Understanding messaging protocols: XMPP and Matrix

So far I have set up an xmpp account. It is impressive but I have come up with only a few others who use it.

We are getting close to having half of Russia onboarded to #Quicksy and me going broke on SMS fees. привет, I guess 👋🇷🇺

I was a bit silent the past few days. It's because I was focusing on improving and fixing many features related to Spaces in Movim 😁

Notifications and message counter are now correctly working in Spaces 🔔✨ Some other issues, related to performances and navigation were also fixed along the way 👀

There is also a totally new flow when adding a chatroom or answering an invite. Movim will try to know if the room you are joining is valid and gives you hints about it before adding it to your bookmarks ℹ️

I'm planning a new release in the upcoming weeks with all those exciting new features in it 😉

Enjoy!

We have released version 5.0.4 of Openfire, our #XMPP-based, open source, real-time communications server! This is a bugfix release, that will increase stability of our 5.0 branch while we finalize work on an upcoming 5.1.0 release. Read more in our blogpost! https://discourse.igniterealtime.org/t/openfire-5-0-4-release/96411

what is the state of bridging data between XMPP/Jabber and Matrix?
both from a server operator perspective but also a user

@dino @debian

For the brave people, who are running #Debian testing or unstable, there is also #Dino from #experimental. It's the latest git master. Works for me, but don't complain when it eats your hamster!

#Jabber #XMPP

@nivex

For me it's #Jabber/#XMPP for all private chats and some public channels:

https://search.jabber.network/

Also both IRC (thanks to the #biboumi bridge) and Matrix (thanks to the #slidge bridge) for various public channels.

Haven't used my Matrix account in about a month. Most of my chatter is on Signal or #XMPP now.

@pwob

Thanks to @mailbox_org for including #Jabber/#XMPP in their services!

Dear users of #Dino on #Debian: You might like to use dino-im 0.5.1-1~bpo13+1 from #trixie-backports, which has improvements over 0.5.0-1 in stable.

@freekkettone unico neo: tra le opzioni per la messaggistica non c'é #xmpp !!!

In case you're using the official ejabberd packages on Debian stable: They're affected by a recent CA policy change (e.g., Let's Encrypt), causing ejabberd to reject newly issued certificates and thereby breaking federation with some remote servers. Deploy this update to fix the issue:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1128568#23

You may also want to consider enabling mod_s2s_dialback to deal with remote servers that haven't been updated yet.

Working on a proof-of-concept bridge from #DMR SMS to #XMPP chat and vice-versa.

Below demo uses a Hytera HP785 DMR radio and a PinePhone with Dino as messenger software.

Still have alot to learn about XMPP and various XEP (protocol extensions).

#Matrix ist für mich gestorben. Ich werde meine Instanz wohl noch etwas laufen lassen, allerdings mir das ganze System zu kompliziert:
Ich war bis letzte Woche im @gnulinux Talk. Das lief auf meinem ("einfach zu installierendem") matrix-synapse auch mit meinem XMPP-Transport (Element ist mir zu behäbig, ich mags einfach nicht!) mit, ab und zu gab ich mal meinen Senf dazu, okay. Nun wurde das auf eine ominöse "Raum V12"-Version (??) geupdated - bei mir gehts nicht. Immerhin hat man seitens Gnulinux nachgeschaut, was los ist - heraus kam: geht nicht mit meinem Matrix-Synapse. Man gab mir außerdem zu verstehen, daß das Matrix-Synapse nicht so gut wäre. Ich bin nur user, aber ein user, der seit 2008 seinen eigenen #XMPP-Server am laufen hat. Gegen Matrix ist das ein Kinderspiel, muß ich feststellen - bzw. die Workarounds sind gut/besser dokumentiert.
Insgesamt ist Matrix aus meiner Sicht zu kompliziert, zu behäbig, für mich halt unpraktikabel.

Ich habe ein kleines Update von https://imday.de/ vorgenommen.

Vorher musste man entscheiden, ob man seine Telefonnummer verwenden möchte. Das fällt nun weg.
#Quicksy wird nur noch im jeweiligen Zielrezept als mögliche Vereinfachung geführt.
Man soll somit stärker ermutigt werden, bewusst und souverän eine Adresse anzulegen.

#xmpp #did #dut

https://imday.de/en/ has been updated.

You do not need to decide anymore whether you want to use your phonenumber.
The option to use #Quicksy is only mentioned as an alternative in the recipes for mobile phones.
The idea of this change is: encouraging the reader to create an own phonenumber-independent address.

#xmpp #did #dut

Something @larma and I have been working on during the #IETF125 Hackathon in Shenzhen:

Dino (@dino) and #Conversations_im can now give you a little warning if it's currently the middle of the night for the contact you are chatting with.

Nuevo server uruguayo de mensajería XMPP.

Si bien está funcionando desde el 1 de noviembre, es la primera vez que le "doy pa delante" aquí, ya que considero esta lo suficientemente "maduro" como para dejarlo crecer.

🚧 trashserver.net: Our file upload server has been switched to a new, experimental server software (developed by me, @thomas).

If you experience any issues with file uploads, let me know.

#trashserver #xmpp #ejabberd #rustyFiler

Not sure why I did this, but ejabberd works fine on my gen 1 raspberry pi (14 years old, 512mb RAM). Would probably enough to handle a small instance for friends and family.

The new official Movim stickers pack is out, with our two new mascots in it! 📢

You can already try it out on https://mov.im/ 😸

The stickers are made by the very talented Rimou (https://lematougraphe.fr/) ✨

And one new tiny feature, you can now quick-search for connected users in large chatrooms 👀

I recently added a display to #Conversations_im showing the number of stanzas (XMPP packets) sent/received in the current session. What are your counts and how long has your session been active? (Account Details -> 'Server info' in the overflow menu.)

New Movim stickers

Yesterday, I quickly put together a tutorial on how to replace ntfy.sh with a minimal, self-hosted XMPP server and published it as a GitHub Gist. Then I remembered I have a website and reworked it into two nice little posts:
https://gultsch.de/tags/ntfy.sh/

#ntfy #XMPP #Jabber #Prosody

Did you know that most Android #XMPP apps also work as a #UnifiedPush distributor and thus can easily replace apps like #ntfy (recently became vibe-coded) for this? Find our tutorial here: https://joinjabber.org/tutorials/service/unifiedpush/

We will have a combined #XMPP and #UnifiedPush stand at #CLT2026 on March 28th and 29th. Come talk to us if you are curious about either! We will have merch for both, test devices, lots of advice, and I've even heard rumors about free Haribo.

RE: https://mastodon.social/@fediversereport/116178002926045553

That's exactly why having a standard that covers all the interactions, clients and servers is primordial.

https://connectedplaces.online/reports/fr156-share-where/

Movim "API" is XMPP, Mastodon API is Mastodon API, developped by Mastodon and for Mastodon. Only the servers to servers interactions are standardized and specified in ActivityPub.
