<h1 id="configuring-synapse"><a class="header" href="#configuring-synapse">Configuring Synapse</a></h1>
|
|
<p>This is intended as a guide to the Synapse configuration. The behavior of a Synapse instance can be modified
|
|
through the many configuration settings documented here — each config option is explained,
|
|
including what the default is, how to change the default and what sort of behaviour the setting governs.
|
|
Also included is an example configuration for each setting. If you don't want to spend a lot of time
|
|
thinking about options, the config as generated sets sensible defaults for all values. Do note however that the
|
|
database defaults to SQLite, which is not recommended for production usage. You can read more on this subject
|
|
<a href="../../setup/installation.html#using-postgresql">here</a>.</p>
|
|
<h2 id="config-conventions"><a class="header" href="#config-conventions">Config Conventions</a></h2>
|
|
<p>Configuration options that take a time period can be set using a number
|
|
followed by a letter. Letters have the following meanings:</p>
|
|
<ul>
|
|
<li><code>s</code> = second</li>
|
|
<li><code>m</code> = minute</li>
|
|
<li><code>h</code> = hour</li>
|
|
<li><code>d</code> = day</li>
|
|
<li><code>w</code> = week</li>
|
|
<li><code>y</code> = year</li>
|
|
</ul>
|
|
<p>For example, setting <code>redaction_retention_period: 5m</code> would remove redacted
|
|
messages from the database after 5 minutes, rather than 5 months.</p>
|
|
<p>In addition, configuration options referring to size use the following suffixes:</p>
|
|
<ul>
|
|
<li><code>M</code> = MiB, or 1,048,576 bytes</li>
|
|
<li><code>K</code> = KiB, or 1024 bytes</li>
|
|
</ul>
|
|
<p>For example, setting <code>max_avatar_size: 10M</code> means that Synapse will not accept files larger than 10,485,760 bytes
|
|
for a user avatar.</p>
|
|
<h3 id="yaml"><a class="header" href="#yaml">YAML</a></h3>
|
|
<p>The configuration file is a <a href="https://yaml.org/">YAML</a> file, which means that certain syntax rules
|
|
apply if you want your config file to be read properly. A few helpful things to know:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>#</code> before any option in the config will comment out that setting and either a default (if available) will
|
|
be applied or Synapse will ignore the setting. Thus, in example #1 below, the setting will be read and
|
|
applied, but in example #2 the setting will not be read and a default will be applied.</p>
|
|
<p>Example #1:</p>
|
|
<pre><code class="language-yaml">pid_file: DATADIR/homeserver.pid
|
|
</code></pre>
|
|
<p>Example #2:</p>
|
|
<pre><code class="language-yaml">#pid_file: DATADIR/homeserver.pid
|
|
</code></pre>
|
|
</li>
|
|
<li>
|
|
<p>Indentation matters! The indentation before a setting
|
|
will determine whether a given setting is read as part of another
|
|
setting, or considered on its own. Thus, in example #1, the <code>enabled</code> setting
|
|
is read as a sub-option of the <code>presence</code> setting, and will be properly applied.</p>
|
|
<p>However, the lack of indentation before the <code>enabled</code> setting in example #2 means
|
|
that when reading the config, Synapse will consider both <code>presence</code> and <code>enabled</code> as
|
|
different settings. In this case, <code>presence</code> has no value, and thus a default applied, and <code>enabled</code>
|
|
is an option that Synapse doesn't recognize and thus ignores.</p>
|
|
<p>Example #1:</p>
|
|
<pre><code class="language-yaml">presence:
|
|
enabled: false
|
|
</code></pre>
|
|
<p>Example #2:</p>
|
|
<pre><code class="language-yaml">presence:
|
|
enabled: false
|
|
</code></pre>
|
|
<p>In this manual, all top-level settings (ones with no indentation) are identified
|
|
at the beginning of their section (i.e. "### <code>example_setting</code>") and
|
|
the sub-options, if any, are identified and listed in the body of the section.
|
|
In addition, each setting has an example of its usage, with the proper indentation
|
|
shown.</p>
|
|
</li>
|
|
</ul>

|
<h2 id="modules"><a class="header" href="#modules">Modules</a></h2>
|
|
<p>Server admins can expand Synapse's functionality with external modules.</p>
|
|
<p>See <a href="../../modules/index.html">here</a> for more
|
|
documentation on how to configure or create custom modules for Synapse.</p>
|
|
<hr />
|
|
<h3 id="modules-1"><a class="header" href="#modules-1"><code>modules</code></a></h3>
|
|
<p>Use the <code>module</code> sub-option to add modules under this option to extend functionality.
|
|
The <code>module</code> setting then has a sub-option, <code>config</code>, which can be used to define some configuration
|
|
for the <code>module</code>.</p>
|
|
<p>Defaults to none.</p>
|
|
<p>Example configuration:</p>
|
|
<pre><code class="language-yaml">modules:
|
|
- module: my_super_module.MySuperClass
|
|
config:
|
|
do_thing: true
|
|
- module: my_other_super_module.SomeClass
|
|
config: {}
|
|
</code></pre>

