mumble-server.ini

; Mumble server configuration file.
;
; General notes:
; * Settings in this file are default settings and many of them can be overridden
;   with virtual server specific configuration via the Ice or DBus interface.
; * Due to the way this configuration file is read some rules have to be
;   followed when specifying variable values (as in variable = value):
;     * Make sure to quote the value when using commas in strings or passwords.
;        NOT variable = super,secret BUT variable = "super,secret"
;     * Make sure to escape special characters like '\' or '"' correctly
;        NOT variable = """ BUT variable = "\""
;        NOT regex = \w* BUT regex = \\w*
; * Any property that may be different on a per-user basis will require the
;   user to be registered to apply.

; When using SQLite: Path to database. If blank, will search for
;   mumble-server.sqlite in default locations or create it if not found.
; Otherwise: The name of the database to use for the Mumble server.
database=

; Selects the database to use. Possible values are
; - sqlite (default)
; - mysql
; - postgresql
;dbDriver=postgresql

;dbUsername=
;dbPassword=
;dbHost=
;dbPort=

; The server defaults to using SQLite with its default rollback journal.
; In some situations, using SQLite's write-ahead log (WAL) can be
; advantageous.
; If you encounter slowdowns when moving between channels and similar
; operations, enabling the SQLite write-ahead log might help.
;
; To use SQLite's write-ahead log, set sqlite_wal to one of the following
; values:
;
; 0 - Use SQLite's default rollback journal.
; 1 - No longer supported!
; 2 - Use write-ahead log with synchronous=FULL.
;     All database writes are synchronized to disk when they are made.
;     If the server crashes, the database will be include all completed writes.
;sqlite_wal=0

; If you want to use ZeroC Ice to communicate with the server, you need
; to specify the endpoint to use. Since there is no authentication
; with ICE, you should only use it if you trust all the users who have
; shell access to your machine.
; Please see the ICE documentation on how to specify endpoints.
ice="tcp -h 127.0.0.1 -p 6502"

; Ice primarily uses local sockets. This means anyone who has a
; user account on your machine can connect to the Ice services.
; You can set a plaintext "secret" on the Ice connection, and
; any script attempting to access must then have this secret
; (as context with name "secret").
; Access is split in read (look only) and write (modify)
; operations. Write access always includes read access,
; unless read is explicitly denied (see note below).
;
; Note that if this is uncommented and with empty content,
; access will be denied.

;icesecretread=
icesecretwrite=

; Specifies the file the server should log to.
; The default is 'mumble-server.log'. Set to an empty string to disable logging.
;logfile=mumble-server.log

; Specifies the identifier used by the server when logging to the system.
; The default is 'mumble-server'. Set to an empty string to disable logging.
; The system is syslog/journald on UNIX and the event registry on Windows.
;logsys=mumble-server

; If set, the server will write its process ID to this file
; when running in daemon mode (when the --foreground flag is not
; specified on the command line). Only available on
; Unix-like systems.
;pidfile=

; The below will be used as defaults for new configured servers.
; If you're just running one server (the default), it's easier to
; configure it here than through D-Bus or Ice.
;
; Welcome message sent to clients when they connect.
; If the welcome message is set to an empty string,
; no welcome message will be sent to clients.
welcometext="<br />Welcome to this server running <b>Mumble</b>.<br />Enjoy your stay!<br />"

; The welcometext can also be read from an external file which might be useful
; if you want to specify a rather lengthy text. If a value for welcometext is
; set, the welcometextfile will not be read.
;welcometextfile=

; Port to bind TCP and UDP sockets to.
port=64738

; Specific IP or hostname to bind to.
; If this is left blank (default), the server will bind to all available addresses.
;host=

; Password to join server.
serverpassword=

; Maximum bandwidth (in bits per second) clients are allowed
; to send speech at.
bandwidth=558000

