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.


Print the help message
Specify how detailed logs should be. Possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug'
Enable debugging output
Output verbose information about the behaviour of the agent
Output the version of the software
Specify an alternative input file than the default. This option is overridden by FILE if supplied as argument.
Define a list of comma separated classes to be defined at the start of execution
Define a list of comma separated classes to be undefined at the start of execution
Ignore locking constraints during execution (ifelapsed/expireafter) if "too soon" to run
Print basic information about changes made to the system, i.e. promises repaired
Activate internal diagnostics (developers only)
Run as a foreground processes (do not fork)
Set the internal value of LD_LIBRARY_PATH for child processes
Generates avahi configuration file to enable policy server to be discovered in the network
Enable colorized output. Possible values: 'always', 'auto', 'never'. If option is used, the default value is 'auto'
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


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.
