結果綁定的客戶端ip是10.0.0.38 主機名也不對。

bjstry

操作系統(tǒng)是centos 6.5

dengbao2001

綁定IP，是跟MAC，與主機名無關

bjstry

    這點我當然知道，我是用mac地址綁定ip地址，順便設置一下主機名。

misihua

10.0.0.38是之前此機器在用的ip吧。可能在網絡上還有廣播。

    對，以前就是這個ip

misihua

你應該知道怎么做了吧？顯然不是DHCP配置的問題。

重啟網絡設備和電腦，要不先重啟電腦試下。

chenyx

客戶機renew重新從dhcp獲取下ip看看

    謝謝，我已經知道了問題就在這一行
DHCPREQUEST for 10.0.0.38 (10.0.0.126) from 00:30:67:55:ad:69 via eth0: lease 10.0.0.38 unavailable.
局域網內另外一部dhcp服務器10.0.0.126已經搶先分配ip 10.0.0.38給它了。
