[原创]用OpenVPN构建安全VPN [OpenVPN + CA]
一直想写一片关于VPN配置方面的文章，由于时间等等很多问题，一直没有落实，现在终于和大家见面了，由于本人知识有限也并非专业从事这方面工作的，难免有错误，望指正，共同提高。
自从认识VPN以来，一直在找寻一个容易配置、功能强大、支持多系统的VPN程序，由于一直没有找到合适的软件，Linux下的FreeSWAN、OpenBSD FreeBSD下的IPSec、Windows下的PPTP都试了试，始终不能满足自己的要求，直到OpenVPN的出现。
关于各种VPN软件或者硬件的优缺点，在这里我就不再叙述了，因为这个掺杂着很多人为的因素在里边（萝卜好吃还是青菜好吃？），一个软件：稳定、符合自己的要求、自己用的习惯就是一个好软件。
对于OpenVPN，在CU的VPN版面也有过很多的讨论，其中也不乏精华的文章，但是都是使用Static key验证的，从字面上就可以看出来Static key使用的就是预先生成的key对数据进行加密和解密，也就是常说的对称试加密，加密和解密双方必须预先知道加密的Key。本文讨论的是基于TLS加密方式，使用CA验证VPN Client的身份，OpenVPN使用TLS加密是通过使用公开密钥（非对称密钥，加密解密使用不同的key，一个称为Public key，另一个是Private key）对数据进行加密的，对于TLS传输的工作原理，大家可以去Google一下，资料一大堆。对于OpenVPN使用TLS mode，首先Server和Client要有相同CA签发的证书，双方通过交换证书验证双方的合法性以决定是否建立VPN连接，然后使用对方CA把自己目前使用的数据加密方法（类似于密钥）加密后发送给对方，由于使用对方CA加密的，所以只有对方CA对应的Private key才能解密该字串，保证了此密钥的安全性，并且此密钥定期改变，对于窃听者来说，可能还没有破解出密钥，通信双方已经更换密钥了。
我个人对OpenVPN的感觉（或者说是我使用OpenVPN的理由），NAT穿透力特强，支持HTTP代理，对动态地址支持很好，可配置性强，配置安全，开源便于二次开发...其他没有想好：）。
关于OpenVPN的相关内容可以在http://openvpn.net上找到。
下面开始正式讨论OpenVPN的安装和配置方法，本文是在Fedora Core 2环境下配置的，由于机器在网络中不是在网关的位置，所以使用NAT方式来访问内网，否则还涉及到配置网络设备的路由。假设我的VPN Server有2块网卡，eth0对外，IP：61.1.1.2 eth1对内，IP：192.168.1.2，内网地址：192.168.0.0/16
本文除配置文件中行首的"#"是注释外，其他行首的"#"都是提示符，如果在非配置文件一行中第二次出现"#"说明后面的是注释，书写命令时可以省略。
获取并安装Openvpn：
首先检查系统是否安装lzo实时压缩工具
$rpm -qa | grep lzo
如果没有安装可以在http://www.oberhumer.com/opensource/lzo/找到并安装，安装方法详见压缩包中的INSTALL文件，当然也可以用rpm包安装，记住一定要安装lzo-devel开头的那个包，因为OpenVPN需要使用lzo的头文件。
$wget http://mesh.dl.sourceforge.net/sourceforge/openvpn/openvpn-2.0_rc16.tar.gz
$tar -zxvf openvpn-2.0_rc16.tar.gz
$cd openvpn-2.0_rc16
$./configure
$make
$su
#make install
按照INSTALL文件中的说明，做如下操作：
#mknod /dev/net/tun c 10 200 #创建一个tun设备
#echo "alias char-major-10-200 tun" >;>; /etc/modprobe.conf
#echo 1 >; /proc/sys/net/ipv4/ip_forward #打开系统的转发功能
接下来就生成服务器客户端需要使用的keys了，为了方便，我们使用OpenVPN包自带的脚本生成。
#mkdir /etc/openvpn
#cp -r easy-rsa /etc/openvpn #切换到OpenVPN源代码目录执行
修改vars 文件

