无法根据选项参数分配 IP 地址

我有这个 DHCP 配置文件：

authoritative;
option domain-name "XXX.XXX.XX";
allow bootp;
ddns-update-style ad-hoc;
class "karpuz-kabugu"
{
    match if (substring (option user-class, 0, 6) = "karpuz");
    log (info, "karpuz-kabugu");
}
        subnet 10.6.1.0 netmask 255.255.255.0  {
                pool {
                        range 10.6.1.10 10.6.1.99;
                        allow members of "karpuz-kabugu";
                }

                pool {
                        range 10.6.1.100 10.6.1.250;
                        allow unknown-clients;
                }

                option broadcast-address 10.6.1.255;
                option routers 10.6.1.1;

}

我想要做的是根据用户类别（选项 77）租用 IP 地址。我已使用以下命令在 Windows DHCP 客户端上设置了用户类别 IDipconfig /setclassid

我还karpuz使用 wireshark 查看了 DHCP 选项 77 中的设置。

dhcp日志内容如下：

May 27 17:09:22 2013 dhcpd: DHCPACK to 10.6.1.250 (00:1c:23:b5:da:71) via eth4

如您所见，我的客户端被分配了 IP10.6.1.250地址，但我期望的 IP 地址10.6.1.10介于10.6.1.99

我究竟做错了什么？

答案1

Dhcp 语句，如手册页中所述，仅允许从配置中allow unknow-clients没有声明的客户端获取 IP 地址。这是默认的。所以，我猜首先要从池声明中删除这样的语句。其次，尝试将语句添加到该池中。您的池配置应该是这样的：hostdeny

pool {
        range 10.6.1.10 10.6.1.99;
        allow members of "karpuz-kabugu";
      }

pool {
        range 10.6.1.100 10.6.1.250;
        deny members of "karpuz-kabugu";
     }
