当时在安装 Open××× 的时候，得到了 WenZK 的指导帮助。在此表示感谢。 一. Open××× 安装环境 Server 端的环境 redhat, kernel版本: 2.4.20-31.9, IP 为 70.8.7.6 kernel 需要支持 tun 设备, 需要加载 iptables 模块. 检查 tun 是否安装: 代码: [email=root@a]root@a[/email] [/]# modinfo tun filename: /lib/modules/2.4.20-31.9/kernel/drivers/net/tun.o description: author: license: "GPL" 如果没有 modinfo 命令, 直接找一下, 看看 kernel 里是否有 tun.o 文件: 代码: find -name tun.o ./lib/modules/2.4.20/kernel/drivers/net/tun.o 检查iptables 模块, 查看是否有下列文件: /etc/init.d/iptables 安装的 Open××× 的版本: 2.0.5. 现在似乎已经有一个更新的版本了. 可在 上下载. Client 端的环境: Windows XP PRO SP2 Open××× GUI For windows 1.0.3 , 可在 open***.se 下载 注意: Open××× GUI for windows 的版本要和 Open××× Server 的版本配套. 例如, 服务器装的是 Open××× 2.0.5, 那么下载的 Open××× GUI fow windows 应该是: open***-2.0.5-gui-1.0.3-install.exe Open××× GUI的所有历史版本: 二. Open××× 服务端安装过程 用 SecureCRT 登录到 host, 进入根目录 代码: cd / 下载 LZO，解压到lzo-2.02. 地址: 代码: wget 下载 Open×××, 解压到open***-2.0.5 地址: 代码: wget 安装 LZO 代码: cd /lzo-2.02 ./configure make make check make install 安装 Open××× 代码: cd /open***-2.0.5 ./configure
./configure --with-lzo-headers=/usr/local/include --with-lzo-lib=/usr/local/lib --with-ssl-headers=/usr/local/include/openssl --with-ssl-lib=/usr/local/lib
# 或用指定dir: (注:下述命令, 应该在一行写完. 为了方便显示, 这里分成了四行) # ./configure --with-lzo-headers=/usr/local/include # --with-lzo-lib=/usr/local/lib # --with-ssl-headers=/usr/local/include/openssl # --with-ssl-lib=/usr/local/lib make make install 生成证书Key 初始化 PKI (如果没有 export 命令也可以用 setenv [name] [value] 命令) 代码: cd /open***-2.0.5/easy-rsa export D=`pwd` export KEY_CONFIG=$D/openssl.cnf export KEY_DIR=$D/keys export KEY_SIZE=1024 export KEY_COUNTRY=CN export KEY_PROVINCE=GD export KEY_CITY=SZ export KEY_ORG="dvdmaster" export KEY_EMAIL="" Build: 代码: ./clean-all ./build-ca Generating a 1024 bit RSA private key ................++++++ ........++++++ writing new private key to 'ca.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request.

Open××× GUI For Windows 客户端安装过程 安装 Open××× GUI For Windows, 到 下载. 目前的版本是 1.0.3. 注意: Open××× GUI 的版本要和 Open××× Server 的版本配套. 详见第一节一. 安装环境中的说明. 依屏幕指示安装open*** gui. 配置 open*** gui 安装结束后, 进入安装文件夹下的 config 目录, 然后将上面第 10 步建立的 client.conf 文件从 server 上下载到此文件夹, 并更名为 client.o*** 同时, 将第8 步打包的 mykeys.tar 中的下列证书文件解压到此文件夹: 代码: ca.crt ca.key client1.crt client1.csr client1.key 然后双击 client.o*** 即可启动 open***, 或者通过 Open××× GUI 的控制启动 ×××. 如果双击 client.o*** 没有反应, 则在任务栏点 Open××× GUI 的小图标右键, 选择 edit config, 将内容复制过去再保存. 然后再点右键中的 connect即可. 如果需要第二台机器上使用 *** , 进行同样的配置, 只需要将 client1.crt, client1.csr, client1.key 换成对应的 client2.xxx 即可, 然后将 client.o*** 中的对应key文件值改掉. 