sudo apt-get install dynagen dynamips iptables-persistentĤ. You will need be root or a sudo privileged user.ģ. This is how i got my network in a box created: To get around this, I got went and got myself a dedicated server from UK Dedicated Servers and installed the packages that were being used behind the GNS3 GUI interface. The issue I found was when I wanted to have large scale topologies, my laptop wasn’t able to cope and the heat was amazing (not in the good way!). Originally, I was using GNS3 (an awesome tool for network engineers, whether a noob or a season vet) to emulate Cisco IOS routers. Having worked with a couple of pretty cool and smart engineers PacketJedi from and Darren from .uk, they suggested that I should look into creating a Virtual Cisco Lab with a server. If you’re like myself who doesn’t have the space, time, money or power in your own home, having a large scale network lab isn’t really possible.
