dhcp_server's Issues

Installing dhcpd config fails on Ubuntu 14.04

Hi!

I am using your role successfully on several Debian images. Now I wanted to start testing on Ubuntu 14.04, but unfortunately the validation of the generated dhcpd config fails with

variable dhcp_ddns_unknown_clients = false breaks DHCP

Hello,

dhcp_common_ddns_unknown_clients introduced in f8d7e10 (and renamed to dhcp_ddns_unknown_clients in 253f7f8) is not working as one might guess from ddns in the variable name.

When the option dhcp_ddns_unknown_clients is not present, it in the end adds directive ignore unknown-clients; into dhcpd.conf.

This has nothing to do with DDNS and simply refuses to give leases to clients without a host declaration in dhcpd.conf.

I believe that this is a mistake and that the option should be removed or replaced (but I do not know what would be the replacement).
