To have access to the internet with your own laptop via the pool computer, you have to connect your laptop with a ethernet cable (which you have to bring yourself) with the ethernet jack next to the computer.
The notebook has to be connected to the ethernet jack before the pool computer is started. Only then the DHCP server will be started, which will assign an IP address to the laptop.
After the you login into the pool computer you have to start the program “/usr/local/bin/activate-laptop” via the command line (e.g. using ALT + F2- → xterm). Only after that step the laptop will be able to access the network.
This step is necessary to track at every point who accesses at which time via which IP.
