ns-2 Installation script

ns-2 installation steps

You can access your work directory of ECE498nhv by typing 'ece498nv' (please note it's "nv" not "nhv") at any EWS UNIX prompt.
Create a new directory to install ns-related software. Make sure that you are in this directory, and download the ns-2 installation script there.
Set the script file permission to executable and run the script. You can use the following commands:
```
  chmod +x install-linux.sh
  ./install-solaris.sh
  
```
The installation script will create the ns-2 directory tree with everything linked to the original ns-2 files installed at a location mentioned in the script (Usually at /home1/e/ec/ece/ece498nv/ns/ns-allinone-2.28).
To setup your working environment, you need to add [ns-directory]/nam-1.11 and [ns-Directory]/ns-2.28 to the environment variable PATH. For example, if you are using csh, and ns-2 is installed under the directory /work1/ece498nv/[LoginName]/ns2-linux/, you can edit ~/.cshrc file and add the following command at the end of file.
NB: For some students, the ece498nv directrory is created in a different location. Please use "pwd" in the location where ns2-linux is to know the exact path. Usually you should ignore the leading "/nmnt/" in the reported location. For example, if the output of "pwd" is "/nmnt/work2/ece498nv/[LoginName]", the path to add would be "/work2/ece498nv/[LoginName]/ns2-linux/nam-1.11" "/work2/ece498nv/[LoginName]/ns2-linux/ns-2.28" etc. (notice that the leading "/nmnt" is removed).
```
  set path=($path /work1/ece498nv/[LoginName]/ns2-linux/nam-1.11 /work1/ece498nv/[LoginName]/ns2-linux/ns-2.28) 
  
```
For the change of environment settings to take effect, run the following command
```
  source ~/.cshrc 
  
```
You can now proceed with any changes to the source in your directory. To make changes to an existing file (say tcp-reno.cc) you will have to first delete the link from your ns-2 directory, copy the file from the original source into your ns-2 directory and then work on it.
After you are done with your changes, run "make" and a new ns will be created in your ns-2 directory. Use this to run your tcl scripts.