<h2 id="server"><a class="header" href="#server">Server</a></h2>
|

<p>Define your homeserver name and other base options.</p>

<hr />

<h3 id="server_name"><a class="header" href="#server_name"><code>server_name</code></a></h3>

<p>This sets the public-facing domain of the server.</p>

<p>The <code>server_name</code> name will appear at the end of usernames and room addresses

created on your server. For example if the <code>server_name</code> was example.com,

usernames on your server would be in the format <code>@user:example.com</code></p>
|
|
<p>In most cases you should avoid using a matrix specific subdomain such as
|
|
matrix.example.com or synapse.example.com as the <code>server_name</code> for the same
|
|
reasons you wouldn't use user@email.example.com as your email address.

|
for information on how to host Synapse on a subdomain while preserving

|
a clean <code>server_name</code>.</p>
|
|
<p>The <code>server_name</code> cannot be changed later so it is important to
|
|
configure this correctly before you start Synapse. It should be all

lowercase and may contain an explicit port.</p>

<p>Forward extremities can build up in a room due to networking delays between
|
|
homeservers. Once this happens in a large room, calculation of the state of
|
|
that room can become quite expensive. To mitigate this, once the number of
|
|
forward extremities reaches a given threshold, Synapse will send an
|
|
<code>org.matrix.dummy_event</code> event, which will reduce the forward extremities
|
|
in the room.</p>
|
|
<p>This setting defines the threshold (i.e. number of forward extremities in the room) at which dummy events are sent.
|
|
The default value is 10.</p>

<p>Configuration for sending emails from Synapse.</p>
|
|
<p>Server admins can configure custom templates for email content. See
|
|
<a href="../../templates.html">here</a> for more information.</p>
|
|
<p>This setting has the following sub-options:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>smtp_host</code>: The hostname of the outgoing SMTP server to use. Defaults to 'localhost'.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>smtp_port</code>: The port on the mail server for outgoing SMTP. Defaults to 465 if <code>force_tls</code> is true, else 25.</p>
|
|
<p><em>Changed in Synapse 1.64.0:</em> the default port is now aware of <code>force_tls</code>.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>smtp_user</code> and <code>smtp_pass</code>: Username/password for authentication to the SMTP server. By default, no
|
|
authentication is attempted.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>force_tls</code>: By default, Synapse connects over plain text and then optionally upgrades
|
|
to TLS via STARTTLS. If this option is set to true, TLS is used from the start (Implicit TLS),
|
|
and the option <code>require_transport_security</code> is ignored.
|
|
It is recommended to enable this if supported by your mail server.</p>
|
|
<p><em>New in Synapse 1.64.0.</em></p>
|
|
</li>
|
|
<li>
|
|
<p><code>require_transport_security</code>: Set to true to require TLS transport security for SMTP.
|
|
By default, Synapse will connect over plain text, and will then switch to
|
|
TLS via STARTTLS <em>if the SMTP server supports it</em>. If this option is set,
|
|
Synapse will refuse to connect unless the server supports STARTTLS.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>enable_tls</code>: By default, if the server supports TLS, it will be used, and the server
|
|
must present a certificate that is valid for 'smtp_host'. If this option
|
|
is set to false, TLS will not be used.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>notif_from</code>: defines the "From" address to use when sending emails.
|
|
It must be set if email sending is enabled. The placeholder '%(app)s' will be replaced by the application name,
|
|
which is normally set in <code>app_name</code>, but may be overridden by the
|
|
Matrix client application. Note that the placeholder must be written '%(app)s', including the
|
|
trailing 's'.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>app_name</code>: <code>app_name</code> defines the default value for '%(app)s' in <code>notif_from</code> and email
|
|
subjects. It defaults to 'Matrix'.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>enable_notifs</code>: Set to true to enable sending emails for messages that the user
|
|
has missed. Disabled by default.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>notif_for_new_users</code>: Set to false to disable automatic subscription to email
|
|
notifications for new users. Enabled by default.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>client_base_url</code>: Custom URL for client links within the email notifications. By default
|
|
links will be based on "https://matrix.to". (This setting used to be called <code>riot_base_url</code>;
|
|
the old name is still supported for backwards-compatibility but is now deprecated.)</p>
|
|
</li>
|
|
<li>
|
|
<p><code>validation_token_lifetime</code>: Configures the time that a validation email will expire after sending.
|
|
Defaults to 1h.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>invite_client_location</code>: The web client location to direct users to during an invite. This is passed
|
|
to the identity server as the <code>org.matrix.web_client_location</code> key. Defaults
|
|
to unset, giving no guidance to the identity server.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>subjects</code>: Subjects to use when sending emails from Synapse. The placeholder '%(app)s' will
|
|
be replaced with the value of the <code>app_name</code> setting, or by a value dictated by the Matrix client application.
|
|
In addition, each subject can use the following placeholders: '%(person)s', which will be replaced by the displayname
|
|
of the user(s) that sent the message(s), e.g. "Alice and Bob", and '%(room)s', which will be replaced by the name of the room the
|
|
message(s) have been sent to, e.g. "My super room". In addition, emails related to account administration will
|
|
can use the '%(server_name)s' placeholder, which will be replaced by the value of the
|
|
<code>server_name</code> setting in your Synapse configuration.</p>
|
|
<p>Here is a list of subjects for notification emails that can be set:</p>
|
|
<ul>
|
|
<li><code>message_from_person_in_room</code>: Subject to use to notify about one message from one or more user(s) in a
|
|
room which has a name. Defaults to "[%(app)s] You have a message on %(app)s from %(person)s in the %(room)s room..."</li>

|
|
<p>This option disables/enables monthly active user blocking. Used in cases where the admin or
|
|
server owner wants to limit to the number of monthly active users. When enabled and a limit is
|
|
reached the server returns a <code>ResourceLimitError</code> with error type <code>Codes.RESOURCE_LIMIT_EXCEEDED</code>.
|
|
Defaults to false. If this is enabled, a value for <code>max_mau_value</code> must also be set.</p>

