Hello,
This is my first post, so, hello everyone. I have a homework about the above subject and some help with ip spoofing and changing the tcp header would be very helpful. My homework is based on this paper http://www.utdallas.edu/~edsha/papers/bin/synflood.pdf.
Thanks in advance

I haven't started the development. I am reading some papers. So, far i have reached to the plan as follows:
I am going to install an HTTP server (Apache maybe) and i am going to make some Syn Flood attacks from "spoofed ips" (i am going to use a VM) to the Server. Also i'll add a TTL (time to live) value on the Header of the (three-way-handshake) tcp protocol, also i'll create an algorithm that will manage the ttl+i, the hops and the icmp replies. Anyway, i need some help, or better some recommendations on papers about the issues that i mentioned on my first post. Also, some advises on how to achieve a congested network.
Thanks

Thanks hurtl0cker, i am thinking to use raw sockets.
