网通dhcp客户端设置详解(转)[@more@]先说明我是新手套用了别人的方法修改而成。先向给我回复问题的朋友表示谢意
如果系统安装的时候如果选的是自动 dhcp方式设置网通的客户端可按以下方式设置，可以把我下面的方法直接复制粘贴到终端即可。

1.打开http://218.29.0.252/self.html

下载那个官方的’Linux客户端软件安装包2005‘里的linux客户端（就是没有标for XXX的那个）

2.把下载的压缩文件解压到home目录内(注：在linux下可能解压错误，可先在windows下解压后，复制、粘贴到home目录下）。我是装的双系统先装win2ooo,后装的新华镭1.5系统。

3.从开始－附件打开终端窗口输入： export RACERC=/home／racer(这个就是解压的文件名） 回车

在输入 export PATH=$PATH:/home／racer 回车 （注：这样上面两个上面两个环境变量都加到了当前用户下了。）

在输入 $dest_path/racer/ecou.sh start 回车 （这个为客户端登陆）回车后就会出现如下提示
All names of your net interface installed
-----------------------------------------
eth0 0
Input one name to hace access with Internet (eth0): 在回车就会自动检测adsl猫的配置信息例如：自动获得的IP 网关，子网等；在提示符下，输入账号、密码（注：密码输入时看不到，分清大小写）输入完后回车；打开浏览器就可以上网了我现在就时在新华镭系统发的这个帖子。 我的详细配置过程如下：
wo:~# export RACERC=/home/racer
wo:~# export RACERC=/home/racer
wo:~# $dest_path/racer/ecou.sh start
All names of your net interface installed
