pingtunnel 是把 tcp/udp/sock5 流量伪装成 icmp 流量进行转发的工具
[Readme EN](./README_EN.md)
## 注意：本工具只是用作学习研究，请勿用于非法用途！！！
## 使用
### 安装服务端
- 首先准备好一个具有公网 ip 的服务器，假定域名或者公网 ip 是www.yourserver.com
- 从[releases](https://github.com/esrrhs/pingtunnel/releases)下载对应的安装包，如 pingtunnel_linux64.zip，然后解压，以**root**权限执行
```
sudo wget (最新release的下载链接)
sudo unzip pingtunnel_linux64.zip
sudo ./pingtunnel -type server
```
- (可选)关闭系统默认的 ping
```
echo 1 >/proc/sys/net/ipv4/icmp_echo_ignore_all
```
### 安装客户端
- 从[releases](https://github.com/esrrhs/pingtunnel/releases)下载对应的安装包，如 pingtunnel_windows64.zip，解压
- 然后用**管理员权限**运行，不同的转发功能所对应的命令如下
- 如果看到有 ping pong 的 log，说明连接正常
#### 转发 sock5
```
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -sock5 1
```
#### 转发 tcp
```
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
```
#### 转发 udp
```
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455
```
### Docker
也可直接用docker启动，更方便。参数同上
- server:
```
docker run --name pingtunnel-server -d --privileged --network host --restart=always esrrhs/pingtunnel ./pingtunnel -type server -key 123456
```
- client:
```
docker run --name pingtunnel-client -d --restart=always -p 1080:1080 esrrhs/pingtunnel ./pingtunnel -type client -l :1080 -s www.yourserver.com -sock5 1 -key 123456
```
## 效果
下载 centos 镜像 [centos mirror](http://centos.s.uw.edu/centos/8.4.2105/isos/x86_64/CentOS-8.4.2105-x86_64-dvd1.iso)，对比如下
