devlug.de is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
Pretty funny that bots are trying to break into my Nginx and TURN services, but absolutely ignore my Prosody service (I have a Jabber server with closed registration for in-family communication).
All unauthorized logins, logins with wrong passwords and attempts to register are logged. But, near half an year I see literally zero attempts to do something like that from bots
Maybe, they are trying to do something on the low level, which doesn't appear on the logs without "debug" level?
"BUT, historic #OMEMO encrypted messages are not available for Dino.
why?"
Isn't that the point of #PFS? Messages are encrypted for this or that device, and if you try to read them with a new device, you can't.
What's probably missing is a standard (#XEP) for synchronizing old messages from one device to another.
For self-hosting, maybe #Snikket by @snikket_im is easier? Never tried it, but it is a dockerized, pre-configured #prosody with all batteries included.
