 |
|
Hi,
I need the following:
I want do doe TCP/IP over ICMP. It should be the way that I see a normal device ethX on my system. I can work on it with ifconfig and so on. BUT the difference should be, that this device does all traffic over ICMP instead of TCP/IP.
Does such a kernel module exist?
Thanx a lot |

first, as icmp is not used to carry user data, there is no sense in doing so.
second, technically a icmp packet is constructed from a udp segment.
third, icmp lives at layer 3 of the osi model and has nothing to do with network devices.
so, maybe if you tell us what you'd like to do we can help you. |

I want to write a module for that.
Reason:
Our firewall does only allow icmp pakets from outside to inside. so i want to tunnel over icmp |

So basically you want to risk your job but well... http://sourceforge.net/projects/itun/ as a first start.
