ttlscan is a libnet/libpcap based program that sends a TCP SYN packet to
each port of the host given via the command line. The answer is sniffed
of the wire. I use it to detect hosts that fake services by forwarding
packets to another host (behind a firewall). By reading header files
like the TTL, window size and IPID you might be able to see the OS
running on the host behind the firewall.
