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.
