Open. VPN 安装、配置客户端和服务端,以及Open. VPN的使用 (Windows 平台) - CSDN博客Open. VPN 开源,好用,而且免费,感谢 Open. VPN 团队开发此产品。简介Open. VPN允许参与创建VPN的单点使用公开密钥、电子证书、或者用户名/密码来进行身份验证。它大量使用了Open. SSL加密库中的SSLv. 3/TLSv. Open. VPN能在Solaris、Linux、Open. BSD、Free. BSD、Net. BSD、Mac. 2. 00. 0/XP/Vista/Windows. Android上运行,并包含了许多安全性的功能。它并不是一个基于Web的VPN软件,也不与IPsec及其他VPN软件包兼容。加密Open. VPN使用Open. SSL库加密数据与控制信息:它使用了Open. SSL的加密以及验证功能,意味着,它能够使用任何Open. SSL支持的算法。它提供了可选的数据包HMAC功能以提高连接的安全性。此外,Open. SSL的硬件加速也能提高它的性能。验证Open. VPN提供了多种身份验证方式,用以确认参与连接双方的身份,包括:预享私钥,第三方证书以及用户名/密码组合。预享密钥最为简单,但同时它只能用于创建点对点的VPN;基于PKI的第三方证书提供了最完善的功能,但是需要额外的精力去维护一个PKI证书体系。Open. VPN2. 0后引入了用户名/口令组合的身份验证方式,它可以省略客户端证书,但是仍有一份服务器证书需要被用作加密。网络Open. OpenVPN is a VPN program that uses SSL/TLS to create secure, encrypted VPN connections, to route your internet traffic, thus preventing snooping.

VPN连接能通过大多数的代理服务器,并且能够在NAT的环境中很好地工作。服务端具有向客户端“推送”某些网络配置信息的功能,这些信息包括:IP地址、路由设置等。Open. VPN提供了两种虚拟网络接口:通用Tun/Tap驱动,通过它们,可以创建三层IP隧道,或者虚拟二层以太网,后者可以传送任何类型的二层以太网络数据。传送的数据可通过LZO算法压缩。IANA(Internet. Assigned Numbers Authority)指定给Open. VPN的官方端口为1. 19. 4。Open. VPN 2. 0以后版本每个进程可以同时管理数个并发的隧道。Open. VPN使用通用网络协议(TCP与UDP)的特点使它成为IPsec等协议的理想替代,尤其是在ISP(Internet. VPN协议的情况下。安全Open. VPN与生俱来便具备了许多安全特性:它在用户空间运行,无须对内核及网络协议栈作修改;初始完毕后以chroot方式运行,放弃root权限;使用mlockall以防止敏感数据交换到磁盘。Open. VPN通过PKCS#1. 1支持硬件加密标识,如智能卡。以上关于 Open. VPN 的内容转载自维基百科申明:此文与免流无关,以免流为目的读者请离开。若想了解 Free. BSD 下 Open. VPN 的资讯可以访问 http: //blog. Open. VPN 的资料在 http: //blog. Open. VPN官网的问题,而是中囯症腐对其进行了封锁(这导致Google和其他很多网站也存在类似问题),因为Open. VPN的加密通讯功能再配合一台NAT主机,可以绕开GFW(很恶心东西,一个打着以网络安全为幌子的内向防火墙,用于阻碍中囯居民(中囯没有公民)对境外网络的完全访问)。——坦荡不需要遮掩,除非心里揣着脏东西!另注:目前 Open. VPN 常用的证书验证方式已经被 GFW 攻破,原因是网络通讯动态加密协议都存在一个特征,就是通讯协议初期握手时,IP包特定位置会发送一段明文,而能避免这个明文的出现的就是采用静态验证模式,可以突破. GFW 对 Open. VPN 的围攻。言归正传,Open. VPN 使用比较简单,流程上稍微注意一下,你一定可以很好的操作它,本文仅以证书及 key 作为验证方式对 Open. VPN 的使用进行介绍,有问题Q群里交流(群号在文章中)。连接模式大致如图所示 Open. VPN 可以为1对1或者1对多,甚至多对多的分散计算机构筑安全的互联网络,简单的说,就是通过物理网卡的连接,创建虚拟网络,借由虚拟网卡访问虚拟网络,形成一个跨越广域网的虚拟局域网。 相互间的通讯经严格加密,安全可靠,比如远程管理服务器,但又当心3. FTP之类的端口被那些草根黑客用字典猜密码,复杂的密码虽然不大可能猜中,但也实在很烦,但真正的黑客我还是很敬仰他们的,那么言归正传。管理这类服务器通过. Open. VPN 的证书认证连接成功后,你和服务器之间如同局域网,对内网再开放端口会安全的多,维护也较容易,防火墙对外网,则只针对例如8. Open. VPN 端口(可以自定,默认是1. Q群共享文件下载)Open. VPN 2. Open.

