Network Simulator 2

I am installing NS2 v2.33(latest version) on fedora 9(i386). There are two ways to install it either piece wise or all in one. Here i am installing all in one because it is simple.

• Download all in one package from NS website.
• It is ".tar.gz" format so extract it on your fedora desktop.
• Open terminal
• Type "cd Desktop" and press enter(as your ns folder is on desktop)
• Now type "cd ns-allinone-2.33" and press enter
• Type "./install" and press enter. It will automatically install all the compoents in the folder and it will take some time.
• When done. Now type "gedit ~/.bashrc"
• Add the following lines of code at the end of the file (remember to replace"/home/hassan/desktop" with your installation path)

# LD_LIBRARY_PATH

OTCL_LIB=/home/hassan/Desktop/ns-allinone-2.33/otcl-1.13

NS2_LIB=/home/hassan/Desktop/ns-allinone-2.33/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/hassan/Desktop/ns-allinone-2.33/tcl8.4.18/library

USR_LIB=/usr/lib

export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH

XGRAPH=/home/hassan/Desktop/ns-allinone-2.33/bin:/home/hassan/Desktop/ns-allinone-2.33/tcl8.4.18/unix:/home/hassan/Desktop/ns-allinone-2.33/tk8.4.18/unix

NS=/home/hassan/Desktop/ns-allinone-2.33/ns-2.33/

NAM=/home/hassan/Desktop/ns-allinone-2.33/nam-1.13/

PATH=$PATH:$XGRAPH:$NS:$NAM

• Now type "source ~/.bashrc"
• Installation is completed. To check whether your installation is correct type "ns" a "%" will appear on the screen enter "exit". Type "nam" this will open network animator. I hope this tutorial will be helpful for you.