; The Mumble client and server are usually pretty good about cleaning up hung clients,
; but occasionally one will get stuck on the server. The timeout setting will cause
; a periodic check of all clients who haven't communicated with the server in
; this many seconds - causing zombie clients to be disconnected.
;
; Note that this has no effect on idle clients or people who are AFK. It will
; only affect people who are already disconnected, and just haven't told the
; server.
;timeout=30

; A freshly accepted connection does not yet count as a client: it first has to
; complete the handshake and authenticate. The handshaketimeout setting drops
; connections that have been established this many seconds without authenticating,
; preventing them from accumulating (for example when a misbehaving or malicious
; peer opens connections but never authenticates). Set to 0 to disable.
;handshaketimeout=10

; Maximum number of concurrent clients allowed.
users=100

; Where users sets a blanket limit on the number of clients per virtual server,
; usersperchannel sets a limit on the number per channel. The default is 0, for
; no limit.
;usersperchannel=0

; Per-user rate limiting
;
; These two settings allow to configure the per-user rate limiter for some
; command messages sent from the client to the server. The messageburst setting
; specifies an amount of messages which are allowed in short bursts. The
; messagelimit setting specifies the number of messages per second allowed over
; a longer period. If a user hits the rate limit, his packages are then ignored
; for some time. Both of these settings have a minimum of 1 as setting either to
; 0 could render the server unusable.
messageburst=5
messagelimit=1

; Similar to messagelimit and messageburst, but these options apply specifically
; to "plugin-messages". That is messages that Mumble plugins send from client
; to client. The rate-limit collectively applies to all plugins active on a given
; client. That means if plugin A exhausts this limit and plugin B then attempts
; to send another message, the message from plugin B will be rate-limited.
; pluginmessagelimit=1
; pluginmessageburst=5

; Respond to UDP ping packets.
;
; Setting to true exposes the current user count, the maximum user count, and
; the server's maximum bandwidth per client to unauthenticated users. In the
; Mumble client, this information is shown in the Connect dialog.
allowping=true

; Amount of users with Opus support needed to force Opus usage, in percent.
; 0 = Always enable Opus, 100 = enable Opus if it's supported by all clients.
;opusthreshold=0

; Maximum depth of channel nesting. Note that some databases like MySQL using
; InnoDB will fail when operating on deeply nested channels.
;channelnestinglimit=10

; Maximum number of channels per server. 0 for unlimited. Note that an
; excessive number of channels will impact server performance
;channelcountlimit=1000

; Regular expression used to validate channel names.
; (Note that you have to escape backslashes with \ )
;channelname=[ \\-=\\w\\#\\[\\]\\{\\}\\(\\)\\@\\|]+

; Regular expression used to validate user names.
; (Note that you have to escape backslashes with \ )
;username=[-=\\w\\[\\]\\{\\}\\(\\)\\@\\|\\.]+

; If a user has no stored channel (they've never been connected to the server
; before, or rememberchannel is set to false) and the client hasn't been given
; a URL that includes a channel path, the default behavior is that they will
; end up in the root channel.
;
; You can set this setting to a channel ID, and the user will automatically be
; moved into that channel instead. Note that this is the numeric ID of the
; channel, which can be a little tricky to get (you'll either need to use an
; RPC mechanism, watch the console of a debug client, or root around through
; the server database to get it).
;
;defaultchannel=0

; When a user connects to a server they've already been on, by default the
; server will remember the last channel they were in and move them to it
; automatically. Toggling this setting to false will disable that feature.
;
;rememberchannel=true

; How many seconds should the server remember the last channel of a user.
; Set to 0 (default) to remember forever. This option has no effect if
; rememberchannel is set to false.
;rememberchannelduration=0

; Maximum length of text messages in characters. 0 for no limit.
;textmessagelength=5000

; Maximum length of text messages in characters, with image data. 0 for no limit.
;imagemessagelength=1048576

; Allow clients to use HTML in messages, user comments and channel descriptions?
;allowhtml=true

