| brycec | Well this is odd... IPv6 ssh traffic just broke for me.
ping still works, suggesting something somewhere fucked up with MTUs all of a sudden I still need to dig into this. Just wondered if anyone else was seeing this with ARP? Or a home HE.net tunnel for that matter? | [12:14] | |
| mercutio | i've seen ipv6 mtu discovery not work
have you tried mss clamping? | [12:16] | |
| brycec | mss is clamped as I recall
What's weird is that "everything was working", meaning my SSH sessions were ticking along just fine. Then all of a sudden they hung... but not at the same time. (one hung at 12:09, the other at 12:10 according to the clock in tmux) so *something* *somehow* broke. | [12:21] | |
| mercutio | they hung with large amounts of text?
or typing? hmm my ipv6 tunnel seems to be working normally to arp my tunnel is tserv3.fmt2 | [12:26] | |
| ....... (idle for 33mn) | |||
| brycec | mercutio: Neither. They were both just sitting idle at prompts. Noticed they'd hung when I tried to type, then looked at the clock in my tmux bar on each session and it had frozen. | [13:02] | |
| mercutio | that doesn't sound mtu related
unless something spat lots of text at it it sounds like what happens when something loses state for some reason and is enforcing state. | [13:02] | |
| brycec | More digging later - it's an HE issue and I can't hit anything IPv6 from my home tunnel. http://sprunge.us/TPPC
Reverse mtr from vps3 back towards my home connection showing that it gets lost somewhere within HE http://sprunge.us/JgIR So it's an HE issue -- Sorry for the noise. (The pings as it turns out were hitting the wrong addresses earlier, oops) | [13:06] | |
| mercutio | you're in fmt2 too? | [13:24] | |
| brycec | No? sea1

| .................... (idle for 1h36mn) | |||
| mercutio | hmm i wonder what it is/was | [15:10] | |
| brycec | According to mtr, looks like all is well now. The missing node in both directions was 100ge14-1.core1.pdx1.he.net so I guess they had a brief routing issue.
(or router issue, technically) Side-by-side comparison of mtrs in both directions, before and after http://sprunge.us/UcjD | [15:15] | |

| brycec | LOL nope, no thanks to Netflix.
nathani: Not since Netflix classified HE as a proxy service. | [21:18] | |
