Ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packe
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. At first glance, this might seem like a rather useless thing to do, but it can actually come in your help in some cases.
Setting: You're on the go, and stumble across an open wireless network. The network gives you an IP address, but won't let you send TCP or UDP packets out to the rest of the internet, for instance to check your mail. What to do? By chance, you discover that the network will allow you to ping any computer on the rest of the internet. With ptunnel, you can utilize this feature to check your mail, or do other things that require TCP.
Here are some key features of "PingTunnel":
Tunnel TCP using ICMP echo request and reply packets
Connections are reliable (lost packets are resent as necessary)
Handles multiple connections
Acceptable bandwidth (150 kb/s downstream and about 50 kb/s upstream are the currently measured maximas for one tunnel, but with tweaking this can be improved further)
Authentication, to prevent just anyone from using your proxy
One computer accessible on the internet that is not firewalled (or at least allows incoming ICMP packets)
A computer to act as the client (this will usually be your laptop, on the go..)
Root access, preferably on both computers
A posix-compliant OS, with libpcap (for packet capturing)
