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
- “-key” parameter is int type, only supports numbers between 0-2147483647
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

- 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
- “-key” parameter is int type, only supports numbers between 0-2147483647
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
