LoneStarRuby 2015 - Building a binary protocol client in Ruby: A magical journey!

30 minutes
    By Trevor Rosen and egypt Sometimes we can forget that there's more under the (networking) sun than HTTP. Rapid7's Metasploit team has been working for awhile on a new, pure-Ruby library for Microsoft's SMB protocol. Doing work like this means analyzing wire traffic, working with binary structs, and wrapping everything up into a nice, clean set of abstractions. We'd like to share the developer workflows and lessons learned. If you've ever wondered how to set about building a library for a binary protocol, how to reverse-engineer the byte-by-byte traffic on a network, or thought it would be cool to understand Ruby's networking capabilities from the ground up, this talk is for you!
