Step 3: Unzip the ns-allinone-2.32.tar.gz

Use this command to unzip the files in your terminal 

$ tar -xzvf ns-allinone-2.32.tar.gz

$ cd ns-allinone-2.32 

Now run this command in terminal 

$./install 

Step 4:

After the successful installation, the path for bin, lib, Tcl, Tk and OTcl of the ns-allinone package has to be set by including the appropriate environment variables of bash shell in .bashrc file.

Step 5: NS2 Path Setting in Linux OS

after install ns-2 you should introduce ns-2 to your computer and edit the bash file in Terminal

$ gedit ~/.bashrc 

Add the following lines to the end of it. Remember replace “/your/path” by something like “/home/linuxhelpers”

# LD_LIBRARY_PATH OTCL_LIB=/your/path/ns-allinone-2.32/otcl-1.13 NS2_LIB=/your/path/ns-allinone-2.32/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=/your/path/ns-allinone-2.32/tcl8.4.15/library

USR_LIB=/usr/lib

export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH

XGRAPH=/your/path/ns-allinone-2.32/bin:/your/path/ns-allinone-2.32/tcl8.4.15/unix:/your/path/ns-allinone-2.32/tk8.4.14/unix

NS=/your/path/ns-allinone-2.32/ns-2.32/

NAM=/your/path/ns-allinone-2.32/nam-1.13/

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

Than it take effect immediately. $ source ~/.bashrc you should write command at the above, otherwise you can’t write ns2 successfully

Now, open new console and write ns, you will see % at the console. be carefully!!! You can see % after write ns at any path…by the way to exit from % you should write “exit” on your console.

Step 7: Validation

After these steps, you can now run the ns validation suite with

$ cd ns-2.32 $ ./validate 

After this process you can run some files from ns-allinone/ns-2.32/tcl/ex/…..tcl and see the results.

NAM

 when you run the tcl file if it generates a nam file you can trace it. HOW? go to path where is the tcl source code. than run your tcl code. and write “nam” on your console than small window will appear and click open file than choose your nam file and open it. after that you will see the simulation of your tcl code.

This ends the installation of ns-allinone package.
