corplink-rs

使用 rust 实现的 飞连 客户端，支持 Linux/Windows10/MacOS

安装

ArchLinux

下载 release 中的安装包，并安装

pacman -U corplink-rs-4.1-1-x86_64.pkg.tar.zst

欢迎贡献其它包管理器的打包脚本

手动编译

linux/macos

git clone https://github.com/PinkD/corplink-rs --depth 1
cd corplink-rs
# build libwg
cd libwg
./build.sh
# if you are using Windows, you can clone and build libwg maunally
# ref: wireguard-go/Makefile:libwg

cargo build --release
# install corplink-rs to your PATH
mv target/release/corplink-rs /usr/bin/

windows

参考 #34

用法

该程序需要 root 权限来启动 wg-go (windows 上需要管理员权限)

# direct
corplink-rs config.json
# systemd
# config is /etc/corplink/config.json
systemctl start corplink-rs.service
# auto start
systemctl enable corplink-rs.service

# systemd with custom config
# config is /etc/corplink/test.json
# NOTE: cookies.json is reserved by cookie storage
systemctl start corplink-rs@test.service

windows 特殊说明

windows 中启动 wg-go 需要 wintun 支持，请到官网下载，并将 wintun.dll 与 corplink-rs 放到同一目录下(或者环境变量下)

macos 特殊说明

macos 要求 tun 设备的名称满足正则表达式 utun[0-9]* ，因此需要将配置文件中的 interface_name 改为符合正则的名字，例如 utun114514

配置文件实例

最小配置

{
  "company_name": "company code name",
  "username": "your_name"
}

推荐配置(自用配置)

{
  "company_name": "company code name",
  "username": "your_name",
  "password": "your_pass",
  "platform": "ldap"
}

完整配置

{
  "company_name": "company code name",
  "username": "your_name",
  // support sha256sum hashed pass if you don't use ldap, will ask email for code if not provided
  "password": "your_pass",
  // default is feilian, can be feilian/ldap/lark(aka feishu)/OIDC
  // dingtalk/aad/weixin is not supported yet
  "platform": "ldap",
  "code": "totp code",
  // default is DollarOS(not CentOS)
  "device_name": "any string to describe your device",
  "device_id": "md5 of device_name or any string with same format",
  "public_key": "wg public key, can be generated from private key",
  "private_key": "wg private key",
  "server": "server link",
  // enable wg-go log to debug uapi problems
  "debug_wg": true,
  // will use corplink as interface name
  "interface_name": "corplink",
  // will use the specified server to connect, for example 'HK-1'
  // name from server list
  "vpn_server_name": "hk",
  // latency/default
  // latency: choose the server with the lowest latency
  // default: choose the first available server
  "vpn_select_strategy": "latency"
}

原理和分析

飞连 是基于 wg-go 魔改的企业级 VPN 产品

配置原理

魔改了配置的方式，加了鉴权

猜测是：

因此，我们只需要生成 wg 的 key ，然后去找服务端拿配置，然后写到 wg 配置里，启动 wg ，就能连上服务端了

后续改动

2.0.9 版本(或者更早)新增了 protocol_version 字段，需要使用魔改后的 wg-corplink 才能连接

请求流程

Linux

graph TD;
    A[Password Login];
    B[Request Email Code];
    C[Email Login];
    D[Verify 2-FA];
    E[List VPN];
    F[Ping VPN];
    G[Connect VPN];
    A-->D;
    B-->C-->D;
    D-->E-->F-->G;

Android

graph TD;
    A[Password Login];
    B[Request Email Code];
    C[Email Login];
    D[List VPN];
    E[Ping VPN];
    F[Connect VPN With 2-FA Code];
    A-->D;
    B-->C;
    C-->D-->E-->F;

otp 实现

飞连的 otp 是使用的标准的 totp ，在 ua 为 Android 时，会在登录时返回 totp 的 token ，然后使用 totp 算法就能生成出当前时间的验证码了，然后在获取连接信息时传输该验证码，就不需要单独验证验证码了
