1.To download the new version follow this link http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download1.Copy the downloded ns 2.35 file in cygwin/home. (I have copy it in C:/cygwin/home through mouse)2. Open Cygwin by clicking the icon on the desktop3.Now write “pwd” without inverted commas it will show your present working directory. ( I have got like /home/lenovo).

04/11/20238

To enter into any directory simply write

$cd /home ;press enter home is the directory name

$ls ; it will show the list of containing files in yours directory

4.Now goto that directory in which you have copied the ns2.35. (I have done so cd ..,now I am in /home directory.).

5. Extract the package by writing this. tar -xvf ns-allinone-2.35-RC3.tar

(be careful write the same name of ns file what you have coppied) (I have write ns-allinone-2.35, bz I have coppied this name in cygwin)

04/11/20239

A. $cd ns-allinone-2.35 ;(press enter)B. $./installB. Wait for installation to complete.C. Now if you have at the end of the window

the same like below then it’s ok you have done it.

Now the most difficult thing is to set your bashrc file. Be careful I have wasted much of my time on this. But hope you will not.

Cd ~/nano ~/.bashrcNow simply copy the page # 13 text and past

it in the terminal. Only change the path (don’t confuse with this is so simple put your place where you have install the ns-allinone-2.35, I have install it in home/ns-allinone-2.35/ you have to write your own.)

Once you made it you can copy Or manually store the bashrc file in ‘etc’ folder in cygwin through mouse.

04/11/202312

Be careful to write otcl8.5.10,tk1.14,ns2.35, e.tc file names, because it changes with change of ns version.

Important to note:When you entering a directory by this

commandCd /home .when you enter in terminal

you can check it also in your computer by openning C, then cygwin, then home, then ns-allinone-2.35 through mouse.
