Kea scripts
I've started to use the Kea DHCP server on my little home network for IPv4 and IPv6 address delegation. To assist in the operation, I've written two simple scripts to show the leases assigned, one for IPv4 leases and the other for IPv6 leases.
The scripts work only with the memfile lease format.
These scripts can be thought of as a "sketch" that you may want to build upon, or "ideas" that you might want to use in your own scripts. The scripts function on my systems as noted below.
These Kea scripts are released to the Public Domain.
The scripts run under /bin/sh.
Sample output:
