The only bummer bout the Encrypted network is that it kind of kills the Wall of Sheep which is always a hoot!

Re: DC19 Network

Good to hear about keeping the mobile agenda app. The only thing I would encourage is maximizing cross-device support. This is admitted a selfish request as I recently switched from my old iPhone to a new Blackberry. That said, I also realize there are limitations to this request and will happily survive using my paper agenda if Blackberry (or other device) support isn’t perfect.

I figured the network team had Cacti (or something similar) and other monitoring software running. I don’t have any intention of sitting around my room staring at it but I do find it interesting to see network trends/events as they are occurring. Being one of the most hostile networks in the world, this should provide some interesting insight.

Thank you for reminding me about the SPAN ports. I’m not much of a programmer but I have lots of time to come up with something.

Contest you say… You have my attention! I will have to keep a close eye on the contest page.

802.11n would be sweet for the same reason I think IPv6 is sweet. It’s hard to say whether or not it will actually be of true value without seeing last year’s data on access point bandwidth utilization or committing to doing something crazy like pushing high definition DCTV over the WiFi network. Still cool though.

Depending on how the hotel’s network is setup, multicast might… I am thinking I will just shut up now and have something to look into when I get into Vegas that Thursday.

I completely agree with you about not letting too much in or out of the network. I will give the idea of letting more in/out some more thought and see if I can come up with any more specific ideas.

Thanks!

Re: DC19 Network

Awesome - we'll keep up the stuff from last year then! I'm glad the mobile agenda app worked out well! I wasn't entirely sure if people would dig it, or just go "eh." I looked back at my notes and 1300+ people used it, so I'm happy about that :)

More live log viewing

Some of that's not hard for us to do. We've got the MRTG/Cacti graphs already, so it's just a matter of making those available for everyone to see. We've had a focus on monitoring the last few years, now we can just augment that as "monitoring & publishing" :) console-log scroll, eh? Hmmm. Easy enough, and if people want to stare at it, sure.

The protocol analysis - this is actually a great idea where YOU (collectively) can get involved! We can give span ports to people if they want to look at the traffic flows, do some analysis, and especially publish to the con in real-time. Why not? :)

IPv6 support

You just gave me a great idea for a CONTEST!

IPTV/Multicast Video

We are actually talking about what it would take to upgrade our gear to support 802.11n - discussion is happening in the back rooms now. I doubt we could get into the hotel network (the one that runs to rooms) - but what you're really talking about is making the DCTV content available to the rooms - outside of the con network.

More outside traffic in

Go on.... say more :) One thing we also have to pay attention to is making sure con attendees get real benefit for their price of admission - if too much network content is available whether you're on-site or not, then it de-values the effort to *go* to DefCon. It's always a balance, right? So if you think of something we should be "enabling" more from the outside, I'm all ears!


Thanks for the ideas - definitely got us thinking!!

Re: DC19 Network

The mobile agendas were great and would love to see them again along with more mobile friendly web content. Not having to carry around (and tear up/lose) my official schedule was a great convenience. The auth/encrypted WiFi was also great as it provided a secure (at least to the best of our knowledge) alternative Internet access to the before mentioned issues with cellular carriers. The FreeForAll area is great and I consider it to be a staple of the con. And obviously, the more bandwidth the better. As for new...

More live log viewing - I would love to see (almost) live MRTG graphs of bandwidth, IPFIX traffic breakdowns, CPU/mem/associations/etc of the various network devices. Maybe we could come up with a dynamic way of showing the TCP/UDP (or higher layer protocols like BitTorrent) data streams as they are built, used, and torn down? It might also be interesting to see streams of the debug/syslog/consoles of the various network devices.

IPv6 support - I have no good reason for this other than to do it just because we can. Many people complain IPv6 isn't secure because it hasn't been fully vetted in the field. I can't imagine a better place to give the vetting process a booster shot than the Def Con 19 network.

IPTV/Multicast Video - Another cool addition I would like to see is live (VLC compatable) multicast IPTV streams of the presentation hall video feeds made available on some or all of the various networks available to us at the Rio (inspired by some of the discussion occurring in the Defcon 19: Viewing Suite Planning thread). My geeky nature makes me want to say go hi-def (hmm... hi-def... def con... "hi-def con"?) but admittedly, I realize the concerns using WiFi as a distribution medium would create (bandwidth, RF noise, jitter, packet loss, etc). Is it realistic to upgrade the entire WiFi network to 802.11n 4x4 mimo (better question, would that be enough to actually help)? Maybe a smaller/separate/dedicated wireless network with only the video streams could be put into place? Could we splice into the hotel network and stream wired/wirelessly to the rooms (providing an alternative/augmentation to hotel's four avaliable conference channels... multiple laptops = "picture-in-a-picture" solution to the issue of having multiple streams per room and lack of avaliable CCTV channels)? I don't see Unicast streaming the video from the con to the Internet as practice (bandwidth or cost effective) but maybe we could cross connect with a carrier that has access to mBone/Internet2 and multicast stream to the Internet that way (local university... UNLV)?

More outside traffic in - Yes, I know, this is inviting issues. I also admin that more than one of my other suggestions above has this same issue but I ask... is that not the fun of Def Con?

I know I posed more questions/suggestions that requests/answers but hopefully this will fuel some more ideas and go from there.

Last year we did a bunch of new stuff...

802.1x WiFi Encryption
FreeForAll Area
DefCon Mobile Edition Agenda
Bigger GB's

Was that useful? Did it work for you? Should we continue it?
(don't ask me to fix AT&T's 3G network - I leave that to you :)

What else do you want? New Stuff? Old Stuff?