<p>The option <code>mau_trial_days</code> is a means to add a grace period for active users. It
|
|
means that users must be active for the specified number of days before they

<h3 id="retention"><a class="header" href="#retention"><code>retention</code></a></h3>
|
|
<p>This option and the associated options determine message retention policy at the
|
|
server level.</p>
|
|
<p>Room admins and mods can define a retention period for their rooms using the
|
|
<code>m.room.retention</code> state event, and server admins can cap this period by setting
|
|
the <code>allowed_lifetime_min</code> and <code>allowed_lifetime_max</code> config options.</p>
|
|
<p>If this feature is enabled, Synapse will regularly look for and purge events
|
|
which are older than the room's maximum retention period. Synapse will also
|
|
filter events received over federation so that events that should have been
|
|
purged are ignored and not stored again.</p>
|
|
<p>The message retention policies feature is disabled by default. Please be advised
|
|
that enabling this feature carries some risk. There are known bugs with the implementation
|
|
which can cause database corruption. Setting retention to delete older history
|
|
is less risky than deleting newer history but in general caution is advised when enabling this
|
|
experimental feature. You can read more about this feature <a href="../../message_retention_policies.html">here</a>.</p>
|
|
<p>This setting has the following sub-options:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>default_policy</code>: Default retention policy. If set, Synapse will apply it to rooms that lack the
|
|
'm.room.retention' state event. This option is further specified by the
|
|
<code>min_lifetime</code> and <code>max_lifetime</code> sub-options associated with it. Note that the
|
|
value of <code>min_lifetime</code> doesn't matter much because Synapse doesn't take it into account yet.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>allowed_lifetime_min</code> and <code>allowed_lifetime_max</code>: Retention policy limits. If
|
|
set, and the state of a room contains a <code>m.room.retention</code> event in its state
|
|
which contains a <code>min_lifetime</code> or a <code>max_lifetime</code> that's out of these bounds,
|
|
Synapse will cap the room's policy to these limits when running purge jobs.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>purge_jobs</code> and the associated <code>shortest_max_lifetime</code> and <code>longest_max_lifetime</code> sub-options:
|
|
Server admins can define the settings of the background jobs purging the
|
|
events whose lifetime has expired under the <code>purge_jobs</code> section.</p>
|
|
<p>If no configuration is provided for this option, a single job will be set up to delete
|
|
expired events in every room daily.</p>
|
|
<p>Each job's configuration defines which range of message lifetimes the job
|
|
takes care of. For example, if <code>shortest_max_lifetime</code> is '2d' and
|
|
<code>longest_max_lifetime</code> is '3d', the job will handle purging expired events in
|
|
rooms whose state defines a <code>max_lifetime</code> that's both higher than 2 days, and
|
|
lower than or equal to 3 days. Both the minimum and the maximum value of a
|
|
range are optional, e.g. a job with no <code>shortest_max_lifetime</code> and a
|
|
<code>longest_max_lifetime</code> of '3d' will handle every room with a retention policy
|
|
whose <code>max_lifetime</code> is lower than or equal to three days.</p>
|
|
<p>The rationale for this per-job configuration is that some rooms might have a
|
|
retention policy with a low <code>max_lifetime</code>, where history needs to be purged
|
|
of outdated messages on a more frequent basis than for the rest of the rooms
|
|
(e.g. every 12h), but not want that purge to be performed by a job that's
|
|
iterating over every room it knows, which could be heavy on the server.</p>
|
|
<p>If any purge job is configured, it is strongly recommended to have at least
|
|
a single job with neither <code>shortest_max_lifetime</code> nor <code>longest_max_lifetime</code>
|
|
set, or one job without <code>shortest_max_lifetime</code> and one job without
|
|
<code>longest_max_lifetime</code> set. Otherwise some rooms might be ignored, even if
|
|
<code>allowed_lifetime_min</code> and <code>allowed_lifetime_max</code> are set, because capping a
|
|
room's policy to these values is done after the policies are retrieved from
|
|
Synapse's database (which is done using the range specified in a purge job's
|
|
configuration).</p>

