這是dhcp 的設定檔...不用刻意記啦...因為它有sample...用 slocate dhcp 就可以看到...
#slocate dhcp
#cp /usr/share/doc/dhcp-2.0pl5/dhcpd.conf.sample /etc/dhcpd.conf
版上留的是個人的設定啦...下次要用比較快...

range dynamic-bootp 192.168.20.3 192.168.20.100;
# we want the nameserver to appear at a fixed address
host netserver
{
hardware ethernet 00:20:ED:42:31:B6;

}
}詳細說明不用再自己打啦...看一下鳥哥的或netman 的文章就很精彩...

這次為什麼會弄這一篇...原因是昨晚弄很久...記得設定很簡單呀...dhcp run
起來也很正常呀...可是 client 端就是無法自動取得 IP...後來正準備放棄去睡
覺前...把整個 Firewall 打開...竟然就正常了...原來是被自己的 Firewall 擋掉了..
難怪就是無法取得 IP...真是的...我的防火牆是整個擋掉...再各別開的那種...
所以 udp 67 port 是擋掉的...只要把它打開..
# Allow DHCP
iptables -A INPUT -p udp --dport 67 -j ACCEPT
這樣就行啦...寫下來當個警惕囉...
