After the arrest of Pavel Durov, I wanted to move from Telegram to something end-to-end encrypted. I know Signal is pretty good, but I think it is better to have our messages in my own server.
I have already looked in XMPP, but it required SSL certs and I did not have the mood to configure them.
Do you know any other selfhosted messaging service for a group of 4-5 friends, or an easy way to configure an XMPP server? Or shall I use Signal after all (I don’t really care that much about being selfhosted, I just thought it would be more privacy friendly)?
UPDATE: I managed to set up an XMPP server using prosody with the SSL certs. We have been testing it with my friend and it seems to go well.
I know, but for some reason my router does not let me access my domain (with duckdns) when connected to my network. So even if I get certs for the domain, I will not be able to access it. I have set up local DNS entries (with Pi-Hole) to point to my srrver, but I don’t know if it possible to get certs for that, since it is not a real domain.
EDIT: Fixed it. (See reply for fix)
So long as your certs are for your fully qualified domain there’s no problem. I do this, as do many people — mydoman.com is fully qualified, but on my own network I override the DNS to the local address. Not a problem at all — DNS is tied to the hostname, not the IP.
I managed to fix this problem by pointing my domain name to my private IP address (with pihole’s local DNS entries), so I could access it. Then, I just got certs for the domain and applied them with nginx.
