    dhcp3 problems


    I've got two connections:

    ifconfig:

    /etc/network/interfaces:


    # The loopback interface
    auto lo
    iface lo inet loopback

    # The first network card - this entry was created during the Debian installation
    auto eth0
    iface eth0 inet dhcp

    auto eth1
    #iface eth1 inet dhcp
    iface eth1 inet static
    address 192.168.0.5
    netmask 255.255.255.0
    network 192.168.0.0
    broadcast 192.168.0.255
    # subnet 192.168.0.0

    When i start dhcp3-server i get the following error messages:

    /etc/init.d/dhcp start
    Starting DHCP server: dhcpd failed to start - check syslog for diagnostics.

    cat /var/log/syslog
    Jun 2 00:00:59 FIREWALL dhcpd: No subnet declaration for eth1 (192.168.0.5).
    Jun 2 00:00:59 FIREWALL dhcpd: Please write a subnet declaration in your dhcpd.conf file for the
    Jun 2 00:00:59 FIREWALL dhcpd: network segment to which interface eth1 is attached.
    Jun 2 00:00:59 FIREWALL dhcpd: exiting.

    So tried to configure my /etc/dhcp3/dhcpd.conf

    /etc/dhcp3# more dhcpd.conf

    option domain-name "ATHOME";
    option domain-name-servers toccata.fugue.com;

    option routers 192.168.0.5;
    option broadcast-address 192.168.0.255;
    option subnet-mask 255.255.255.0;

    default-lease-time 1209600; # 2 weeks
    max-lease-time 1814400; # 3 weeks

    #subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.6 192.168.0.254;
    #}

    option domain;

    option domain-name-servers 194.159.73.135,194.159.73.136;

    authoritative;

    But i still get error messages on my dhcp server. I tried allready everything. Does somebody know how to fix this, please?

    You have to declare your subnet. Change your dhcpd.conf:

    default-lease-time 1209600; # 2 weeks
    max-lease-time 1814400; # 3 weeks

    subnet 192.168.0.0 netmask 255.255.255.0 {
    option domain-name "ATHOME";
    range 192.168.0.6 192.168.0.254;
    option routers 192.168.0.5;
    option domain-name-servers 194.159.73.135, 194.159.73.136;
    authoritative;
    }
