hi all
-
arkiver
as noted in #archiveteam , we have had to switch over to ipv6 for rsyncing to the target _for hetzner users_
-
arkiver
i have just released an update for rsync to prefer ipv6 over ipv4
-
arkiver
do note however, that we need ipv4 as well as ipv6, as there are many sites that do not support ipv6 properly
-
arkiver
so we cant have ipv6-only machines unfortunately

rewby: are you implying that i need to setup a special docker bridge or the OOTB config is fine?
-
rewby
Barto: That link's instructions add v6 support to your default docker entwork
-
Barto
so i guess it's a yes :-)
-
rewby
No?
-
rewby
You don't need to setup anything special
-
rewby
Just drop the config lines into the docker config
-
rewby
Restart dockerd
-
rewby
And recreate containers
-
nstrom|m
"out of the box" ipv6 is off on docker in my experience , you do need a little config
-
rewby
Yeah, but you don't need a special bridge tiehr
-
rewby
*either
-
nstrom|m
I will try that config at some point rewby, I have mine setup slightly differently but that way may be more reliable
-
rewby
nstrom|m: There's many ways to do thsi
-
rewby
It depends on your setup
-
rewby
The main reason for doing this is that ipv4 transit is expensive and due to $complexreasons v6 is cheap for this machine
-
rewby
And we are talking at least high triple digits savings.
-
» nstrom|m nods
-
imer
ah, is it a volume discount since the ipv6 header is bigger? /s
-
nstrom|m
wonder if we could/should put something in the grab image logs that says whether or not it's using ipv6 successfully
-
nstrom|m
not that we can really control what rsync says
-
nstrom|m
but otherwise you don't really know since it just "works" either way and looks the same
-
nstrom|m
might help some people if they think it's supposed to be using v6 and isn't for whatever reason
-
rewby
imer: Peering agreements can be funny
-
imer
yeah, is it he?
-
rewby
If you slide alcohol to network engineers you can get a lot to happen
-
rewby
That's all I will say
-
imer
right :)
-
nstrom|m
lol

Barto
rewby: coming back to ipv6, shouldnt that get documented somewhere on the wiki?

Barto: Thanks for volunteering!

Apparently Docker finally figured out how to support IPv6 without experimental mode.
-
JAA
But no idea about the rest either. (I only use Docker on one host anymore, and it doesn't have IPv6.)

» Barto runs away
-
Barto
we'll see when i can do that over the weekend, i have some latency
-
Barto
i already spent my afternoon at work doing some documentation, so what the hell :D
-
JAA
There should also be a short TL;DR version of that page with the important bits how to get up and running. But we can do that once we have the correct current information there.
-
JAA
Would also be good to note which Docker version moved IPv6 from experimental to stable.
-
JAA
I briefly looked for that earlier but couldn't find it.
-
JAA
(Emphasis on 'briefly')
-
JAA
And yeah, writing docs is not exactly fun. :-)

Barto
it only takes 5 minutes for it to become obsolete sometimes
