[13:02:34] <T`aZ> hi, is there any plan for archlinux32 to support aur ? , it seems that for the moment it doesn't work as the original pkg is not compatible with i686 anymore
[13:08:13] <brtln> pass -A to makepkg
[13:08:26] <brtln> archlinux32 doesn't have much to do with aur
[13:08:35] -!- krumelmonster has quit [Ping timeout: 240 seconds]
[13:08:57] <brtln> it's up to respective aur maintainers to keep/add i686 to arch=(), but you should better configure your helper to ignore architecture check altogether
[13:14:07] <T`aZ> i didn't think of that indeed, good idea, thanks :)

[16:34:01] <rewbycraft> deep42thought: I am aware of the issues with the buildserver. Turns out someone hijacked all of OVH's ipv6 space and as a result my dns is a little bit messed up until it can reach everything again. I've sent a few emails to the offenders, and hope to get it all fixed soon.

[16:46:45] -!- hringriin_ has quit [Quit: ^Cc12^CbSee ^Cb^Cc04^Cya^Cc!]
[17:02:21] <tyz> rewbycraft: that sounds awful.
[17:05:20] <rewbycraft> tyz: It seems it only affects you if you have to reach OVH over hurricane electric.
[17:05:36] <rewbycraft> Most home ISPs have alternate ways of reaching OVH, so it's not a big deal to them
[17:05:45] <tyz> ah
[17:05:51] <rewbycraft> But my network can't reach my SBG hypervisor without HE at the moment
[17:06:01] <rewbycraft> So the uplink handling v6 is rip
[17:06:02] <tyz> so someone borked the BGP info?
[17:06:08] <rewbycraft> And so DNS is fucking up as well
[17:06:17] <rewbycraft> Someone leaked some routes into the global routing table.
[17:06:31] <tyz> sounds about right.
[17:06:37] <rewbycraft> Basically told HE "hey, I have direct connection to these networks"
[17:06:44] <rewbycraft> And while I don't doubt that is true
[17:06:52] <rewbycraft> The problem si that you don't tell other networks that
[17:06:56] <rewbycraft> Because they will send traffic to you
[17:07:03] <rewbycraft> In HE's case, *all* OVH traffic
[17:07:08] -!- and has quit [Ping timeout: 268 seconds]
[17:07:17] <rewbycraft> There's a bit more to it
[17:07:23] <rewbycraft> But that's the basic situation
[17:07:40] -!- and has joined #archlinux-ports
[17:07:41] <tyz> I figured. You work at a uni, right?
[17:07:48] <rewbycraft> I don't
[17:07:50] <rewbycraft> I study at one
[17:07:56] <rewbycraft> I work as a software dev
[17:08:00] <tyz> ah. How did you get into this networking stuff?
[17:08:07] <rewbycraft> Personal interest
[17:08:22] <rewbycraft> I've spent entirely too long dicking around with switches and routers.
[17:08:37] <tyz> I've been meaning to learn more in that space, but I don't know a great way to get started without buying equiptment.
[17:08:56] <rewbycraft> Learned BGP at DN42, then was taught some useful things by industry veterans. Then started my own public network/ISP
[17:09:04] <rewbycraft> tyz: Look up GNS3
[17:09:19] <rewbycraft> It's basically virtualised routers of various branks
[17:09:20] <rewbycraft> *brands
[17:09:34] <rewbycraft> Not very performant (don't expect more than a few mbps of throughput)
[17:09:39] <tyz> hmm. I'll definately check that out.
[17:09:41] <rewbycraft> But it's a great way to experimetn and learn
[17:09:44] <tyz> definitely*
[17:09:54] <rewbycraft> If you wanna start messing with BGP and such, look up wiki.dn42.us
[17:10:26] <rewbycraft> Once you have a bit of a grasp on routing, dn42 is a great place to put it into "practice" using a virtual network intended for learning
[17:11:23] <tyz> nice
[17:15:03] <tyz> rewbycraft: Is it possible to publish a bgp route publicly saying "I've got a connection" but only take a portion of the traffic? Or is the route all-or-nothing?
[17:31:27] -!- deep42thought has joined #archlinux-ports
[17:33:55] <rewbycraft> tyz: That's not how it works at all
[17:34:05] <rewbycraft> tyz: As I said, learn about routing using gns3, then it will make sense
[17:34:58] <rewbycraft> tyz: Also, read this: https://community.brocade.com
[17:35:01] <phrik> Title: Brocade IP Primer eBook - Download Now! - Brocade Community Technical Support Forums - 2905 (at community.brocade.com)
[17:35:11] <rewbycraft> It's a great free ebook for a primer on this stuff
[17:35:18] <rewbycraft> They use a lot of brocade gear as example
[17:35:22] <rewbycraft> But the concepts are explained well

