Description Tobias Wenzel

2020-07-14 11:33:24 CEST

The test 22_computerroom_wakeonlan.py checks if WoL signals can be sent to 255.255.255.255 or other subnet addresses (see Bug #51074). 
To implement this, the tshark output is greped for the mac of the client, which the signal is being sent to. Since tshark takes some time to start, this is done multiple times. This is most likely the problem, but I couldn't fix it so far.

The test passes on my VM, but remains flaky on jenkins. I set the flag to SKIP-UCSSCHOOL for now.
