IEC'00 ns Lab 1 - OTcl and ns Basics

1. Installation
   Download the compressed tar file of ns-allinone-2.1b6 and place it in your home directory.

   Install ns using the following commands:

   	  tar zxvf ns-allinone-2.1b6.tar.gz
   	  cd ns-allinone-2.1b6
   	  ./install >& install.out
   

   When installation is over, view install.out with an editor and look for any possible errors. If you don't find any error, proceed; otherwise notify one of the instructors

   IMPORTANT SETUP:
   

   • Put ~/ns-allinone-2.1b6/bin in your default path.
   • By default you should be using tcsh. Add the following at the end of your .cshrc (create one if you do not have it). Also execute them in your command line so they will be effective for your current session:

     	setenv NS2HOME $HOME/ns-allinone-2.1b6
     	setenv TCL_LIBRARY $NS2HOME/tcl8.0.4/library
             setenv TK_LIBRARY $NS2HOME/tk8.0.4/library
             set path = ($NS2HOME/bin $path) 
     

   • Run and play with sample scripts
     Create a ns-test subdirectory at your home directory. Go to this sample directory and copy all the scripts into ns-test directory. Read and understand these scripts, then run them and see if your understanding is correct.

     	       % ns script.tcl
     

     If you encounter any run-time error, please notify the instructors.
