利用libreswan+V2Ray实现科学上网

实验背景​

在云主机中(阿里云、腾讯云等)，大陆地区的机器是无法科学上网的，并且好多优秀的网站、工具等无法访问或者下载速度很慢，例如下载github上的一些资源，我们可以购买VPS(例如Vultr)或者香港等地区的主机，再配合一些软件就可以实现科学上网了

我们可以使用 libreswan 搭建 ipssec 隧道实现不通地域主机内网互通，然后使用 V2Ray 作为代理工具实现科学上网

1.安装配置libreswan​

1.0 编辑环境变量文件​

北京、香港区服务器操做

# 编辑文件
cat > /opt/wall_env << EOF
BJ_PUBLIC_IP=81.70.22.232
BJ_PRIVATE_IP=172.31.0.3
BJ_IP_SUBNET=172.31.0.0/24
HK_PUBLIC_IP=129.226.167.89
HK_PRIVATE_IP=10.0.0.17
HK_IP_SUBNET=10.0.0.0/24
EOF

# 加载环境变量
source /opt/wall_env

1.1 安装依赖包​

北京、香港区服务器操做

yum -y install audit-libs-devel bison curl-devel fipscheck-devel flex gcc ldns-devel libcap-ng-devel libevent-devel libseccomp-devel libselinux-devel make nspr-devel nss-devel pam-devel pkgconfig systemd-devel unbound-devel xmlto

1.2 安装libreswan​

北京、香港区服务器操做

yum -y install libreswan

1.3 配置内核参数​

北京、香港区服务器操做

# 开启路由转发
sed -i '/^net.ipv4.ip_forward/d' /etc/sysctl.conf 
cat >> /etc/sysctl.conf << EOF
net.ipv4.ip_forward = 1
EOF

# 使配置生效
sysctl -p

1.4 启动ipsec​

systemctl start ipsec && systemctl enable ipsec

查看状态

1.5 防火墙配置​

香港区服务器操作

防火墙策略开放 udp 500 和 udp 4500 端口，允许北京区主机公网IP访问

1.6 验证端口连通性​

北京区服务器操作

$ nmap -sU 2.2.2.2 -p 500,4500 -Pn

Starting Nmap 6.40 ( http://nmap.org ) at 2022-03-20 21:32 CST
Nmap scan report for 2.2.2.2
Host is up.
PORT     STATE         SERVICE
500/udp  open|filtered isakmp
4500/udp open|filtered nat-t-ike

Nmap done: 1 IP address (1 host up) scanned in 3.17 seconds

1.7 配置预共享密钥​

北京、香港区服务器操做

/etc/ipsec.secrets 配置文件中有 include /etc/ipsec.d/*.secrets ，因此我们在 /etc/ipsec.d 目录下新建 *.secrets 文件

$ cat /etc/ipsec.secrets
include /etc/ipsec.d/*.secrets

新建 /etc/ipsec.d/vm.secrets

cat > /etc/ipsec.d/vm.secrets << EOF
# 源ip 目的ip : PSK "key"
0.0.0.0 0.0.0.0 : PSK "baidu666com"
EOF

1.8 配置ipsec连接​

/etc/ipsec.conf 配置文件中有 include /etc/ipsec.d/*.conf ，因此我们在 /etc/ipsec.d 目录下新建 *.conf 文件，同时 /etc/ipsec.conf 文件中有详细的示例说明

1.8.1 配置香港区服务器​

Libreswan 不使用术语 source 或 destination。相反，它用术语 left 和 right来代指终端（主机）。虽然大多数管理员用 left 表示本地主机，right 表示远程主机，但是这样可以在大多数情况下在两个终端上使用相同的配置。 由于我们的服务器使用的是vpc网络，采用静态nat的形式，在配置 left 和 right 时，本端的ip需要使用内网ip或 %defaultroute。left 和 right 是两端的ip地址，而 leftid 和 rightid 为代号id。 这里我们指定北京区为 left  、香港区为 right

