GNS Installation on Fedora 19/18/17

What is GNS3 ?

GNS3 is an open source software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.

Here are the Steps to install GNS on Fedora 17/18/19:
First of all we need to install the telnet and pyqt4:
Telnet will give us the access console of our network devices:
#yum install telnet pyqt4
Now download the GNS3 form below link:

#tar -xjvf GNS3-0.8.4-src.tar.bz2

#cd GNS3-0.8.4-src/

#python2.7 setup.py build
