@cindex Murmur (VoIP server)
|
||||
@cindex VoIP server
|
||||
This section describes how to set up and run a Murmur server. Murmur is
|
||||
the server of the @uref{https://mumble.info, Mumble} voice-over-IP
|
||||
(VoIP) suite.
|
||||
|
||||
@deftp {Data Type} murmur-configuration
|
||||
The service type for the Murmur server. An example configuration can
|
||||
look like this:
|
||||
|
||||
@example
|
||||
(service murmur-service-type
|
||||
(murmur-configuration
|
||||
(welcome-text
|
||||
"Welcome to this Mumble server running on GuixSD!")
|
||||
(cert-required? #t) ;disallow text password logins
|
||||
(ssl-cert "/etc/letsencrypt/live/mumble.example.com/fullchain.pem")
|
||||
(ssl-key "/etc/letsencrypt/live/mumble.example.com/privkey.pem")))
|
||||
@end example
|
||||
|
||||
After reconfiguring your system, you can manually set the murmur @code{SuperUser}
|
||||
password with the command that is printed during the activation phase.
|
||||
|
||||
It is recommended to register a normal Mumble user account
|
||||
and grant it admin or moderator rights.
|
||||
You can use the @code{mumble} client to
|
||||
login as new normal user, register yourself, and log out.
|
||||
For the next step login with the name @code{SuperUser} use
|
||||
the @code{SuperUser} password that you set previously,
|
||||
and grant your newly registered mumble user administrator or moderator
|
||||
rights and create some channels.

||||

@item @code{cert-required?} (default: @code{#f})
|
||||

will not be accepted. Users must have completed the certificate wizard to join.
|
||||
|
||||
@item @code{remember-channel?} (defualt @code{#f})
|
||||
Should murmur remember the last channel each user was in when they disconnected

||||
@item @code{allow-html?} (default: @code{#f})
|
||||
Should html be allowed in text messages, user comments, and channel descriptions.
|
||||
|
||||
@item @code{allow-ping?} (default: @code{#f})
|
||||
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.
|
||||
|
||||
Disabling this setting will prevent public listing of the server.
|
||||
|
||||
@item @code{bonjour?} (default: @code{#f})
|
||||
Should the server advertise itself in the local network through the bonjour protocol.
|
||||

|
||||
Should the murmur server version be exposed in ping requests.
|
||||
|
||||
@item @code{log-days} (default: @code{31})
|
||||
Murmur also stores logs in the database, which are accessible via RPC.
|
||||
The default is 31 days of months, but you can set this setting to 0 to keep logs forever,
|
||||
or -1 to disable logging to the database.
|
||||
|
||||
@item @code{obfuscate-ips?} (default @code{#t})
|
||||
Should logged ips be obfuscated to protect the privacy of users.
|
||||
|
||||
@item @code{ssl-cert} (default: @code{#f})
|
||||
File name of the SSL/TLS certificate used for encrypted connections.
|
||||
|
||||

|
||||

|
||||
@end example
|
||||
@item @code{ssl-key} (default: @code{#f})
|
||||
Filepath to the ssl private key used for encrypted connections.
|
||||
@example
|
||||
(ssl-key "/etc/letsencrypt/live/example.com/privkey.pem")
|
||||
@end example
|
||||
|
||||
@item @code{ssl-dh-params} (default: @code{#f})
|
||||
File name of a PEM-encoded file with Diffie-Hellman parameters
|
||||
for the SSL/TLS encryption. Alternatively you set it to
|
||||
@code{"@@ffdhe2048"}, @code{"@@ffdhe3072"}, @code{"@@ffdhe4096"}, @code{"@@ffdhe6144"}
|
||||
or @code{"@@ffdhe8192"} to use bundled parameters from RFC 7919.
|
||||
|
||||
@item @code{ssl-ciphers} (default: @code{#f})
|
||||
The @code{ssl-ciphers} option chooses the cipher suites to make available for use
|
||||
in SSL/TLS.
|
||||
|
||||
This option is specified using
|
||||
@uref{https://www.openssl.org/docs/apps/ciphers.html#CIPHER-LIST-FORMAT,
|
||||
OpenSSL cipher list notation}.
|
||||
|
||||
It is recommended that you try 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 Murmur log
|
||||
to ensure that Murmur is using the cipher suites that you expected it to.
|
||||
|
||||
Note: Changing this option may impact the backwards compatibility of your
|
||||
Murmur server, and can remove the ability for older Mumble clients to be able
|
||||
to connect to it.
|
||||
|
||||
@item @code{public-registration} (default: @code{#f})
|
||||
Must be a @code{<murmur-public-registration-configuration>} record or @code{#f}.
|
||||
|
||||
You can optionally register your server in the public server list that the
|
||||
@code{mumble} client shows on startup.
|
||||
You cannot register your server if you have set a @code{server-password},
|
||||
or set @code{allow-ping} to @code{#f}.
|
||||
|
||||
It might take a few hours until it shows up in the public list.
|
||||
|
||||
@item @code{file} (default: @code{#f})
|
||||
Optional alternative override for this configuration.
|
||||
@end table
|
||||
@end deftp
|
||||
|
||||
@deftp {Data Type} murmur-public-registration-configuration
|
||||
Configuration for public registration of a murmur service.
|
||||
|
||||
@table @asis
|
||||
@item @code{name}
|
||||
This is a display name for your server. Not to be confused with the hostname.
|
||||
|
||||
@item @code{password}
|
||||
A password to identify your registration.
|
||||
Subsequent updates will need the same password. Don't lose your password.
|
||||
|
||||
@item @code{url}
|
||||
This should be a @code{http://} or @code{https://} link to your web
|
||||
site.
|
||||
|
||||
@item @code{hostname} (default: @code{#f})
|
||||
By default your server will be listed by its IP address.
|
||||
If it is set your server will be linked by this host name instead.
