linux设置dhcp为临时租约,linux – 如何解决dhcp3中的“无免费租约”问题？

我没有面临免费租赁问题.我正在构建一个新服务器.我已经成功安装了ltsp.然后,我配置了dhcp.这是我的dhcpd.conf文件.

option subnet-mask 255.255.255.0;

option broadcast-address 192.168.12.255;

option routers 192.168.12.205;

option domain-name-servers 192.168.12.205;

default-lease-time 600;

max-lease-time 7200;

next-server 192.168.12.205;

option root-path "192.168.12.205:/opt/ltsp/i386/";

subnet 192.168.12.0 netmask 255.255.255.0 {

range 192.168.12.55 192.168.12.100;

host client1 {

option root-path "192.168.12.205:/opt/ltsp/i386/";

filename "/ltsp/i386/pxelinux.0";

hardware ethernet 00:1d:72:04:8d:a9;

fixed-address 192.168.12.69;

}

}

错误是,

Dec 27 18:18:35 Dennis dhcpd: Wrote 0 leases to leases file.

Dec 27 18:23:27 Dennis dhcpd: DHCPDISCOVER from 00:1d:72:04:8d:a9 via eth0: network 192.168.12/24: no free leases

我在互联网上提到并尝试过.但是,我无法修复.

你能指导我解决这个问题吗？