|
|
<p>A cache 'factor' is a multiplier that can be applied to each of
|
|
Synapse's caches in order to increase or decrease the maximum
|
|
number of entries that can be stored.</p>
|
|
<p><code>caches</code> can be configured through the following sub-options:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>global_factor</code>: Controls the global cache factor, which is the default cache factor
|
|
for all caches if a specific factor for that cache is not otherwise
|
|
set.</p>
|
|
<p>This can also be set by the <code>SYNAPSE_CACHE_FACTOR</code> environment
|
|
variable. Setting by environment variable takes priority over
|
|
setting through the config file.</p>
|
|
<p>Defaults to 0.5, which will halve the size of all caches.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>per_cache_factors</code>: A dictionary of cache name to cache factor for that individual
|
|
cache. Overrides the global cache factor for a given cache.</p>
|
|
<p>These can also be set through environment variables comprised
|
|
of <code>SYNAPSE_CACHE_FACTOR_</code> + the name of the cache in capital
|
|
letters and underscores. Setting by environment variable
|
|
takes priority over setting through the config file.
|
|
Ex. <code>SYNAPSE_CACHE_FACTOR_GET_USERS_WHO_SHARE_ROOM_WITH_USER=2.0</code></p>
|
|
<p>Some caches have '*' and other characters that are not
|
|
alphanumeric or underscores. These caches can be named with or
|
|
without the special characters stripped. For example, to specify
|
|
the cache factor for <code>*stateGroupCache*</code> via an environment
|
|
variable would be <code>SYNAPSE_CACHE_FACTOR_STATEGROUPCACHE=2.0</code>.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>expire_caches</code>: Controls whether cache entries are evicted after a specified time
|
|
period. Defaults to true. Set to false to disable this feature. Note that never expiring
|
|
caches may result in excessive memory usage.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>cache_entry_ttl</code>: If <code>expire_caches</code> is enabled, this flag controls how long an entry can
|
|
be in a cache without having been accessed before being evicted.
|
|
Defaults to 30m.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>sync_response_cache_duration</code>: Controls how long the results of a /sync request are
|
|
cached for after a successful response is returned. A higher duration can help clients
|
|
with intermittent connections, at the cost of higher memory usage.
|
|
A value of zero means that sync responses are not cached.
|
|
Defaults to 2m.</p>
|
|
<p><em>Changed in Synapse 1.62.0</em>: The default was changed from 0 to 2m.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>cache_autotuning</code> and its sub-options <code>max_cache_memory_usage</code>, <code>target_cache_memory_usage</code>, and
|
|
<code>min_cache_ttl</code> work in conjunction with each other to maintain a balance between cache memory
|
|
usage and cache entry availability. You must be using <a href="../administration/admin_faq.html#help-synapse-is-slow-and-eats-all-my-ramcpu">jemalloc</a>
|
|
to utilize this option, and all three of the options must be specified for this feature to work. This option
|

Please see the <a href="#config-conventions">Config Conventions</a> for information on how to specify memory size and cache expiry
|
|
durations.</p>
|
|
<ul>
|
|
<li><code>max_cache_memory_usage</code> sets a ceiling on how much memory the cache can use before caches begin to be continuously evicted.
|
|
They will continue to be evicted until the memory usage drops below the <code>target_memory_usage</code>, set in
|
|
the setting below, or until the <code>min_cache_ttl</code> is hit. There is no default value for this option.</li>
|
|
<li><code>target_cache_memory_usage</code> sets a rough target for the desired memory usage of the caches. There is no default value
|
|
for this option.</li>
|
|
<li><code>min_cache_ttl</code> sets a limit under which newer cache entries are not evicted and is only applied when
|
|
caches are actively being evicted/<code>max_cache_memory_usage</code> has been exceeded. This is to protect hot caches

<p><code>databases</code> is a dictionary of arbitrarily-named database entries. Each entry is equivalent
|
|
to the value of the <code>database</code> homeserver config option (see above), with the addition of
|
|
a <code>data_stores</code> key. <code>data_stores</code> is an array of strings that specifies the data store(s)
|
|
(a defined label for a set of tables) that should be stored on the associated database
|
|
backend entry.</p>
|
|
<p>The currently defined values for <code>data_stores</code> are:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>"state"</code>: Database that relates to state groups will be stored in this database.</p>
|
|
<p>Specifically, that means the following tables:</p>
|
|
<ul>
|
|
<li><code>state_groups</code></li>
|
|
<li><code>state_group_edges</code></li>
|
|
<li><code>state_groups_state</code></li>
|
|
</ul>
|
|
<p>And the following sequences:</p>
|
|
<ul>
|
|
<li><code>state_groups_seq_id</code></li>
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<p><code>"main"</code>: All other database tables and sequences.</p>
|
|
</li>
|
|
</ul>
|
|
<p>All databases will end up with additional tables used for tracking database schema migrations
|
|
and any pending background updates. Synapse will create these automatically on startup when checking for
|
|
and/or performing database schema migrations.</p>
|
|
<p>To migrate an existing database configuration (e.g. all tables on a single database) to a different
|
|
configuration (e.g. the "main" data store on one database, and "state" on another), do the following:</p>
|
|
<ol>
|
|
<li>
|
|
<p>Take a backup of your existing database. Things can and do go wrong and database corruption is no joke!</p>
|
|
</li>
|
|
<li>
|
|
<p>Ensure all pending database migrations have been applied and background updates have run. The simplest
|
|
way to do this is to use the <code>update_synapse_database</code> script supplied with your Synapse installation.</p>
|
|
<pre><code class="language-sh">update_synapse_database --database-config homeserver.yaml --run-background-updates
|
|
</code></pre>
|
|
</li>
|
|
<li>
|
|
<p>Copy over the necessary tables and sequences from one database to the other. Tables relating to database
|
|
migrations, schemas, schema versions and background updates should <strong>not</strong> be copied.</p>
|
|
<p>As an example, say that you'd like to split out the "state" data store from an existing database which
|
|
currently contains all data stores.</p>
|
|
<p>Simply copy the tables and sequences defined above for the "state" datastore from the existing database
|
|
to the secondary database. As noted above, additional tables will be created in the secondary database
|
|
when Synapse is started.</p>
|
|
</li>
|
|
<li>
|
|
<p>Modify/create the <code>databases</code> option in your <code>homeserver.yaml</code> to match the desired database configuration.</p>
|
|
</li>
|
|
<li>
|
|
<p>Start Synapse. Check that it starts up successfully and that things generally seem to be working.</p>
|
|
</li>
|
|
<li>
|
|
<p>Drop the old tables that were copied in step 3.</p>
|
|
</li>
|
|
</ol>
|
|
<p>Only one of the options <code>database</code> or <code>databases</code> may be specified in your config, but not both.</p>
|
|
<p>Example configuration:</p>
|
|
<pre><code class="language-yaml">databases:

