(9)host

(10)00:24:D2:DF:37:F3

(11)192:168.1.102

【问题1】

Linux服务器中DHCP服务程序/usr/sbin/dhcpd对应的配置文件名称是dhcpd.conf,也是DHCP服务器的主配置文件,其默认在/etc目录下。

【问题2】

配置DHCP服务器,其中(3)空为默认租约期限,从图2-1中看出为2小时,所以第(3)空为7200,默认单位为秒。(4)子网掩码为255.255.255.0。(5)空为option routers配置网关,地址为192.168.1.1。(6)空为配置广播地址为192.168.1.255。(7)(8)配置域名服务器地址分别为218.30.19.50和61.134.1.4。

【问题3】

配置MAC和IP地址192.168.1.102的绑定,答案为host,00:24:D2:DF:37:F3,192:168.1.102。
