Hello listmates,

I am running DHCPD for IPv4 on a Centos 5 machine. I am wondering if
anyone
has got a functional dhcpd.conf configuration serving static routes to
Linux, Mac OS X and Windows clients.

I tried a couple of variations of static-routes options - but have yet to
create something that would work.

Use this:
ddns-domainname "mydomainname.com";
ddns-update-style interim;
ddns-rev-domainname "in-addr.arpa";
ddns-updates on;
ignore client-updates;

key DHCP_UPDATER {
    algorithm hmac-md5;
    secret xxxxxxxxxxxxxxxxxxxxxxxxxxxx;
};

zone mydomainname.com. {
    primary 192.168.1.10;
    key DHCP_UPDATER;
}

zone 1.168.192.in-addr.arpa. {
    primary 192.168.1.10;
    key DHCP_UPDATER;
}

subnet 192.168.1.0 netmask 255.255.255.0 {
    authoritative;
    # --- default gateway
    option routers 192.168.1.1;
    option subnet-mask 255.255.255.0;
    option nis-domain "mydomainname.com";
    option domain-name "mydomainname.com";
    option domain-name-servers 192.168.1.1 , 192.168.1.2 ;
    option time-offset -18000;
    option ntp-servers 192.168.1.2;
    option netbios-name-servers 192.168.1.10;
    range dynamic-bootp 192.168.1.64 192.168.1.127;
    default-lease-time 21600;
    max-lease-time 43200;
}
    # we want the nameserver to appear at a fixed address
    host iPhone {
        next-server iPhone.mydomainname.com;
        hardware ethernet 00:24:36:49:42:81;
        fixed-address 192.168.1.192;
        }
    host Australia {
        next-server australia.mydomainname.com;
        hardware ethernet 00:24:8c:81:0c:15;
        fixed-address 192.168.1.202;
        }
    host D610 {
        next-server D610.mydomainname.com;
        hardware ethernet 00:90:4b:c7:54:fb;
        fixed-address 192.168.1.201;
        }

Hope this helps



Rob,

Thanks, looks good. But what part of it deals with static routes for
particular networks? All I see is one default gateway:

option routers 192.168.1.1;
The subnet ip4address/mask {.......} defines the information that is available to the clients for that subnet. The host clientname { .....} defines the static ip address and name to be used for a given ethernet.

Boris.
