NetBSD 6.0.1 DHCP 获取地址失败，静态配置 IP 成功
最近在本本上装了 NetBSD 6.0.1。奇怪的是，地址 dhcp 方式获取不了，静态配置可以。哪位达人指点一下，先行谢过。在系统启动的时候有这样的打印:
route: writing to routing socket: network is unreachable
google 了一下，找到一个FreeBSD 上类似的问题，但看半天没看懂人家咋解决的：

静态配置时的，rc.conf 相关内容：
rc_configured=YES
# Add local overrides below
#
hostname=NETBSD
# ifconfig_wm0=dhcp
ifconfig_wm0="inet 192.168.1.120 netmask 255.255.255.0"
sshd=YES
ntpd=NO
wscons=YES
defaultroute=192.168.1.1
dhcp 方式时的 rc.conf:
rc_configured=YES
# Add local overrides below
#
hostname=NETBSD
ifconfig_wm0=dhcp
# ifconfig_wm0="inet 192.168.1.120 netmask 255.255.255.0"
sshd=YES
ntpd=NO
wscons=YES
# defaultroute=192.168.1.1
执行
# /etc/rc.d/network restart
后的输出：

没有用过NetBSD，由于在Windows和OpenBSD下面也碰到类似问题，分享个人经验
先假设
1、你在NetBSD下面的dhcp配置是正确的
2、局域网的dhcp服务正常。
dhcp无法获取ip，静态配置可以，在有线网络和无线网络我都碰到过
可能原因
有线网络
1、网卡质量差
2、网线质量差
3、网线过长。
无线网络
1、网卡质量差
2、无线信号差，如AP和电脑距离过远。 回复 2# f5b
这个系统本身我就是利用 PXE，从网络安装的，安装的时候 dhcp 可以正常工作。所以可以排除是硬件问题。我个人认识应该是软件问题，可能和 ipv6 或者 route 有关系。
不管如何，还是谢谢您的回复 :-) 有个日本人碰到的问题和我的很像：
http://d.hatena.ne.jp/steleto/20101225/1293291400 刚才抓了个包看了一下，实际上接口已经收到 dhcp ack 了，但又重新做了三个周期后才停止

问题解决了，应该是配置有问题导致的，调整后的 rc.conf 如下：
rc_configured=YES
# Add local overrides below
#
hostname=NETBSD
dhclient=YES
# ifconfig_wm0=dhcp
wscons=YES
sshd=YES
ntpd=N
和原先的相比，多了 dhclient=YES, 少了 ifconfig_wm0=dhcp (这句是系统装好后就有的)
另外，wifi 接口还没配，如果不给 dhclient 指定接口的话，好像会一直尝试配置 wifi 接口，如果配置不成功，终端一直会有错误信息打印，挺烦人的。所以最好/etc/dhclient.conf 里指定接口
这个文件，我的系统里也没有，新建了一个，内容如下：
interface "wm0" {
send-dhcp-client-identifier "client-wm0";
}
好像用dhcpcd 来配置也可以，尝试了一下，没有成功，懒得折腾了，还是老老实实用 dhclient 了。
记得在安装过程中，好像有提示是否要把 dhcp 配置的网络信息写入 /etc ，当时选了否。也许当时选了是，就没有问题了。哎，人生就是折腾啊
