DHCPD Won't start.

pdeman2 · 04-30-2006, 08:54 PM

I've used DHCPD before, but this time, it simply won't start. I use the command /etc/init.d/dhcpd start, and it just says: Starting dhcp: [FAILED]. Here's the dhcpd.conf:

Code:

#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
# Green Side
subnet 192.168.1.0 netmask 255.255.255.0 {
        option domain-name-servers 24.92.226.9;
        option broadcast-address 192.168.1.255;
        option subnet-mask 255.255.255.0;
        option routers 192.168.1.1;
        range 128.168.1.100 192.168.1.150;
        }

Thanks.

Run it yourself, instead of letting the initscript do it, and you might get some better error messages:

Code:

dhcpcd eth0

First check your network configuration....and IP address

Ok, eth1 looks OK:

Code:

eth1      Link encap:Ethernet  HWaddr 00:07:E9:0F:6F:16  
          inet addr:192.168.1.1  Bcast:192.168.255.255  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

Here's the output of dhcpd eth1:

Ah, you have a typo, which I didn't notice before. See, the first number in your "range" is 128 instead of 192.

pdeman2 · 05-01-2006, 01:15 PM

Okay, two things did it; the ddns-update-style thing, and the typo. Thanks for the help.

baboooss · 05-01-2006, 11:10 PM

Your address range is wrong in dhcp configuration .Change starting address to 192 instaed of 128

that will work

pdeman2 · 05-02-2006, 10:55 AM

Yeah, got it.

Greetings,

I have my own dhcpd.conf file edit similar to the one above;..

I have the foll0wing lines ...ex:

ddns-update-style interim;
ignore clients-updates;

DHCPDARGS=eth1; # server eth1 manually set to 192.168.1.10/24

subnet 192.168.1.0 mask 255.255.255.0 {
option routers
option subnet-mask 255.255.255.0;
option domain-name-servers 192.168.1.10;
default-lease-time 43200;
max-lease-time 86400;
}

when i try and start the service...it fails...when running the dhcpd eth1, i get "no subnet declarations for eth1 (192.168.1.10)

can anyone provide any assistance on this

Is there a semicolon missing after option routers?
