I have been successfully running 9.04 with the ubuntu provided kernels
since its release and haven't seen the problem since.

Hi swmike,

You mentioned you tested an upstream 2.6.27 kernel from kernel.org.
Since this is the case this should really be escalated to the upstream
kernel developers in a bugzilla.kernel.org report.  Care to file this
there as well?  We can then link this bug report to the upstream one.
For more information please refer to
https://wiki.ubuntu.com/KernelTeamBugPolicies#Reporting Bugs Upstream .
Thanks.

[Bug 263260] Re: ipv6 stops working after a while

2008-09-04 Thread swmike
I have now tried kernel.org latest kernels of 2.6.25, 2.6.26 and 2.6.27
and they all have the same problem, I also booted a harlddy installation
with my kernel.org 2.6.26.3, and it had the same problem also.

The weird thing is that I had ipv6 working perfectly with my old hardy
installation (hard drive broke so I had to re-install).

I'm at loss as to what is going on here... No configuration has changed
on the cisco router and it's running a very recent IOS so there should
be no problem there either. I have disabled IGMP snooping on my switch,
didn't change anything either.

I ran the cron script for 14 hours, still worked, then I did the

[Bug 263260] Re: ipv6 stops working after a while

2008-09-02 Thread swmike
I have restarted networking (networking stop && ifconfig eth0 down &&
networking start && killall dhclient && networking reload)

Now everything works again. I have created a cron script that is run
every hour, that pings an ipv6 address. If the problem hasn't occured by
tomorrow again, then it must have something to do with neighbour
discovery from scratch, whether this is in the kernel or it's some
application or firewall that's causing the problem.

MikaelA7200Inf3#show ipv6 neighbors
MikaelA7200Inf3#

No neighbours due to no activity for 8+ hours (I rebooted with
2.6.26-5-generic last night, tried it again this morning (4-6 hours
without activity, still worked, then I tried it now after 8+ hours of
inactivity and it didn't work)) and the status after trying to send
pings from the linux box was the following:

So this problem seems to occur  after more than 6 hours of inactivity
when the ns has completely timeouted, and I'm affected both by
2.6.26-5-generic and 2.6.27-2-generic. I didn't have this problem with a
kernel.org 2.6.26.3 that I compiled myself and ran for 38 days on hardy.

Could it be firewall related? I haven't done any configuration on
anything like Apparmour or anything like that, so I'm running default
settnigs in aspect to any firewall related applications.

I've booted 2.6.26-5-generic now and going to let it run for 24 hours
and see what happens.

IPv6 is working right now after reboot anyway.

Hi swmike,

You commented that you had no issues with a custom compiled 2.6.26.3
kernel.  I'm curious if you were ever able to test a 2.6.26 Ubuntu
kernel from Intrepid?  The reason I ask is I'm wanting to know if this
is specifically a regression with the new 2.6.27 Ubuntu kernel of if it
existed also with the 2.6.26 Ubuntu kernel.  I know the Alpha4 releases
of Intrepid contained a 2.6.26 kernel - http://www.ubuntu.com/testing if
you'd be interested in testing.  Thanks.

[Bug 263260] Re: ipv6 stops working after a while

2008-08-31 Thread Lukáš Vacek
It'd deserve more info from the linux client. Maybe something
interesting in logs, ip -6 n sh, ip -6 r sh, ip -6 a sh

As for me, ip6 works fine with the up2date intrepid but I have stateless
autoconfiguration in my network (radvd running at a router).