<h3 id="rc_invites"><a class="header" href="#rc_invites"><code>rc_invites</code></a></h3>
|
|
<p>This option sets ratelimiting how often invites can be sent in a room or to a
|
|
specific user. <code>per_room</code> defaults to <code>per_second: 0.3</code>, <code>burst_count: 10</code> and
|
|
<code>per_user</code> defaults to <code>per_second: 0.003</code>, <code>burst_count: 5</code>.</p>
|
|
<p>Client requests that invite user(s) when <a href="https://spec.matrix.org/v1.2/client-server-api/#post_matrixclientv3createroom">creating a
|
|
room</a>
|
|
will count against the <code>rc_invites.per_room</code> limit, whereas

client requests to <a href="https://spec.matrix.org/v1.2/client-server-api/#post_matrixclientv3roomsroomidinvite">invite a single user to a
|
|
room</a>
|
|
will count against both the <code>rc_invites.per_user</code> and <code>rc_invites.per_room</code> limits.</p>
|
|
<p>Federation requests to invite a user will count against the <code>rc_invites.per_user</code>
|
|
limit only, as Synapse presumes ratelimiting by room will be done by the sending server.</p>
|
|
<p>The <code>rc_invites.per_user</code> limit applies to the <em>receiver</em> of the invite, rather than the
|
|
sender, meaning that a <code>rc_invite.per_user.burst_count</code> of 5 mandates that a single user
|
|
cannot <em>receive</em> more than a burst of 5 invites at a time.</p>
|
|
<p>In contrast, the <code>rc_invites.per_issuer</code> limit applies to the <em>issuer</em> of the invite, meaning that a <code>rc_invite.per_issuer.burst_count</code> of 5 mandates that single user cannot <em>send</em> more than a burst of 5 invites at a time.</p>
|

<p>This option sets a list of IP address CIDR ranges that the URL preview spider is allowed

|

This is useful for specifying exceptions to wide-ranging blacklisted

|

<p>Example configuration:</p>

|
|
<p>Optional list of URL matches that the URL preview spider is
|
|
denied from accessing. You should use <code>url_preview_ip_range_blacklist</code>
|
|
in preference to this, otherwise someone could define a public DNS
|
|
entry that points to a private IP address and circumvent the blacklist.
|
|
This is more useful if you know there is an entire shape of URL that
|
|
you know that will never want synapse to try to spider.</p>
|
|
<p>Each list entry is a dictionary of url component attributes as returned
|
|
by urlparse.urlsplit as applied to the absolute form of the URL. See
|
|
<a href="https://docs.python.org/2/library/urlparse.html#urlparse.urlsplit">here</a> for more

information. Some examples are:</p>

<li><code>netloc</code></li>
|
|
<li><code>scheme</code></li>
|
|
<li><code>path</code></li>
|
|
</ul>
|
|
<p>The values of the dictionary are treated as a filename match pattern
|
|
applied to that component of URLs, unless they start with a ^ in which
|
|
case they are treated as a regular expression match. If all the
|
|
specified component matches for a given list item succeed, the URL is
|

blacklisted.</p>

|
|
<p>By default, any room aliases included in this list will be created
|
|
as a publicly joinable room when the first user registers for the

homeserver. If the room already exists, make certain it is a publicly joinable
|
|
room, i.e. the join rule of the room must be set to 'public'. You can find more options

