Kea Hooks

Kea allows extending DHCP operation by loading third party libraries that can extract information or even change how the server behaves. This mechanism is called hooks. This page lists currently available hook libraries.

While currently this list is modest, it is hoped to grow significantly in the near future. If you have developed your own hooks, feel free to announce them on kea-dev, kea-users and extend this page with appropriate entry.

Hook name License Author Link Description
user_chk MPL2.0 ISC User check is an example hook application that reads known users list from a file. If the user is not known, it will be assigned a lease from the last subnet defined in the configuration file, e.g. to redirect him into a captive portal. This showcases how externals source of information can be used to influence Kea allocation engine.
options_to_options ? Ola Thoresen This hook takes the value from different options in a DHCPREQUEST and inserts them into (other) options in a DHCPREPLY. Example usage is to take the value from an Option 82 string, and insert it in an Option 43 sub option, to direct the dhcp client to the correct config file in an auto provisioning scenario.
