[16:56] <lamont> has anyone ran into the ipv6 stack _NOT_ accepting router advertisements despite being told to? (trusty with both 3.13.0-135 and 4.4.0-101)
[16:56] <lamont> apw: ^^
[16:57] <apw> lamont, i have not seen that, i am pretty sure i have a 4.4 but it might be out of date
[16:57] <apw> is this new behaviour
[16:58] <lamont> it's been something that I run into every reboot of this firewall, and then scratch my head for a few minutes, and manually add the router that I SEE ADVERTISING IN TCPDUMP, and then everything is fine unti lthe next reboot
[16:58] <lamont> tbf, it's eth0.55 that the RA is coming in on
[16:58] <lamont> and ip6tables are involved.
[16:59] <lamont> http://paste.ubuntu.com/26133655/ <-- trace of the packets coming in, INPUT:10 is an ACCEPT on router-advertisement
[17:01] <lamont> the upgrade of the kernel to 4.4 was today in a hail-mary attempt -- the box is still running trusty beacuse of other reasons
[17:02] <lamont> tbf, that 33:33 dest MAC feels funny to me.
[17:05] <lamont> The "all nodes" address ff02::1 is converted to 33:33:00:00:00:01. <-- I suspect that comcast is to blame.
[17:06] <lamont> nm - I'm just failing at reading.  it has the right 33:33:0:0:0:1 mac
[17:12] <lamont> https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1683911 is also somewhat annoying
