Two academy courses ready to install

“Network basics” and “Fault finding in networks” install straight from GitHub, in German and English, with lessons, quizzes and fault hunts.

Their full names are Network basics and Fault finding in networks. The first leads in 24 steps from the cable to the name: hosts and switches, addresses and masks, routers and gateways, DHCP and DNS. The second teaches a method and practises it on eleven broken networks, up to several faults against the clock. Every step of both courses is proven by the app's self-test. The same day brought a database service with SQL-shaped statements for the architecture lab. More in the Academy

Lab experiments in the window

Load sweeps and studies of the lab for distributed systems now run right in the app, with their charts.

Named runs sit side by side with saturation curves and throughput against latency, and the services of a lab can be set up in forms instead of JSON. The same day brought installing courses, zones and stateful sessions on the firewall models, and quizzes, tests and fault hunts for the academy.

A firewall tab and the academy format

Devices with a firewall get their own tab, and the academy gets the format its courses are written in.

The Firewall tab lists the rules with their hits, the address translations and a test that shows which rule matches a packet, next to the equivalent commands. Also new that day: more device models, choosing the cable first, slim labels, a start page with templates, and CPU and RAM per device.
