Make sure the interface of NUT is down. 2. Run the tcpdump at TN. 3. Activate the interface of NUT.NUT configuration# ifconfig eth2eth2 Link encap:Ethernet HWaddr 00:12:79:9E:49:B8 inet6 addr: fe80::212:79ff:fe9e:49b8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:55 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:4402 (4.2 KiB) Base address:0x8040 Memory:c8120000-c8140000Here is the output of Tcpdump @ TN# tcpdump -i bge0tcpdump: verbose output suppressed, use -v or -vv for full protocoldecodelistening on bge0, link-type EN10MB (Ethernet), capture size 96 bytese1000: eth2: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex15:53:40.131599 :: > ff02::16: HBH icmp6: type-#143 [hlim 1]15:53:40.131613 :: > ff02::1:ff9e:49b8: icmp6: neighbor sol: who hasfe80::212:79ff:fe9e:49b815:53:40.131618 fe80::212:79ff:fe9e:49b8 > ff02::2: icmp6: routersolicitation15:53:40.131623 fe80::212:79ff:fe9e:49b8 > ff02::2: icmp6: routersolicitation15:53:40.131627 fe80::212:79ff:fe9e:49b8 > ff02::2: icmp6: routersolicitationEarlier I misunderstood , Now I think NUT is not generating NS.Is it a bug in the driver?!!I think my driver name is e1000.

So looks like driver is perfect.Thanx,Praveen-----Original Message-----From: Mitsuru Chinen [mailto:mitch@jp.ibm.com <mailto:mitch@jp.ibm.com>]Sent: Thursday, September 22, 2005 7:30 PMTo: users@tahi.orgSubject: [users:00121] Re: IPv6 Conformance Test For Stateless AddressConfiguration - Failing why!!Hi,Lobo, Praveen Rajesh (STSD) wrote:> But the all est cases related to Stateless Address Configuration are> failing because of NUT , which is not transmitting any DAD NSpackets.> I observed in tcpdump, NUT is not at all generating any packets> during execution of these test cases.> > Should I need to do any configuration in linux to enable DAD packet> generation?No, you don't need to do any configuration.Why don't you try the simple check without TAHI?Namely, 1. Make sure the interface of NUT is down. 2. Run the tcpdump at TN. 3. Activate the interface of NUT.If you cannot see any NSs, you may doubt the network driver.I heard there were a few drivers which have a bug, they disturbed IPv6protocol stack when sending NSs.Best Regards,,----Mitsuru Chinen <mitch@jp.ibm.com>124_2.html (attatchment)(tag is disabled)
