Chrisso -

Thanks for letting everyone know you were one of the winners; if nobody spoke up, I was willing to take the heat in exchange for ensuring people's privacy. There are other winners out there, but whether or not they come forward is again totally up to them. Thanks again.

Checking in Sunday night at the Rio - if anyone is going to be in Vegas early, ping me via twitter: @hackingdojo or @thomas_wilhelm

Winners are picked, and emails sent. Congrats to the winners!

As mentioned earlier, I'm not announcing the names of the winners, but have encouraged them to let everyone know.

Oh, an you can leave the router alone.

Another option is to put both the BT VM and the De-ICE VM images on NAT, and manually change the BT IP address to something like 192.168.1.10... They will talk to each other, assuming both VMs are on the same computer.

I designed the De-ICE disks to imitate the real world, and one thing I always did as a sysadmin was turn off things like ping... So, I did the same with the 1.100 disk. The educational purpose behind turning it off was to teach people to use multiple tools to validate everything they do. As my students hear me say (too frequently), "always be cynical and use more than one tool for each task."

Here's my last effort to get people to sign up at the Hacking Dojo before June 1, in order to get them eligible to win an iPad 2 (odds are 1 in 10).

For Today Only, I've reduced the 1st month's subscription for membership in the Shodan (Foundational) Certified Penetration Tester course at HackingDojo.com by over 50%... but again, for today only. Thanks!

I've had a couple questions on the iPad 2 giveaway, specifically the odds. Basically, there is a 1 in 10 chance a student wins an iPad...

10 students = 1 iPad given away
20 students = 2 iPads given away
30 students = 3 iPads given away... etc.

I won't be announcing the winners for purposes of privacy, but I will encourage them to speak up and let the world know. See HackingDojo.com for specific details on the give-away.

1) I'm a college professor and teach hacking, write about hacking, and live by hacking.

2) Someone who obtains your MAC address does not have free access to your PC. There has to be a vulnerability, misconfiguration or human error that permits it. It's like saying I can steal your computer data by simply knowing your snail-mail address. I'm assuming she said some other things as well, and didn't just leave it at that statement.

3) Yes, there are programs that go from the data link to application (hitting all the ones in between)... in fact, you're using one now - the web browser.

I'm not sure you understand the way the TCP/IP stack works - whenever you send a packet to a computer (using IP address) the link layer has to be involved (which includes the MAC protocol). And if you want to talk between applications, then you have to also progress through the Internet layer and Transport layer. You can't really talk with the system until you get past the Internet layer (and then it's not very meaningful until you get to the application layer).

If you're trying to avoid using IP addresses, and only communicate between systems at the link layer, then focus on those protocols at that layer... but MAC and all the other protocols at this layer have the only function of moving packets between different systems.

This question seems a bit nonsensical to me - again, I'm not sure you understand how the stack works.

The open class times are:
Monday: 6pm, 8pm, 10pm Eastern
Tuesday: 8pm GMT

Thanks for the question!

Time to CHANGE the deal -

From now until Monday night, anyone who signs up for either the Shodan or the Mukyu (Novice) class and remains a member through July 15 will receive a free Kindle copy of my book titled "Professional Penetration Testing," published through Syngress. And of course, they will also be eligible to randomly receive one of the iPad 2s being given away to students!

Time to sweeten the deal -

For the next 24 hours, anyone who signs up for the Shodan class and remains a member through July 15 will not only be eligible to randomly receive an iPad 2, but also receive a free copy of Ninja Hacking, in either a paperback or kindle version (their choice).

To answer an email...

Yes, if you enroll in the novice class scheduled for July-August, you are eligible for the drawing, assuming you sign up before June 1. Be warned, there are only 8 slots in that class still open, and they fill up quickly.

We are very close to meeting our maximum class size at HackingDojo.com, and I wanted to give a HUGE push to get the class filled, so I am randomly giving away an iPad 2 (16GB WiFi) for every 10 students enrolled!

To be eligible for the random drawing for one of the iPad 2 tablets,  you must be enrolled before June 1, and continue to be enrolled by July 15, 2011. The drawing will be conducted July 15.

Students who are currently enrolled and maintain their enrollment on July 15 will also be included in the drawing.