; The server retains the per-server log entries in an internal database which
; allows it to be accessed over D-Bus/ICE.
; How many days should such entries be kept?
; Set to 0 to keep forever, or -1 to disable logging to the DB.
;logdays=31

; To enable public server registration, the serverpassword must be blank, and
; this must all be filled out.
; The password here is used to create a registry for the server name; subsequent
; updates will need the same password. Don't lose your password.
; The URL is your own website, and only set the registerHostname for static IP
; addresses.
; Location is typically the country of typical users of the server, in
; two-letter TLD style (ISO 3166-1 alpha-2 country code)
;
; If you only wish to give your "Root" channel a custom name, then only
; uncomment the 'registerName' parameter.

;registerHostname=
;registerLocation=

; If this option is enabled, the server will announce its presence via the
; bonjour service discovery protocol. To change the name announced by bonjour
; adjust the registerName variable.
; See http://developer.apple.com/networking/bonjour/index.html for more information
; about bonjour.
;bonjour=true

; If you have a proper SSL certificate, you can provide the filenames here.
; Otherwise, the server will create its own certificate automatically.
;sslCert=
;sslKey=

; If the keyfile specified above is encrypted with a passphrase, you can enter
; it in this setting. It must be plaintext, so you may wish to adjust the
; permissions on your mumble-server.ini file accordingly.
;sslPassPhrase=

; If your certificate is signed by an authority that uses a sub-signed or
; "intermediate" certificate, you probably need to bundle it with your
; certificate in order to get the server to accept it. You can either concatenate
; the two certificates into one file, or you can put it in a file by itself and
; put the path to that PEM-file in sslCA.
;sslCA=

; The sslDHParams option allows you to specify a PEM-encoded file with
; Diffie-Hellman parameters, which will be used as the default Diffie-
; Hellman parameters for all virtual servers.
;
; Instead of pointing sslDHParams to a file, you can also use the option
; to specify a named set of Diffie-Hellman parameters for the server to use.
; The server comes bundled with the Diffie-Hellman parameters from RFC 7919.
; These parameters are available by using the following names:
;
; @ffdhe2048, @ffdhe3072, @ffdhe4096, @ffdhe6144, @ffdhe8192
;
; By default, the server uses @ffdhe2048.
;sslDHParams=@ffdhe2048

; The sslCiphers option chooses the cipher suites to make available for use
; in SSL/TLS. This option is server-wide, and cannot be set on a
; per-virtual-server basis.
;
; For TLS 1.2 and older, this option is specified using OpenSSL cipher list
; notation (see https://www.openssl.org/docs/apps/ciphers.html#CIPHER-LIST-FORMAT).
; TLS 1.3 cipher suites can be specified by name in the same colon-separated
; list, for instance TLS_AES_256_GCM_SHA384 or TLS_CHACHA20_POLY1305_SHA256.
;
; It is recommended that you try the TLS 1.2 and older part of your cipher
; string using 'openssl ciphers <string>' before setting it here, to get a feel
; for which cipher suites you will get.
;
; After setting this option, it is recommend that you inspect your server log
; to ensure that the server is using the cipher suites that you expected it to.
;
; Note: Changing this option may impact the backwards compatibility of your
; server, and can remove the ability for older Mumble clients to be able
; to connect to it.
;sslCiphers=EECDH+AESGCM:EDH+aRSA+AESGCM:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:AES256-SHA:AES128-SHA

; If the server is started as root, which user should it switch to?
; This option is ignored if the server isn't started with root privileges.
;uname=

; By default, in log files and in the user status window for privileged users,
; Mumble will show IP addresses - in some situations you may find this unwanted
; behavior. If obfuscate is set to true, the server will randomize the IP addresses
; of connecting users.
;
; The obfuscate function only affects the log file and DOES NOT effect the user
; information section in the client window.
;obfuscate=false

; If this options is enabled, only clients which have a certificate are allowed
; to connect.
;certrequired=false

