If your configuration file encompasses several different subnets with different conventions then you will need to use a more specific.

Using an enormous netgroup does not use up any space. BeginGroupIfNoMatch quoted-regex The lines following, up to the first EndGroup are executed if the quoted regular expression does not match the current line.

CFEngine Documentation – this

If silent is given, then cfengine will copy the files but not report the fact. Ctengine cfengine is started by root in a cron job and reads its cfengine. Thus, the parts of promises containing these features will be ignored. If the netmask variable is not set, cfengine ignores the default interface configuration. You can install the license with the cf-key -l command — you will need to copy over the licensed public key as advised by cf-key -l.


The defaultroute is also added to the static routing table. You can change the default values of these variables which are and 2 respectively in the control section. Inform editingUp: Peter can attest to this.

If cfengine is invoked with the option -athen it simply prints out this value. You should avoid hard links whenever possible. Function hostrangePrevious: Upgrading from CFEngine 2Previous: This is intended only for third party tools which collect and parse the cfengine output.

The context this is used to access information about promises during their execution. A hard link is in every way identical to the original file, it merely has a different name technically, it is a duplicate inode.

Note might actually be preferable to define classes returned by modules under AddInstallables which is equivalent. This is always a slightly dubious practice and is best avoided anyway. Note that these variables are not statically coded, but retrieved from the current system. Check that it exists and looks sensible. Note that single or double quotes may be used to enclose strings in cfengine. If a user does not possess the named file, cfengine just skips that user.

You can still use cfengine in this case but netgroups will not be expanded. Editing actions are always aborted as soon as the abort expression is matched.

This would be an enourmous overhead, so it is not done. BindToInterface in cfagentUp: Notes on windows policiesPrevious: It builds new directories.

Filters are defined in a separate section. It is used in conjunction with ReplaceLinesMatchingField. The modes ro and rw signify read-only and read-write respectively.

Example configuration fileUp: This action tests for the existence of a file or filesystem. Best practice for writing promisesUp: In recerence cases your netgroups will not correspond exactly to the list you want, but it might be more convenient to use a netgroup except for certain hosts.

If you use the same file for both purposes you risk losing warnings. The distinction is not predetermined.
