GNS3 team is working smart and harder day by day to make Gns3 stable. Gns3 is a Graphical Network Simulator that allows emulation of complex networks.It is very crucial for people studying for certifications like CCNA up to CCIE level.With every new release there is something new added and improvements.


I have written articles previously on How to install Gns3 on Kali Linux and Debian. Today i will write an article on how to install Gns3 1.3.9 as of this writing on Kali Linux 2.0, Debian 8 and Latest ubuntu.
This article will work on other new release of Gns3 and i will post an update when new release come out. Gns3 on Linux come with 7 components that we'll build one by one.

Dynamips 0.2.14
gns3 gui 1.3.9
