Advanced Testing Network Testing Network, or, Das Unternet

• In order to securely test network devices in Advanced Testing, we've set up a secure network with minimal services to verify that devices such as switches, wireless access points, and routers work without exposing our main network to untrusted devices.

• Services on Das Unternet are provided by the virtual machine "drydock," and the network is 10.4.4.0/24. The services provided are DHCP and an httpd server on 10.4.4.1 ("drydock")/

• To troubleshoot, plug a laptop with a known working ethernet port into the Das Unternet jack in Advanced testing. make sure you obtain a DHCP lease in the 10.4.4.0/24 network, then navigate to http://10.4.4.1/ and look for the "It Works!" page. If these steps work, then the fault does not lie with Das Unternet, but rather with whatever device is being tested.

• Possible points of failure:
  • the cable from Advanced Testing is plugged into the wrong network
  • drydock's host machine is plugged into the wrong network (ask a Technocrat)
  • drydock's host machine has a bad network card (ask a Technocrat)
  • drydock is offline (ask a Technocrat)
  • the web server may not be running (ask a Technocrat, and remind them that drydock is running nginx if they get frustrated)