# don't edit this file in place in

把server.conf文件保存到/etc/opennvpn目录中，并把使用easy-rsa下的脚本什成的key都复制到/etc/openvpn目录下，命令如下:
#cd /etc/openvpn
#cp easy-rsa/keys/ca.crt .
#cp easy-rsa/keys/server.crt .
#cp easy-rsa/keys/server.key .
#cp easy-rsa/keys/dh1024.pem .
#cp easy-rsa/keys/ta.key .
#cp easy-rsa/keys/vpncrl.pem .
创建OpenVPN启动脚本，可以在源代码目录中找到，在sample-scripts目录下的openvpn.init文件，将其复制到/etc/init.d/目录中，改名为openvpn
然后运行：
#chkconfig --add openvpn
#chkconfig openvpn on
立即启动openenvpn
#/etc/init.d/openvpn start
接下来配置客户端的配置文件client.conf：
Linux或Unix下使用扩展名为.conf Windows下使用的是.ovpn,并把需要使用的keys复制到配置文件所在目录ca.crt elm.crt elm.key ta.key
-------------Cut Here---------------------
# 申明我们是一个client，配置从server端pull过来，如IP地址，路由信息之类“Server使用push指令push过来的”
client
#指定接口的类型，严格和Server端一致

;dev tun
# Windows needs the TAP-Win32 adapter name
# from the Network Connections panel
# if you have more than one. On XP SP2,
# you may need to disable the firewall
# for the TAP adapter.
;dev-node MyTap
# 使用的协议，与Server严格一致
;proto tcp
proto udp
#设置Server的IP地址和端口，如果有多台机器做负载均衡，可以多次出现remote关键字
remote 61.1.1.2 1194
;remote my-server-2 1194
# 随机选择一个Server连接，否则按照顺序从上到下依次连接
;remote-random
# 始终重新解析Server的IP地址（如果remote后面跟的是域名），
# 保证Server IP地址是动态的使用DDNS动态更新DNS后，Client在自动重新连接时重新解析Server的IP地址
# 这样无需人为重新启动，即可重新接入VPN
resolv-retry infinite
# 在本机不邦定任何端口监听incoming数据，Client无需此操作，除非一对一的VPN有必要
nobind
# 运行openvpn用户的身份，旧版本在win下需要把这两行注释掉，新版本无需此操作
user nobody
group nobody
#在Client端增加路由，使得所有访问内网的流量都经过VPN出去
#当然也可以在Server的配置文件里头设置，Server配置里头使用的命令是
# push "route 192.168.0.0 255.255.255.0"
route 192.168.0.0 255.255.0.0
# 和Server配置上的功能一样 如果使用了chroot或者su功能，最好打开下面2个选项，防止重新启动后找不到keys文件，或者nobody用户没有权限启动tun设备
persist-key
persist-tun
# 如果你使用HTTP代理连接VPN Server，把Proxy的IP地址和端口写到下面
# 如果代理需要验证，使用http-proxy server port [authfile] [auth-method]
# 其中authfile是一个2行的文本文件，用户名和密码各占一行，auth-method可以省略，详细信息查看Manual
;http-proxy-retry # retry on connection failures
;http-proxy [proxy server] [proxy port #]
# 对于无线设备使用VPN的配置，看看就明白了
# Wireless networks often produce a lot
# of duplicate packets. Set this flag
# to silence duplicate packet warnings.
;mute-replay-warnings
# Root CA 文件的文件名，用于验证Server CA证书合法性，通过easy-rsa/build-ca生成的ca.crt，和Server配置里的ca.crt是同一个文件
ca ca.crt
# easy-rsa/build-key生成的key pair文件，上面生成key部分中有提到，不同客户使用不同的keys修改以下两行配置并使用他们的keys即可。
cert elm.crt
key elm.key
# Server使用build-key-server脚本什成的，在x509 v3扩展中加入了ns-cert-type选项
# 防止VPN client使用他们的keys ＋ DNS hack欺骗vpn client连接他们假冒的VPN Server
# 因为他们的CA里没有这个扩展
ns-cert-type server
# 和Server配置里一致，ta.key也一致，注意最后参数使用的是1
tls-auth ta.key 1
# 压缩选项，和Server严格一致
comp-lzo
# Set log file verbosity.

