This is a regression as up till kernel-2.6.18-122.el5, this test never fails. Running the whole Test Suite concurrently in another set of env to confirm the findings. |
Description of problem: NUT did not send NS, but TR1 got NA, please see tcpdump info Version-Release number of selected component (if applicable): kernel-2.6.18-123.el5 How reproducible: everytime Steps to Reproduce: 1. 2. 3.
