  • Where do I go from here?
    If you mean a Cisco 2950, I guess you want to learn Networking. So a good place to start is to run GNS3 (https://gns3.com). You can download a VM image and run that, that's what I do. GNS3 is a great learning tool and you can use both real (your 2950) and virtual devices to make networks. Source: 7 months ago
  • Exploiting Wpa3
    GNS3 is the software your looking for it can be found here https://gns3.com let me know if you could use some resources on it. Source: 11 months ago
  • What skills are great to learn in a home lab for a beginner in IT ?
    GNS3 is a network device emulator, and more than a few devices requires lots of CPU and RAM resources. You need to pay for a licence for each device you want to emulate. Source: over 1 year ago

  • Cisco Routers for Learning?
    You might want to look into GNS3. It's a network emulator that supports Cisco ISO devices. It's been a while since I last used it, but at the time I found it to be indispensable as a learning tool. Source: over 1 year ago
