Re: how can I rewrite TCP/IP packets
You need an "application-layer gateway", something that's capable of inspecting "layer 7" of the packet. These would be specific to individual protocols (HTTP, etc). It's not something you should attempt to home-brew unless you're an experienced programmer familiar with the TCP/IP stack. |

| Inspecting a packet is easy, and I have numerous tools for that. It's the modification part that I'm having trouble with. Do you happen to know any concrete example that doesn't cost an arm and leg? As for programming, I think I'm somewhat experienced, but not with the TCP/IP stack.
As for the previous comment -- nope, it's neither a quiz, nor a homework. It's a pet project. |

| You may want to read up TCP/IP basic to lead you to TCP/IP programming. A good TCP/IP book is always the W. Richard Stevens' series the TCP/IP Illustrated; Volume 1 (The Protocols), Volume 2 (The Implementation), and Volume 3 (TCP for Transactions, HTTP, NNTP, and the UNIX Domain Protocols).
To supplement, read up also Stevens' books of Unix Network Programming; Volume 1: The Sockets Networking API, Volume 2: Interprocess Communications. |
