icmptx - Tunnel IP over ICMP
icmptx [ -s | -c ] server
icmptx allows you to pass IP packets via ICMP. Say that you are sitting in a cafe and you want to use the wireless network, but it costs money. If that network allows ICMP traffic (i.e. you can ping machines on the Internet), icmptx is your friend.