--------------Cut Here---------------------
Linux下Client的OpenVPN的安装方法一样，只是配置文件和keys上的不同，只要把client.conf ca.crt elm.crt elm.key ta.key复制到/etc/openvpn目录即可启动VPN。
Win下OpenVPN的安装，WIN下有图形界面的OpenVPN-GUI程序，下载地址http://openvpn.se
下载安装，默认下一步就OK了，安装完事后在托盘上出现一个新的图标，把client.ovpn ca.crt elm.crt elm.key ta.key文件拷贝到C:\Program Files\openvpn\config目录下，然后点右键connect就OK了。
对于LinuxServer使用NAT的一些说明：
首先要把系统的Forward打开，可以通过如下命令实现
echo 1 >; /proc/sys/net/ipv4/ip_forward
或者使用
sysctl -w net.ipv4.ip_forward=1
或者修改/etc/sysctl.conf文件，增加
net.ipv4.ip_forward = 1
设定SNAT的规则，使用iptables命令
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth1 -j SNAT --to-source 192.168.1.2
OK,OpenVPN Client可以访问内网了。
由于是第一次写这么详细的文档，有很多地方写的不详细，有很多东西可能我认为是很容易理解的，但是可能没有从一个初学者的角度去考虑问题，还希望大家多提意见，以便改进，由于本人不是专业从事VPN的研究，本文难免有错误之处，还往指正。
国外很多软件都有Howto，但是OpenVPN没有Howto，希望大家能在本文＋其他static key的文章上，形成一个不是很全面的HOWTO。

Server使用的配置文件server.conf
请问
server.conf放在那？/etc/openvpn/easy-rsa/server.conf
还是/etc/openvpn

--------------Cut Here-----------------
把server.conf文件保存到/etc/opennvpn目录中，并把使用easy-rsa下的脚本什成的key都复制到/etc/openvpn目录下，命令如下:
#cd /etc/openvpn

server后面写的IP地址是你VPN接入后的使用的IP地址
记得在看OpenVPN的文档的时候，有一个人用一句非常形象的话说了一下VPN是什么样的东西，一根很长的、且安全的电缆从你的机器连接到VPN对端机器。
对于这对电缆两端的网卡也必需有地址，server后面的地址就是为这些“网卡”用的

在server模式下工作，只要openvpn启动起来了，网卡就起来了
tap0网卡的所有数据是通过VPN那个通道出去的，如果你的VPN连接没有成功，你设置网卡的IP地址是没有用的
CA是用来验证身份和加密传输的，如果你的CA和keys不对，VPN没有办法连接成功，VPN通道不能建立

经检查确认，是你现在那台server 1.72生成的证书和签发的证书有点问题，传到别的机器上用openssl verify -CAfile ca.crt elm.crt出错
换其他机器生成证书就OK了：）
good，luck
由于你在server的配置文件上写了
push "redirect-gateway"
所以连接上后把你原有的网关都给删除了
现在那两台机器已经无法访问了

证书CA完全按照http://www.linuxaid.com.cn/forum/showdoc.jsp?l=1&i=85071所做,唯一不同的是我用的是RH9.0,而lzo用的是：lzo-1.08-3.1.fc2.dag.i386.rpm,可是出现奇怪问题。
在LAN内有两台XP其中一台能正常连接到服务器,一切工作正常，另一台则连接不成功,出现上面的错误日志。两台客户端的配置文件和CA完全一样.
请斑竹帮忙看看问题出在哪里。
谢谢~~~~~~~~~~~~~~~~

请问两台机器是否使用相同的keys？
正常来说是不太可能这样的
gouya 回复于：2005-03-10 19:09:25
刚开始使用相同的KEYS,后来换做不同的KEYS了也不行........
奇怪的是.....这台机器能上LAN内的一台OPENVPNSERVER(CA.CRT等文件都换为LAN内VPNSERVER的),一点问题也没有,可就是不能上外网的那个。...
郁闷中.......
怎么才能吊销一个KEYS呢?
wenzk 回复于：2005-03-10 19:51:08
ca.crt在双方的机器上应该是一样的
在keys目录下有01.pem 02.pem ......等等文件，如果哪个证书需要吊销
直接./revoke-crt xx.pem即可，xx是被吊销正的的serial number
然后使用make-crl生成吊销证书的列表

感谢楼主的支持。。。。。。。。。。
我的问题基本上解决了。。。今天晚上换了个服务器，还是出现问题。
后来有重新安装了以下2000系统。。。。问题仍旧出现，无奈之下换个个硬盘，重新安装2000，结果好用了。。。。。这是又把，原来的硬盘接回来，就是刚才死活连接不上的那个2000系统，结果竟然也可以连上了。。。。我晕死了。。。。。。呵呵~~~~~~~~~~说的都没人相信。可事实就是这样的。
在次请教你个问题：
1、能不能在将客户端去往服务器端的广播包屏蔽掉。
2、能不能对客户端静态的分配IP地址。
3、一个KEYS原则上是不上只能，有一个客户端连接，能不能有多个连接。
谢谢~~~~~~~~~~同志们。

1 不知道怎么搞
2 相对固定的，下次重新连接IP也固定了，修改配置文件，客户可以指定IP地址的
3 把duplicate-cn打开就可以了
