-- Prosody XMPP Server Configuration
--
-- Information on configuring Prosody can be found on our
-- website at https://prosody.im/doc/configure
--
-- Tip: You can check that the syntax of this file is correct
-- when you have finished by running this command:
--     prosodyctl check config
-- If there are any errors, it will let you know what and where
-- they are, otherwise it will keep quiet.
--
-- Good luck, and happy Jabbering!


---------- Server-wide settings ----------
-- Settings in this section apply to the whole server and are the default settings
-- for any virtual hosts

-- This is a (by default, empty) list of accounts that are admins
-- for the server. Note that you must create the accounts separately
-- (see https://prosody.im/doc/creating_accounts for info)
-- Example: admins = { "user1@example.com", "user2@example.net" }
admins = { }

-- This option allows you to specify additional locations where Prosody
-- will search first for modules. For additional modules you can install, see
-- the community module repository at https://modules.prosody.im/
--plugin_paths = {}

-- This is the list of modules Prosody will load on startup.
-- Documentation for bundled modules can be found at: https://prosody.im/doc/modules
modules_enabled = {

	-- Generally required
		"disco"; -- Service discovery
		"roster"; -- Allow users to have a roster. Recommended ;)
		"saslauth"; -- Authentication for clients and servers. Recommended if you want to log in.
		"tls"; -- Add support for secure TLS on c2s/s2s connections

	-- Not essential, but recommended
		"blocklist"; -- Allow users to block communications with other users
		"bookmarks"; -- Synchronise the list of open rooms between clients

		"admin_adhoc"; -- Allows administration via an XMPP client that supports ad-hoc commands
		"admin_shell"; -- Allow secure administration via 'prosodyctl shell'

	-- HTTP modules
		--"bosh"; -- Enable BOSH clients, aka "Jabber over HTTP"
		--"http_openmetrics"; -- for exposing metrics to stats collectors
		--"websocket"; -- XMPP over WebSockets

	-- Other specific functionality
		--"announce"; -- Send announcement to all online users

		--"tombstones"; -- Prevent registration of deleted accounts
		--"watchregistrations"; -- Alert admins of registrations
		--"welcome"; -- Welcome users who register accounts
}

-- These modules are auto-loaded, but should you want
-- to disable them then uncomment them here:
modules_disabled = {
	-- "offline"; -- Store offline messages
	-- "c2s"; -- Handle client connections
	-- "s2s"; -- Handle server-to-server connections
	-- "posix"; -- POSIX functionality, sends server to background, etc.
}


-- Server-to-server authentication
-- Require valid certificates for server-to-server connections?
-- If false, other methods such as dialback (DNS) may be used instead.

s2s_secure_auth = true

-- Some servers have invalid or self-signed certificates. You can list
-- remote domains here that will not be required to authenticate using
-- certificates. They will be authenticated using other methods instead,
-- even when s2s_secure_auth is enabled.

--s2s_insecure_domains = { "insecure.example" }

-- Even if you disable s2s_secure_auth, you can still require valid
-- certificates for some domains by specifying a list here.

--s2s_secure_domains = { "jabber.org" }


-- Rate limits
-- Enable rate limits for incoming client and server connections. These help
-- protect from excessive resource consumption and denial-of-service attacks.

limits = {
	c2s = {
		rate = "10kb/s";
	};
	s2sin = {
		rate = "30kb/s";
	};
}

-- Required for init scripts and prosodyctl
pidfile = "/var/run/prosody/prosody.pid"

-- Authentication
-- Select the authentication backend to use. The 'internal' providers
-- use Prosody's configured data storage to store the authentication data.
-- For more information see https://prosody.im/doc/authentication

authentication = "internal_hashed"

-- Many authentication providers, including the default one, allow you to
-- create user accounts via Prosody's admin interfaces. For details, see the
-- documentation at https://prosody.im/doc/creating_accounts


-- Storage
-- Select the storage backend to use. By default Prosody uses flat files
-- in its configured data directory, but it also supports more backends
-- through modules. An "sql" backend is included by default, but requires
-- additional dependencies. See https://prosody.im/doc/storage for more info.

--storage = "sql" -- Default is "internal"

-- For the "sql" backend, you can uncomment *one* of the below to configure:
--sql = { driver = "SQLite3", database = "prosody.sqlite" } -- Default. 'database' is the filename.
--sql = { driver = "MySQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
--sql = { driver = "PostgreSQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }


-- Archiving configuration
-- If mod_mam is enabled, Prosody will store a copy of every message. This
-- is used to synchronize conversations between multiple clients, even if
-- they are offline. This setting controls how long Prosody will keep
-- messages in the archive before removing them.

archive_expires_after = "1w" -- Remove archived messages after 1 week

-- You can also configure messages to be stored in-memory only. For more
-- archiving options, see https://prosody.im/doc/modules/mod_mam


-- Audio/video call relay (STUN/TURN)
-- To ensure clients connected to the server can establish connections for
-- low-latency media streaming (such as audio and video calls), it is
-- recommended to run a STUN/TURN server for clients to use. If you do this,
-- specify the details here so clients can discover it.
-- Find more information at https://prosody.im/doc/turn

-- Specify the address of the TURN service (you may use the same domain as XMPP)
--turn_external_host = "turn.example.com"

-- This secret must be set to the same value in both Prosody and the TURN server
--turn_external_secret = "your-secret-turn-access-token"


-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
log = {
	info = "/var/log/prosody/prosody.log"; -- Change 'info' to 'debug' for verbose logging
	error = "/var/log/prosody/prosody.err";
	-- "*syslog"; -- Uncomment this for logging to syslog
	-- "*console"; -- Log to the console, useful for debugging when running in the foreground
}


-- Uncomment to enable statistics
-- For more info see https://prosody.im/doc/statistics
-- statistics = "internal"


-- Certificates
-- Every virtual host and component needs a certificate so that clients and
-- servers can securely verify its identity. Prosody will automatically load
-- certificates/keys from the directory specified here.
-- For more information, including how to use 'prosodyctl' to auto-import certificates
-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates

-- Location of directory to find certificates in (relative to main config file):
certificates = "certs"

Include "conf.d/*.cfg.lua"

---------- End of the Prosody Configuration file ----------
-- You usually **DO NOT** want to add settings here at the end, as they would
-- only apply to the last defined VirtualHost or Component.
--
-- Settings for the global section should go higher up, before the first
-- VirtualHost or Component line, while settings intended for specific hosts
-- should go under the corresponding VirtualHost or Component line.
--
-- For more information see https://prosody.im/doc/configure
