dhcp server not respoding with time server option

[S Kalyanasundaram]

DHCP server does respond only with the requested option? 

In my dhcp configuration i have router and timerserver options. But when
i do a dhcpdump it shows only option 3 [router] has been received. The
dhcprequest sent by the client does not have option 4[timeserver] in its
parameter request list anyway. Looks like dhcp server only responds with
the requested options by the client.

I am not using dhclient, I am using the dhcpcd client and dhcpcd-test
tools.

Here are the request and ack packets.

I dont know why the error in packet message comes. But i dont see any
proplem in getting a reply from dhcp server. 

Is there a way I can force the dhcp server to send all the options
independent of what dhcp client asks?

Thanks,
