remoteclassesmatching

This function is only available in CFEngine Enterprise.

Prototype: remoteclassesmatching(regex, server, encrypt, prefix)

Return type: class

Description: Read persistent classes matching regular expression regex from a remote CFEngine server server and add them into local context with prefix.

The return value is true (sets the class) if communication with the server was successful and classes were populated in the current bundle.

This function contacts a remote cf-serverd and requests access to defined persistent classes on that system. Access must be granted by making an access promise with resource_type set to context.

Arguments:

• regex : Regular expression, in the range .*

This should match a list of persistent classes of be returned from the server, if the server has granted access to them.

• server : Server name or address, in the range .*

The name or IP address of the remote server.

• encrypt : Boolean

Use encryption.

• prefix : Return class prefix, in the range [a-zA-Z0-9_$(){}\[\].:]+

A string to be added to the returned classes. If the server defines a persistent class alpha, then this would generate a private class in the current bundle called prefix_alpha.

Example:

   "succeeded" expression => remoteclassesmatching("regex","server","yes","myprefix");

Notes: Note that this function assumes that you have already performed a successful key exchange between systems, (e.g. using either a remote copy or cf-runagent connection). It contains no mechanism for trust establishment and will fail if there is no trust relationship pre-established.
