XMPP Service Operators - 2021-03-11

  1. Tim_

    bye bye xmpp, bye bye boese-ban.de

  2. Ge0rG

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

  3. Martin

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

  4. Ge0rG

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

  5. Martin

    Ah Tim_ is the operator Tim Schumacher.

  6. Martin

    Maybe they swallowed the blue pill. 🙄

  7. menel

    With no info whatsoever everything is possible

  8. jayteeuk

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

  9. Martin

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

  10. frog

    > 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

  11. jayteeuk

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

  12. menel

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

  13. jayteeuk

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

  14. neox

    Perhaps OVH-related ?

  15. Martin

    > 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!

  18. menel

    Good afternoon from the old world eastcost dweller 😉

  19. mike

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

  20. 404.city

    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)

  21. Licaon_Kter

    404.city: U ok? Still on OVH?

  22. jayteeuk

    Still morning here, too! Good morning, all!

  23. [czar]

    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.

  28. moparisthebest

    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

  29. Licaon_Kter

    moparisthebest: yes, why not?

  30. moparisthebest

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

  31. moparisthebest

    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

  32. Licaon_Kter

    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

  33. moparisthebest

    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

  34. moparisthebest

    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

  35. moparisthebest

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

  36. moparisthebest

    as a client on any prosody server

  37. Licaon_Kter

    moparisthebest: POC pls?

  38. moparisthebest

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

  39. moparisthebest

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

  40. jonas’

    huh, 512k is not what I’d call a sane stanza size limit

  41. jonas’

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

  42. jonas’

    think base64’d avatars

  43. jonas’

    but yeah, that is very likely to cause fun issues

  44. jonas’

    however, s2s connections are quickly reestablished

  45. moparisthebest

    but messages lost because no sm ?

  46. jonas’


  47. jonas’

    well, no

  48. jonas’

    because both parties know that the stream is being closed

  49. jonas’

    this is different than a broken TCP connection

  50. jonas’

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

  51. moparisthebest

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

  52. shaarad

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

  53. Martin

    Never seen a Mopar.

  54. moparisthebest

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

  55. moparisthebest

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

  56. Martin

    Some foresters or hunters have Ladas.

  57. Martin

    In Kazakhstan I saw a police Lada. 🙂

  58. Wiktor

    moparisthebest: are they really that good?

  59. moparisthebest

    clearly *I* think they are the best :)

  60. Wiktor

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

  61. 4223

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

  62. moparisthebest

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

  63. moparisthebest

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

  64. mjk

    > 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

  65. mjk

    I think Greece isn't a post-soviet country

  66. e2e.ee

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