## Usage
### Install server
- 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 (link of latest release)
sudo unzip pingtunnel_linux64.zip
sudo ./pingtunnel -type server
```
- (Optional) Disable system default ping
```
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
```
### Install the client
- 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
#### Forward sock5
```
pingtunnel.exe -type client -l: 4455 -s www.yourserver.com -sock5 1
```
#### Forward tcp
```
pingtunnel.exe -type client -l: 4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
```
#### Forward udp
```
pingtunnel.exe -type client -l: 4455 -s www.yourserver.com -t www.yourserver.com:4455
```
### 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
```
- 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
```
