The default location for the configuration file for the services is .Pa ~gnunet/.config/gnunet.conf Ns . However, as normal users also may need read-access to this configuration, you might want to instead put the service process configuration in .Pa @SYSCONFDIR@/gnunet.conf Ns . .Xr gnunet-setup 1 , part of gnunet-gtk, can be used to edit this configuration. The parts of GNUnet that are run as a normal user may have config options too and they read from .Pa $HOME/.config/gnunet.conf Ns . The latter config file can skip any options for the services. .Pp The basic structure of the configuration file is the following. .Bl -bullet -offset indent -compact .It The file is split into sections. .It Every section begins with a token in square brakets. The current section ends when a new section starts or end of file is encountered. .It A section contains a number of options of the form "OPTION=VALUE". .It Whitespace surrounding the "=" token is striped out, in other words "OPTION = VALUE" and "OPTION=VALUE" are treated equal. .It Empty lines and lines beginning with a "#" are treated as comments. .It Boolean values are given as "YES" and "NO". .El .Pp Almost all options are optional. The tools resort to reasonable defaults if an option is not present. Default values for all of the options can be found in the files in the .Pa $GNUNET_PREFIX/share/gnunet/config.d/ directory. A typical setup will work out of the box with those. See the examples section below for some common setups on top of that. .Ss Variable naming conventions and data types Boolean values for options are set via "YES" or "NO" values, without the double-quotes. .Pp Options which include "PATH" or "path" define a path on the file-system and can take additional variables in the path, such as .Ev $GNUNET_TMP . .Pp Section names as listed more in detail below, are small letters only enclosed by square brakets. .Ss GENERAL OPTIONS Many options will be common between sections. They can be repeated under each section with different values. The "[PATHS]" section is special. Here, it is possible to specify values for variables like "GNUNET_HOME". Then, in all filenames that begin with "$GNUNET_HOME" the "$GNUNET_HOME" will be replaced with the respective value at runtime. The main use of this is to redefine "$GNUNET_HOME", which by default points to .Pa $HOME/.config/ Ns . By setting this variable, you can change the location where GNUnet stores its internal data. .Pa gnunet.conf accepts the variable .Ev GNUNET_TMP which we suggest to use in place of the absolute definition of .Pa /tmp Ns . So instead of .Pa /tmp/foo you would write .Pa $GNUNET_TMP/foo . The usage of .Pa $GNUNET_TMP/foo , will result in .Pa $TMPDIR/gnunet/foo , or .Pa $TMP/gnunet/foo and finally, if .Ev TMPDIR is undefined, .Pa /tmp/gnunet/foo . The following options are generic and shared by all services: .Bl -tag -width indent .It HOSTNAME The hostname specifies the machine on which the service is running. This is usually "localhost". .It BINARY The filename that implements the service. For example "gnunet-service-ats". .It IMMEDIATE_START Start the service always when the peer starts. Set to YES for services that should always be launched, even if no other service explicitly needs them. .It START_ON_DEMAND Set to YES to automatically start the service when it is requested by another service. YES for most GNUnet services. .It NOARMBIND Set to YES to never have ARM bind to the respective socket. This option is mostly for debugging in situations where ARM cannot pass the pre-bound socket to the child due to interference from PREFIX-commands. This option is only effective in combination with IMMEDIATE_START being YES. NO by default. .It PREFIX PREFIX the given command (with its arguments) to the actual BINARY to be executed. Useful to run certain services under special supervisors like strace, dtrace, or valgrind. Typically used in combination with IMMEDIATE_START and NOARMBIND. Empty by default. .It ACCEPT_FROM A semi-column separated list of IPv4 addresses that are allowed to use the service; usually 127.0.0.1. .It ACCEPT_FROM6 A semi-column separated list of IPv6 addresses that are allowed to use the service; usually ::1. .It UNIXPATH Path to use for the UNIX domain socket for inter process communication with the service on POSIX systems. .It UNIX_MATCH_UID If UNIX domain sockets are used, set this to YES if only users with the same UID are allowed to access the service. .It UNIX_MATCH_GID If UNIX domain sockets are used, set this to YES if only users with the same GID are allowed to access the service. .It RUN_PER_USER End-users should never have to change the defaults GNUnet provides for this option. .Bl -tag -width indent .It YES Set to YES if this service should be run per-user. .It NO Set to NO if this is a system service. .El .El In the following sections the absence of a default value is either expressed as "Default value:" followed by nothing, or the lack of this line. .Ss ARM .Bl -tag -width indent .It PORT Default value: 2087 .It HOSTNAME Default value: localhost .It BINARY Default value: gnunet-service-arm .It ACCEPT_FROM Default value: 127.0.0.1; .It ACCEPT_FROM6 Default value: ::1; .It UNIXPATH Special case, uses user runtime dir even for per-system service. .Pp Default value: $GNUNET_USER_RUNTIME_DIR/gnunet-service-arm.sock .It UNIX_MATCH_UID Default value: YES .It UNIX_MATCH_GID Default value: YES .It GLOBAL_POSTFIX In the .Fl l option, format characters from .Xr strftime 3 are allowed; In the GLOBAL_POSTFIX, "{}" stands for the name of the respective service. Thus the following example for this option would introduce per-service logging with a new log file each day. Note that only the last 3 log files are preserved. Example: .Pp .Bd literal -l $GNUNET_CACHE_HOME/{}-%Y-%m-%d.log .Ed .Pp Default value: .It GLOBAL_PREFIX Default value: .It START_SYSTEM_SERVICES If set to YES, ARM will only start services that are marked as system-level services (and we'll expect a second ARM to be run per-user to run user-level services). Note that in this case you must have manually created a different configuration file with the user where at least this and the START_USER_SERVICES options differ. .It START_USER_SERVICES If set to YES, ARM will only start services that are marked as per-user services (and we'll expect a system user to run ARM to provide system-level services). Per-user services enable better personalization and privilege separation and in particular ensures that personal data is stored under $HOME, which might be important in a multi-user system (or if $HOME is encrypted and .Pa /var/ is not). .Pp Note that if you have different ARM services for SYSTEM and USER, and you are not on UNIX, you need to change the PORT option for the USER ARM instances to some free port (counting down from 2085 should provide free ports). .It RESOURCE_DIAGNOSTICS File where we should log per-service resource consumption on exit. .Pp Default value: resource.log .It USERNAME Name of the user that will be used to provide the service. .Pp Default value: .It MAXBUF Default value: .It TIMEOUT Default value: .It DISABLEV6 Default value: .It BINDTO Default value: .It REJECT_FROM Default value: .It REJECT_FROM6 Default value: .It PREFIX Default value: .El .Ss ATS .Bl -tag -width indent .It PORT Default value: 2098 .It HOSTNAME Default value: localhost .It BINARY Default value: gnunet-service-ats .It ACCEPT_FROM Default value: 127.0.0.1; .It ACCEPT_FROM6 Default value: ::1; .It UNIXPATH Default value: $GNUNET_RUNTIME_DIR/gnunet-service-ats.sock .It UNIX_MATCH_UID Default value: NO .It UNIX_MATCH_GID Default value: YES .It MODE Designated assignment mode.
