This is a fixed version for the famous Firewalk tool (http://packetstormsecurity.org/UNIX/audit/firewalk/) that couldn"t be compiled on modern nix boxes.
Modified fixed source code included.

To get the correct IP TTL that will result in expired packets one beyond the gateway we need to ramp up hop-cou
