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

Use Android Client

A dedicated Android client for pingtunnel is now available, developed by the community.

pingtunnel-client

Big thanks to itismoej for developing this Android client!

Use Docker

It can also be started directly with docker, which is more convenient. It uses the 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
