Linux查看dhcp服务器所出租过的IP信息

DHCP 伺服器會將所有出租過的 IP 資訊存放在 /var/lib/dhcpd/dhcpd.leases 中。我們來看看該檔案的內容：

lease 192.168.101.99 {
   starts 1 2005/10/03 01:47:16;
   ends 2 2005/10/04 01:47:16;
   binding state active;
   next binding state free;
   hardware ethernet 00:02:b3:1d:61:7a;
   uid "\001\000\002\263\035az";
   client-hostname "test-winxp";
}
lease 192.168.101.44 {
   starts 1 2005/10/03 02:09:40;
   ends 2 2005/10/04 02:09:40;
   binding state active;
   next binding state free;
   hardware ethernet 00:02:b3:26:ca:64;
   uid "\001\000\002\263&\312d";
   client-hostname "build";
}
