D Day-Installing ns2

The day finally came when i needed to install the ns2 simulator.

I was a bit afraid finally did it with out much hiccups.

u can download ns2 version 2.31 from the this link

remember the entire package would be available as allinone (ALL in One).

downloading that proved to be better for me than the individual packages.

the download text looks like this in that page.

Getting everything at once

Ns-allinone is a package which contains equired components and some optional components used in running ns. The package contains an "install" script to automatically configure, compile and install these components. After downloading, run the install script. If you haven't installed ns before and want to quickly try ns out, ns-allinone may be easier than getting all the pieces by hand.

Currently the package contains:

• Tcl release 8.4.14 (required component)
• Tk release 8.4.14 (required component)
• Otcl release 1.13 (required component)
• TclCL release 1.19 (required component)
• Ns release 2.31 (required component)
• Nam release 1.13 (optional component)
• Xgraph version 12 (optional component)
• CWeb version 3.4g (optional component)
• SGB version 1.0 (?) (optional component, builds sgblib for all UNIX type platforms)
• Gt-itm gt-itm and sgb2ns 1.1 (optional component)
• Zlib version 1.2.3 (optional, but required should Nam be used)

Currently, ns-allinone works on Unix systems and under Cygwin for Windows 9x/2000/XP. If you have problems with allinone, we encourage you to build it from its pieces.

Download source:

• current release 2.31 (released Mar 10, 2007)

Important:Please check the bug fixes after you finish installation! .
