这是我手工刷新的情况！dhcpcd -n

这个我没有手工刷新，最后一步我执行了dhcpcd -n，那是因为产生了一个DHCP_NAK

不知道为什么dhcpcd续约总是续几次就失败，然后再过6000秒就失去IP。

ikoody

我把dhclient安装上，按轩子兄说的，修改ifcfg-eth0将bootp改来no,结果还是用的dhcpcd,而不调用dhclient！

轩子

ECOU调的就是dhcpcd,
启动后用dhclient命令,续约

轩子

ikoody兄,你大约多长时间dhcpcd -n一下???

ikoody

就是自己不干预的话，dhcpcd一般能刷二到三次，这样就二三十分了，再加上最后一次刷新后还有6000秒的租期，所以一般都能上70分以上，好的时间更长一些！

我用一个脚本试验了一下，每两钟调用一次dhcpcd -n，多次试验，最多的一次刷了7次！刷新失败后还能用一个小时，若此时接着用dhcpcd -n 刷新，就换成私有IP了！
暂时搞不清原因！

最初由 轩子 发表

这一点我知道，ECOU调用dhcpcd! 但dhcpcd好像并不调用dhclient!当我只装有dhcpcd时，一样能续约，当然仍不能长时间续约，次数很有限!
当装上dhclient，并修改ifcfg-eth0这个配置文件为BOOTPROTO=none，此时根本不会调用dhclient续约！
另一种情况，设置BOOTPROTO=dhcp时，总是出现receive_packet failed on eth0: Network is down

是不是因为dhcpcd的版本不同造成的！轩子老弟用的是那个版本的dhcpcd？

轩子

我是说,启动后,你输入命令,dhclient,

我的dhcpcd是在它主页下的

http://www.phystech.com/download/dhcpcd.html

如果,设成DHCP开机,系统启动的时候,dhclient由ifup启动.

个人认为,dhcpcd这个客户端自己不会release(续约)
renew可能有几次

ikoody兄,脚本俺不会,你贴出来让看看
