有关dhcp的问题!
系统是RedHat9.0。
小弟这两天在弄DHCP服务器,但是在配置dhcpd.conf后,输入命令:dhcpd restart 总是有如下提示:[root@wanglin etc]# dhcpd restart

No subnet declaration for restart (0.0.0.0).
** Ignoring requests on restart. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface restart is attached. **


Not configured to listen on any interfaces!

其中有一句是:Not configured to listen on any interfaces!,不知道为什么会出现这样的提示,请各位高手帮忙看看,dhcpd.conf的配置如下:
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#

# option definitions common to all supported networks...
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;

ddns-update-style ad-hoc;
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.

subnet 192.168.10.0 netmask 255.255.255.0 {
}

# This is a very basic subnet declaration.

subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.2 192.168.0.100;
option routers 192.168.0.1;
option broadcast-address 192.168.0.255;
}

# This declaration allows BOOTP clients to get dynamic addresses,
# which we don't really recommend.

subnet 192.168.0.0 netmask 255.255.255.128 {
range dynamic-bootp 192.168.0.40 192.168.0.60;
option broadcast-address 192.168.0.127;
option routers 192.168.0.1;
}

# A slightly different configuration for an internal subnet.
#subnet 192.168.10.0 netmask 255.255.255.0 {
# range 192.168.10.51 192.168.10.60;
# option domain-name-servers ns1.internal.example.org;
# option domain-name "internal.example.org";
# option routers 192.168.10.1;
# option broadcast-address 192.168.10.255;
# default-lease-time 600;
# max-lease-time 7200;
#}

# Hosts which require special configuration options can be listed in
# host statements. If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.


# Fixed IP addresses can also be specified for hosts. These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP. Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.


# You can declare a class of clients and then do address allocation
# based on that. The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.

另：我机器的IP地址（即DHCP服务器）是192.168.0.102。
谢谢!

什么都不懂

看起来是你配置的地址范围有问题，你配置的地址是从哪到哪的？

好好先生

把这两段注释掉,重启dhcpd试试.

非常感谢大天使，DHCP已经做好！
