XMPP Service Operators - 2021-03-11

bye bye xmpp, bye bye boese-ban.de

Sounds like somebody took my advice "do not run a public server" literally

They're gone? There's no news on the website: https://datenknoten.me/

I don't know how to read that statement in a different way

Ah Tim_ is the operator Tim Schumacher.

Maybe they swallowed the blue pill. 🙄

With no info whatsoever everything is possible

My German isn't strong enough to read the statement, unfortunately. 🙁

> bye bye xmpp, bye bye boese-ban.de No German here except the domain.

> They're gone? There's no news on the website: https://datenknoten.me/ This is in German though. But no word about closing down the service on the main page. Although the registration page is currently 404

The page is still like "you can register here for free..." No info that it is cancelled or why

> No German here except the domain. You don't get redirected to datenknoten.me? ✏

Perhaps OVH-related ?

> You don't get redirected to datenknoten.me? I think Ge0rg referred to this statement > bye bye xmpp, bye bye boese-ban.de As on the website there is no current statement about closing the server or whatsoever.

Good morning fellow xmpp people. I hope you have a wonderful day. Mine is just getting started. 6:25am here!

😃

Good afternoon from the old world eastcost dweller 😉

it's 10:30pm here and I'm about to go to bed. Gnight!

e2e.ee, It is still morning) I prefer to sleep 2 times a day. Imagine that you are asleep, and at this time the server crashes. Yes, this happens, you have two options, go to bed and make you wait for 8 hours or not sleep. sometimes it turns out that you even fall asleep on the keyboard. Someone thinks that you are typing an answer to him, and you are sleeping at this time)

404.city: U ok? Still on OVH?

Still morning here, too! Good morning, all!

Good morning!

PSA: I moved the search.jabber.network crawler to another box. That should not have done any harm, but at the same time, I also automated the installation, so I might’ve missed something. If you note that the listing behaves oddly, feel free to ping me.

does anyone change the default values of max_stanza_size (ejabberd), s2s_stanza_size_limit, c2s_stanza_size_limit (prosody) on their servers ? and if so, to what value and why

moparisthebest: yes, why not?

well "why not" would be breaking federation with other servers I guess

but the reason for the question is it'd probably be good to come up with sane defaults across servers and document it here https://xmpp.org/extensions/xep-0205.html#rec-stanzasize

So who decided BESTest size? https://docs.ejabberd.im/admin/configuration/listen-options/#max-stanza-size https://github.com/processone/ejabberd/blob/master/ejabberd.yml.example#L28-L49

right, and ejabberd's "default" is unlimited, but the value in the example config is much saner, probably more sane than prosody's default of 10M

but depending how errors are handled too (the doc I linked is vague) you could use this to easily permanently break s2s between public servers, as a client

if ejabberd implements stream error on s2s, that means you can break s2s from prosody to ejabberd on all servers today

as a client on any prosody server

moparisthebest: POC pls?

connect to any prosody server, send >512k stanza to someone on an ejabberd server

prosody will accept and send it on, ejabberd will error and probably cut off the s2s connection

huh, 256k is not what I’d call a sane stanza size limit ✏

think base64’d avatars

but yeah, that is very likely to cause fun issues

however, s2s connections are quickly reestablished

but messages lost because no sm ?

yes

well, no

because both parties know that the stream is being closed

this is different than a broken TCP connection

it’s not likely to cause silent message loss; it may cause error bounces depending on whether servers will immediately re-establish the stream

so maybe it's just a resource hog instead of message loss situation which is better, still not ideal

moparisthebest: I have to say that I like your username and profile photo

Never seen a Mopar.

thanks :) yea Mopars seem fairly rare over in euro land

though I once knew a guy in finland that had a really awesome 1968 Dodge Charger

Some foresters or hunters have Ladas.

In Kazakhstan I saw a police Lada. 🙂

moparisthebest: are they really that good?

clearly *I* think they are the best :)

Yes just checking if you didn't change your opinion.. As we know rebranding avatar and well known nicks is quite hard :)

Lada Niwa is cheap and good for offroad. On the road it is a little to noisy inside. And to thursty.

I mean I don't care for any of their new stuff, but their old stuff will always be the best

I had to look up Lada, never seen one of those

> In Kazakhstan I saw a police Lada. 🙂 I'd guess Kazakhstan imports a lot of Russia's stuff, so no surprise there. But I saw a few old ones in Greece

I think Greece isn't a post-soviet country

I saw a taxi... LADA in Bolivia last year. I was in shock.
