Network Simulator 2 - presentation Slides

I have gone across more than 80 institutions in the country to give hands on session, workshop, seminars related to network simulator 2. Mostly I will try different simulations, different models for simulation, etc.

But basically, every researcher/students needs some basics to get to know about ns2.

These slides make you understand the basics of ns2. Still in the country, there are so many universities uses ns2 as their simulated platform for the networking course, wireless networks course, etc. reading these slides make you know the basics of ns2.

These slides can be downloaded from my slideshare profile.

Error: Meta size 4064 too large (max = 1000)

Error: Meta size 4064 too large (max = 1000)

When using Mannasim Simulator for ns2, you may encounter this error when you are trying to run a tcl file with LEACH protocol. Here is a small workaround for the solution.

To install mannasim, please go here.

To overcome the above error, open the file
and change the following line

struct hdr_rca {
       int msg_type_;
       char meta_[1000];


struct hdr_rca {
       int msg_type_;
       char meta_[5000];

Since I get 4064 as meta size, i changed it to 5000, if you get more than 4064, then accordingly you can increase the meta size and compile it. 
Here is the important step to compile
~ns-2.35 $] ./configure --with-tcl-ver=8.5
~ns-2.35 $] make

Sometimes simply typing make will compile, but the .object files would not be created. So use the above two steps.

Here is the screenshot.

Installing Kali Linux Tools in Ubuntu or Linux Mint

Kali linux is a debian based and its not easy to configure it on a typical PC. If the machine is UEFI based, then Kali is tough to customize.

So what is the alternative....? Here is the answer: Katoolin

Its the name of the package system for installing the entire kali linux tools (Penetration Testing) in Ubuntu or Debian based system.

Here I am trying to install inside my Linux Mint

OS Used: Linux Mint 18.2 Sonya
Prequisites: Python 2.7
Always perform these steps after the installation of ubuntu or Linux Mint

$] sudo apt update
$] sudo apt install build-essential autoconf automake libxmu-dev
$] sudo apt install git
$] git clone
$] sudo cp katoolin/ /usr/bin/katoolin
$] sudo katoolin

This will give various options as shown below
 In the above pic. Select 2 to View categories and you will get the screen as shown in the next image.
Select "0" to install all the applications.

This will install 1.3G to download and 3.5 GB space will be…

TCL installation error

In case, if ns2 have to be recompiled based on a new addition of protocol or agent, there should be an entry to the After the changes are made, the following things need to be done to compile the agents.

$] ./configure 
$] make 

but ./configure may throw an error as shown below like
"Configure: Error: Installation of Tcl Seems to be incomplete or not found"

To correct this problem, please try the following

$] ./configure --with-tcl-ver=8.5 

The above works only after the successful installation of ns2. If you are installing ns2 for the first time refer this blog post
