21.7.2_1: DHCPv4 - do not send out NTP-servers (option 42)

(1/2) > >>

Udo:
Hello,

I've configured "Services -> DHCPv4 -> [Interface] -> NTP servers" with one IP.

A packet analysis with Wireshark shows that OPNsense DHCPv4 do not send out this NTP-server, option 42 is missing in DHCP-packet. Why is that?

Udo

MartB:
I can confirm, i dont see any option 42 being set in the offer.
I dont know if it ever worked tho!


--- Code: ---grep "ntp" /var/dhcpd/etc/dhcpd.conf
  option ntp-servers 10.0.1.1;

--- End code ---

larsd:
is your client requesting option 42?

franco:
That's a good question. :)


Cheers,
Franco

MartB:
The option is not directly requested, but i wonder where the behavior difference to the new version of iscs dhcp implementation (https://www.isc.org/kea/) comes from.
Kea sends it to me all the time regardless of the discovery and it gets ACKed by the client at the end.
