Glad you're ok Neustradamus, we missed you :)

😁

xmpp.org and all up to date Prosody servers should have no problems with jabber.org now, as far as I know

It doesn't as far as I can tell.

F2F XMPP Meetup tommorow in Hamburg, Germany in case somebody does some Corona traveling by coincidence ...

I'm kinda interested myself ✏

> xmpp.org and all up to date Prosody servers should have no problems with jabber.org now, as far as I know So migration had been completed?

No, up to date Prosody has a tweaked cipher preference and shouldn't have problems.

Oh, sorry. My mind doesn't see a difference between xmpp and jabber. Kind of an important distinction when referring to domain names though. 😉

jabber.org ←→ xmpp.org (including muc.) works fine from what I can tell

Nevermind, I took Matt's response as a "this was already done". Clearly, I was not paying enougt attention.

Haaaargh. I can't type or click today.

And here the Link to the Movim Announcement of our Hamburg Meetup tomorrow: https://nl.movim.eu/?node/pubsub.movim.eu/de-hamburg-xmpp-meetup/xmpp-meetup-in-hamburg-september-20th-202014h-l3YCrR

Guus, jij wilt zeker straks in de trein stappen en erbij zijn, niet waar? Dan kan je ook weer klicken en typen van zo veel euphorie ... :D

MattJ, I still see pings to jabber.org fail from some xmppobserve probers

jabber.org → jabber.de also fails (maybe the reverse direction, I can't tell)

MattJ, one of them prominently being my own ;)

I suspect they may have set a custom cipher string, which ends up preferring DHE and then they get that 1024bit DHE problem

DH key too small

no custom cipher strings

but prosoy 0.11.2-1 (debian buster)

so maybe that doesn’t qualify as "up to date"

the other failing one is, I think, the one from mdosch ✏

The ECDHE > DHE string is default in 0.11.6

Earlier has DHE > ECDHE but with DHE disabled, intended to only be preferred if enabled by setting DH params.

Buuuuut if the remote has DHE enabled with small DH params... this happens.

I see

so I’d have to backports

Stupid question (but serious), and I know I dont have technical understanding, why is it so hard to get jabber.org get running? I mean from your side and your knowledge 😅

MattJ: I confirm that the problem is always here

A jabber.org user can join this mucroom and will be kicked one second after.

jabber.org can't cope with the nick Rixon 👁🗨

isn't jabber.org still running M-Link? ✏

Its the fifth entry if I search "jabber" in my search engine. I count it as important thereby

Future version of Prosody won't allow 👁🗨 or robot face in nicknames, thus solving that problem.

Zash, nooo

is that like no non-ASCII whatsoever or just no emoji

I don't wish to spend the night crying under my desk so I shall not discuss this. Short version is to be strict on validity when local resources are created. Usernames, MUC nicknames must comply with the relevant validation profile.

Zash, reasonable; will go rtfm :)

More like read mailing list threads and issue tracker, tho I guess an RFC or five are relevant