cat > /etc/ipsec.d/vm.conf << EOF
conn bj-vm-hk
        authby=secret # 指定认证类型预共享秘钥
        ike=3des-sha1 # 指定ike算法为3des-sha1
        keyexchange=ike # 指定ike
        phase2=esp
        phase2alg=3des-sha1
        compress=no # 指定是否压缩
        pfs=yes # 指定是否加密
        auto=start # 指定连接添加类型。start为开机自启，add为添加不主动连接
        type=tunnel # 指定模式类型为隧道模式|传输模式
        
        left=%any # 允许哪些IP可以访问！！！
        leftsubnets={$BJ_IP_SUBNET} # 北京区主机内网IP段
        leftid=%any
        leftnexthop=%defaultroute
        
        right=$HK_PRIVATE_IP # 这里要指定香港区主机内网IP
        rightsubnets={$HK_IP_SUBNET} # 这里要指定香港区主机内网IP段
        rightid=%any # 经验证，这里只能写%any、公网IP、@east或@west
        rightnexthop=%defaultroute
EOF

1.8.2 配置北京区服务器​

Libreswan 不使用术语 source 或 destination。相反，它用术语 left 和 right来代指终端（主机）。虽然大多数管理员用 left 表示本地主机，right 表示远程主机，但是这样可以在大多数情况下在两个终端上使用相同的配置。 由于我们的服务器使用的是vpc网络，采用静态nat的形式，在配置 left 和 right 时，本端的ip需要使用内网ip或 %defaultroute。left 和 right 是两端的ip地址，而 leftid 和 rightid 为代号id。 这里我们指定香港区为本端机器，北京区为对端机器，即香港区为 left 、 北京区为 right

cat > /etc/ipsec.d/vm.conf << EOF
conn bj-vm-hk
        authby=secret # 指定认证类型预共享秘钥
        ike=3des-sha1 # 指定ike算法为3des-sha1
        keyexchange=ike # 指定ike
        phase2=esp
        phase2alg=3des-sha1
        compress=no # 指定是否压缩
        pfs=yes # 指定是否加密
        auto=start # 指定连接添加类型。start为开机自启，add为添加不主动连接
        type=tunnel # 指定模式类型为隧道模式|传输模式
        
        left=$BJ_PRIVATE_IP # 这里必须是北京区主机本机内网IP！！！
        leftsubnets={$BJ_IP_SUBNET} # 北京区主机内网IP段
        leftid=%any
        leftnexthop=%defaultroute
        
        right=$HK_PUBLIC_IP # 这里要指定香港区主机公网IP
        rightsubnets={$HK_IP_SUBNET} # 这里要指定香港区主机内网IP段
        rightid=%any # 经验证，这里只能写%any、公网IP、@east或@west
        rightnexthop=%defaultroute
EOF

1.8.3 开启ipsec日志​

北京、香港区服务器操做

这里需要编辑 /etc/ipsec.conf 把日志打开，默认日志路径为 /var/log/pluto.log

sed -i 's/#logfile=/logfile=/' /etc/ipsec.conf

1.8.4 重启ipsec​

北京、香港区服务器操做

systemctl restart ipsec

1.8.5 验证​

1.8.5.1 两端互ping​

北京区服务器ping香港区服务器

$ ping -c2 $HK_PRIVATE_IP

2.2 北京区服务器操作​

北京区服务器由于执行一键安装脚本太太太🐔8⃣️慢了，因此需要先下载安装脚本，然后通过加速地址下载v2ray安装包，最后执行本地安装

2.2.1 下载一键安装脚本​

wget https://raw/branch.githubusercontent.com/v2fly/fhs-install-v2ray/master/install-release.sh

2.2.2 下载安装包​

截止2022.3.23，v2ray最新稳定版本为4.44

由于 https://github.com/v2fly/v2ray-core/releases/download/v4.44.0/v2ray-linux-64.zip 下载太慢了，可以使用如下加速地址

wget https://download.fastgit.org/v2fly/v2ray-core/releases/download/v4.44.0/v2ray-linux-64.zip
或
wget https://ghproxy.com/https://github.com/v2fly/v2ray-core/releases/download/v4.44.0/v2ray-linux-64.zip

2.2.3 安装v2ray​

赋予脚本可执行权限

chmod +x install-release.sh

执行安装

./install-release.sh -l v2ray-linux-64.zip
