Pingtunnel is a tool that advertises tcp/udp/sock5 traffic as icmp traffic for forwarding.
## Note: This tool is only to be used for study and research, do not use it for illegal purposes
## 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 GUI client (recommended by novices)
- Download the gui version of qt from [pingtunnel-qt](https://github.com/esrrhs/pingtunnel-qt)
- Double-click the exe to run, modify the server (such as www.yourserver.com), listen port (such as 1080), tick sock5, other settings can be default, and then click _GO_
- Everything is normal, there will be a ping value on the interface, and then you can click X to hide it in the status bar
- Set the browser's sock5 proxy to 127.0.0.1:1080, If you do not connect to the Internet, a socks version not supported error log appears, indicating that the browser's proxy is not a socks5 proxy.If it prompts a non-secure connection, it means there is a problem with dns. Check "Use socks5 proxy DNS query" on the browser.
### Install the client (recommended for high play)
- 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 (recommended for high play)
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
```
## Test
download the centos image [centos mirror](http://mirrors.ocf.berkeley.edu/centos/8.2.2004/isos/x86_64/CentOS-8.2.2004-x86_64-dvd1.iso)
