dhcpcd-discuss

Hi Roy,

Thanks for your quick reply.

I need to send Information-request options only through DHCPv6 "Information-request" packet type as shown in the attached (DNS_Options_ScreenShot_with_INFOREQ_pkts.png) Screen shot.
But, from the "dhcpcd", these information-request options were sent as part of "DHCPv6 Solicit" packet type as shown in the attached (DNS_Options_ScreenShot .png) Screen shot.

As I understood from your previous reply, dhcpcd specifically does not support "DHCPv6 Information-request" packet type to send/query information-request options, and these options are provided only as part of DHCPv6 Solicit/DHCPv6 Reply packet type. Is it correct?

Regards,
Rajesh M P

I don't know how the TAHI test case works, but dhcpcd will only perform an Information Request packet on the receipt of a Router Advertisement packet with the O bit set.

There is no user interface to request this kind of packet by hand.
Is this what you are looking for - a means to manually request this?
