I have Ubuntu 14.04.1 LTS with Webmin 1.700 and isc-dhcp-server 4.2.4-7ubuntu12.
The Webmin startup scripts seem disconnected with the system scripts and doesn't detect that the dhcpd process is running after a reboot. When I go to the DHCP Server management page in Webmin after a reboot, it says the server is stopped, yet the process is there.
If I tell Webmin to start the DHCP server, it will fire up another instance.
Am I missing something?
