Ostinato 0.5

Ostinato is an open-source, cross-platform packet/traffic generator and analyzer with a friendly GUI.

Ostinato aims to be "Wireshark in Reverse" and thus become complementary to Wireshark.

Note: Ostinato requires super user privileges to transmit packets. Please run Ostinato using "sudo" (or as root if your distribution doesn't support sudo).

Here are some key features of "Ostinato":

· Runs on Windows, Linux, BSD and Mac OS X (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)
· ARP, IPv4, IPv6, IP-in-IP a.k.a IP Tunnelling (6over4, 4over6, 4over4, 6over6)
· TCP, UDP, ICMPv4, ICMPv6
· Any text based protocol (HTTP, SIP, RTSP, NNTP etc.)
· 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
· User defined script to substitute for an unimplemented protocol (EXPERIMENTAL)
· 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

Requirements:

· Qt
· libpcap
