Hi Olaf, I meant that you too generate the dnsmasq configuration files. I.e. a script or a generation command is involved. In your example, you maintained your information as a series of shell variable assignments (e.g. `dnsdomain=home.arpa`). Then you used the `tee` command to generate a

Hi Olaf, yeah I too settled for a sed command that transforms a dhcp-hosts file into an addn-hosts file. I maintain the main information in the dhcp-hosts file and then I run the sed command. Thank you, Alkis On 10/8/21 3:04 PM, Olaf Hering wrote: On Sun, Oct 03, Alkis Georgopoulos wrote:

Hi Alkis, I think you can use addn-hosts for name<=>IP address mapping and use dhcp-hostsfile just for mac address assignment to existing pair. But it prevents ability to create one file the other one, because primary data are split into two files. I guess creation of addn-hosts from dhcp-hosts

Thank you Petr, indeed I wouldn't mind at all to add a `,forever` in these dhcp-host lines if it automatically added them to DNS without having to boot them. Or to use a `dhcp-range=,some-flag` syntax. Fortunately a script that converts from dhcp-hosts to addn-hosts was rather easy to
