Android中配置OpenVPN的方法总结
如果你能够访问Android Market，那么以下步骤不必做
1、下载http://github.com/downloads/fries/android-external-openvpn/openvpn-static-2.1.1.bz2
2、解压缩获得openvpn-static-2.1.1，执行adb push openvpn-static-2.1.1 /system/xbin/openvpn
3、adb shell，执行chmod 775 /system/xbin/openvpn上面步骤1-3可以用root explorer解决把openvpn-static-2.1.1改名为openvpn,放入/system/xbin, 放入前先按右上角的remount r/w，点这个openvpn长按，选Permissions，改权限为 第一排三个勾，第二排三个勾，第三排，第一和第三打勾
如果能够访问Market，请从这里开始阅读
在Market搜索并下载OpenVPN Settings Installer （图标和OpenVPN Settings相似的那个）并运行，点Install。
如果运行Install之后结果显示Binary Located并且图标变绿，请继续：
检查是否有busybox
打开终端，输入su，授权
提示符变为#后，输入
busybox which busybox
如果返回一个类似
/system/bin/busybox
的结果，说明已经安装了busybox，下面的安装busybox的步骤可以跳过
打开终端，输入su，授权
提示符变为#后，输入
busybox which busybox
如果返回一个类似
/system/bin/busybox
的结果，说明已经安装了busybox，下面的安装busybox的步骤可以跳过
如果不能访问Market，请按照下面的方法安装busybox
下载安装busybox（附件）
安装方法：
解压，把busybox这个文件用root explorer拷入/system/bin/
更改其权限为：第一排三个勾全打，其余勾消掉。
如果能够访问Market，请用下列方法安装busybox：
从这里下载busybox安装程序，并运行之.
busybox安装完成后，开终端
su
busybox which busybox
会返回你busybox的安装路径，比如我的是
/system/bin/busybox
把这个路径记下来
su
busybox which busybox
会返回你busybox的安装路径，比如我的是
/system/bin/busybox
把这个路径记下来
busybox mkdir /system/xbin/bb
ln -s /system/bin/busybox /system/xbin/bb/ifconfig
ln -s /system/bin/busybox /system/xbin/bb/route
ln -s /system/bin/busybox /system/xbin/bb/ifconfig
ln -s /system/bin/busybox /system/xbin/bb/route
最后两行命令，开头字母是小写L，不是小写I，要注意。
至此安装完成，在sd卡根目录建立openvpn文件夹，把发给你的四个文件（两个crt，一个key，一个ovpn）放入这个文件夹中，去Market下载TunnelDroid 用这个连接下载TunnelDroid http://cn.drop.io/vpnfiles/asset/net-sourceforge-tunneldroid-apk，暂时不要从Market更新，点menu-Preferences，Set DNS，填入 8.8.8.8，OK，返回。点 xxx.ovpn连接。
如果提示没有驱动（比如Milestone，请以“机型”“OS版本”这两个为关键字查找tun.ko这个文件。
这个是Milestone用的tun.ko，适用于2.1系统。
这个是Milestone用的tun.ko，适用于2.1系统。
