Racket version 1.0.2 released, now in Metasploit

Many months back I got word that Metasploit would be including Racket to handle much of its reading and writing of raw packets. Racket was selected for its speed and ease of use and I'm glad to see my work pay off. To celebrate this, I'm releasing 1.0.2, which includes:

• VRRP
• SCTP
• EGP
• General cleanup so as to not trash namespaces
• Various bug fixes
• Numerous documentation and examples cleaned up

Give Racket a whirl, I assure you you'll find it useful. I openly encourage testing, bug reports, suggestions or solicitations for additional functionality.

Racket -- Ruby Raw Packet Fun

This is one of those projects that I've been sitting on for a good 6+ months. Only over the last 2-3 have things really started to come together. I am happy to release Racket, a Ruby gem designed for crafting and analyzing raw packets.

Towards the end of the initial development of Racket, I caught wind of Scruby because that is what Metasploit 3 is using for much (most?) of its raw packet duties. In the TMTOWTDI spirit, I kept up development and actually think that Racket's purpose is a bit different than that of Scruby.

Installation is fairly simple:

gem install --source http://spoofed.org/files/racket racket

Documentation and examples are published but need some touching up. Among some of the more amusing/useful examples are:

• cdp-spew: exactly what it sounds like. Creates and floods the network with random Cisco Discovery Protocol (CDP) packets
• hsrp_takeover: passively listens for and actively performs "takeovers" for all discovered Hot Standby Router Protocol (HSRP) instances
• tcp2udp: Listens for any tcp traffic and turns the packet back around, sending it back at the source as a UDP datagram. No point

Racket requires that you have Joel VanderWerf's BitStruct and Marshall Beddoe's PcapRub installed.

Enjoy! Comments or suggestions are welcomed.
