在ARMLINUX上移植PPPOE碰到的问题

altmayer

我用的是MATRIX IV 开发板。
操作系统是 arm-linux
按PPPOE安装需要，内核加入了ppp,socket 等选项。
将rp-pppoe-3.5 编译好后运行出现下面的错误提示：
pppoe: Timeout waiting for PADO packets

下面是用strace跟踪的结果
[root@webeye-alt /]# strace pppoe -A -I eth0

可以保证我的网线是插好的，ADSL服务在REDHAT下面是正常使用的，为什么这个板子总是TIMEOUT呢？

看看你發出的PADI的封包對不對? 我也有遇到一些問題. 見問題如下:

去原公司问问,不一定是软件的问题.
