Here's your Saturday morning update... wait, it's Saturday already?!

Wireless is working well again - we think we have a hold on the rebooting AP's. We are curious if the ninja badges are interfering with wifi (or is our wifi interferring with the badges? The badges have the ninjas; does that make DefCon's wifi the pirates?! FIGHT!)

Wired network (speakers, press, staff) - 5x5. Someone asked for a 30'ft cross-over cable today. Welcome to DefCon.

Our ISP (Sparkplug) called us last night -- "Oh hey, we went ahead & opened your line up to 100Mb - use it!" - so please, for the sake of the children, use the net! :) (kick-ass of them to do that, btw!!)

Somehow some of us got some sleep last night - not sure how we did that, but there it is.

We've seen that, roughly, 50% of the wifi users are on secure wifi. We'd be curious for any feedback on how things are going out there - email us (noc at defconnetworking dot org, or @TheLockheed on Twitter).

The irony is that in the DefCon NOC - we have low wifi coverage.

Enjoy your Saturday! Get out, see the talks, make some friends, talk to people. DefCon is an amazing experience, get the most out of it that you can!! Here's a quote from a DefCon Virgin this year, "This really is the best experience I've had in my life. And I'm being very literal. Thank you for your help and support."

Have some bandwidth & users graphs...

Can you tell where we re-booted the wireless network? :)

The wifi access points are randomly rebooting (cycling about every 15 mins). We're working on fixing it now.

We found a fix for all you iPhone/iPad users. It's a known issue with Apple devices, apparently.

The work-around is here.

Thank you Princeton IT Group for the help!

Bandwidth & Users at 12:42p - we're clearly using the bandwidth (THANKS!) and have more users online simultaneously than ever before. Half of you are on the DefCon-Secure wifi network.

We're continuing to research the issue with iPhones / iPads on the network. We're currently testing a potential resolution and will update you when we have confirmed it.

DefCon has opened. The network is functioning.

Two issues you should be aware of...

1) https://wifireg.defcon.org - Sorry, we forgot to ask DT to put this in his public DNS servers (fail!) - so that's happening now. It works from the internal network ok. Or from the external network you can use https://208.95.78.182 until DNS propogates.

2) We've noticed some mobile devices (mostly ipads) are having issues renewing their IP after coming out of sleep. We're checking it out and seeing if we can adjust some things on the network side that may help. We think it has to do with having so many AP's that clients are talking longer than expected to settle on which AP to associate with.

Otherwise, if you have any issues with the network, email us, or let dispatch know so we can check into things!

Had a long day yesterday - we caught up on things and got things to about 80% complete.

The understanding of DefCon hit Jesse...
"DefCon is all about drinking all day and staying out until 0600 and then getting up at 0700"

This morning we're running around, getting everything patched up, switches dropped, wifiz re-verified. Everything is on-track to be finished by the end of today.


The first day of setup ended about midnight last night. The Inter-webs came up quickly after we had breakfast. The NOC is live & fully functional. The Queen Victoria Pub doth rocketh. Our WiFiz got delayed, but since it's the same (physical) setup as last year we just need to unpack & go. App servers are up & functional. All & all, things are coming along nicely. We have to be completely done by EOD Wednesday (which is anytime before 8a Thursday). The contest area is still going to be hard spot to network up, but the hotel guys are doing their best to make it easy(er) on us.

Day Two starts now.

Two days before the DCNET staff arrive in Vegas.
Everything's ready.
Most things are packed up.
- PC's
- Servers
- spare servers
- cables
- switches (old & new)
- radios
Internet connection is already dropped & active.
Hotel is pulling cable already.
WiFi's setup
- we setup 802.1x/WPA2
- now someone's going to talk at Blackhat about a possible sploit?
- Bah!
DCTV's rarin' to go.
DefCon Mobile Edition is ready for production.

What's left?
Oh yeah, last minute requests :)

I hope the Queen Victoria Pub in the Riv took my advise and stocked up for us! (I warned the owners last month).

We're all really excited about this year - it's gonna rock!!

WiFi self-reg is all set, tested, validated.

Data for all speakers, con-events, and DJ's are loaded into the World Domination Database (thanks to Neil & Nikita for providing the data) - the back-end for the DefCon18 Mobile Edition agenda. Still have to load contests once I get some more infoz. t3ase continues his work on CSS-ifying DC-ME (no pressure!).

Plus, Mac & Videoman have the core infrastructure laid out & base configs completed.

There's not much more left to do other than show up & hook it all together. Two weeks today until the DefCon Networking Team lands in Vegas. Not long now, Papa Smurf!

effffn & I stayed up late last night & got the secure wifi configuration working. I want to do some cleanup on the radius config files, but we have working WPA2 + 802.1x setup!

I'm setting up "self registration" so attendees can create their own logins for the system today. I hope Neil doesn't mind I'm stealing his CSS :)

We got tweeted! Well, it's not as being slashdotted (don't get any ideas!) - but thanks for DT or Neil for giving us the shout-out!

20 days until DC18 starts!

It's definitely going to be an interesting year with floorplan changes, wifi changes, focus on DCTV & a/v streaming (shouts to DJ Great Scott for being so easy to work with, btw!). And the DefCon Confessional is BACK!

We're even jumping in and providing a "Mobile Edition" agenda webapp that will be available locally. We're testing against iPhone, Android, and Blackberries. Look in the program for details! (you can login and have some FourSquare-like functionality if you want to keep up with your friends and who's seeing what talks, going to what bar).
