Hi, How can one implement custom header network protocol. I mean header that wraps regular network packets like ethernet, udp, tcp, etc... The sending of this custom packets is done between processes running locally. ie. I get a Ethernet packet, inspect it, then add my custom header and forward it to another process that listens to a socket, and expect to get data wrapped with this custom header.
What is a good way to go about and implement this thing?
Have you looked at the tun/tap drivers?
Yes I did, they can work for me, but I need to modify the code. They expect certain protocols and are not passing anything. It is a bit ugly to go this way.
Also, try asking this question on a network specific list.
