Yukiyo-san,I have attached the HTML log file and the Wireshark trace of thetraffic.The test does not fail anymore -- I apologize, it was failing because ofa problem with the NUT.However, the test still does not accept the Router Solicitations thatare sent by the NUT because of their source address.Please advise.Thank you,Peter CarneyDevelopment EngineerTreck Inc.-----Original Message-----From: Yukiyo Akisada [mailto:akisada@tahi.org] Sent: Wednesday, May 07, 2008 2:44 AMTo: Peter CarneyCc: users@tahi.orgSubject: Re: [users:00700] Invalid Source Address of Router SolicitationHi, Peter.Could you show me the actual test log including tcpdump?This might be the bug.Thanks,On Wed, 30 Apr 2008 16:08:40 -0400"Peter Carney" <pcarney@treck.com> wrote:> Hello,> >  > > I am running the IPv6 Self Test version 1.4.14 for hosts and I amhaving> trouble with test number 27: "Global Address Autoconfiguration and DAD> (Host Only)".> >  > > In this test (addr.p2/v6LC_3_2_1.seq) the script waits for a Router> Solicitation from the NUT:> >  > > #----- RA PHASE> vLog("TN received DAD NS from NUT.");> vLog("OK!
