dhcpd in IPv6 mode and syslog messages

[Алексей Прокопчук]

Good time of the day!

Few days ago I started to experiment with assigning IPv6 addresses to
hosts in my home network via DHCP.
When dhcpd running in IPv4 mode, I can see his messages in syslog as
follows:

Oct  4 03:02:01 router dhcpd: DHCPDISCOVER from 00:1d:60:75:f3:72 via eth0
Oct  4 03:02:01 router dhcpd: DHCPOFFER on 10.196.8.43 to
00:1d:60:75:f3:72 via eth0
Oct  4 03:02:01 router dhcpd: DHCPREQUEST for 10.196.8.43 (10.196.8.1)
from 00:1d:60:75:f3:72 via eth0
Oct  4 03:02:01 router dhcpd: DHCPACK on 10.196.8.43 to
00:1d:60:75:f3:72 via eth0

When dhcpd running in IPv6 mode, it's very quiet and I can't see any
requests or replies. I see only solicit messages and advertises. First
half hour I thought dhcpd doesn't work at all... Is there any way to
make dhcpd in IPv6 mode more verbose?

Thanks for attention, with best regards, Alexey Prokopchuk (AP8686-RIPE).
