<b>Subject:</b> [Kea-users] kea-dhcp6 packet-level debugging help</span>
<div> </div>
</div>
<div style="font-size: 11pt;">Hello, I am writing a little program that acts like a DHCPv6 client and talks to the kea-dhcp6<br>
server over a dedicated virtual Ethernet interface pair. Since I am crafting the DHCPv6 client<br>
side packets locally, I would like to set UDP checksum to 0 so I don't have to bother with<br>
the Internet checksum. But, kea-dhcp6 seems to be ignoring my packets.<br>
<br>
Will kea-dhcp6 accept DHCPv6 Solicit messages with UDP checksum set to 0? And, does it<br>
have a debug facility that prints per-packet processing statistics? Right now, when I run with<br>
the "-d" flag set, I see nothing in the logfile when the suspect DHCPv6 Solicit message is<br>
sent - it seems like I should see something if kea-dhcp6 receives the packet, shouldn't it?<br>
<br>
Thank you - Fred<br>
