    My first post here, so Gidday All:

    I am running Fedora 4 as a dhcp server with the following config:

    eth0 - WAN (Settings from ISP via DHCP)
    eth1 - LAN (Static IP

    Currenty in my dhcpd.conf file I have the following line:

    option domain-name-servers,;

    The IP's of the nameservers here are the ones my ISP sends to eth0 via dhcp, which I have entered manually.

    Is there a way to get this dynamically updated from the settings my isp sends to eth0? (ie:If my isp changes its dns server IP's I want all my lan clients to also get updated with the new dns server ips, without me changing this manually in the dchpd.conf file)

    Here is a listing of my dhcp.conf file:

    ddns-update-style none;
    # DHCP Server Configuration file.
    # see /usr/share/doc/dhcp*/dhcpd.conf.sample
    ption domain-name-servers,;

    # Lan
    subnet netmask {
    option netbios-name-servers;
    option routers;
    option domain-name-servers,;

    Any help greatly appreciated

    I don't know of such a feature, but I think it's very, very unusual if an ISP changes his name server IP addresses - something like that would cause him to do a lot of support for confused customers, and I don't think he wants to do that.

    Hi Falko,

    I will leave it as it is and see it goes. I suppose I could always set up a DNS server, but I am trying to keep it simple as I have limited time to spend on this project.
