NAME
cfengine - network configuration engine
SYNOPSIS
/usr/gnu/sbin/cfengine [options]
DESCRIPTION
cfengine
is a language based system specifically designed
for testing and configuring unix-like systems attached to
a TCP/IP network. You can think of
cfengine
as a very high
level language -- much higher level than Perl or shell. A
single statement can result in many hundreds of links
being created, or the permissions of many hundreds of
files being set. The idea of
cfenginge
is to create a
single file or set of configuration files which will
describe the setup of every host on your network.
cfenginge
runs on every host and parses one file (or file-set),
the configuration of the host is checked against this file
and, if desired, any deviations are fixed.
cfenginge
reads a configuration file called cfengine.conf in
a directory pointed to by the environment variable CFINPUTS.
cfenginge
performs host integrity and security checks as well
as installing and repairing system configuration.
COMMAND LINE OPTIONS
- -a (--sysadm)
-
Print only the name of the system administrator then quit.
- -b (--force-net-copy)
-
Forces net copy even if remote server is localhost
- -c (--no-check-files)
-
Do not check access rights on file systems
- -C (--no-check-mounts)
-
Check mount points for consistency. If this option is set
then directories which lie in the ''mount point`` area are
checked to see whether there is anything mounted on them.
- -d (--debug)
-
Enable debugging output. (parsing -d1,run, -d2, lite -d3)
- -D (--define)
-
Define a compound class symbol of the form alpha.beta.gamma.
- -e (--no-edits)
-
Suppress file editing.
- -E (--enforce-links)
-
Globally force links to be created where plain files or
links already exist. You have to use this in
interactive mode and answer a yes/no query before
cfenginge
will run like this.
- -f (--file)
-
Parse filename after this switch. By default
cfenginge
looks for a file called cfengine.conf in the current directory.
- -h (--help )
-
Help information. Display version banner and options summary.
- -H (--no-hard-classes)
-
Prevents
cfenginge
from generating any internal class name
information. Can be used for emulation purposes.
- -i (--no-ifconfig)
-
Do not attempt to configure the local area network interface.
- -I (--inform)
-
Switches on the inform output level, whereby
cfenginge
reports everything it changes..
- -k (--no-copy)
-
Do not copy/image any files.
- -K (--no-lock)
-
Ignore locks when running.
- -l (--traverse-links)
-
Normally
cfenginge
does not follow symbolic links when recursively
parsing directories. This option will force it to do so.
- -L (--delete-stale-links)
-
Delete links which do not point to existing files (except in
user home directories, which are not touched).
- -m (--no-mount)
-
Do not attempt to mount file systems or edit the filesystem table.
- -M (--no-modules)
-
Ignore modules in actionsequence.
- -n (--recon,--dry-run,--just-print)
-
No action. Only print what has to be done without actually doing it.
- -N (--negate,--undefine)
-
Cancel a set of classes, or undefine (set value to false) a
compound class of the form alpha.beta.gamma.
- -p (--parse-only)
-
Parse file and then stop. Used for checking the syntax of a
program.
- -q (--no-splay)
-
Switch off host splaying (sleeping).
- -s (--no-commands)
-
Do not execute scripts or shell commands.
- -S (--silent)
-
Silence run time warnings.
- -t (--no-tidy)
-
Do not tidy file systems.
- -u (--use-env)
-
Causes
cfenginge
to generate an environment variable CFALLCLASSES
which can be read by child processes (scripts). This variable
contains a summary of all the currently defined classes at any
given time. This option causes some system 5 systems to generate
a Bus Error or segmentation fault.
- -U (--underscore-classes)
-
When this option is set,
cfenginge
adds an underscore to the
beginning of all hard system classes (like _sun4, _linux etc.)
This can be used to avoid naming conflicts if you are so injudicious
as to name a host by the name of a hard class. Other classes
are not affected.
- -v (--verbose)
-
Verbose mode. Prints detailed information about actions and state.
- -V (--version)
-
Print only the version string and then quit.
- -x (--no-preconf)
-
Do not execute the cf.preconf net configuration file.
- -X (--no-links)
-
Do not execute the links section of a program.
- -w (--no-warn,--quiet)
-
Do not print warning messages.
