IP Packet Header Editing

[tomcatexodus]

Hey there, long time no post for me :P

Wondering, haven't dabbled with VB for awhile, but I've been reading around, and I used to do alot of Winsock proggin etc. I was wondering how one would go about editing the information of a TCP/IP Packet header, (eg spoofing, etc) in a VB 6 Enterprise environment.. Any information would be greatly appreciated, and if you need a more specific question, I can detail my inquiry for ya Thanks

Im sure that you cant do it with VB winsock component, if you are using the windows winsock library you might want to look up information/examples about RAW sockets, for making your own ip headers and everything else.

It's difficult to edit raw packets, having a look at this would be a start, it's a raw packet sniffer, pure vb6, shows you everything about the UDP/TCP header.

If you want to modify data about packets for a specific app, that is much easier, one way would be to create an app to act as a proxy server between the two real apps, and have all the data go through your proxy, this would enable you to edit it as much or little as you want.
