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.
