Redhat DHCP 服务器通过不验证 MAC 地址来颁发 IP

我在 Redhat 卫星服务器上安装了 kickstart。在dhcp服务器上，我添加了一个redhat1来启动；在构建 redhat1 时，dhcp 服务器将 redhat1 的 IP 地址发布给未知主机（Windows 服务器）。这导致 redhat1 服务器的构建不完整。是什么导致 dhcp 服务器将 redhat1 的 IP 发布给第二台服务器？

# more /etc/dhcp/dhcpd.conf
option domain-name "build.local.com";
option domain-name-servers 10.10.3.9, 10.10.3.8;
default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;

subnet 10.10.3.0 netmask 255.255.255.0 {
        option subnet-mask 255.255.255.0;
        option routers 10.10.3.1;
        range 10.10.3.80 10.10.3.85;
}

host redhat1 {
        hardware ethernet 00:50:56:B7:7A:4D;
        fixed-address 10.10.3.83;
}

allow booting;
allow bootp;
next-server 10.10.3.90;
filename "/pxelinux.0";

以下是 IP 10.10.3.83 的 /var/log/messages 文件条目

答案1

10.10.3.83嗯，窗户盒以前是否偶然被租用过（dhcpd.leases可能表明这一点）？不知道会出现什么问题，因为我将任何fixed-address分配保留在 中列出的任何地址之外range。
