GLOBAL

The GLOBAL section contains application global configuration data.

CFG_DIR

Specify the path to a directory that contain additional configuration files. If a relative path is specified, the path will be relative to the directory where the main configuration file is at. All files in the specified directory will be read as additional configuration. Filenames starting with a dot are ignored.

TIMESTAMP_FORMAT

This variable specifies the format of the timestamp that is written in front of each row in the log file. The format string is in the same format as specified in the strftime(3) manual page. The default is "%c" which is described as: "the preferred date and time representation for the current locale". The environment variables LC_TIME, LC_ALL and LANG will affect how this time format will look. For example, setting LC_TIME="sv_SE.UTF8" will give you Swedish timestamp representation. Other examples of format specifiers are:

LISTEN_PORT

The TCP and UDP port number to use for network communications. The default is 5300. Make sure to open this port for incoming traffic to the server on both TCP and UDP. Clients do not have to open any ports in their firewalls.

SQL_TIMEOUT

Use this configuration variable to set a time in seconds after which a clients audio is blocked if he has been talking for too long. The default is 0 (disabled).

SQL_TIMEOUT_BLOCKTIME

If a client has been talking for longer than the time specified in the SQL_TIMEOUT configuration variable he will not be able to talk again until the time in this configuration variable have elapsed. If not specified, the default is one second.

CODECS

A comma separated list of allowed codecs. For the moment only one codec can be specified. Choose from the following codecs: OPUS, SPEEX, GSM, S16 (uncompressed signed 16 bit), RAW (uncompressed 32 bit floats). The default is OPUS and you should have a very good reason for changing this since that codec provide both low bandwidth (~20kbps by default) and very good audio quality.

TG_FOR_V1_CLIENTS

Set which talk group to place protocol version 1 clients in. Without this configuration version 1 clients will not be able to use the reflector since they cannot select a talk group by themselves. Talk groups should normally be configured to start with the ITU-T E.212 Mobile Country Code (MCC) for your country, e.g. 240 for Sweden.

RANDOM_QSY_RANGE

Specify in which talk group range the reflector server should select random talk groups used when using the QSY functionality. The range is specified using two colon separated values. The first one is the lower limit and the second value is the number of talk groups in the range. As an example, if set to 1239900:100 QSY talk groups will be selected from the range 1239900 to 1239999. The recommended lower range to use is <MCC>9900 where MCC is the ITU-T E.212 Mobile Country Code for your country, e.g. 240 for Sweden.

HTTP_SRV_PORT

Set which port to use for the HTTP server. The HTTP server can be used to fetch reflector status. No port is set by default. Don't expose this port to the public Internet. There are multiple reasons for that. The built in web server is very simple and could be incompatible with some clients. It has not been audited for security problems so there may be security issues. There is also the risk of some client overwhelming the reflector with requests causing disturbances in the reflector operation.

Example: HTTP_SRV_PORT=8080

USERS and PASSWORDS sections

All users must be specified in the USERS section. Usernames are totally arbitrary but typically the callsign is used. The purpose is to map each username to a password. However, the password is not given directly but instead a reference to the PASSWORDS section is given. It's done like this so that multiple nodes can share a single password.

An example of how the USERS and PASSWORDS sections may look is given below.

[USERS]
SM0ABC-1=MyNodes
SM0ABC-2=MyNodes
SM1XYZ=SM1XYZ

[PASSWORDS]
MyNodes="A very strong password!"
SM1XYZ="Another very good password?"

This will set up SM0ABC-1 and SM0ABC-2 to use the same password specified by MyNodes in the PASSWORDS section. User SM1XYZ have his own password.

Talkgroup Configuration Sections

It is possible to set configuration parameters that are only applied to one talkgroup. Those parameters are placed in a configuration section named "TG#<talkgroup id>". Example:

[TG#9999]
AUTO_QSY_AFTER=300
ALLOW=S[A-M]\\d.*|LA8PV
SHOW_ACTIVITY=0

The following configuration variables are valid in a talkgroup configuration section.

AUTO_QSY_AFTER

Set this to the number of seconds after which an automatic QSY to a random talkgroup is requested. This is typically used to keep call channels and wide area channels clear so that stations does not dwell there for too long. Auto QSY is only triggered directly aftar a talker stop event. The default is that auto QSY is disabled (AUTO_QSY_AFTER=0).

ALLOW

A regular expression that must match the whole callsign of the nodes that try to select this talkgroup. The regular expression standard used is the same as for ECMAScript with the exception that the backslash special patterns (e.g. \s, \d etc) must be expressed with double backslash notation (e.g. \\s, \\d etc).

An example that match most Swedish callsigns and a specific Norwegian one is "S[A-M]\\d.*|LA8PV". That expression will for example match LA8PV, SM0SVX, SK3W, SA7ABC etc.

SHOW_ACTIVITY

If set to 0, do not indicate in the http status message when the talkgroup is in use by a node. Default is 1 = show activity.
