Description:
Tunnel TCP connections over ICMP packets
ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packets, commonly known as ping requests and replies. It acts as a proxy and can handle sockets and secured identification. . Those features can be very handy when working in a closed networking environment with firewalls and proxies.