[19:34:44] <rewbycraft> deep42thought, tyz: Looks like it's fixed.
[19:34:56] <rewbycraft> I fired off a few emails to the offending ISPs and they fixed it
[19:43:26] -!- abaumann has joined #archlinux-ports
[19:44:40] <rewbycraft> Hey abaumann
[19:44:57] <abaumann> hi there :-)
[19:45:22] <rewbycraft> Just FYI: the buildmaster should be back online properly.
[19:45:27] <rewbycraft> Had some... interesting network issues
[19:45:50] <abaumann> ah. network problems are always interesting. :-)
[19:46:10] <rewbycraft> Some ISP hijacked all of OVH's ipv6 across a few transits
[19:46:23] <rewbycraft> A few emails took care of it
[19:46:41] <abaumann> ipv6, far too modern for me. :-)
[19:46:49] <abaumann> I'm still sticking with IPV4
[19:47:21] <rewbycraft> Heh. In my case, the sbg hypervisor needs ipv6 to have working internet
[19:47:30] <abaumann> fair enough.
[19:47:49] <rewbycraft> The router backhauls to my frankfurt router via v6 because OVH's IPs are a) expensive b) flaky
[19:48:24] <rewbycraft> And I have a /48 just on the frankfurt router for that backhaul
[19:48:35] <rewbycraft> But that path needs to run over one of the affected networks
[19:48:43] <rewbycraft> So everything kinda died
[19:49:06] <rewbycraft> It tried to go via spain, which isn't very productive when trying to get from germany to france
[19:49:16] <abaumann> :-)
[19:49:19] <rewbycraft> (And then got lost in spain)
[19:52:54] <brtln> only recently any traffic from my home in Poznan to Warszawa was going through UK
[19:53:08] <brtln> Poznan and Warszawa are maybe 300km away from each other
[19:53:12] <brtln> 10/10
[19:53:16] <rewbycraft> But was it still going where it was supposed to be going?
[19:53:28] <brtln> yeah, at least it was arriving fine :)
[19:53:36] <rewbycraft> Then what you experienced was very different
[19:53:45] <rewbycraft> You experienced a breakdown in interconnectivity between two network
[19:53:56] <rewbycraft> And their routers they re-routed the traffic to the nearest intersection
[19:53:59] <rewbycraft> Which apparently was the UK
[19:54:00] <brtln> oh, it wasn't a breakdown at all
[19:54:06] <brtln> it was deliberate route set by ISP
[19:54:12] <rewbycraft> >.>
[19:54:22] <rewbycraft> I like to assume things breaking above stupidity
[19:54:47] <brtln> it was stupidity, I went through all AS to see if there was a better route available
[19:54:50] <brtln> and they just didn;t use it
[19:54:53] <rewbycraft> ...
[19:55:05] <brtln> I lost my faith then
[19:55:07] <rewbycraft> In this case, it was an ISP leaking routes from what I imagine was an IX peering
[19:55:13] <rewbycraft> * to Hurrican Electric
[19:55:43] <rewbycraft> And from HE a few other networks, mine included, got rerouted to the ISP's routers
[19:55:47] <rewbycraft> Where a firewall or something killed it
