The more traditional traceroute(8) sends out either UDP or ICMP ECHO
packets with a TTL of one, and increments the TTL until the destination
has been reached. By printing the gateways that generate ICMP time
exceeded messages along the way, it is able to determine the path
packets are taking to reach the destination.
The problem is that with the widespread use of firewalls on the modern
Internet, many of the packets that traceroute(8) sends out end up being
filtered, making it impossible to completely trace the path to the
destination. However, in many cases, these firewalls will permit inbound
TCP packets to specific ports that hosts sitting behind the firewall are
listening for connections on. By sending out TCP SYN packets instead of
UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common
firewall filters.
rain is powerful tool for testing stability of hardware and
software utilizing IP protocols. It offers its users the
capability of creating their own packets with a wide variety
of command line options.

+ lots of additional mods

+ lebel@ reviewed
From Changelog:
* added new IP defragmenter, spp_frag2
* added new stateful inspection/tcp stream reassembly plugin, spp_stream4
* Snort can now statefully detect ECN traffic (less false alarms)
* stream4 can now keep session statistics in a "session.log" file
* added new high-speed unified binary output system, spo_unified
* added new data structs/management for tag code
* added -k switch to tune checksum verification behavior
* added -z switch to provide stateful verification of alerts
* modified bahavior of http_decode, now only alerts once per packet
* added unique Snort ID's to every Snort rule, plus generator, revision
and event ID info to each alert
* detection engine only alerts once per packet now, tcp stream code doesn't
generate another alert packet if a previous one already alerted for that
stream
* fixed signal handling on svr4 systems
* added enhanced cross reference printout to full/fast/syslog alert modes
* added new high speed checksum verification (on x86) routines
* added new ARP spoof detection preprocessor from Jeff

Net::IPv4Addr provides functions for parsing IPv4 addresses both
in traditional address/netmask format and in the new CIDR format.
There are also methods for calculating the network and broadcast
address and also to see check if a given address is in a specific
network.