四. Open××× 配置样例文件 Open××× 服务端：server.conf 代码: local 70.8.7.6 port 1194 proto udp dev tun ca /open***-2.0.5/easy-rsa/keys/ca.crt cert /open***-2.0.5/easy-rsa/keys/server.crt key /open***-2.0.5/easy-rsa/keys/server.key # This file should be kept secret dh /open***-2.0.5/easy-rsa/keys/dh1024.pem server 10.8.0.0 255.255.255.0 client-to-client keepalive 10 120 comp-lzo persist-key persist-tun status /open***-2.0.5/easy-rsa/keys/open***-status.log verb 4 push "dhcp-option DNS 10.8.0.1" push "dhcp-option DNS 70.88.98.10" # name server 地址, 如何获取见随后说明 push "dhcp-option DNS 70.88.99.11" # name server 地址, 如何获取见随后说明 说明: 有些 domain 被 GFW 封掉了, 这时, 如果要访问这些网站, 应该将 server 上的 dns push 到 client. 上面示例中的 dns ip: 70.88.98.10, 70.88.99.10, 可以在 /etc/resolv.conf 中找到: 代码: vi /etc/resolv.conf nameserver 70.88.98.10 nameserver 70.88.99.11 Open××× 客户端: client.o*** 代码: client dev tun proto udp remote 70.8.7.6 1194 persist-key persist-tun ca ca.crt cert client1.crt key client1.key ns-cert-type server comp-lzo verb 3 redirect-gateway def1 五. Open××× 访问外网的设置 打开路由 ×××连接成功后, 还需要设置路由, 才能透过×××访问Internet. 在 linux host 上添加路由: 代码: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j SNAT --to-source 70.8.7.6 /etc/init.d/iptables save /etc/init.d/iptables restart 不同的机器，-o eth0 参数可能不一样，具体可输入 ifconfig 查看，搞清 ip(70.8.7.6)所在的网卡号. 同时, 需要将 ip forward 打开. 不要用 echo 1 > /proc/sys/net/ipv4/ip_forward 的方式, 这种方式重启后无效. 先查看一下: 代码: sysctl -a | grep for #查看结果: net.ipv4.conf.tun0.mc_forwarding = 0 net.ipv4.conf.tun0.forwarding = 1 net.ipv4.conf.eth0.mc_forwarding = 0 net.ipv4.conf.eth0.forwarding = 1 net.ipv4.conf.lo.mc_forwarding = 0 net.ipv4.conf.lo.forwarding = 1 net.ipv4.conf.default.mc_forwarding = 0 net.ipv4.conf.default.forwarding = 1 net.ipv4.conf.all.mc_forwarding = 0 net.ipv4.conf.all.forwarding = 1 net.ipv4.ip_forward = 1 如果你的主机上列数值不是为1, 则要将其改成1, 例如: 代码: sysctl -w net.ipv4.ip_forward=1 依此类推. 开启域名服务器 如果你需要访问一些已经被GFW封掉了域名的网站, 但你的 Open××× 服务器没有被封的话，那么你需要在你的主机上开启 name server, 并将 dns push 给 client。 一般的独立主机, 都带有 private dns server. 代码: rpm -qa | grep bind /etc/init.d/named start 另外, 必须保证 server.conf 配置中, 有这三个配置: 代码: push "dhcp-option DNS 10.8.0.1" push "dhcp-option DNS 70.88.98.10" # name server 地址 push "dhcp-option DNS 70.88.99.11" # name server 地址 当 client 连接成功后, 在 cmd 下执行 ipconfig /all, 应该有这类似这样的输出: 代码: Ethernet adapter Local Area Connection 3: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : TAP-Win32 Adapter V8 Physical Address. . . . . . . . . : 00-FF-AA-B0-60-2B Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 10.8.0.6 Subnet Mask . . . . . . . . . . . : 255.255.255.252 Default Gateway . . . . . . . . . : 10.8.0.5 DHCP Server . . . . . . . . . . . : 10.8.0.5 DNS Servers . . . . . . . . . . . : 10.8.0.1 70.88.98.10 70.88.99.11 Lease Obtained. . . . . . . . . . : 2006年5月25日 5:13:52 Lease Expires . . . . . . . . . . : 2007年5月25日 5:13:52 六. 设置 Open××× 服务器 reboot后自动启动 open*** 执行命令: 代码: vi /etc/rc.local 然后在最后面加入此行: 代码: /usr/local/sbin/open*** --config /usr/local/etc/server.conf > /dev/null 2>&1 & 七. Open××× 测试 你可以用 ××× 登录上去之后, 测试 MSN, QQ, IE 等网络应用, 也可以尝试访问一些被 GFW 禁掉的网站, 当然, 前提是你的 ××× 服务器不在境内. 八. 使用 Open××× 的强烈注意事项 不建议用 ××× 登录 paypal 帐户和 google adsense 帐户. 否则有可能导致帐户受限或带来其他风险.
