• Fixed a problem with the checksum code. Some packet was generated with the wrong checksum! Please upgrade to rc3 ASAP.
• Scan mode. You can use hping as a low-level automated TCP port scanner. An example of output follows

# hping2 --scan known 1.2.3.4

Not responding ports:

• Major code rewrite (me)
• Fix for a problem about port number printing in TCP mode (thanks to Yann Berthier)
• MTU value sanity check in option parsing (Nicolas Jombart)
• Fix the use of -W option (Nicolas Jombart)
• strlcpy() when needed (Brieuc Jeunhomme)
• source routing and random bugfixes (Brieuc Jeunhomme)
• Fix a bug when using BSD and a PPP link as a default route, and more (Nicolas Jombart)
• --rand-source for random source addresses (me)
• --rand-dest for random destination addresses + manpage update (me)
• all the atoi() call was replaced with strto[u]l() (me)
• seq/ack setting using strtoul() instead of atoi() (Shachar Shemesh)
• DF added to the icmp and udp output (me)
• --port ++ fixed with UDP and enanched for TCP/UDP. Now the packets matches only with a sport that is in the range base_dest_port - current_dest_port (me) (Thanks to David Bar <dbar (at) Checkpoint (dot) com> for the original report).

• Ported to Solaris.
• A new output format, simplest to parse.
• The data is now taken aligned, so you should not experiment problems on not i386 based archs, like sparc.
• Improved traceroute support (rtt information and more)
• Improved BSD support (better interface handling, fix for 32bit pids, more)
• Improved interface managment under Linux and BSD, now the right interface is auto selected if not forced with the -I option.
• ICMP timestamp and address types implemented.
• TCP timestamp support, HZ and remote uptime guessing.
• Some option now implies some other, to make hping more comfortable, also some short alias for boring to type but often used options.
• Fixed some minor compilation problem under Linux and BSD.
• Fixed sequence numbers handling, now hping should run for days without problems.
• --seqnum endianess fixed.
• French translation of all the hping documentation.
• A number of minor bugs fixed and documentation updated.