VPN\easy- rsa 目录,我们需要创建服务端和客户端证书。进入cmd前可能需要将C: \Program Files\Open. VPN\bin添加到环境变量的path中。Open. VPN 经测试,能运行于3. 2位和6. Windows 7下安装的话,必须以管理员权限运行。旧版本 Open. VPN 很可能在 Windows 8 运行不正常,其他旧版 Windows 3.

DHCP Client 服务打开,客户端需要通过这个服务接收服务端分配的 IP。打开操作系统自带的 DHCP Client 服务(管理工具的服务,但通常是自动),用于获取被分配的IP地址。部署完毕后,服务端运行 Open. VPN GUI,右键选择 server 再选择connect,激活服务端连接。注意看日志,或者 控制台运行openvpn - -config server 也可以,日志将详细显示连接情况,若有问题很容易排查,全部调试通过后建议以自动启动的服务的方式运行(服务内已经被安装了Open. VPN的一项,默认手动),这样不登入桌面也可以使用VPN。客户端运行 Open. VPN GUI,右键选择 client. Open. VPN,不需要Open. VPN GUI,这样使用更方便。至此 Open. VPN 连接完成。至于看不明白是为什么的,照葫芦画瓢走一两道,应该就明白了。有一点注意,若需要更新证书,自己又处于远程位置,则在服务端控制台将证书全部生成后,先把客户端证书下载好(但不部署),接着部署服务端证书,然后重新启动. Open. VPN 的服务端的服务(这时VPN中断),再将下载好的客户端证书部署好,并重新连接,即完成全部证书更新,不过整个过程需特别谨慎,不能有差错,否则可能被关在服务器外面,或者先把3. UDP协议(UDP要比TCP节省资源),不过据我个人测试下来,TCP连接在意外中断后自动重连接速度更快一些,但UDP协议兼容性更高;客户端和服务端的配置文件还有一些其他属性,各位可以参考备注或者下面留的链接。通过配置文件的 client to client 开关,还能将互联网上的多台终端集合到一个虚拟的局域网中,实现相互访问。主要参考资料 来自. Open.

Open. VPN is a full- featured SSL VPN which implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or username/password credentials. VPN virtual interface. Open. VPN is not a web application proxy and does not operate through a web browser. Open. VPN 2. 0 expands on the capabilities of. Open. VPN 1. x by offering a scalable client/server mode, allowing multiple clients to connect to a single Open. VPN server process over a single TCP or UDP port. Open. VPN 2. 3 includesa. IPv. 6 support and Polar. SSL support. This document provides step- by- step instructions for configuring an Open. VPN 2. x client/server VPN, including: The impatient may wish to jump straight to the sample configuration files: Intended Audience. This HOWTO assumes that readers possess a prior understanding of basic networking concepts such as IP addresses, DNS names, netmasks, subnets, IP routing, routers, network interfaces, LANs, gateways, and firewall rules.

VPN 1. x HOWTO is still available, and remains relevant for point- to- point or static- key configurations. Open. VPN Articles. For additional documentation, see the. Open. VPN wiki. Open. VPN Quickstart. While this HOWTO will guide you in setting up a scalable client/server VPN using an X5. PKI (public key infrastruction using certificates and private keys), this might be overkill if you are only looking for a simple VPN setup with a server that can handle. If you would like to get a VPN running quickly with minimal configuration, you might check out the. Static Key Mini- HOWTO. Static Key advantages. Simple Setup. No X5. PKI (Public Key Infrastructure) to maintain. Static Key disadvantages. Limited scalability - - one client, one server.

VPN wiki for details. For security, it's a good idea to check the. The Open. VPN executable should be installed on both server and client machines, since the single executable provides both client and server functions. Linux Notes (using RPM package)If you are using a Linux distribution which supports RPM packages (Su. SE, Fedora, Redhat, etc.), it's best to install using this mechanism. The easiest method is to find an existing binary RPM file for your distribution. You can also build your own binary. RPM file: rpmbuild - tb openvpn- [version]. Once you have the . Uvh openvpn- [details]. Installing Open.

One HTTP transaction can be poisoned by one or multiple poisons, and those poisons can be also configured to infect both global or route level traffic.
