I'll definitely have a follow-up post later on, something more "personal" given my retirement, etc. It's a really emotional thing for me. I've certainly have had an amazing year, well, 17 years! I'll say more about that later.
Meanwhile, here are the slides from closing ceremonies: DC20 Network Closing (PDF 3MB)
I hope everyone enjoyed this 20th Anniversary Edition of DEF CON. There will never be anything else like it!

HAPPY SUNDAY MORNING!
Oh, sorry, are you hung over?
At least you're not alone!
Half the Network team is up & moving at least.
Here's your morning bandwidth graph!

The DC20-MEDIA file server is connected via dual 1Gb LACP trunk (2Gbps capability). It's been BUSY today! Good job!

Upload content to share with other con attendees (needless to say, you may want to trust content hosted by DEF CON more than random stuff shared by con attendees).
NETDrive (http://www.netdrive.net/download.html) is windows software that will allow you to easily map a drive via WebDav.
This software was also provided for you on the DC20 Conference CD.
Note:
NetDrive Settings:
Site Name: dc20-media.defcon.org
Site IP: 10.0.0.32
Port: 21
Server Type: FTP
Drive: "select a drive letter"
Account: connect as anonymous
(if you don't select anonymous, it will prompt you for a login; that means you're doing it wrong)
Under Advanced: force SSL for all communications.

Good Morning! It's amazing what just a couple hours sleep will do for you :)
We hope everyone had a great DEF CON 20 Friday night. Great turn out at all the parties, with some great entertainment (DJ's, bands, etc). Too many for any one person to see all of them (kind of like Disneyland, right?)
Everyone's going to be asking about DCTV - right, let's get on with that. Several of us were up late (me, Mac, Richard) working on ideas to get things fixed & back to working order. I think we finalized on Plan Echo(E). We still have Plan Foxtrot(F) in our back pocket. What was wrong? Combination of things. Primary issue was a codec that was mostly-standard, but slightly not. Couple that with newer versions of software that didn't handle the "slightly not" part right. We found the right combination of software and command-line flags, and at 12:30am last night declared (very quietly, so we didn't jinx it) victory - at least with our proof-of-concept we setup in the NOC. We'll re-deploy equipment in a few minutes and verify our hypothesis in production!
Again, we apologize that things weren't running well yesterday. This has been our #1 priority to resolve since yesterday morning and appreciate your patience. (I know I sound calm now, but I was such a stress-ball last night!!).
Other than that, we are having a lot of people using wifi, and great traffic. I think we're going to have to upgrade next year. Our controller is running out of memory throughout the day. Rukbat has been amazingly diligent at sitting quietly in the NOC, all day long, clearing memory, keeping it running as best he can. Can't say enough good things about Rukbat, seriously - I should do an entire post about this guy! He's bloody incredible! But meanwhile, if you do see intermittent loss of connectivity, either wait a minute or two (I know, patience is hard when you're trying to pull up a webpage with someone standing next to you waiting on it) - or email us (noc-at-defconnetworking-dot-org) and let us know. A couple people did yesterday, it's helpful, so thank you guys.
Looks like all afternoon ya'll were using some massive bandwidth. Here, have a look...

We discovered the "lost checkbox" that needed to be un-checked. Now FTP clients can connect, get directory listings, etc.
The issue was mostly on Windows clients.
You should be all set now
So...LEECH!
...and contribute if you have anything!

From a gentlemen who figured out his LINUX problems with the DefConSecure WiFi - we wanted to pass this along.
"RESOLVED have to add .cer to /usr/local/share/ca-certificates and run
sudo update-ca-certificates
OpenSSL must be aware of the CA cer or validation fails"
Hope this helps!
