I upgraded from 2.4.3 to 2.4.6 two days ago, and suddenly get
message like this:
Jul 5 19:05:51 thunderbird kernel: ICMP NDISC: fake message with
non-255 Hop Limit received: 249
Jul 5 19:05:53 thunderbird last message repeated 2 times
Jul 5 19:07:16 thunderbird last message repeated 20 times
Which seems to go on for about 4 minutes.
Then:
Jul 6 06:38:18 thunderbird kernel: ICMP NDISC: fake message with
non-255 Hop Limit received: 250
Jul 6 06:38:37 thunderbird last message repeated 8 times
Jul 6 07:13:49 thunderbird kernel: ICMP NDISC: fake message with
non-255 Hop Limit received: 250
Jul 6 07:13:51 thunderbird last message repeated 2 times
Jul 6 07:19:28 thunderbird kernel: ICMP NDISC: fake message with
non-255 Hop Limit received: 250
Jul 6 07:19:55 thunderbird last message repeated 8 times
Which went on until 7:39
I also see alot of "ICMPv6 checksum failed", which seem to come
from the same source most of the time. I did get those before,
maybe it's related?
Is this a bad thing? Can I do something to help debug this?
This box is mostly doing IPv6 traffic. The counter says we
received 433 MB and send 338 MB of ipv6 trafic so far during the
last 2 days, which is about 2.4 KB/s receive, and 1.9 KB/s send.
Please CC me, as I'm not on the list.
