Installing Network Simulator 2 (NS-2.35) on Fedora 16

NS is a event simulator, which can be used primarily for networking research. It provides support for simulation of TCP, routing, and multicast protocols over both wired and wireless networks.

NS can be installed on computers that run on Windows and Unix/Linux. Most use it on Linux system. This post will help you in installing Network Simulator 2 version NS2.35 in Fedora 16.

Install Fedora 16 using a DVD ISO (if you install it using a CD ISO, then you have to download few other packages and install them)

Installing the other Packages (if you install it using a CD ISO), in the following way:

Open terminal and become root by typing:
     su

First we need to install all the prerequisites of ns starting with our C++ compiler:
    yum install gcc-c++
    yum install tcl-devel
    yum install libX11-devel (that's one-one)
    yum install libXt-devel

Next step, Download the all-in-one package of any one of the following NS Versions

ns-allinone-2.35 Here

or

ns-allinone-2.34 Here

Other Versions of NS2 can be found here: http://sourceforge.net/projects/nsnam/files/allinone/

Next, go to the directory where you downloaded the NS tar file and copy it to where you want it to be installed.

Going back to the Terminal, navigate to the directory where you copied the ns-allinone-2.35.tar file.

Uncompress the ns2 file by executing the following commands:

tar zxvf ns-allinone-2.35.tar

or

gzip -d ns-allinone-2.31.tar.gz

Now execute following in the Terminal:

cd ns-allinone-2.35

./install

Once the installation succeeded, then the PATH information will be shown in the screen by the NS2

Copy the PATH and LD_LIBRARY_PATH Variable to ”.bash_profile” file.

Setting the PATH information in .bash_profile

Open .bash_profile file (vim .bash_profile).

There will be a PATH Variable already available in the .bash_profile file, just copy the PATH information from the NS2 installation and append it over the existing PATH variable (Don’t forgot to put a separator : between each path)

export PATH=$HOME/bin:<Put a colon [:] and Place your paths here>

export LD_LIBRARY_PATH=<place the LD_LIBRARY_PATHS> here.

Once done, save the file and close, execute the command

source .bash_profile

Once all these done, try “ns” command in Terminal (if you see a % indicates ns is installed successfully) or “nam” command (a animation window will be opened).
