If I build it, will they come?

I originally wrote this post back in March ’06, but never posted it. Since then, I’ve been distracted with other tasks and openpacket.org has gone live. I’ve decided to post this now, because I’m tired of being lazy.

Honestly, I’m quite happy to see that someone has finally made something like this available- Tcpreplay users have been asking me where to get pcaps for a long time. I’ve been talking about doing something like this for years, but never had the time, so it’s great that someone else ran with it. Continue reading →
