tooth has joined #arpnetworks 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? mercutio: i've seen ipv6 mtu discovery not work
have you tried mss clamping? 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. 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 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. 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. 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) mercutio: you're in fmt2 too? brycec: No? sea1
*And no, https://tunnelbroker.net/status.php says no issues)
( ***: Lucifer333 has joined #arpnetworks mercutio: hmm i wonder what it is/was 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 mercutio: ahh ***: qbit has joined #arpnetworks

mkb has joined #arpnetworks brycec: LOL nope, no thanks to Netflix.
nathani: Not since Netflix classified HE as a proxy service. ***: awyeah has quit IRC (Ping timeout: 248 seconds)
