WELCOME TO THE FREE, FREE OF CHARGE AND SECURE XMPP/JABBER SERVER
"JABBER-GERMANY.DE" !

Hier geht es zur deutschen Fassung.

!!! Attention !!!

As a current occasion, I ask all users to read this article about the impending
chat control 2.0 - please join!

About:

"jabber-germany.de" provides various services like XMPP, SearXNG, DoH/DoT,
NTP/NTS etc. hosted by myself. The main reason I run these services is because I
like to be in control of my own data where feasible. The easiest way to
accomplish that is to host the services I use. I make them public and maintain
them simply because I want to.

Registration:

Due to the increased incidence of spam messages, a registration is required from
now on. There are two options available:

 1. Send an email to the address below with the desired name to be registered.
    The account will be created as soon as possible and a response with a
    temporary password will be sent. Please use this way in case you want to get
    recovered (or reset) your password at a later stage as this is only way to
    verify you unambiguously.
    
    * EMail address for registration: jomo <at> morbitzer.de
    * PGP/GPG: 4096R/D982BBD6 (12/24/2013)
      
 2. Use the web registration form. Please note that resetting the password with
    this method is not trivial in case of password loss. If in doubt, please
    select option 1 (see above).

I hope for your understanding, the fight against spam has become an important
issue, and this new method of registration finally helps all users.

By using this server to communicate with third parties you agree that data will
be passed to third parties. Messages sent to other users are subject to policies
those users agreed to.

Privacy Policy:

Things that are being stored:

 * User name and hash of password.
 * Offline messages. If someone sends you a message while you are offline that
   message will be stored until you get back online.
 * Archive. By default we will be keeping an archive of your messages for later
   retrieval by yourself. This can come in handy if you log in with a new device
   and want access to your message history and is also required if you want to
   use the OMEMO encryption with multiple devices. You can opt-out of this by
   setting your server-side archiving preferences with your XMPP client.
 * Files. Every file you share with a contact or a conference will be uploaded
   and stored for later retrieval by the recipients.
 * A list of your contacts (Roster, Buddylist). This list is maintained by you.
   You decide who goes on that list and who gets deleted.
 * Semi public data you are publishing for your contacts to see like your avatar
   or the OMEMO public keys.
 * Other private data your XMPP client might upload like a list of conference
   bookmarks.
 * Registering for a push does make an HTTP call which logs a user’s IP
   temporarily, this is necessary for the service to operate.
 * I might activate and keep logs temporarily if this helps mitigating attacks
   (service maintenance).

Things that are not being stored:

 * IP addresses.
 * Any connection and/or duration times.

Remarks:

 * I collect only a minimum amount of information, only what is really needed to
   run my services.
 * Under no circumstances will data be collected, analyzed and shared for
   commerce!
 * And last but not least: I care about privacy on all levels!

DNS, DNS-over-TLS, DNS-over-HTTPS, NTP/NTS, NTFY and SearXNG engine:

The server is running an open, caching-only DNS server as part of the OpenNIC
project and can be used by any user, too, of course. The details are as follows:

   "ikJbw5sG3eVZ7B7os63uqb0B12Qk07E0Tb4pfzrUqhM="
 * DNS-over-HTTPS: https://www.jabber-germany.de/dns-query
 * Limit rates for DoH and DoT: 2000 requests/minute per source IP (with "burst"
   of 50).
 * NTP ipv4: 152.53.15.127#53
 * NTP ipv6: 2a03:4000:6b:191:9825:1cff:fe34:bbe#53

   one recognised (or simply did not let me know), just figured myself ;-) .
 * 2019-06-27: On July, 18th 2019 the server will be down between 11:00h and

   DNS server, filling up the logfiles (some dozend GB), ending up in 100% disk
   space usage. Sorry for that, I assume some people might had issues with XMPP
   the last 12 hours, too. All cleaned up now, and I will reduce the logging
   verbosity of the iptables entries.
 * 2019-01-11: Updated Prosody to version 0.11.2.
 * 2018-11-30: Updated Prosody to version 0.11.1.
 * 2018-11-25: Updated Prosody to version 0.11.0.

   mechanism via email).

   being blocked by some odd firewall rules, like from internet cafes, Free-Wifi
   APs and such).
 * 2018-07-25: Moved Prosody server and all accounts to new server box which is
   more than twice as fast. Upgraded Debian OS, too, during this procedure.
 * 2018-07-12: Added free DNS and DNS-over-TLS services (in addition to the XMPP
   service).
 * 2018-06-01: Update from Prosody version 0.10.1 to 0.10.2.
 * 2018-05-29: MUC service down this morning. New module "mod_vcard_muc" was
   causing the issue, which is disabled for now. Update: Opened a bug report,
   module should be fixed in the meantime. Update: Bug was fixed here
   https://issues.prosody.im/1152.
 * 2018-05-17: Update from Prosody version 0.10.0 to 0.10.1.
 * 2018-01-08: Service was down for an hour due to the Meltdown bugfix (and the
   necessary reboot of the server afterwards).
 * 2017-12-30: Update from 0.9.12 to 0.10.0, including latest module versions
   and omemo_all_access support (alpha release from Daniel G., thanks!!). I wish
   you all the best for 2018...
 * 2017-10-03: 30 minutes outage this morning, did some preparations for the new
   version 0.10, ran one wrong command :-( ... and had to restore some things
   from the nightly backup. Sorry, my bad.
 * 2017-09-27: Will remove XEP-0138 upon the next restart of the server due to
   https://hg.prosody.im/prosody-modules/rev/3092ae96c1f0.
 * 2017-09-18: This morning messages were queued forever at some point, don't
   know what happened. I did install the latest mod_mam.lua last weekend, after
   reverting this module to the previous version and restarting the server the
   messages started flowing again. I need to investigate whether the latest
   mod_mam.lua is/was the root cause of the issue. Update: opened an issue
   ticket at Prosody. Update: Missed a patch in mod_mam.lua, sorry.
 * 2017-08-31: There are rare situations where the Prosody XMPP server is using
   100% CPU time for a longer time period (+10 minutes or so), for no obvious
   reasons, the logfile does not print anything useful at those times, and
   running "perf" on a LUA process isn't helpful either, so I need to start
   debugging things *sigh*. Currently a monitoring tool is restarting the
   process automatically in those rare situations.
 * 2017-08-10: Increased max size for http_upload from 10 to 20 MB and expiry
   from 7 to 14 days.
 * 2017-07-18: This afternoon XMPP clients reported certificate and connection
   errors here and there, happened to me with Conversations, too. It was fine
   again an hour or two later. Don't know what happened, of course problems like
   this always happen while being on vacation :-) .
 * 2017-07-16: The prosody server was looping today, using 100 percent CPU time,
   new connects failed, so I had to do a full restart. I have no idea yet what
   the problem was, the logs don't show anything obvious unfortunately. Update:
   the max amount of file descriptors was reached, I increased the limits
   accordingly, should be fine from now on, sorry for the issue.
 * 2017-06-20: Moved mam storage from RAM to xmlarchive since the memory usage
   of the prosody server constantly increased, causing serious trouble.


HAVE FUN ;-) !!!
