#Certificate authorities have decided to stop setting the “TLS client” #EKU on the #TLS server certificates they issue.

This immediately created a problem for server-to-server protocols like #SMTP and #XMPP.

Now it looks like XMPP servers have begun to simply ignore their clients' certificates' EKU. https://monal-im.org/post/00016-upgrade-ejabberd-on-debian/

I thought restricting the EKU like this was a bad idea. Looks like I was right. The #CA decision is backfiring.

RE: https://fosstodon.org/@xmpp/116351867577725652

While I don’t use #XMPP systems any more, I am delighted to see all the activity that is happening within the ecosystem!

I was an early user of jabber.org (in the early 2000’s?) and continued to use it until it just got so overrun by spam that it was useless for me. Simultaneously, other places that had been using XMPP systems were all moving to Slack or similar messengers, particularly as independent clients were struggling.

But I have always like the ideas of XMPP… I wish the community well

Great post by @thanosapollo about #Emacs and #Jabber/#XMPP:

https://thanosapollo.org/posts/emacs-jabber-revival/

"Now, jabber.el is the most XEP-complete text-based client in existence."

#mcabber, #poezio, and #profanity get a tough time, I guess.

"Emacs is not just the editor I write jabber.el in. It is the runtime, the test harness, and the application.

I develop in the same instance where I chat. Fix a bug, eval changes, and the fix is live in my running session. Seconds, not minutes."

Life has meaning, again!

Anyone out there that can recommend a good #XMPP / #Jabber client for #iOS that supports multiple accounts and is not Monal?

@FediVideo @thunderbird@tilvids.com @thunderbird@mastodon.online

I'm not sure, if it's appropriate to mention their support for #XMPP. Last time I checked, it was extremely outdated regarding moden #Jabber usage. Many of the features people take for granted nowadays, were not implemented. Did that improve?

Thunderbird is a free open source communications suite including support for email, RSS, XMPP, IRC, Matrix and Usenet. You can follow their official video account at:

➡️ @thunderbird@tilvids.com

There are already over 60 videos uploaded. If they haven't federated to your server yet you can browse them all at https://tilvids.com/a/thunderbird/videos

The only crucial feature, that is still missing for me, so that I finally can ditch #Dino and #Gajim: XEP-0444: Message Reactions (and related, but less essential for me: XEP-0461: Message Replies).

@gusseting

Nice article! Very useful!

I do, however, disagree with @parismarx about Signal and Whatsapp. I never used them and believe we should (try to) avoid them, as they are deeply integrated with #bigTech, i.e. one with AWS,, the other with Meta.

We can use the #fediverse, so let's use federated chat, too! Paris mentions Matrix/Element, which is great. I like to add the founder of federated IM: #Jabber/#XMPP, which exists since 1999.

#digitalSovereignty

Bueno ... tenemos servicio de internerd pero detras de un CGNAT ... imposible hacer que #personal mande un técnico, la zona sigue con problemas, asi que esta esta noche nos saltamos el CGNAT y #cyberdelia vuelve ... estamos tratando de solucionar todo con lo que tenemos a mano, sin un mango porque #argentina y coso, limitando los servicios que damos al máximo, dando solo lo más crítico que es #XMPP ... al menos hasta que nos pasen a fibra, esperemos, veremos que nos depara la suerte.

Wow!

@thanosapollo just released emacs-jabber 0.10.0 with impressive new features:

@untrusted

Only through @thanosapollo I learned about https://github.com/mierenhoop/picomemo

It seems to be a pretty small #OMEMO library in C, supporting both "oldmemo" and "newmemo". Nice!

Will package it for #Debian:

Thanos Apollo (@thanosapollo) added OMEMO support to emacs-jabber (aka jabber.el). You can test it on the master branch here:

Quietly slipped in today: the XSF has published a new XEP - XEP-0512 - which I had the pleasure of authoring.

It's a small step, but one that opens up some interesting directions for #XMPP implementations. Curious to see where people take it from here.

Details: https://xmpp.org/extensions/xep-0512.html

As an aficionado of #tango #dance, music, and lyrics, and also a die-hard #Jabber user, I'm happy about this new #XMPP #standard of today:

XEP-0512: XMPP as Interpretive Dance

https://xmpp.org/extensions/xep-0512.html

I do, however, feel the need for a #protocol #bridge, as the #XEP relies on 4/4, while tango is, as everybody knows, 2/4 (el famoso "dos por cuatro"). Time for #slidge "slango" or "tangidge" maybe?

