Installing NS2 in simple 5 steps

Posted on August 23 2009 by Venkatanathan

Step 1: Download the source for NS2 all in one (I used this version ns-allinone-

2.34.tar.gz ) from the link http://sourceforge.net/projects/nsnam/files/

Step 2: Extract the tar.gz file downloaded into your home folder by right-

clicking the tag.gz file

Step 3: Open terminal (Applications–>Accessories–>Terminal) and change the

directory (using cd command) to the extracted folder and execute the following:

sudo apt-get install build-essential autoconf automake libxmu-dev

This will install the dependencies required to compile NS2 from the source.

The following command is used to compile the source.

./install

It will take long time to compile all the required packages for ns to work…

Step 4: Setting Environmental Variables

Type in terminal:

gedit ~/.bashrc

and append the following text to the opened file (Please note that the pathcontains the path in my system, replace “venkat” in path with your username)

# LD_LIBRARY_PATHOTCL_LIB=/home/venkat/ns-allinone-2.34/otcl-1.13NS2_LIB=/home/venkat/ns-allinone-2.34/libX11_LIB=/usr/X11R6/lib

# TCL_LIBRARYTCL_LIB=/home/venkat/ns-allinone-2.34/tcl8.4.18/libraryUSR_LIB=/usr/libexport TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATHXGRAPH=/home/venkat/ns-allinone-2.34/bin:/home/venkat/ns-allinone-2.34/tcl8.4.18/unix:/home/venkat/ns-allinone-2.34/tk8.4.18/unixNS=/home/venkat/ns-allinone-2.34/ns-2.34/NAM=/home/venkat/ns-allinone-2.34/nam-1.14/PATH=$PATH:$XGRAPH:$NS:$NAM

Step 5: Now, after editing the file, save and close it. Then in terminal type:

source ~/.bashrc

Try “ns” command, it shud go to the “%” prompt then it just means the

installation was successful! Enjoy

Note: These steps have been tested and worked like breeze in Ubuntu and is

expected work in all the debian based linux.

architecture you are concentrating on, like x86, Power PC or something.

Coz , I’m currently working on integrating ubuntu on ARM based

processors, specifically Cortex 9 series.

Doing lot of research on that and came to a conclusion that not a lot of

resource available on porting a full fledged OS with all necessary

applications on ARM. Experiencing lot of bottle necks and stuff.

Hope to have your help in few things.

Good luck

Oh, thats COOL I don’t know much about Cortex 9 series of processors,

but this, https://wiki.ubuntu.com/ARM might give you some directions. It

gives info ubuntu support for various ARM based processor. (it is possible

you might have come across it already, but just in case)

Hello

I did all the above and it worked great but when I write ( ns ) in step 5 it

says command not found.

Can you please help !

I am using ns-2.34 on ubuntu 9.10

Venkatanathan says:

October 30, 2009 at 4:52 pm

Check if you replaced the path in .bashrc file with the exact path to the ns2

source, (for me it was: /home/venkat/ns-allinone-2.34/ )

Your ubuntu version shouldn’t be a problem…

Did you complete step 3, sudo apt-get install build-essential autoconf

automake libxmu-dev ?

Make sure you are connected to the Internet when executing the above

command in terminal.

there is a line missing in the file config.in in the otcl folder provided with

allinone.

It can be found on ns-2 troubleshooting page on wiki. just google it.

Go to your otcl-1.13 folder, open the Makefile.in and make the following

changes in the 7th line:

From :

CC= @CC@

to :

CC= gcc-4.3

hi guys, i’m a newbie in linux and ns2… now, i am trying to install ns2 in

i’m following your instructions, but when i type ./install

Tcl is not part of the ns project. Please see http://www.Scriptics.com

to see if they have a fix for your platform.”

can you help me guys?? i really appreciates your help…

Venkatanathan says:


Hi Niket,

The steps should remain same, except you require to download the

appropriate Ns2 all-in-one version and while setting the environment

variables (that is the content to be put in .bashrc file) you should use the

correct paths. Thats all! (I haven’t tried with ns2.27 on 9.10 , but it should

work)

Hi Lordwin,

There is an various tutorials to learn NS2 online, here is one that might

help you: http://nile.wpi.edu/NS/

Hi, dwi prayoga

While extracting the source, you might have extracted in root user mode.

You should change the permission of the folder. “cd” to directory where you

have ns-allinone-2.34 directory and execute this command “sudo chmod -R

777 ns-allinone-2.34″. Now you shouldn’t havethat problem.

i have 2 do my final year project in NS2.. i ve successfully installed it acc 2

ur 5 steps.. can u pls temme how 2 proceed!! pls..

30.

Venkatanathan says:


You have to write the simulation script (TCL script) and save the file.

You can then execute the script using the command: “ns ”

There are many tutorials on how to write the scripts, one of them is : NS by

example (http://nile.wpi.edu/NS/)

Hope that was helpful!

varsha says:

February 15, 2010 at 12:45 pm

way 2 integrate my C++ code with NS2 to simulate the output..??? cos i
