Hi,

I try to use the DHCP functionality of the Freeradius server. Server is
unable to parse somethink.
Could you please help me, thx.

*Configuration:*
1. interface eth1 net 192.168.0.1 mask 255.255.255.0
2. the newest version of freeradius ( from git )
3. configuration
*
sites-available/dhcp:*
server dhcp {
listen {
	ipaddr = *
	port = 67
	type = dhcp
	interface = eth1
	broadcast = no
}

#  Packets received on the socket will be processed through one
#  of the following sections, named after the DHCP packet type.
#  See dictionary.dhcp for the packet types.
dhcp DHCP-Discover {
	update reply {
	       DHCP-Message-Type = DHCP-Offer
	}

	#  The contents here are invented.  Change them!
	update reply {
	        DHCP-Domain-Name-Server = 192.168.0.1
	        DHCP-Domain-Name-Server = 192.168.0.2

	#  module.

	#  If the MAC wasn't found in that list, do something else.
	#  You could call a Perl, Python, or Java script here.

}

	update reply {
	       DHCP-Message-Type = DHCP-Ack
	}
