We run decentralized and federated [https://diasporafoundation.org/ Diaspora] social netowrk, [https://xmpp.org/ XMPP] and [https://matrix.org Matrix] instant messaging services at [https://poddery.com poddery.com]. Along with Diaspora, Poddery username and password can be used to access XMPP and Matrix services as well. [https://chat.poddery.com chat.poddery.com] provides Riot client (accessed by a web browser), which can be used to connect to any Matrix server without installing a Riot app/client.

* [https://prosody.im/ Prosody] is used as the XMPP server which is modern and lightweight.
* This is moved to Durare.org server Virtual Host. See https://gitlab.com/piratemovin/diasp.in/-/wikis/XMPP-durare.org-setup
* Currently installed version is 0.11.2 which is available in [https://packages.debian.org/buster/prosody Debian Buster].
* All XEPs are enabled which the [https://conversations.im/ Conversations app] support.

To load balance between the 2 synchrotrons, We are running [https://github.com/Sorunome/matrix-synchrotron-balancer matrix-synchrotron-balancer]. It has a systemd file at <code>/etc/systemd/system/matrix-synchrotron-balancer</code>. The files are in <code>/opt/matrix-synchrotron-balancer</code>

* Steps for setting up Prosody is given at https://wiki.debian.org/Diaspora/XMPP
* See https://gitlab.com/piratemovin/diasp.in/-/wikis/XMPP-durare.org-setup
# Follow steps 1 to 6 from https://wiki.debian.org/Diaspora/XMPP and then run the following:
mysql -u root -p # Enter password from the access repo
CREATE USER 'prosody'@'localhost' IDENTIFIED BY '<passwd_in_repo>';
GRANT ALL PRIVILEGES ON diaspora_production.* TO 'prosody'@'localhost';
FLUSH PRIVILEGES;
systemctl restart prosody
 
* Install plugins
# Make sure <code>mercurial</code> is installed
cd /etc && hg clone https://hg.prosody.im/prosody-modules/ prosody-modules
 
=== Set Nginx Conf for BOSH URLS ===
* Add the following in <code>nginx</code> configuration file to enable the BOSH URL to make JSXC Working:
upstream chat_cluster {
  server localhost:5280;
}
 
location /http-bind {
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header Host $http_host;
  proxy_set_header X-Forwarded-Proto https;
  proxy_redirect off;
  proxy_connect_timeout 5;
  proxy_buffering      off;
  proxy_read_timeout    70;
  keepalive_timeout    70;
  send_timeout          70;
  client_max_body_size 4M;
  client_body_buffer_size 128K;
  proxy_pass http://chat_cluster;
}
 
* [https://wiki.diasporafoundation.org/Integration/Chat#Nginx See here] for more details on <code>nginx</code> configuration. Alternatively, <code>apache</code> settings can be found [https://github.com/jsxc/jsxc/wiki/Prepare-apache here].

* Manually updating TLS certificate:
===SSL certificate renewal===
letsencrypt certonly --webroot --agree-tos -w /usr/share/diaspora/public  -d poddery.com -d www.poddery.com -d test.poddery.com -d groups.poddery.com -d fund.poddery.com -w /usr/share/diaspora/public/save -d save.poddery.com -w /var/www/riot -d chat.poddery.com
On the 12th of October 2025, all the certificates were removed and were recreated. [https://codema.in/d/XUfAOrPW/poddery-server-certificates-recreated This thread] documents all those steps.
* To include an additional subdomain such as fund.poddery.com use with --expand parameter as shown below
 
  letsencrypt certonly --webroot --agree-tos --expand -w /usr/share/diaspora/public -d poddery.com -d www.poddery.com -d test.poddery.com -d groups.poddery.com -d fund.poddery.com -w /usr/share/diaspora/public/save/ -d save.poddery.com -w /var/www/riot/ -d chat.poddery.com
When renewing certificates on the poddery server, make sure to follow the following steps.
 
# Stop nginx by running
sudo systemctl stop nginx
 
# Renew certificates for all the domains
sudo certbot renew
 
Follow the prompts by certbot to renew certificates for all the domains.
 
# Start nginx after the renewal is successful
  sudo systemctl start nginx
