I think your installed ns2 is not in your bash_profile path. execute which ns in terminal. it displays which ns is currently working. If it is usr/bin its default ns .now give path to your ns using PATH command. hope it helps

Question
I run ns-2.35 on my Ubuntu 12.10
While I finished installing my ns2 and tried to run via "sudo ns xxx.tcl", it showed on the screen saying that there was no ns2 on my computer and I have to use "apt-get install ns2". I used it, and then it was installed successfully.
Now I modify some .cc files and recompile my ns2, and it is successful, too.
But the problem is that the results are not modified as I want. In fact, the result doesn't change. It seems my modification doesn't really change anything in my ns2. Why? There's no error in my installation or compilation? I am so confused. Is there anyone face the same problem? Thanks in advance!

hope it helps ..!! Enjoy
1) Download 'ns-allinone-2.35' from : http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download
2) Extract the downloaded zip file 'ns-allinone-2.35.tar.gz file' to desktop.
3) Now you need to download some essential packages for ns2,these packages can be downloaded by using the following command : applications>accessories>terminal or dashhome>trminal then type the below line on the terminal window
"sudo apt-get install build-essential autoconf automake libxmu-dev libtool gcc"
or type this command
"sudo apt-get install autoconf automake gcc g++ build-essential libxmu-dev libtool libxt-dev"
4) Now change your directory(here i have already extracted the downloaded files to desktop,so my location is desktop) type the following codes in the command window to install NS2.
cd Desktop
cd ns-allinone-2.35
./install
The installation procedure will take a few minutes..........
5) After compleating the installation type the following command in the command window
gedit ~/.bashrc
6) Now an editor window appears,please copy and paste the follwing codes in the end of the text file (note that '/home/abhiram/Desktop/ns-allinone-2.35/octl-1.14' in each line in the below code should be replaced with your location where the 'ns-allinone-2.35.tar.gz'file is extracted)
# LD_LIBRARY_PATH
OTCL_LIB=/home/abhiram/Desktop/ns-allinone-2.35/otcl-1.14
NS2_LIB=/home/abhiram/Desktop/ns-allinone-2.35/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:$USR_LOCAL_LIB
# TCL_LIBRARY
TCL_LIB=/home/abhiram/Desktop/ns-allinone-2.35/tcl8.5.10/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB
# PATH
XGRAPH=/home/abhiram/Desktop/ns-allinone-2.35/bin:/home/abhiram/Desktop/ns-allinone-2.35/tcl8.5.10/unix:/home/abhiram/Desktop/ns-allinone-2.35/tk8.5.10/unix
NS=/home/abhiram/Desktop/ns-allinone-2.35/ns-2.35/
NAM=/home/abhiram/Desktop/ns-allinone-2.35/nam-1.15/
PATH=$PATH:$XGRAPH:$NS:$NAM
7) Save and close the text editor and then type the following command on the terminal
source ~/.bashrc
8) Close the terminal window and start a new terminal window and now change the directory to ns-2.35 and validate ns-2.35 by exicuting the following command ( it takes 30 to 45 minutes)
cd ns-2.35
./validate
9) If the installation is successful, then you will be able to see % at the command prompt while typing the following command
ns
10) Now type
exit