|
|
<p>The trusted servers to download signing keys from.</p>
|
|
<p>When we need to fetch a signing key, each server is tried in parallel.</p>
|
|
<p>Normally, the connection to the key server is validated via TLS certificates.
|
|
Additional security can be provided by configuring a <code>verify key</code>, which
|
|
will make synapse check that the response is signed by that key.</p>
|
|
<p>This setting supercedes an older setting named <code>perspectives</code>. The old format
|
|
is still supported for backwards-compatibility, but it is deprecated.</p>
|
|
<p><code>trusted_key_servers</code> defaults to matrix.org, but using it will generate a
|
|
warning on start-up. To suppress this warning, set
|
|
<code>suppress_key_server_warning</code> to true.</p>
|
|
<p>If the use of a trusted key server has to be deactivated, e.g. in a private
|
|
federation or for privacy reasons, this can be realised by setting
|
|
an empty array (<code>trusted_key_servers: []</code>). Then Synapse will request the keys
|
|
directly from the server that owns the keys. If Synapse does not get keys directly
|
|
from the server, the events of this server will be rejected.</p>
|
|
<p>Options for each entry in the list include:</p>
|
|
<ul>
|
|
<li><code>server_name</code>: the name of the server. Required.</li>
|
|
<li><code>verify_keys</code>: an optional map from key id to base64-encoded public key.
|
|
If specified, we will check that the response is signed by at least
|
|
one of the given keys.</li>
|
|
<li><code>accept_keys_insecurely</code>: a boolean. Normally, if <code>verify_keys</code> is unset,
|
|
and <code>federation_verify_certificates</code> is not <code>true</code>, synapse will refuse
|
|
to start, because this would allow anyone who can spoof DNS responses
|
|
to masquerade as the trusted key server. If you know what you are doing
|
|
and are sure that your network environment provides a secure connection
|
|
to the key server, you can set this to <code>true</code> to override this behaviour.</li>
|
|
</ul>
|
|
<p>Example configuration #1:</p>
|
|
<pre><code class="language-yaml">trusted_key_servers:
|
|
- server_name: "my_trusted_server.example.com"
|
|
verify_keys:

<p>The following settings can be used to make Synapse use a single sign-on

provider for authentication, instead of its internal password database.</p>
|

<p>You will probably also want to set the following options to <code>false</code> to

<h3 id="saml2_config"><a class="header" href="#saml2_config"><code>saml2_config</code></a></h3>
|
|
<p>Enable SAML2 for registration and login. Uses pysaml2. To learn more about pysaml and
|
|
to find a full list options for configuring pysaml, read the docs <a href="https://pysaml2.readthedocs.io/en/latest/">here</a>.</p>
|
|
<p>At least one of <code>sp_config</code> or <code>config_path</code> must be set in this section to
|
|
enable SAML login. You can either put your entire pysaml config inline using the <code>sp_config</code>
|
|
option, or you can specify a path to a psyaml config file with the sub-option <code>config_path</code>.
|
|
This setting has the following sub-options:</p>
|
|
<ul>
|
|
<li><code>sp_config</code>: the configuration for the pysaml2 Service Provider. See pysaml2 docs for format of config.
|
|
Default values will be used for the <code>entityid</code> and <code>service</code> settings,
|
|
so it is not normally necessary to specify them unless you need to
|
|
override them. Here are a few useful sub-options for configuring pysaml:
|
|
<ul>
|
|
<li><code>metadata</code>: Point this to the IdP's metadata. You must provide either a local
|
|
file via the <code>local</code> attribute or (preferably) a URL via the
|
|
<code>remote</code> attribute.</li>
|
|
<li><code>accepted_time_diff: 3</code>: Allowed clock difference in seconds between the homeserver and IdP.
|
|
Defaults to 0.</li>
|
|
<li><code>service</code>: By default, the user has to go to our login page first. If you'd like
|
|
to allow IdP-initiated login, set <code>allow_unsolicited</code> to true under <code>sp</code> in the <code>service</code>
|
|
section.</li>
|
|
</ul>
|
|
</li>
|
|
<li><code>config_path</code>: specify a separate pysaml2 configuration file thusly:
|
|
<code>config_path: "CONFDIR/sp_conf.py"</code></li>
|
|
<li><code>saml_session_lifetime</code>: The lifetime of a SAML session. This defines how long a user has to
|
|
complete the authentication process, if <code>allow_unsolicited</code> is unset. The default is 15 minutes.</li>
|
|
<li><code>user_mapping_provider</code>: Using this option, an external module can be provided as a
|
|
custom solution to mapping attributes returned from a saml provider onto a matrix user. The
|
|
<code>user_mapping_provider</code> has the following attributes:
|
|
<ul>
|
|
<li><code>module</code>: The custom module's class.</li>
|
|
<li><code>config</code>: Custom configuration values for the module. Use the values provided in the
|
|
example if you are using the built-in user_mapping_provider, or provide your own
|
|
config values for a custom class if you are using one. This section will be passed as a Python
|
|
dictionary to the module's <code>parse_config</code> method. The built-in provider takes the following two
|
|
options:
|
|
<ul>
|
|
<li><code>mxid_source_attribute</code>: The SAML attribute (after mapping via the attribute maps) to use
|
|
to derive the Matrix ID from. It is 'uid' by default. Note: This used to be configured by the
|
|
<code>saml2_config.mxid_source_attribute option</code>. If that is still defined, its value will be used instead.</li>
|
|
<li><code>mxid_mapping</code>: The mapping system to use for mapping the saml attribute onto a
|
|
matrix ID. Options include: <code>hexencode</code> (which maps unpermitted characters to '=xx')
|
|
and <code>dotreplace</code> (which replaces unpermitted characters with '.').
|
|
The default is <code>hexencode</code>. Note: This used to be configured by the
|
|
<code>saml2_config.mxid_mapping option</code>. If that is still defined, its value will be used instead.</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
<li><code>grandfathered_mxid_source_attribute</code>: In previous versions of synapse, the mapping from SAML attribute to
|
|
MXID was always calculated dynamically rather than stored in a table. For backwards- compatibility, we will look for <code>user_ids</code>
|
|
matching such a pattern before creating a new account. This setting controls the SAML attribute which will be used for this
|
|
backwards-compatibility lookup. Typically it should be 'uid', but if the attribute maps are changed, it may be necessary to change it.
|
|
The default is 'uid'.</li>
|
|
<li><code>attribute_requirements</code>: It is possible to configure Synapse to only allow logins if SAML attributes
|
|
match particular values. The requirements can be listed under
|
|
<code>attribute_requirements</code> as shown in the example. All of the listed attributes must
|
|
match for the login to be permitted.</li>
|
|
<li><code>idp_entityid</code>: If the metadata XML contains multiple IdP entities then the <code>idp_entityid</code>
|
|
option must be set to the entity to redirect users to.
|
|
Most deployments only have a single IdP entity and so should omit this option.</li>
|
|
</ul>
|
|
<p>Once SAML support is enabled, a metadata file will be exposed at
|
|
<code>https://<server>:<port>/_synapse/client/saml2/metadata.xml</code>, which you may be able to
|
|
use to configure your SAML IdP with. Alternatively, you can manually configure
|
|
the IdP to use an ACS location of
|
|
<code>https://<server>:<port>/_synapse/client/saml2/authn_response</code>.</p>
|
|
<p>Example configuration:</p>
|
|
<pre><code class="language-yaml">saml2_config:
|
|
sp_config:
|
|
metadata:
|
|
local: ["saml2/idp.xml"]

