CGRULESENGD(8) libcgroup Manual CGRULESENGD(8)

NAME

cgrulesengd - control group rules daemon
 

SYNOPSIS

cgrulesengd [options]
 

DESCRIPTION

cgrulesengd is a daemon, which distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group.
 
The list of rules is read during the daemon startup is are cached in the daemon's memory. The daemon reloads the list of rules when it receives SIGUSR2 signal. The daemon reloads the list of templates when it receives SIGUSR1 signal.
 
The daemon opens a standard unix socket to receive 'sticky' requests from cgexec.
 

OPTIONS

-h|--help
Display help.
-f <path>|--logfile=<path>
Write log messages to the given log file. When '-' is used as <path>, log messages are written to the standard output. If ' -f' and ' -s' are used together, the logs are sent to both destinations.
 
-s[facility]|--syslog=[facility]
Write log messages to syslog. The default facility is DAEMON. If ' -f' and ' -s' are used together, the logs are sent to both destinations.
-n|--nodaemon
Don't fork the daemon, stay in the foreground.
-v|--verbose
Display more log messages. This option can be used three times to enable more verbose log messages.
-q|--quiet
Display less log messages.
-Q|--nolog
Disable logging.
-d|--debug
Equivalent to '-nvvvf -', i.e. don't fork the daemon, display all log messages and write them to the standard output.
-u <user>|--socket-user=<user>
-g <group>|--socket-group=<group> Set the owner of cgrulesengd socket. Assumes that cgexec runs with proper suid permissions so it can write to the socket when cgexec --sticky is used.
