1、如何在Windows环境下安装并配置OpenVPN
Step 1 OpenVPN安装配置
1.1 下载openvpn 并安装
· 下载openvpn-2.0.5-gui-1.0.3版,地址 http://openvpn.se/files/install_packages/openvpn-2.0.5-gui-1.0.3-install.exe,安装。(例如:安装到F:\OPENVPN目录下,下文举例都用此目录)
· 安装完成后生成一个新网卡,并在网络连接里出现本地连接[X],把tcp/ip属性改成手动配置,192.168.10.1(根据实际情况更改) ,255.255.255.0,其余不填。
1.2 生成证书
· 修改F:\OpenVPN\easy-rsa\vars.bat.sample的以下部分
CODE:
set HOME=%ProgramFiles%\OpenVPN\easy-rsa
set KEY_COUNTRY=US
set KEY_PROVINCE=CA
set KEY_CITY=SanFrancisco
set KEY_ORG=FortFunston
set [email protected]
(请根据自身情况修改)改为
CODE:
set HOME=F:\OpenVPN\easy-rsa
set KEY_COUNTRY=CN
set KEY_PROVINCE=Hubei
set KEY_CITY=Wuhan
set KEY_ORG=51NB
set [email protected]
· 生成证书
o OpenVPN 有两种安全模式,一种基于使用 RSA 证书和密钥的 SSL/TLS,一种使用预先分享的静态密钥。本文采用SSL/TLS 模式。TLS模式的优点是安全,而且便于管理用户。默认情况下证书和用户是一对一的,多个用户使用同一证书会被踢出。

生成多个客户端密钥,执行build-key client1 …… build-key xyz。
复制证书文件
刚才生成的证书文件在F:\OpenVPN\easy-rsa\keys下,服务器端需要的文件为ca.crt,dh1024.pem,server.crt,server.key ,客户端需要的文件为:ca.crt client.crt client.key(xxx.crt xxx.key),配置.ovpn文件时需要用到。
1.3 配置server.ovpn文件
· 在\OpenVPN\config目录下创建server.ovpn文件将ca.crt,dh1024.pem,server.crt,server.key复制到F:\OpenVPN\config目录下
· 服务器端文件示例:
server.ovpn
CODE:
port 1198
proto tcp-server
dev tun
server 192.168.10.0 255.255.255.0
keepalive 20 180
ca ca.crt
cert server.crt
key server.key
dh dh1024.pem
push "redirect-gateway def1"
push "dhcp-option DNS 192.168.10.1"
mode server
tls-server
status openvpn-status.log

1.4 客户端安装与配置
o 安装OpenVPN,同1.1,但是不用更改本地连接设置。
o 配置OpenVPN
§ 在\OpenVPN\config目录下创建client.ovpn文件,将ca.crt client.crt client.key 复制到 \OpenVPN\config
目录下,这3个文件由服务器端生成并发放。
§ 客户端文件示例:
client.ovpn
CODE:
client
dev tun
proto tcp-client
remote jacky.10dig.com 1198 #这里填入remote server add,可用IP或者域名,
#若Server是动态IP,可到http://www.wingdns.com/注册动态域名绑定动态IP。
#如Client所连接Server使用路由上网,则需要使用NAT将地址映射到Server端。
resolv-retry infinite
nobind
http-proxy 10.0.0.172 80 #这里填入你的代理服务器地址和端口,没有代理则不用这行
mute-replay-warnings
ca ca.crt
cert client.crt #这里改成每个客户端相应的证书
key client.key #这里改成每个客户端相应的证书
comp-lzo
verb 4
status openvpn-status.log
右击openvpn-gui图标,点connect,即可连接。

3、PPTP和OpenVPN有什么区别?
PPTP点对点隧道协议(PPTP)是一种实现虚拟专用网络的方法。 PPTP使用用于封装PPP数据包的TCP及GRE隧道控制通道。
OpenVPNOpenVPN是一免费开源软件,以路由器或桥接配置和远程访问设备方式实现虚拟专用网络(VPN)创建安全的点对点或站对站连接的解决方案。它使用SSL / TLS安全加密,具有穿越网络地址转换(NATs)和防火墙的功能。
在PPTP和OpenVPN二者之间做出选择的一个重要考虑因素,也是我们无法控制的因素,就是有时互联网服务供应商会阻止PPTP连接。次情况下我们无计可施,只能选择使用OpenVPN。 PPTP具有一些独特优势,但此刻用OpenVPN会是不错的选择。
PPTP可以应用到几乎所有的操作系统软件,无需安装任何软件。它也兼容许多移动设备,如iphone,ipad和Windows移动,安装简易。相比之下,OpenVPN的安装比PPTP要复杂一点,但只要按照正确的指示安装则无太大困难。请注意OpenVPN不兼容移动设备。
PPTP加密技术使用密码作为密钥,它的数据流载有可获取的混编密码。如果中间有人拦截到了数据流并且破译了密码(尽管可能但很难),那么他就可以破译你的信息。然而OpenVPN使用非常强大的加密(Blowfish)技术。即使有人拦截你的数据流,他们也无计可施。这使得OpenVPN比PPTP安全得多。
选择如果你希望得到高安全性以及更加关注数据安全传输问题,那么你应该使用OpenVPN。如果您为了简便或者想在移动设备上使用VPN那么PPTP适合你。还有其他协议,例如L2P或IPSec,但他们在用户友好或成本上没有优势。

5、如何使用OpenVPN和PrivacyIDEA搭建双因素认证的远程接入
第一种,使用PAM的privacyidea_pam.py模块。OpneVPN使用PAM认证,PAM调用privacyidea_pam.py模块和PrivacyIDEA做验证。
第二种,直接集成OpenVPN和FreeRADIUS。OpenVPN使用radius认证,FreeRADIUS向PrivacyIDEA验证。
第三种,在OpenVPN中使用RADIUS的PAM模块。
6、Windows 7上OpenVPN怎么设置使用
从问题来看只是安装了OpenVPN,但是没有对其进行配置。此外OpenVPN分服务器端和客户端(安装程序一样,只是配置文件不一样)。
OpenVPN客户端不是安装了就能用,需要服务器端才能起作用。比如OpenVPN客户端装在Windows 7笔记本上,服务器端用的是Windows2003 VPS。
需要进行的操作为:
(1)对服务器端进行设置
(2)在服务器端并生成相应的文件(包括server.ovpn, ca.crt, client.key, client.crt),确保配置正确后启动服务器端。
(3)复制客户端需要的文件(ca.crt, client.key, client.crt)到客户端,制作client.ovpn,启动客户端连接服务器端。
