VLAN implementation using NS2

Tracegraph installation in Fedora 21

To install tracegraph (software that handles the tracing automatically by specifying the trace file generated from ns2)

OS Used: Fedora 21 (64 bit)
Tracegraph version: 2.02

Download the tracegraph software from this link

Since tracegraph is a 32 bit software, you need to install all the 32bit libraries. The following packages that ends with .i686 are related to 32bit libraries

Steps to install
$] su
and press the root password
$] yum update
$] yum install ld-linux.so.2 libXext.i686 libXt.i686 libXp-devel.i686 
Still if trace graph is not working, install these software too (this will also help in installing ns-2.35)
$] yum install tcl tk gcc-c++ libX11-devel libXt-devel libXmu-devel

To install Tracegraph
untar the software after copying it to your home folder (/home/pradeepkumar) in my case.
$] tar zxvf tracegraph202.tar.gz
$] cd tracegraph202
After the above step, you need to set the LD_LIBRARY_PATH
Open the file /home/pradeepkumar/.bash_profile and give this line in the file
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/pradeepkumar/tracegraph202/bin/glnx86
and save the file and logout and login back.
$] ./trgraph 
This should pop out three windows, then tracegraph is installed successfully.

Since tracegraph is a very old software, there could be some bugs in the recent Operating Systems. So whenever you open the tracefile, use the following command to open the files (Rather than using the File menu within tracegraph)

$] ./trgraph /path/to/file.tr
