-## 使用
+## Usage
-### 安装服务端
+### Install server
-- 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
+- First prepare a server with a public IP, such as EC2 on AWS, assuming the domain name or public IP is www.yourserver.com
+- Download the corresponding installation package from [releases](https://github.com/esrrhs/pingtunnel/releases), such as pingtunnel_linux64.zip, then decompress and execute with **root** privileges
```
-sudo wget (最新release的下载链接)
+sudo wget (link of latest release)
sudo unzip pingtunnel_linux64.zip
sudo ./pingtunnel -type server
```
-- (可选)关闭系统默认的 ping
+- (Optional) Disable system default ping
```
-echo 1 >/proc/sys/net/ipv4/icmp_echo_ignore_all
+echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
```
-### 安装客户端
+### Install the client
-- 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
+- Download the corresponding installation package from [releases](https://github.com/esrrhs/pingtunnel/releases), such as pingtunnel_windows64.zip, and decompress it
+- Then run with **administrator** privileges. The commands corresponding to different forwarding functions are as follows.
+- If you see a log of ping pong, the connection is normal
-#### 转发 sock5
+#### Forward sock5
```
-pingtunnel.exe -type client -l :4455 -s www.yourserver.com -sock5 1
+pingtunnel.exe -type client -l: 4455 -s www.yourserver.com -sock5 1
```
-#### 转发 tcp
+#### Forward tcp
```
-pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
+pingtunnel.exe -type client -l: 4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
```
-#### 转发 udp
+#### Forward udp
```
-pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455
+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
+### Use Docker
+It can also be started directly with docker, which is more convenient. Same parameters as above
- server:
```
-docker run --name pingtunnel-server -d --privileged --network host --restart=always esrrhs/pingtunnel ./pingtunnel -type server -key 123456
+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
+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
+## Test
-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
