description |
While running certification test under 18.04 beta release, encountered persistent Ethernet Device test failure. All NIC cards either 1G or 10G Ethernet/SFP are failing Multi-NIC Iperf3 stress testing. At IPERF server, a message “the client has terminated” will pop out on screen. Even though the NIC interface did not lost connection because it still responds to a ping command as seen from IPERF server. The testing will not continue and it will terminate unexpectedly. This error always happened during Test No. 2 – when testing the 2nd port connection of any NIC cards (either 1G or 10G interfaces). IPERF output as follows:

Revised bug description
-----------------------
If a server test run is initiated via an SSH login, and if that login is terminated, the test run will also be terminated. This is a common occurrence when running network tests, and sometimes also CPU stress tests. Our workaround to this to date has been the "screen" utility, which maintains a terminal session even if the SSH connection is broken. Running the tests at a physical or KVM terminal also bypasses the problem. Better robustness to an SSH session breaking is desirable in case the user forgets to use "screen," though.
