This program manipulates the TCP/IP header to transfer a file one byte at a time to a destination host. This progam can act as a server and a client and can be used to conceal transmission of data inside the IP header. This is useful for bypassing firewalls from the inside, and for exporting data with innocuous looking packets that contain no data for sniffers to analyze.
