6. Execute “install” in Terminal.

7. In the very directory, use the command:
echo “PATH=/Users/username/ns2/ns-allinone-2.31/bin:$PATH” > .bashrc
   Remember to modify the red parts to the directory that you keep the NS2 folder.


8. Go to your home directory, add the following line to “.profile” :


export PATH=$PATH:/Users/wangxiaofei/work/ns/229/bin:/Users/wangxiaofei/work/ns229/tcl8.4.11/unix:/Users/wangxiaofei/work/ns/229/tk8.4.11/unix
 
export LD_LIBRARY_PATH=/Users/wangxiaofei/work/ns/229/otcl-1.11:/Users/wangxiaofei/work/ns/229/lib
 
export TCL_LIBRARY=/Users/wangxiaofei/work/ns/229/tcl8.4.11/library
Again, remember to modify the red parts.



9. Use the command: source .profile


10. Use the command “ns” and “nam” to see if the installation success or not.


11. If command “nam” is not working, try to find the folder nam-x.xx in the ns-allinone-x.xx. Make again. And then add the path to .profile as mentioned in step 8.


12. If you have any problem following this tutorial, feel free to ask questions.
