cf-serverd - CFEngine file server daemon
cf-serverd [OPTION]... [FILE]
cf-serverd is a socket listening daemon providing two services: it acts as a file server for remote file copying and it allows an authorized cf-runagent to start a cf-agent run. cf-agent typically connects to a cf-serverd instance to request updated policy code, but may also request additional files for download. cf-serverd employs role based access control (defined in policy code) to authorize requests. Note: this daemon reloads it's config when the SIGHUP signal is received.
- --help, -h
- Print the help message
- --log-level, -g value
- Specify how detailed logs should be. Possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug'
- --debug, -d
- Enable debugging output
- --verbose, -v
- Output verbose information about the behaviour of the agent
- --version, -V
- Output the version of the software
- --file, -f value
- Specify an alternative input file than the default. This option is overridden by FILE if supplied as argument.
- --define, -D value
- Define a list of comma separated classes to be defined at the start of execution
- --negate, -N value
- Define a list of comma separated classes to be undefined at the start of execution
- --no-lock, -K
- Ignore locking constraints during execution (ifelapsed/expireafter) if "too soon" to run
- --inform, -I
- Print basic information about changes made to the system, i.e. promises repaired
- --diagnostic, -x
- Activate internal diagnostics (developers only)
- --no-fork, -F
- Run as a foreground processes (do not fork)
- --ld-library-path, -L value
- Set the internal value of LD_LIBRARY_PATH for child processes
- --generate-avahi-conf, -A
- Generates avahi configuration file to enable policy server to be discovered in the network
- --color, -C value
- Enable colorized output. Possible values: 'always', 'auto', 'never'. If option is used, the default value is 'auto'
- --timestamp, -l
- Log timestamps on each line of log output
CFEngine provides automated configuration management of
large-scale computer systems. A system administrator describes the desired
state of a system using CFEngine policy code. The program cf-agent
reads policy code and attempts to bring the current system state to the
desired state described. Policy code is downloaded by cf-agent from a
cf-serverd daemon. The daemon cf-execd is responsible for
running cf-agent periodically.
Documentation for CFEngine is available at http://cfengine.com/documentation/.
CFEngine is built on principles from promise theory, proposed by
Mark Burgess in 2004. Promise theory is a model of voluntary cooperation
between individual, autonomous actors or agents who publish their intentions
to one another in the form of promises. A promise is a declaration of intent
whose purpose is to increase the recipient's certainty about a claim of
past, present or future behaviour. For a promise to increase certainty, the
recipient needs to trust the promiser, but trust can also be built on the
verification that previous promises have been kept, thus trust plays a
symbiotic relationship with promises.
