compile and install iouyap, it is needed to interface the IOU executable with GNS3.compile and install VPCS, a sort of pc simulator that implements basic network testing functions like dhcp client, ping etc.

GNS3 is available on Windows, Mac OSX and on Linux, but it shines on Linux because, to use IOU, if you are not on Linux you need a Linux virtual machine running on VirtualBox.īut, because GNS3 glues together many moving parts, it can be troublesome to install everything and to have everything working seamlessly, for this reason i created a Docker image with everything installed, functioning and ready to be used on Linux (or in a Linux virtual machine running in Windows or Mac OSX).ĭocker is another fantastic piece of software that, together with CoreOS and other cloud orchestration projects, like Google’s Kubernetes, is one of the building blocks for the incoming Cloud Revolution.ĭocker containers (or Docker images) have similarities with virtual machines, but they run on same Linux kernel as the host, in a “ chrooted” environment using Cgroups and namespace isolation to provide resource limitation (on cpu and or RAM usage) and isolation from the other host processes that are invisible inside the Docker container. It also allows to connect the virtual network to the physical network, it is possible to access Internet in the emulated world and vice-versa. GNS3 is a fantastic piece of software, it glues together different open source software and allows to emulate a network that includes Cisco routers (using real Cisco firmware), Cisco switches (using IOU, Cisco IOS on Unix), Cisco ASA and any other devices that can run on Qemu or Virtual Box emulator.
