Hi,
If you set
"loggers": [
[...]
{
"debuglevel": 99,
"name": "kea-dhcp6.packets",
"severity": "DEBUG"
},
Then you should have a log such as:
2024-12-19 09:12:54.686 INFO [kea-dhcp6.packets/xx.xx] DHCP6_PACKET_RECEIVED
duid=[00:01:xxxxxxxxxxxx], [no hwaddr info], tid=xx: SOLICIT (type 1) received
from xxxx to xxx on interface eth1
Together with the content of the packet
msg_type=SOLICIT (1), trans_id=xx,
options:
type=00001, len=00014: 00:01:xxxxxxxxxxxxxxx
type=00003(IA_NA), len=00012: iaid=xx, t1=0, t2=0
[...]

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