Tcp Packet

Gspoof is a GTK+ program written in C language which makes easier and accurate the building and the sending of TCP packet with a data-payload or not. It's possible to modify TCP/IP fields also Ethernet header working to Link Level.

interfaceTrafcalc calculates the size of the TCP-payload on a system via packet capturing and connection tracking at the user level instead of the IP level. The program uses a pcap (a library for Packet CAPturing) callback function which is called for every incoming (tcp) packet. This function...
