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: ^^ | 16:56 |
apw | lamont, i have not seen that, i am pretty sure i have a 4.4 but it might be out of date | 16:57 |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 | 16:57 |
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. | 16:58 |
lamont | http://paste.ubuntu.com/26133655/ <-- trace of the packets coming in, INPUT:10 is an ACCEPT on router-advertisement | 16:59 |
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 | 17:01 |
lamont | tbf, that 33:33 dest MAC feels funny to me. | 17:02 |
lamont | The "all nodes" address ff02::1 is converted to 33:33:00:00:00:01. <-- I suspect that comcast is to blame. | 17:05 |
lamont | nm - I'm just failing at reading. it has the right 33:33:0:0:0:1 mac | 17:06 |
lamont | https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1683911 is also somewhat annoying | 17:12 |
ubot5 | Launchpad bug 1683911 in ifupdown (Ubuntu) "ifup places illegally named variables into the environment" [Undecided,New] | 17:12 |