<p>List of OpenID Connect (OIDC) / OAuth 2.0 identity providers, for registration
|
|
and login. See <a href="../../openid.html">here</a>
|
|
for information on how to configure these options.</p>
|
|
<p>For backwards compatibility, it is also possible to configure a single OIDC
|
|
provider via an <code>oidc_config</code> setting. This is now deprecated and admins are
|
|
advised to migrate to the <code>oidc_providers</code> format. (When doing that migration,
|
|
use <code>oidc</code> for the <code>idp_id</code> to ensure that existing users continue to be
|
|
recognised.)</p>
|
|
<p>Options for each entry include:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>idp_id</code>: a unique identifier for this identity provider. Used internally
|
|
by Synapse; should be a single word such as 'github'.
|
|
Note that, if this is changed, users authenticating via that provider
|
|
will no longer be recognised as the same user!
|
|
(Use "oidc" here if you are migrating from an old <code>oidc_config</code> configuration.)</p>

|
|
by clients and Synapse's own IdP picker page. If given, must be an
|
|
MXC URI of the format mxc://<server-name>/<media-id>. (An easy way to
|
|
obtain such an MXC URI is to upload an image to an (unencrypted) room
|
|
and then copy the "url" from the source of the event.)</p>
|
|
</li>
|
|
<li>
|
|
<p><code>idp_brand</code>: An optional brand for this identity provider, allowing clients

<li>

<p><code>backchannel_logout_enabled</code>: set to <code>true</code> to process OIDC Back-Channel Logout notifications.
|
|
Those notifications are expected to be received on <code>/_synapse/client/oidc/backchannel_logout</code>.
|
|
Defaults to <code>false</code>.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>backchannel_logout_ignore_sub</code>: by default, the OIDC Back-Channel Logout feature checks that the
|
|
<code>sub</code> claim matches the subject claim received during login. This check can be disabled by setting
|
|
this to <code>true</code>. Defaults to <code>false</code>.</p>
|
|
<p>You might want to disable this if the <code>subject_claim</code> returned by the mapping provider is not <code>sub</code>.</p>
|
|
</li>
|
|
</ul>
|
|
<p>It is possible to configure Synapse to only allow logins if certain attributes

match particular values in the OIDC userinfo. The requirements can be listed under
|
|
<code>attribute_requirements</code> as shown here:</p>
|
|
<pre><code class="language-yaml">attribute_requirements:

- attribute: family_name

value: "Stephensson"
|
|
- attribute: groups

|
value: "admin"
|
|
</code></pre>
|
|
<p>All of the listed attributes must match for the login to be permitted. Additional attributes can be added to
|
|
userinfo by expanding the <code>scopes</code> section of the OIDC config to retrieve
|
|
additional information from the OIDC provider.</p>
|
|
<p>If the OIDC claim is a list, then the attribute must match any value in the list.
|
|
Otherwise, it must exactly match the value of the claim. Using the example
|
|
above, the <code>family_name</code> claim MUST be "Stephensson", but the <code>groups</code>
|
|
claim MUST contain "admin".</p>

