freeradius 2.1.10 DHCP not responding

[Zietz, Marco]

Hi,

I'm playing with freeradius acting as DHCP-server - which is a
magnificent idea! 

Got a little problem getting it up and running. Already checked any
comments in sources, list archive, recent git patches related to dhcp
and my favourite search engine. Also used two different machines with
other nic's.
Used
ftp://ftp.freeradius.org/pub/freeradius/freeradius-server-2.1.10.tar.bz2
and followed directions in raddb/sites-enabled/dhcp. Configure, make and
make install with no errors/warnings. But radiusd does not react to any
DHCP-discover. I can see the discovers coming in via tcpdump but radiusd
-X remains quiet:

=============================
