Whew. I can relax.
For the past 2-3 months, I’ve been working on my first real Objective-C project (my iphone app is still going, it just took a back seat to this): An application that will read tcpdump output and animate the packets over time using their inherent byte / packet structure
And now…it’s up and in beta-ish quality. (Meaning it works, though some error checking and minor features arent quite where I want them.)
You can download it here for free: http://sintixerr.wordpress.com/pkviz-packet-visualizer-and-animator/
See it in motion here:
This project was important to me and has been a long time coming. I’ve wanted to write a packet visualizer since I first started working with data viz 5 or so years ago at NetSec and was using Advizor. That tool cost thousands of dollars per seat, didnt really animate (at least the way I needed), and only parsed CSV or databases. The free tools – like GnuPlot, just weren’t up to the task at all.
I also wanted something that could plot out data in interesting, pretty ways for some art projects I have in mind.
So, I originally started this time around on a quest to write a short python parser for tcpdump ascii hex output to put into <some generic viz tool> just to get started…but somehow I ended up writing a full-fledged visualizer (my first GUI project ever, I might add!). The learning process was a blast – I feel like I’m a much better coder for it – and I’ll be able to extend/expand on this to use for other art and security projects that are on my plate or are coming up.
I’m pretty excited about it. To see this finished through after years of whining to myself about it, procrastinating, and genuinely not having enough time, is pretty awesome. I’ve even already created a couple of cool shots that I’m happy to call “art” (granted, there is some photoshop processing here, but they’re both true to their originals!):
Anyway, Mac Users, check out the tool and let me know what you think!
