Simulate your network

Simulate your network

GNS3 - simulate your network - free Cisco IOS downloadWhether you are trying to learn or improve your networking skills, trying to troubleshoot a complex issue, or wanting to simulate your network to test new functionality, there is no better tool than GNS3. Yesterday, it was announced that the latest version, v1.0, was now officially available for download.

I’ve just downloaded this version of  GNS3 and can’t wait to get home an try it out. Unfortunately, the installation (on Linux at least) is not a simple matter of `point and click’, but I don’t think that’s going to scare too many Linux heads away.

Simulate your network

For me, the best thing about GNS3 is the ability to quickly and easily simulate your network, someone else’s network, or just try something new out that you’ve wanted. And the best thing about GNS3 is that it’s all virtual routers and switches, and patching is a simple matter of click-and-drag between the router icons on the screen – no crawling around in patch bays! #FTW

One feature that I’m really looking forward to playing with is the integration with VirtualBox (I’ll discuss VirtualBox in a later post). Having the ability to easily drop a virtual server/desktop into a simulated network makes it simple to generate real traffic, analyse it with WireShark, and get down in the weeds of the network without actually having to rack mount a chassis, cable up a server, or, realistically, even have to leave my desk.

GNS3 is available for Windows, Linux and Mac platforms. Come say “Hi!” in the GNS3 Forums when you signup!
