This Appendix contains a quick reference to the elements of the Connection Broker
configuration file, ssh-broker-config.xml.
The quick reference is divided
into four tables:
The tables list the available configuration file elements with their attributes, attribute values (with the default value, if available, marked in bold) and descriptions. The element names in the tables are links that take you to detailed descriptions of the elements in ssh-broker-config(5).
The element hierarchy is expressed with slashes ('/') between parent and child elements.
