[ml ml <mliebherr99@googlemail.com>]

Hello List,

i set up a DHCP Server. Here are my installed packages:
----------------------------------
Server:~# dpkg -l  | grep dhcp
ii  dhcp3-client                         4.1.1-P1-15+squeeze2
ISC DHCP server (transitional package)
ii  dhcp3-common                         4.1.1-P1-15+squeeze2
ISC DHCP common files (transitional package)
ii  dhcp3-server                         4.1.1-P1-15+squeeze2
ISC DHCP server (transitional package)
ii  isc-dhcp-client                      4.1.1-P1-15+squeeze2
ISC DHCP client
ii  isc-dhcp-common                      4.1.1-P1-15+squeeze2
common files used by all the isc-dhcp* packages
ii  isc-dhcp-server                      4.1.1-P1-15+squeeze2
ISC DHCP server for automatic IP address assignment

I am getting this error:
----------------------------------
dhcpd: DHCPINFORM from 192.168.99.111 via eth0: not authoritative for
subnet 192.168.99.0
dhcpd: If this DHCP server is authoritative for that subnet,
dhcpd: please write an `authoritative;' directive either in the
dhcpd: subnet declaration or in some scope that encloses the
dhcpd: subnet declaration - for example, write it at the top
dhcpd: of the dhcpd.conf file.

This is my config:
----------------------------------

}
host foo6 {

  fixed-address 192.168.99.103;
}
