NAME¶
cf-serverd - CFEngine file server daemon
SYNOPSIS¶
cf-serverd [
OPTION]... [
FILE]
DESCRIPTION¶
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.
OPTIONS¶
- --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
- Specify an alternative input file than the default
- --define, -D
- Define a list of comma separated classes to be defined at the start of
execution
- --negate, -N
- 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
- 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
- --legacy-output, -l
- Use legacy output format
- --color, -C
- Enable colorized output. Possible values: 'always', 'auto', 'never'. If
option is used, the default value is 'auto'
CFENGINE¶
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/.
PROMISE THEORY¶
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.
