NAME

roard - RoarAudio sound server

 

SYNOPSIS

roard [OPTIONS]...

 

DESCRIPTION

roard is the most common RoarAudio sound server. The RoarAudio sound server is the central component in a RoarAudio setup. It mixes up diffrent audio streams from it's clients to send them to it's outputs. Such outputs include soundcards, monitoring clients, streaming servers and more.

 

GENERAL OPTIONS

NOTE: This list is incomplete!

--help
Print some help text.

--daemon
Go into background after startup.

--realtime
Ask for higher priority. May be used multiple times.

--memlock LEVEL
Sets default memory locking level to LEVEL.

Valid levels are:

none
No memory is locked at all.

low
Only very few (important) objects are locked in memory.

medium
Few (important) objects are locked in memory.

high
Many objects are locked in memory.

nearlyall
All known objects are locked in memory.

nearlyallsys
All known objects are locked in memory but also pages provided by the system like stack and heap.

allcur
All currently used pages are locked in memory.

all
All pages (including future allocated pages) are locked in memory.

default
Use defaults (the default).

A higher memlock level may result in memory allocations problems at runtime and even segfauls on some systems. (VM killed processes). Check your current system limits before altering this value.

--pidfile PIDFILE
Asks the server to use the given pidfile. This is recommended.

--sysclocksync
Messure exact audio clock frequency based on system time. obsolete.

 

SERVER INFO

--location LOC
Sets lion-readable location of server. Examples: livingroom, room 32

--description DESC
Sets lion-readable description of server. Examples: Stereo, UKW Transmitter

 

STARTUP AND SHUTDOWN

--start
Start a new server.

--stop
Stop the currently running server. See also --shutdown.

--restart
Stop the currently running server and start up a new server.

--shutdown
Terminates the currently running server after last client has quit. This is the most clean way to shutdown a running server as it does not kick any clients. This option must not be confused with --terminate.

--terminate
Auto terminates the new server after last client has quit. This option must not be confused with --shutdown.

--script-postdown S
Run script S after server shutdown. The script is passed to a shell. Any shell feature can be used within the string.

 

STANDBY MODE

--standby
Start in standby mode.

--auto-standby
Go into standby mode if no streams are active.

 

LOGGING

--verbose
Increment the verbosity level. Can be used multiple times.

--log-syslog
Log to syslog.

 

PLUGINS

--plugin-load
Load the given plugin.

 

SECURITY

--chroot DIR
Chroots to the given directory. This improves the security. This normally needs root privileg's.

 

USER AND GROUPS

--setgid
Sets GroupID to the audio group as specified via -G.

--setuid
Sets UserID to the audio user as specified via -U.

-G GROUP
Sets the group for the UNIX Domain Socket, (default: audio) You need the permittions to change the GID.

-U USER
Sets the user for the UNIX Domain Socket, (default: do not set) You need the permittions to change the UID (normaly only root has).

 

AUTH OPTIONS

The following options control the access rights of connections. Some of them take an access level. The access level is one from the following list:
none
This is used to disable an authentication method.

idented
Used internally. Should not be used.

conctl
The client is only allowed to do some basic operations only affecting it's own connection.

guest
Guest access (read only). The client may list resources but not alter them.

user
Normal user. The client may create and alter most resources.

pwruser
Power User. The client can create and alter all resources and do all operation but operations which would break the POSIX right system. The user is not allowed to control the server itself like terminating it or alter (system) resources with the rights of the user runnung roard.

This is the access level a fully trusted user in a multi user setup should have.

all
The client can do everything. This includes operations which may alter system resources (like files) with the rights of the user running roard.

This accesslevel should be given to the user in case of a single user setup or root or some administrator in a multi user setup.

--guest-acclev ACCESSLEVEL
Sets the access level for guest connections. Set to "none" to disable guest access.

--trust-acclev ACCESSLEVEL
Sets the access level for clients authenticated by trust auth. Set to "none" to disable trust auth.

--trust-root
Trust root user.

--no-trust-root
Do not trust root user.

--authfile-gen FILE
Generate a new authfile with a fresh cookie.

--authfile-load FILE
Load all keys from a given authfile.

--authfile-type TYPE
Sets the type for the authfile.

--authfile-acclev ACCLEV
Sets the access level for the given authfile.

--new-authfile
Add another authfile.
