All your torrents are belong to us...



Network utilization currently at 94% (on inbound).
For the mathematically challenged, that's 94Mb (we have a 100Mb circuit).
Outbound is running about 20Mb (probably torrents seeding).


9:30p - the day is largely over (other than parties at this point).
Not much bandwidth consumed today - a few spikes, but generally hovered around 10-14Mbps.

DCTV seems generally well-received. The feeds from the cameras don't mix speaker & slides so we had to pick one feed to broadcast. We're already talking about major upgrades next year - but since this is the first time since the AP we've been able to do this, we got a lot of ideas for making DC20 a major step-up.

Oh, and we got our first hate-mail today! So sad that the world is full of hate like that. However, we got many more people who emailed in, or stopped us in the halls, or tweeted us, thanking us for the network. Apparently many more people knew how to use wifi. A number of people said it was much better than over at Blackhat.

However, it's not about us -- thank YOU for coming, enjoying the conference, getting out, participating, etc!

We found some guys who setup a rogue DHCP server. One of the contests, actually. Running a rogue DHCP server off a hard-line that we can trace through our switches easily? Not so smart. Extermination protocol Zeta-3 was triggered, and successful.

If you're doing anything cool with IPv6 here - let us know! (noc at defconetworking dot org).

Enjoy the parties tonight - be safe, have fun!

Carry-over from last year - iOS (Apple) products have issues on the wifi.

The work-around is here.

A reminder that there is a Blood Drive tomorrow afternoon. You can give specifically to help out Barkode (Matt Lewis), or to donate in general.

Priest commands you...!

#DefCon Mobile Edition v2.0 for DC19 is LIVE! Check out from your mobile phone for speakers, events, and contest info!

(many thanks to t3ase for staying up late much of the last week putting the final touches on the new site!)

Just in case we run out of bandwidth, we have a backup! :)


"DefConSecure" is ready for use, although we still have some AP's to deploy once rooms are turned over to us. However, if you're looking to get prepared for DefCon, get your login setup from home (or other network you "trust'). Go to and reserve your login.
