: Append the following lines to the file ~/.bashrc

# LD_LIBRARY_PATH
OTCL_LIB=/home/micman/ns-allinone-2.34/otcl-1.13
NS2_LIB=/home/micman/ns-allinone-2.34/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=/home/micman/ns-allinone-2.34/tcl8.4.18/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH

XGRAPH=/home/micman/ns-allinone-2.34/bin:/home/micman/ns-allinone-2.34/tcl8.4.18/unix:/home/micman/ns-allinone-2.34/tk8.4.18/unix

# Note: the above two lines starting from XGRAPH should come in the same line

NS=/home/micman/ns-allinone-2.34/ns-2.34/
NAM=/home/micman/ns-allinone-2.34/nam-1.14/
PATH=$PATH:$XGRAPH:$NS:$NAM

Here replace /home/micman with the path to your home folder.

Step9: For the changes to take effect immediately, do the following:

$ source ~/.bashrc
Thats all!

type ns to see % and type nam to show the nam startup window. This shows your installation has been successful.
