I happen to be pretty happy with openwrt and dd-wrt at this point, as regards to ipv6 support. One favorite feature for me is that they use source specific routing for ipv6, which is an elegant solution to the bcp38 problem ipv4 has. default from 2601:never:you:mind:6fe3 via fe80::22e5:2aff:feb8:14f dev eth0.2 proto static metric 512 pref medium default from 2601:never:you:mind::/60 via fe80::22e5:2aff:feb8:14f dev eth0.2 proto static metric 512 pref medium with no other default route in place, nothing escapes. Others include autoassignment of ipv6 prefixes across interfaces, dnsmasq naming for slaac, pretty good set of default fw rules, wireguard, sqm etc, etc. And they've always supported every ipv6 tunneling method there was, if you can't go native. > Regards, > > Peter Tiggerdine > > GPG Fingerprint: 2A3F EA19 F6C2 93C1 411D 5AB2 D5A8 E8A8 0E74 6127 > > > On Mon, Apr 20, 2020 at 3:31 PM Karl Auer wrote: >> >> On Mon, 2020-04-20 at 05:07 +, Mark Delany wrote: >> > FWIW, I've never touched jitsi before in my life but even I managed >> > to follow a cookbook and get a dual-stack server up and running in a >> > few hours.

Re: [AusNOG] My condolences to the people trying to sort out remote learning
> The problem is and always has been NAT. You need an external rendezvous Makes you wonder why more Australian RSPs don't do ipv6. Unfortunately all those RSPs who are still v4-only have missed the boat and now their customers will feel a lot more pain over the coming months than customers on a dual-stack RSP. Churning is pretty easy if you're on the NBN. Just sayin. And for those of you setting up your own jitsi servers or similar, of course you'll deploy on a dual-stack server to maximize the prospect of your users/customers getting a better experience. Yes? FWIW, I've never touched jitsi before in my life but even I managed to follow a cookbook and get a dual-stack server up and running in a few hours. I was tempted to drop the A RR just to see how many users would squeal, but that would be too cruel in Australia.

There's interesting comments on audio quality in https://github.com/bigbluebutton/bigbluebutton/issues/7007 which I haven't had time to dive in to. Our music teachers mostly complain that the audio cuts out during loud or staccato periods. And thanks Rob for the kind words. Our go live for remote learning was a few weeks ago, and despite several tests 4 separate components fell over due to excess load. It was a stressful morning alright, but I sat back, took a breath and worked on them one-by-one and everything was running smoothly within a day, and now the teachers are loving it.

[AusNOG] My condolences to the people trying to sort out remote learning
I'm watching my wife and her friends on derpbook try to consolidate their tech support hints and tips to get the rugrats onto and into Day 1 of their remote learning, and the last thing she sent to me was 'High school has fully crashed'. I understand that all your stuff is on fire, and everything that was on fire yesterday is now a towering inferno, and you probably feel like everyone is blaming you. Please don't stress. If you have someone breathing down your neck, here's a bunch of technically correct, but also useless excuses you can give people to get them off your back for a while, while you actually fix the problems that have cropped up without having to explain them to a non-technical audience. 1. There are IPv6 problems (you can grow this one out as much as you want. Blame NAT64) 2. We aren't receiving all of AARNET's BGP announcements (bonus points are awarded if you're not MEANT to be receiving AARNET's BGP announcements, but still manage to use this as an excuse) 3. Some of our peering links are down (Well, you can't use that if you REALLY have all your peering links up, but who is in that state right now??) 4. Office365 is playing up _or_ Office365 has just started working (You can alternate this one, to match reality) 5. There's congestion on the Telstra network (Don't be specific as to WHERE the congestion is) 6. Have you checked YOUR firewall? No, really. Check it again. (Repeat several times) 7. Wildcard! Blame VoIP. SIP is so complex, most people will glaze over when you start explaining that the SDP is being mangled incorrectly so RTP is leaving bogus port forwarding in place in your border NAT device which ... blah blah. But here's the important thing. This is not the end of the world. If stuff is down because of something out of your control, or because you're busy putting out other fires, IT DOESN'T MATTER. Here's a photo of my pair not CARING that everything is broken. https://i.imgur.com/jBXrE9M.png They're the end users, they don't care. No matter who is saying it's a life and death thing, it's not. There ARE things that are life and death (eg, 000/VoIP!). Care about those. And geez, if you REALLY get stuck with something that you think that you should be able to figure out and can't, post it here. We don't mind. Got a VOIP problem? Ask me here, or off list. BGP Filters not working? Routing loops? Whatever. Post it here. (Except, possibly enough of the 'Office 365 CDN is corrupt' stuff, because this is something that Microsoft REALLY SHOULD have solved by now) I always find that even just talking about, or writing down, a problem that has stumped me always helps (see 'Rubber Duck Debugging'). Half of us are sitting around twiddling our thumbs because we've got 50% of our normal traffic, and I'm sure we'll all be willing to help. --Rob PS: I honestly, truly, care.
