cfrun: Execute remote cfagents

NAME

cfrun - Execute remote cfagents

SYNOPSIS

/usr/local/sbin/cfrun [options]

DESCRIPTION

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 existing policy for special attention..

The command line options for cfrun are slightly unusual. They are separated 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.

EXAMPLES

cfrun 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.

FILES

cfrun read a configuration file cfrun.hosts which must contain a list of every potentially contactable host.
