cfengine is a language based system specifically designed for testing
and configuring unix-like systems attached to a TCP/IP network.
cfrun is a tool for executing one or more remote agents; it contacts
the cfservd daemon running on a remote host, which (in turn) starts an
authorized agent. Cfrun cannot be used to send instructions to a remote
agent, but it can be used to flag certain aspects to the agent's exist‐
ing policy for special attention..
The command line options for cfrun are slightly unusual. They are sepa‐
rated into three sections: options to the cfrun program, options to the
remote cfagent (with some security restrictions) and finally classes or
flags to the remote agent.
EXAMPLEScfrun specialhost1 specialhost2 -- --verbose -- solaris
In this example, we contact hosts specialhost1 specialhost2 by name,
and ask them to execute cfagent with the --verbose flag, if the class
solaris is not defined.
cfrun specialhost1 --verbose---- solaris
In this example the verbose flag is sent to cfrun rather than to the
remote agent. No options are sent to the remote agents. The class
specifier is sent to all the agents so that they may determine whether
they fulfill the required class membership for execution.
The default behaviour is to execute cfagent serially on all hosts
listed in the cfrun.hosts file.
FILEScfrun read a configuration file cfrun.hosts which must contain a list
of every potentially contactable host.
