PacketDojo turns network troubleshooting into timed browser labs
A browser-based practice environment where aspiring network engineers repair router configurations, restore connectivity, and receive scored results.
Field notes
The exercises begin with an incident brief and topology, then move through route inspection, configuration changes, service testing, and simulator grading. Visible examples cover static routing, OSPF, and BGP, including a three-device topology and a failed traceroute. The page lists 240 challenges overall, with study paths for network-engineer foundations, routing interview practice, and troubleshooting that preserves access controls. Free access includes basic scores and two guided hints; reference configurations and worked solutions are attributed to Pro.
