I saw this on another mailing list and thought it might be of interest to many people on this list as well, so I'm posting it here for the benefit of those who may not have seen it elsewhere.

Ostinato
<http://ostinato.googlecode.com/>
Ostinato is an open source, cross platform packet/traffic generator
and analyzer with a friendly GUI.
A stated goal for the project is to be "Wireshark in Reverse" and thus
become complementary to Wireshark
Features
* Runs on both Linux and Windows (Will probably run on other
platforms also with little or no modification but this hasn't been
tested)
* Support for the most common standard protocols
* Ethernet/802.3/LLC SNAP
* VLAN (with QinQ)
* IP, ARP
* TCP, UDP, ICMP
* More protocols in the works ...
* Modify any field of any protocol (some protocols allow changing
packet fields with every packet at run time e.g. changing IP/MAC
addresses)
* Stack protocols in any arbitrary order
* (EXPERIMENTAL) User defined script to substitute for an
unimplemented protocol
* Create and configure multiple streams
* Configure stream rates, bursts, no. of packets
* Single client can control and configure multiple ports on multiple
computers generating traffic
* Exclusive control of a port to prevent the OS from sending stray
packets provides a controlled testing environment
* Statistics Window shows realtime port receive/transmit statistics and rates
* Capture packets and view them (needs Wireshark to view the captured packets)
* Framework to add new protocol builders easily
A screencast showing basic usage is here -

Screenshots are here -

Binary (Win32 only) and source packages are available now for the 0.1 release.
The wiki (http://code.google.com/p/ostinato/w/list) has
* a User Guide to get you started (with a Quickstart section)
* a HOWTO - write a (quick and dirty) script to substitue for a
missing protocol
* Developer documentation on how to add support for new protocols.
I humbly invite the community to participate in and contribute to
Ostinato development. Like Wireshark protocol dissectors, it is easy
to add protocol builders to Ostinato - check out the HOWTO
(http://code.google.com/p/ostinato/wiki/ProtocolBuilderHOWTO)
Please do share your impressions and/or questions on the mailing list

configured so that anyone can post without needing to join)