; If enabled, clients are sent information about the servers version and operating
; system.
;sendversion=true

; You can set a recommended minimum version for your server, and clients will
; be notified in their log when they connect if their client does not meet the
; minimum requirements. suggestVersion expects the version in the format X.X.X.
;
; Note that the suggest* options appeared after 1.2.3 and will have no effect
; on client versions 1.2.3 and earlier.
;
;suggestVersion=

; Setting this to "true" will alert any user who does not have positional audio
; enabled that the server administrators recommend enabling it. Setting it to
; "false" will have the opposite effect - if you do not care whether the user
; enables positional audio or not, set it to blank. The message will appear in
; the log window upon connection, but only if the user's settings do not match
; what the server requests.
;
; Note that the suggest* options appeared after 1.2.3 and will have no effect
; on client versions 1.2.3 and earlier.
;
;suggestPositional=

; Setting this to "true" will alert any user who does not have Push-To-Talk
; enabled that the server administrators recommend enabling it. Setting it to
; "false" will have the opposite effect - if you do not care whether the user
; enables PTT or not, set it to blank. The message will appear in the log
; window upon connection, but only if the user's settings do not match what the
; server requests.
;
; Note that the suggest* options appeared after 1.2.3 and will have no effect
; on client versions 1.2.3 and earlier.

;suggestPushToTalk=

; This sets password hash storage to legacy mode (1.2.4 and before)
; (Note that setting this to true is insecure and should not be used unless absolutely necessary)
;legacypasswordhash=false

; By default a strong amount of PBKDF2 iterations are chosen automatically. If >0 this setting
; overrides the automatic benchmark and forces a specific number of iterations.
; (Note that you should only change this value if you know what you are doing)
;kdfiterations=-1

; In order to prevent misconfigured, impolite or malicious clients from
; affecting the low-latency of other users, the server has a rudimentary global-ban
; system. It's configured using the autobanAttempts, autobanTimeframe and
; autobanTime settings.
;
; If a client attempts autobanAttempts connections in autobanTimeframe seconds,
; they will be banned for autobanTime seconds. This is a global ban, from all
; virtual servers on the server process. It will not show up in any of the
; ban-lists on the server, and they can't be removed without restarting the
; server process - just let them expire. A single, properly functioning client
; should not trip these bans.
;
; To disable, set autobanAttempts or autobanTimeframe to 0. Commenting these
; settings out will cause the server to use the defaults:
;
; To avoid autobanning successful connection attempts from the same IP address,
; set autobanSuccessfulConnections=false.
;
;autobanAttempts=10
;autobanTimeframe=120
;autobanTime=300
;autobanSuccessfulConnections=true

; Enables logging of group changes. This means that every time a group in a
; channel changes, the server will log all groups and their members from before
; the change and after the change. Default is false. This option was introduced
; with Mumble server 1.4.0.
;
;loggroupchanges=false

; Enables logging of ACL changes. This means that every time the ACL in a
; channel changes, the server will log all ACLs from before the change and
; after the change. Default is false. This option was introduced with
; Mumble server 1.4.0.
;
;logaclchanges=false

; A flag dictating whether clients may use the built-in recording function. Newer
; clients will respect this option in the UI (e.g. disable the recording feature
; in the UI). Additionally any client that tries to start a recording is kicked
; from the server with a corresponding message, if recording is disabled.
; Default is true. This option was introduced with Mumble server 1.5.0.
;
; allowRecording=true

; The time frame in seconds the server will keep rolling packet stats for each client.
; The default is 5 minutes = 300 seconds. Minimum window is 10 seconds. Set to 0 to

;
; rollingStatsWindow=300

; The amount of allowed listener proxies in a single channel. It defaults to -1
; meaning that there is no limit. Set to 0 to disable Channel Listeners altogether.
; This option has been introduced with 1.4.0.
; listenersperchannel=5
