Networking with Linux

In this we are going to learn network topology logical working using NS-3 and Wireshark simulator.

This simulator nothing but software model in analogus to hardware working of network.

For. Transmission of Packet over Network node shown in NS-3 GUI window.

To download NS-3 refer below website https://www.nsnam.org/

https://www.nsnam.org/

Step 1.

On Ubuntu Terminal type command

sudo apt update

Step 2. After fetching latest package install it command is

sudo apt install

Step 3. After installation upgrade Ubuntu command is

sudo apt upgrade

Step 4. To Install C++ complier in Ubuntu then follows following command

sudo apt-get install build-essential

Step 5: To install Python compiler use following command sudo apt-get install python python-dev

Step 6: To install Mercurial means animation and NS3 supported package use following commands

sudo apt-get install mercurial

Step 7: To unzip file install supported package command is

sudo apt-get install bzr

Step 8: to install TCPDUMP for pcap trace file reading support use following command

sudo apt-get install tcpdump

Step 9: to Generate XML supported file to be readble file external simulator API use the following command

sudo apt-get install libxml2 libxml2-dev

Step 10: Unzip the NS3 package we have command

tar xjf ns-allinone3.32.tar.bz2

Step 11: To compile all the package in ns-3.32 execute following command

./waf configure --enable-examples –enable-tests

Step 12: To run our simulator then every classess must be compile. Use the following command

./waf –-run hello-simulator

After executing above commands then output will “ Hello Simulator” then assume that all NS3 API are in executable code of Operating System.

$

$

$

$

$ cd

mkdir workspace cd workspace

wget https://www.nsnam.org/release/ns-allinone-3.32.tar.bz2

tar xjf ns-allinone-3.32.tar.bz2

Notice the use above of the wget utility, which is a command-line tool to fetch objects from the web; if you do not

have this installed, you can use a browser for this step.

Following these steps, if you change into the directory ns-allinone-3.32, you should see a number of files and

directories

$ cd ns-allinone-3.32

$ ls

bake constants.py

build.py netanim-3.108 ns-3.32

pybindgen-0.21.0 README

util.py

You are now ready to build the base ns-3 distribution and may skip ahead to the section on building ns-3.

Now go ahead and switch back to the debug build that includes the examples and tests.

$ ./waf clean

to compile all API classes use following commands

$ ./waf configure --build-profile=debug --enable-examples –enable-tests

if you don’t see the “Hello Simulator” output, type the following:

$ ./waf configure --build-profile=debug --enable-examples –enable-tests

and ten type command

./waf configure –enables-examples

and

./waf --run hello-simulator
