Dear #network teachers, students and #hacker friends, I have a #browser based network simulator to enable learning #networking. Please have a look and tell me what do you think. Made for desktop or bigger screens. https://howcomputer.works/netsim/ Everything is in the browser, and there is documentation. The goal is to allow kids to start learning while their schools/systems are not big enough to be able to build lab networks. It has a small/minimal #curl implementation too. @bagder@mastodon.social

@kushal@toots.dgplug.org @bagder@mastodon.social Thanks for sharing this project! It looks really promising. I'm going to try using it to model the network for my #NixOS homelab project and see how well it fits that use case. I'll be sure to share my feedback once I've had a chance to test it. Really appreciate the work you've put into making networking more accessible for learning. https://github.com/badele/nix-homelab

@kushal@toots.dgplug.org @bagder@mastodon.social then they can graduate to https://gns3.com/ In 2008 I used the version available back then (dynamips underneath) with Cisco IOS images to create complex networks and learn MPLS-VPN and TE
