在Redhat linux7.3下作动态DNS

jxwpx

大侠帮忙啊，郁闷了好几天了
我配置ddns,dns部分配置正常通过，而dhcp 部分报错，我的配置文件如下：dhcpd.conf

ddns-update-style interim;
ignore client-updates;
key wgzddns {
algorithm HMAC-MD5;
secret fDlgh+lCpcZOJ9P/wupblD6Fwb1KRXLNDBCOCWQu+Mw=;
};
zone abc.com. {
primary 127.0.0.1;
key wgzddns;
}
zone 140.98.10.in-addr.arpa. {
primary 127.0.0.1;
key wgzddns;
}
subnet 10.98.140.0 netmask 255.255.255.0 {
range 10.98.140.100 10.98.140.200;
option routers 10.98.140.254;
option subnet-mask 255.255.255.0;
option domain-name "abc.com";
option domain-name-servers 10.98.140.18,10.98.140.4;
default-lease-time 6000;
max-lease-time 12000;
}

系统报错如下：