<p>Options include:</p>
|
|
<ul>
|

|
whose URL starts with an entry in the following list will not be subject
|
|
to an additional confirmation step after the SSO login is completed.
|
|
WARNING: An entry such as "https://my.client" is insecure, because it
|
|
will also match "https://my.client.evil.site", exposing your users to
|
|
phishing attacks from evil.site. To avoid this, include a slash after the
|
|
hostname: "https://my.client/".
|
|
The login fallback page (used by clients that don't natively support the
|
|
required login flows) is whitelisted in addition to any URLs in this list.
|
|
By default, this list contains only the login fallback page.</li>
|
|
<li><code>update_profile_information</code>: Use this setting to keep a user's profile fields in sync with information from

|
the identity provider. Currently only syncing the displayname is supported. Fields
|
|
are checked on every SSO login, and are updated if necessary.
|
|
Note that enabling this option will override user profile information,

<hr />
|
|
<h3 id="push-1"><a class="header" href="#push-1"><code>push</code></a></h3>
|
|
<p>This setting defines options for push notifications.</p>
|
|
<p>This option has a number of sub-options. They are as follows:</p>
|
|
<ul>
|
|
<li><code>enabled</code>: Enables or disables push notification calculation. Note, disabling this will also
|
|
stop unread counts being calculated for rooms. This mode of operation is intended
|
|
for homeservers which may only have bots or appservice users connected, or are otherwise
|
|
not interested in push/unread counters. This is enabled by default.</li>
|
|
<li><code>include_content</code>: Clients requesting push notifications can either have the body of
|
|
the message sent in the notification poke along with other details
|
|
like the sender, or just the event ID and room ID (<code>event_id_only</code>).
|
|
If clients choose the to have the body sent, this option controls whether the
|
|
notification request includes the content of the event (other details
|
|
like the sender are still included). If <code>event_id_only</code> is enabled, it
|
|
has no effect.
|
|
For modern android devices the notification content will still appear
|
|
because it is loaded by the app. iPhone, however will send a
|
|
notification saying only that a message arrived and who it came from.
|
|
Defaults to true. Set to false to only include the event ID and room ID in push notification payloads.</li>
|
|
<li><code>group_unread_count_by_room: false</code>: When a push notification is received, an unread count is also sent.
|
|
This number can either be calculated as the number of unread messages for the user, or the number of <em>rooms</em> the
|
|
user has unread messages in. Defaults to true, meaning push clients will see the number of
|
|
rooms with unread messages in them. Set to false to instead send the number
|
|
of unread messages.</li>
|

Defaults to false.</p>
|
|
<p>NB. If you set this to true, and the last time the user_directory search

<p>Missing user_id/room_id/alias fields default to "*".</p>
|
|
<p>If no rules match the request is denied. An empty list means no one

|
|
<p>Options for the rules include:</p>
|

<ul>
|

<li><code>user_id</code>: Matches against the creator of the alias. Defaults to "*".</li>

|
|
<p>The <code>default_power_level_content_override</code> option controls the default power

levels for rooms.</p>
|
|
<p>Useful if you know that your users need special permissions in rooms
|
|
that they create (e.g. to send particular types of state events without
|
|
needing an elevated power level). This takes the same shape as the
|
|
<code>power_level_content_override</code> parameter in the /createRoom API, but
|
|
is applied before that parameter.</p>
|
|
<p>Note that each key provided inside a preset (for example <code>events</code> in the example
|
|
below) will overwrite all existing defaults inside that key. So in the example
|
|
below, newly-created private_chat rooms will have no rules for any event types
|
|
except <code>com.example.foo</code>.</p>

<p>Configuration options related to workers which belong in the main config file

|
|
A Synapse deployment can scale horizontally by running multiple Synapse processes
|
|
called <em>workers</em>. Incoming requests are distributed between workers to handle higher
|
|
loads. Some workers are privileged and can accept requests from other workers.</p>
|
|
<p>As a result, the worker configuration is divided into two parts.</p>
|
|
<ol>
|
|
<li>The first part (in this section of the manual) defines which shardable tasks
|
|
are delegated to privileged workers. This allows unprivileged workers to make
|
|
requests to a privileged worker to act on their behalf.</li>
|
|
<li><a href="#individual-worker-configuration">The second part</a>

|
|
<ul>
|
|
<li><code>background_update_duration_ms</code>: How long in milliseconds to run a batch of background updates for. Defaults to 100.
|
|
Set a different time to change the default.</li>
|
|
<li><code>sleep_enabled</code>: Whether to sleep between updates. Defaults to true. Set to false to change the default.</li>
|
|
<li><code>sleep_duration_ms</code>: If sleeping between updates, how long in milliseconds to sleep for. Defaults to 1000.
|
|
Set a duration to change the default.</li>
|
|
<li><code>min_batch_size</code>: Minimum size a batch of background updates can be. Must be greater than 0. Defaults to 1.
|
|
Set a size to change the default.</li>
|
|
<li><code>default_batch_size</code>: The batch size to use for the first iteration of a new background update. The default is 100.
|
|
Set a size to change the default.</li>
|
|
</ul>
|
|
<p>Example configuration:</p>
|
|
<pre><code class="language-yaml">background_updates:
|
|
background_update_duration_ms: 500
|
|
sleep_enabled: false
|
|
sleep_duration_ms: 300
|
|
