OpenVPN在Windows下使用User/Pass验证

OpenVPN在Windows下使用User/Pass验证

对于Windows下使用User/Pass验证已经是很久以前的承诺了，因为一开始一直都是在找寻
使用CMD(bat)文件检查用户名/密码的方式，但是一直没有结果，最后使用C写了一个小程
序实现用户名/密码验证。

Windows安装OpenVPN是很容易的，OpenVPN GUI下载网址：
http://openvpn.se/files/install_packages/openvpn-2.0.7-gui-1.0.3-install.exe

记得选上easy-rsa这部分脚本，安装完毕后，easy-rsa在C:\Program Files\OpenVPN\目录下。

把easy-rsa目录下的vars.bat.sample改名为vars.bat，并且修改其内容：
==================================
set KEY_COUNTRY=CN
set KEY_PROVINCE=Liaoning
set KEY_CITY=Shenyang
set KEY_ORG=OpenVPN
set KEY_EMAIL=elm@elm.freetcp.com
==================================
其它部分就不用修改了，上面部分修改成你自己的配置。

把easy-rsa下的openssl.cnf.sample改成openssl.cnf。

然后进入cmd.exe

输出: keys/ta.key
=========================================================================
C:\Program Files\OpenVPN\easy-rsa>openvpn --genkey --secret keys/ta.key

OK，那些keys就搞定了，下面开始写配置文件。
server01.ovpn内容：
----------------CUT Here-------------
port 1194
; proto tcp
proto udp
; dev tap
dev tun
;dev-node MyTap
ca ca.crt
cert server01.crt
key server01.key  # This file should be kept secret

persist-tun
status status.log
;log         /var/log/openvpn.log
;log-append  /var/log/TCP_openvpn.log

;mute 20
----------------CUT Here-------------
把配置文件放到C:\Program Files\OpenVPN\config\目录下。
把easy-rsa\keys\下的 ca.crt server01.crt server01.key ta.key dh1024.pem
复制到server01.ovpn所在目录。

同时下载本人写的破烂验证程序(checkpsw.exe)[不要仍砖块]放到OpenVPN配置目录下
程序在Windows XP SP2下测试通过，其他系统如果有问题，可以用源文件进行编译
程序在压缩包里面：

文件: checkpsw.rar 大小: 9KB 下载: 下载

在checkpsw.exe目录下建立password.txt[用于存放用户名&密码]文件：
password.txt文件格式：
用户名           密码            是否活动(0/1) 中间用空格隔开
Username     Password    Active
-------------Cut Here---------------------
wzk         wzk         1
-------------Cut Here---------------------



Server的配置已经结束，可以启动Server了，在右下角OpenVPN-gui上点右键，然后选择connected。
需要服务器启动后自动运行，修改 "控制面板" 下面的 "管理工具" 下的 "服务" 把OpenVPN设置成自动启动。

Client的配置文件：
client.ovpn
-------------Cut Here---------------------
client
dev tun
proto udp

remote 61.1.1.2 1194
;remote my-server-2 1194

;remote-random

resolv-retry infinite
nobind
user nobody
group nobody
route 192.168.0.0 255.255.252.0
persist-key
persist-tun

;http-proxy-retry # retry on connection failures
;http-proxy [proxy server] [proxy port #]

ca ca.crt
auth-user-pass

ns-cert-type server
tls-auth ta.key 1
comp-lzo
# Set log file verbosity.
verb 4
--------------Cut Here---------------------
并且把easy-rsa/keys下的ca.crt ta.key一起放到Client的
<OPENVPN_HOME>\config目录下。

Client的配置已经结束，可以连接Server了，在右下角OpenVPN-gui上点右键，然后选择connected。


OK，整个配置就完成了。
