关于cygwin下skyeye的网络模拟问题请教

halloween

如果宿主机操作系统是linux需要加载tun.o模块，那么在cygwin上面没有设备，需要安装其它的什么组件么？

如果不需要，我使用Skyeye V1.2Rel 编译成功的skyeye.exe运行testsuite2.1下面的at91/uclinux_rtl8019时，启动画面如下：

从启动画面的提示看是没有找到相关的设备吧，请教一下是什么问题？谢谢

ksh

It seems netcard simulation is not supported in cygwin environment.

halloween

那请教一下在Windows操作系统上面还有什么方法可以让skyeye支持网卡模拟？谢谢

ksh

According to koodailar's anwser, he think MingW environment can let skyeye support netcard simulation on windows. But I have not try it. Good luck!

halloween

谢谢，我已经成功的尝试了在MinGW下面的网卡模拟尝试，主要是要先安装VPN里面的TAP-WIN32，作为网卡虚拟共享。

不过遗憾的是SkyEyeV1.2Rel还是不能够直接在MinGW下面编译通过，关于这个问题我已经提交bug到sourceforge了

ksh

Thanks.  I will look into it.
Can you write your experince here about netcard simulator under MinGW to share with us? That will be very kind.

目前 TAP-WIN32 在 SkyEye 下还是不能使用的，
原来 koodailar 写的这个东西好像有点问题。

过段时间我会把 SkyEye 的 MinGW 环境代码彻底清理一下，
到时我会考虑去除 OpenVPN 依赖，转而使用 Win32 DDK 的东西或类似 vnet 等代替。

请期待下一版本...