Actually, even if you don’t care about #UnifiedPush, having this minimal #Prosody server that just accepts messages via a simple REST API and sends them out via #XMPP is great alternative to the various sendxmpp scripts out there.

@thewhalecc

"Unlike other secure messaging solutions, qTox does not require you to be a computer programmer to use it."

Because #Jabber/#XMPP would require a CS master degree? 🤦 Most of my non-techie friends and even the elderly of my family use it without problems.

Anyway, added qTox to my IM chart 🙂

@gajim

Should be in #Debian unstable now, and in #forky #overmorrow.

#Gajim #Jabber #XMPP

@IceWolf @skyweird @gajim

Even with your proposal, a #Jabber client still can just ignore the name in the message and do whatever they want 🤷

I assume, that it depends on the clients DB structure.
Do I have only a simple JID ⇒ nickname table?
Or is it a more complex (JID, datetime) ⇒ nickname table?
Or do I even attach the nickname to every single message?

Changing the #XMPProtocol wouldn't help much.

How hard is it to propose an #XMPP XEP?

Right now it seems name changes are applied retroactively to past messages, or at least Gajim does it that way. This means we can't use our display name to indicate who is talking.

@skyweird::gryphon says that didn't used to be the case when they were using XMPP back in the day? Which means someone came along and fucking changed the semantics of namechanges out from under everyone? (Which by the way, over in Matrix land they're trying to do /exactly/ that. There's a setting to retroactively apply name changes in Element now. It's /on by default/ IIRC. I bet one day they'll remove it.)

We need a way to embed your name into the message itself. That embedded name overrides whatever your global/per-room display name is. Singlets can leave it off and have their retroactive name changes; we can enforce actually seeing our names like they should be.

(Of course it's possible to infer the correct name from the chat history, which is what clients did before, but that's only reliable as long as some jackass doesn't come along and change the semantics out from under you, nuking the names on years of chat history... embedding the name would be a very clear signal "HEY, KEEP THIS NAME".)

I could write up a spec myself if that'd be helpful!

@jackwilliambell

You might like to take a look into #Movim by @movim, if you are interested in the combination of secure chat, public chats, blogging, A/V calls etc.

I looked at Briar some years ago, because I was interested in packaging it for #Debian. IIRC, the protocol wasn't formally documented, so that people could implement it in the programming language of choice, like it is for #XMPP, Matrix etc. Only a Java reference implementation to copy from. I hope, it's better nowadays.

#Jabber

Our combined booth for #UnifiedPush and #XMPP at #CLT2026 went great. There was huge interest in UnifiedPush, and we successfully funneled some of that interest into XMPP as well.
I think it's a great combination since those projects are ideologically well-aligned, and we will likely do it again.

@testman
Saying that Matrix has become the go-to for the FOSS-community does not mean that this is true.

What/where is the source for this statement?

I know projects which use #XMPP and I know projects which use Matrix. I also know projects which use non-federated messengers.

@xmpp_providers
My XMPP server, chat.between-us.online, fell off the Category A list about a week ago, and the reasons I see each day are inconsistent. I also can no longer connect with chat.xmpp-providers.org. I get "Could not authenticate remote servers". Other than this, my server seems to have no problems connecting to any other server, as far as I can tell.

It seems to have happened coincident with getting updated Let's Encrypt certificates.

Let's Encrypt no longer creates dual-use certificates; they dropped ClientAuth from their certificates. I tried switching to ZeroSSL certificates, but they too have dropped ClientAuth.

Is the certificate change coincidental, or do you know if there's another explanation?

If it is the certificates, what do I do? Prosody does not yet have an ability to serve different certificates for inbound and outbound server connections, and so I cannot present a certificate with ClientAuth any longer.

Buem, para terminar la semana, nuestro ISP esta teniendo problemas en la zona, asi que #cyberdelia y nuestros servicios #XMPP y #Mumble estan offline hasta que los vuelvan a conectar con la civilización.

I'm testing #xmpp with #snikket today. It was straight forward to install the server. Like 10minutes. I was very impressed!!

But then the problem started… with #encryption key managment problem.

Basically I wanted to write to a #quicksy user (aka myself) and that didn't work because of some 'Aucun appareil pour qui chiffrer ce message n'a été trouvé. Recherche d'appareils en cours…'

I know that there is a lot of work to improve the situation. I'm open to report bugs, but I have no idea if it should be done in snikket, quicksy, gajim, kaidan …
