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 con‐ trol (defined in policy code) to authorize requests.


--help, -h Print the help message --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 --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 dae‐ mon. 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. For an introduction to promise theory, please see
