but it is not a performance testing or a device/network stress tool. Bind it to whatever interface gets to the internet. There are numerous different bottlenecks in the way GNS3 operates and emulates the hardware, so the real throughput of a GNS3 topology is rather poor. Chose External so you can access it from other computers on your network and the internet. Click VMware VMware VMs and click New to open the Template Creation Wizard. However, creating a DDoS by sending extreme amounts of requests to an attached host - that might or might not work, because there are no physical interfaces between router instances in GNS3, and so there are no realistic bandwidth limitations. In the GNS3 program, there are network devices such as Switch, Router, and Hub in the Devices panel. Create a template for a VMware virtual machine Create a template for VMware virtual machine on GNS3. Whatever the reason, running GNS3 in a virtual machine, typically Linux based, is a popular way of running GNS3. If you mean DoS by, say, injecting false routing information then by all means, this is possible. This partly arose because early versions of GNS3 and even Dynamips were less stable on Windows platforms, or perhaps it was more a case of having a more detrimental effect on the underlying platform when the program crashed. DoS/DDoS attacks would depend on their nature. Basically, NAT appliance will provide you an IP address from which you can access the whole Internet. SQL injection, for example, is irrelevant to routers, as IOS-based routers do not expose any kind of SQL interface - neither a socket nor an API I know of. In order to connect your GNS3 appliances with Intenet, you have to choose NAT appliance from End Point devices and connect it to the Layer 3 device (i.e. I guess we need to narrow down what exact types of attacks you have in mind. The GNS3 Setup wizard starts automatically. Connect to the template VM by using remote desktop. Now that you installed GNS3, and added the GNS3 VM, configure GNS 3 to use the Hyper-V virtual machine. However, I am not sure about the attacks. After the script completes, confirm that the GNS3 VM virtual machine is available in Hyper-V Manager. To have more opportunity on GNS3, we can use virtual machines with this program as GNS3 VM. We can use this program to practice on various network devices by loading their images to GNS3. This means that that you will not be able to copy or move your VM as part of your GNS3 project. GNS3 is one of the most used network simulators in networking world. Any configuration settings of the virtual machines is controlled by the virtualization software and not GNS3. GNS3 is perfect to verify and learn about the functionality of different mechanisms in IOS-based routers. Be aware that GNS3 only integrates with VMware and VirtualBox and does not have control of the configuration of your virtual machines (VMs).
