I am capturing DHCP packets with tcpdump. The client sends a DHCP request asking for the DHCP configuration which contains a request for NTP servers but in the DHCP ACK message sent by the router there is no NTP server information. Shouldn't the server answer with the NTP server's IPs as it does with the domain name servers? What am I missing?
In case that the device is not getting NTP servers' addresses through DHCP because my home router does not support it, where can it get the NTP server that it is using from? It is not a manually configured parameter, is there any other service for getting NTP servers automatically?
The system uses connman as connection manager
I attatch screen shots of the request and ack messages
tcpdump command used:
tcpdump -i eth0 -n port 67 and port 68 -w capture.pcap -v
