Hi All,

I'm new to dhcp and am trying to get the daemon to start but get the following error from /var/log/syslog:

Sep 20 08:12:12 localhost dhcpd: No subnet declaration for eth0 (64.81.72.103).
Sep 20 08:12:12 localhost dhcpd: ** Ignoring requests on eth0. If this is not w
hat
Sep 20 08:12:12 localhost dhcpd: you want, please write a subnet declaration
Sep 20 08:12:12 localhost dhcpd: in your dhcpd.conf file for the network segm
ent
Sep 20 08:12:12 localhost dhcpd: to which interface eth0 is attached. **
Sep 20 08:12:12 localhost dhcpd:
Sep 20 08:12:12 localhost dhcpd:
Sep 20 08:12:12 localhost dhcpd: Not configured to listen on any interfaces!

This is my dhcpd.conf file:

# option definitions common to all supported networks...
option domain-name 64.81.72.103;
option domain-name-servers 64.81.79.1, 216.231.41.2;

default-lease-time 600;
max-lease-time 7200;

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;

# No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.

# This is a very basic subnet declaration.

subnet 64.0.0.0 netmask 255.255.255.0 {
range 64.1.1.1 64.1.1.254;
# option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;
#}

Please, any help is greatly appreciated.

Thanks,

ok - well there is obviously a problem with your configuration file.
I will just go and get mine off the server and post it for you and we can see the differences.

Ok, here it is:

Code:

# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
# option definitions common to all supported networks...
option domain-name "fastweb.it";
option domain-name-servers 213.156.54.80,213.156.54.81;
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
default-lease-time 3600;
max-lease-time 72000;
# if you do not use dynamical DNS updates:
#
# this statement is needed by dhcpd-3 needs at least this statement.
# you have to delete it for dhcpd-2, because it does not know it.
#
# if you want to use dynamical DNS updates, you should first read
# read /usr/share/doc/packages/dhcp-server/DDNS-howto.txt
ddns-update-style none;
ddns-updates off;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
#authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;

subnet 192.168.0.0 netmask 255.255.255.0 {

  host LO {
    hardware ethernet 00:04:75:D1:91:C1;
    fixed-address 192.168.0.21;
  }

  host VI {
    hardware ethernet 00:0C:6E:9C:C3:44;
    fixed-address 192.168.0.24;
  }

  host NI {
    hardware ethernet 00:11:2F:89:6F:CA;
    fixed-address 192.168.0.23;
  }

  host ED {
    hardware ethernet 00:0E:A6:C5:82:5F;
    fixed-address 192.168.0.22;
  }

  range 192.168.0.31 192.168.0.39;

}

As you can see, the IP address ranges 192.168.0.21-24 are given to specific
MAC addresses, and any guest to the network is given a number between 31 and 39.
Maybe all you need is the subnet mask declaration that I have!

Here is mine if it helps;

Code:

authoritative;
ddns-update-style interim;
subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.100 192.168.0.250;
    default-lease-time 259200;
    max-lease-time 518400;
    option subnet-mask 255.255.255.0;
    option broadcast-address 192.168.0.255;
    option routers 192.168.0.1;
    option domain-name-servers 192.168.0.1;
}

Also this for my setup;
/etc/conf.d/dhcp
(Set IFACE="eth0")

Thanks for the reply! I'll give this a look over and see if I can iron out my wrinkles.

Cheers,
