OpenBSD中作DHCP client时的问题

弱智

如题，purge今天碰到问题：
在一台双网卡pc上面设置NAT；
安装到网卡设置，外网网卡是dhcp client，
系统也能自动侦测出DHCP 服务器是10.0.0.2，
但是迟迟不能分配到地址，（在linux和winxp都可以分配到10.3.5.x）
出现"Invalid lease option"，
然后结束。

也找了google和 bsdforums.org上面的一些，不太明白。
望指教，谢谢。

我没用过OpenBSD，但我用FreeBSD也是使用动态IP的，也是有两张网卡。我发现FreeBSD使用DHCP时需要调动/sbin/dhclient-script，你可以检查一下这个文件。

Hi, there,
you said: you can see the correct default gateway, right? But after that, everything should be automatic. How come can't get dynamic IP ? It really makes my head crack.
How did you install your OB? I mean by CD or boot from a floppy and install by FTP ( I used this one)? I installed my OB in our LAN. There are three networks in our router. Two  for outside, one for internal ( IP is 192.168.1.1 ). So, I give you my dhclient.conf. Maybe can give you any idea. It is default setting and I didn't change it.

dhclient.conf:
...
initial-level 1;
send host-name "peter";
request subnet-mask,
              broadcast-address,
              routers,
              dimain-name,
              domain-name-servers,
              host-name;

我觉得多半还是 /etc/dhclient.conf 的问题。试试加上

send host-name "hostname";

已经把vr0和rl0更换了，也不行，一样的提示。
看样子和网卡的质量无关。
只好手动设置了静态ip地址用着先。
谢谢。

to peter333:
something wrong with my NIC?
maybe is the ........ QUALITY of NIC

i use the NIC which vendor sting is "VIA Rhine III" and OBSD alias it as "vr0", just link into the external server gives me dynamic ip address.

another NIC for my private network, uses the NIC which the chipset's "Realtek 8139D", it works better for internal link.

原帖由 "弱智" 发表：
重新安装到设置网卡的地方，设置为dhcp方式获取ip地址就出现这样的提示：
DHCPOFFER 10.0.0.2，
这是正确的dhcp网关地址；
但是随后迟迟不能获得本地ip地址。
而且这还未到拷贝文件那一步，所以，应该是和pf没有..........

You are right. It's not PF problem. Yesterday, I installed Openbsd 3.4 by FTP in our LAN. Just setup outdide network interface to "dhcp". That's it. It works great.
For your situation, did you connect the cable? or something wrong with your network card? or something wrong with your connection?

自己觉得还是要再看看FAQ。
再次谢谢诸位弟兄的提示和帮助。
