Install ns-2 Simulator in fedora 13

What is ns-2 Simulator??

Ns is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.

Download:

First you need to download ns-2 Simulator
link: NS-2 Simulator Download

Pre-Installation:

Before your ns-2 installation few packages must be already installed. Required packages (for fedora only) are:
1. yum install gcc.
2. yum install tcl-devel.
3. yum install libX11-devel.
4. yum install libXt-devel.

Note:
This is an important for f14 users. Fedora 14 users have to do some changes in the code of ns-2.34 (inside some .cc files) before install.
For eg:. lets take an example code "Test::Test(para1, para2).value();" it has to be changed into "Test(para1,para2).value();"

Installation:

1. Unarchive the downloaded file "ns-allinone-2.34.tar.gz" into /opt
$ tar -xvf ns-allinone-2.34.tar.gz
2. open terminal type
$ cd /opt/ns-allinone-2.34/
3. Start the installation process
$ ./install
4. At the end of installation you can see few lines like:

Libraries have been installed in:
/opt/ns-allinone-2.34/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

..................(few lines)
Please put /opt/ns-allinone-2.34/bin:/opt/ns-allinone-2.34/tcl8.4.18/unix:/opt/ns-allinone-2.34/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:
1. You MUST put /opt/ns-allinone-2.34/otcl-1.13, /opt/ns-allinone-2.34/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=

2. You MUST put /opt/ns-allinone-2.34/tcl8.4.18/library into your TCL_LIBRARY environmental variable. Otherwise ns/nam will complain during startup.

Setting the environment variables:

Add all these lines into your ~/.bashrc file:
export PATH=$PATH:"/opt/ns-allinone-2.34/bin:/opt/ns-allinone-2.34/tcl8.4.18/unix:/opt/ns-allinone-2.34/tk8.4.18/unix"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/opt/ns-allinone-2.34/otcl-1.13:/opt/ns-allinone-2.34/lib"
export TCL_LIBRARY=$TCL_LIBRARY:"/opt/ns-allinone-2.34/tcl8.4.18/library"

Validate successful installation:

After these steps, you can run the ns validation suite with
$cd ns-2.34; ./validate

1. Now its time to check if your installation is really successful. You can do so by:
$ cd /opt/ns-allinone-2.34/ns-2.34
$ ./validate (this will take some time)
