Pingtunnel

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, 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, 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
