linux-DHCP服務(wù)器+中繼路由

1、精品文檔DHCP服務(wù)器上的配置（前提要能 PING通）首先安裝DHCPmount /dev/c：drom /mntrpm -ivh /mnt/Server/dhcp3*05-7.e15.1386*rpm安裝好后打開(kāi)DHCF配置文件：vi /etc/dhcpd.conf打開(kāi)后進(jìn)行相關(guān)的配置：先在末行模式下將 /usr/share/doc/dhcp-3.0.5/dhcpd.co nf.sample文件的內(nèi)容拷貝到 /etc/dhcpd.co nf 里面?？截愅旰?，在命令行模式使用 30yy命令拷貝從sub net開(kāi)始的30行內(nèi)容。 然后進(jìn)行下一步的配置；同理，這里寫上另外一個(gè)網(wǎng)段的IP:2歡迎下載
