Hi,

Iam not getting your problem.

You say that DAD NS is not received, but tcpdump show that DAD NS is
received (15:53:40.131613 :: > ff02::1:ff9e:49b8: icmp6: neighbor sol:
who has fe80::212:79ff:fe9e:49b8)

Can you send the tahi result file.

 

Regards

Ravi Prasad

Hi,

I did the following steps

  1. Make sure the interface of NUT is down.
  2. Run the tcpdump at TN.
  3. Activate the interface of NUT.


NUT configuration
# ifconfig eth2
eth2      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-c8140000


Here is the output of Tcpdump @ TN
# tcpdump -i bge0
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode
listening on bge0, link-type EN10MB (Ethernet), capture size 96 bytes

15:53:40.131599 :: > ff02::16: HBH icmp6: type-#143 [hlim 1]
15:53:40.131613 :: > ff02::1:ff9e:49b8: icmp6: neighbor sol: who has
fe80::212:7
9ff:fe9e:49b8
15:53:40.131618 fe80::212:79ff:fe9e:49b8 > ff02::2: icmp6: router

15:53:40.131623 fe80::212:79ff:fe9e:49b8 > ff02::2: icmp6: router
solicitation
15:53:40.131627 fe80::212:79ff:fe9e:49b8 > ff02::2: icmp6: router
solicitation

Earlier I misunderstood , Now I think NUT is not generating NS.
Is it a bug in the driver?!!

I think my driver name is e1000. 

 


Thanx,
Praveen

Thanks a lot!!
I tried what ever you told to  me, I am getting a single NS and 3 router
solicitations. So looks like driver is perfect.

Thanx,
Praveen

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 IPv6
protocol stack when sending NSs.
