ADSL拨号故障一例
打算在linux上加入ADSL拨号的功能,安装rp-pppoe后,拨号时出现如下错误:PPP error: "Couldn't set tty to PPP discipline"
经google search,发觉原来是内核的一个PPP模块未加载(ppp_async)
Device Drivers --->
Networking support -->
[*] PPP multilink support (EXPERIMENTAL)
<*> PPP support for async serial port 选中!
<*> PPP support for sync tty ports 选中!
一直以为这个模块是针对串口的,对 ADSL 拨号没用,为了减少内核大小所以就将它去掉了。看来对内核的裁减要更加小心仔细才行!
