Configure gns3 vm12/19/2023 ![]() ![]() You will still need to provide your own IOU license file, and images, regardless of the import method used. Install an appliance from the GNS3 Marketplace.gns3a appliance templates, and using the Import Appliance wizard to import appliances, are covered in these articles: There are also IOU appliance templates available in the Appliances section of the GNS3 Marketplace to atuomate this process. (both types appear in the All Devices list) Create a virtual hard disk - I used 20GB. I use 1024MB RAM, and allow Dynamic Memory to add more if needed. Your IOU device will be selectable in the Switches or Routers device lists, depending on whether an L2 or 元 IOU image was used. Bind it to whatever interface gets to the internet. Your device is now listed among the IOU device templates: In the below example, an L2 IOU image was used, the type: was left set to “L2 image”, and it was given the name “L2”:Ĭlick Finish to complete the import process: Browse your filesystem to select the IOU image you want to import. ![]() (L2 image and 元 image are selectable in the dropdown menu) If a remote server has been set up, then that optional will become available) (Linux users can run IOU images via the local server. In the GNS3 Preferences menu, select IOU Devices, then click New:Īs this article uses the GNS3 VM in Windows 10, that’s the only available option in the Server type window, so click Next> to proceed: In the GNS3 GUI, click Edit -> Preferences -> IOS on UNIX:Ĭlick Browse to select your IOU license file, then click OK to proceed: Add the images: ![]() Only Cisco can provide you an IOU license, so don’t bother asking for it (or the images) on the GNS3 user forum!

You must provide your licence. There are plenty of other uses for NMAP, but this was just a simple test, to prove that it was functional: NMAP checks the target device, to see which SSH key exchange algorithms it supports. Prior to the following screenshot, the nmap container was assigned a static IP address, and connected to a router that had been preconfigured to allow SSH access to it.Ī quick test was run using the nmap -script ssh2-enum-algos target_ip command. Since it already exists in the GNS3 VM, there’s no need for the “docker pull” step that would occur, if we were going to use a container from Docker Hub. ![]() This “nmap” container will be listed in the End Devices toolbar. Back at the main Preferences screen, click OK to exit it. We won’t be specifying any environmental variables this time, as the defaults are fine for this example, so click Finish to complete this configuration process.

Give the container a name, and click Next>: Click Edit->Preferences->Docker Containers->New, like before, but instead of specifying a “New Image”, you’ll select “Existing image”, and then pick the one you just created from the dropdown list, and click Next> to continue: (the build time will vary, based on what you’re adding to the container, plus your PC) If the build was successful, you should see a message indicating that at the end of the output. Docker will cache each step of the build process. ![]()
