我搞 F460 / F660 最初为了编译 tun.ko 来支持 OpenVPN，试了几次都是 tun.ko 插入不了内核，报错是缺少一些的基本的 tun.ko 需要的调用
WKA高手现身，看来我离成功近在咫尺了呵呵。
我只编译过usblp.ko,不知道这个tun.ko能不能成功，试试吧

wka你好，我尝试编译了一下tun.ko,在我的F660里面可以正常加载了，能不能用我没法试验，你自己试试吧！

我编译的tun.ko如下：

WKA,经过几天努力，这个版本的tun.ko在我的F660上终于不报错重启呢，你试试看呢？

附上 openvpn
支持，建议能好好开发HG8245的功能。不光是打印机，最好是能把固件修改成Open. DD，或者Tomato的。
这样我等用户就有福了。

没有把加密和认证编译进去？

在2.6的内核中，默认的虚拟接口是tunl0，但是通过阅读OPENVPN的代码，它默认的接口是tun0，所以会找不到设备，发生以上错误。
解决方法：手动指定网络接口
在/etc/init.d/openvpn（openvpn的启动脚本）中，找到$openvpn --daemon --writepid ...这行，加上参数$openvpn --dev tunl0 --daemon --writepid ...，这样就可以了。

没有。为省系统资源，最小化编译
