XMPP server (Gajim, OMEO encryption, ejabberd .onion setup)

Initial Setup

First let's install the required packages, and then run the xmpp server using docker (you can check the documentation here), we'll follow Lukesmith's tutorial specifically:


apt install ejabberd -y

Now we need the following domain names to point to your server:


    datura.network - Your XMPP hostname
    xmpp.datura.network - For mod_muc, Multi User Chats (MUCs)
    upload.datura.network - For mod_http_upload, file upload support
    proxy.datura.network - For mod_proxy65, SOCKS5 proxy support
    pubsub.datura.network - For mod_pubsub, publish-subscribe support (A fancier RSS)

Then we edit the ejabberd config file accordingly:


[ Datura ] [ /dev/pts/10 ] [/srv]
→ vim /etc/ejabberd/ejabberd.yml

[...]

hosts:
  - datura.network

[...]

  mod_muc:
    host: xmpp.datura.network

[...]

Next we need to obtain the TLS certificate for the xmpp.datura.network domain, to do so we'll use acme.sh:


[ Datura ] [ /dev/pts/10 ] [~]
→ systemctl stop nginx ; acme.sh --issue --standalone -d xmpp.datura.network -k 4096 ; systemctl start nginx

[Sun Jun  9 07:12:39 PM CEST 2024] Your cert key is in: /root/.acme.sh/xmpp.datura.network/xmpp.datura.network.key

[Sun Jun  9 07:12:39 PM CEST 2024] And the full chain certs is there: /root/.acme.sh/xmpp.datura.network/fullchain.cer

[ Datura ] [ /dev/pts/10 ] [~]
→ chown -R ejabberd:ejabberd /root/.acme.sh/xmpp.datura.network

[ Datura ] [ /dev/pts/10 ] [~]
→ cat /etc/ejabberd/ejabberd.yml

[...]

certfiles:
   - "/root/.acme.sh/xmpp.datura.network/fullchain.cer"

[...]

Then we add the admin user in ejabberd.yml:


[ Datura ] [ /dev/pts/10 ] [~]
→ cat /etc/ejabberd/ejabberd.yml

[...]

acl:
  admin:
     user:
       - "nihilist"

[...]

We also add the File Uploads:


[ Datura ] [ /dev/pts/10 ] [~]
→ cat /etc/ejabberd/ejabberd.yml

[...]

  mod_http_upload:
    put_url: https://@HOST@:5443/upload
    docroot: /srv/xmpp/upload/
    custom_headers:
      "Access-Control-Allow-Origin": "https://@HOST@"
      "Access-Control-Allow-Methods": "GET,HEAD,PUT,OPTIONS"
      "Access-Control-Allow-Headers": "Content-Type"

[...]

[ Datura ] [ /dev/pts/10 ] [~]
→ mkdir /srv/xmpp/upload/ -p

[ Datura ] [ /dev/pts/10 ] [~]
→ chown -R ejabberd:ejabberd /srv/xmpp/upload/

We enable message archives too:


[ Datura ] [ /dev/pts/10 ] [~]
→ cat /etc/ejabberd/ejabberd.yml

[...]

  mod_mam:
     ## Mnesia is limited to 2GB, better to use an SQL backend
     ## For small servers SQLite is a good fit and is very easy
     ## to configure. Uncomment this when you have SQL configured:
     ## db_type: sql
     assume_mam_usage: true
     default: always

[...]

Next, you setup a coturn service for the VOIP here, but in this case we'll use the same coturn service that we previously setup for the matrix server


[ Datura ] [ /dev/pts/10 ] [~]
→ cat /etc/ejabberd/ejabberd.yml

[...]

  mod_stun_disco:
    secret: "DAWDDWADWADAWDWAWDDWAADWADWDWADWADWAAWDDWAWAD"
    services:
      -
        host: m.datura.network
        type: stun
      -
        host: m.datura.network
        type: turn

[...]

Then we restart the ejabberd service:


[ Datura ] [ /dev/pts/10 ] [~]
→ systemctl restart ejabberd

[ Datura ] [ /dev/pts/10 ] [~]
→ systemctl status ejabberd

Now that the ejabberd service has restarted successfully, we can register the admin user:


[ Datura ] [ /dev/pts/10 ] [~]
→ ejabberdctl register nihilist datura.network P@SSW0RD

User nihilist@datura.network successfully registered
