Help with getting a simple dhcp server working

GUIPenguin · 02-08-2006, 01:43 PM

I am running gentoo
this is my /etc/dhcp/dhcp.conf file

Code:

log-facility local7;
ddns-update-style none;
use-host-decl-names on;

subnet 192.168.1.0 netmask 255.255.255.0 {
        option domain-name "cluster";
        range 192.168.1.10 192.168.1.99;
        option routers 192.168.1.100;

        host node01 {
                # MAC address of network card on node 01
                hardware ethernet 00:D0:B7:BB:F8:DD;
                fixed-address 192.168.1.1;
        }
}

I have set the correct interface in /etc/conf.d/dhcp for eth0
in /etc/conf.d/net I have set for eth0

Code:

iface_eth0="192.168.1.100 broadcast 192.168.1.255 netmask 255.255.255.0"

/etc/init.d/dhcp restart after each configuration change I get

Code:

master ~ # /etc/init.d/dhcp restart
 * Stopping dhcpd ...                                                     [ ok ]

master ~ #

/var/log/messages shows the same and nothing else
So I see that it is listening on the correct interface (eth0)

I have a ethernet cable from eth0 to a switch and then my client (node01) off that switch trying to get dhcped. Why is my client not getting dhcped?

I would really like any help with getting this dhcp server working properly. Thanks

Did you try to connect your box directly to your server (with cross-cable), just to find out it ain't a problem with your switch between them..
Otherwise try to do it static(you're shure the hardware is ok)(with or without switch)some switches are able to ping through network (with serial cable and the app. minicom)
It seems a workable setup,so maybe this will help?

You could try something like;

Code:

# nano /etc/dhcp/dhcpd.conf
(Here is a sample configuration file:)
authoritative;
ddns-update-style interim;
subnet 192.168.1.0 netmask 255.255.255.0 {
    range 192.168.1.101 192.168.0.250;
    default-lease-time 259200;
    max-lease-time 518400;
    option subnet-mask 255.255.255.0;
    option broadcast-address 192.168.1.255;
    option routers 192.168.1.100;
    option domain-name-servers 192.168.1.100;
}
# nano /etc/conf.d/dhcp
(Set IFACE="eth0")
# rc-update add dhcp default
# /etc/init.d/dhcp start
