Thanks, all set.

Don,

Thank you so much for replying. I had a feeling it was considered assumed knowledge. In my case, I never touch Linux until this week. So as I watched the shows I was seeing all the possibilities of the server, but I couldn't find the resource on how to connect to it. Everywhere I looked it was assumed that the connection was already made.

I realize that there isn't a certification for it, but it would really tie things together if you ever did some multi platform client side shows.

Justin,

Every ITProTV monthly and premium subscriber can request 1 practice exam key per month. After logging in, navigate to the Course Library. Scroll down to the CompTIA section of the library then you can click on the green View Course button on right side of the page. Above the right corner of the video, you'll see a link for Request Practice Test Click on it and it will automatically generate the key for you with instructions of how to get setup and use MeasureUP for your assessment tests.

Thanks Ronnie for your reply. I just went ahead with the regular proctered exam. Thanks to you and Don I passed with flying colors. My third certification I've passed with ITProTV. Thanks guys!

Trevor,

Nate just let me know that the show notes are up and available for that episode now!

Hi Ronnie,

Makes perfect sense. Thanks for the quick response!

I'm not 100% sure but I think just the renewal is necessary. If you have a DHCP address with lease time left and reboot when the DHCP server is unavailable, you will keep using the same address. If you do an ipconfig /release and /renew while the dhcp server is unavailable, you will get a MS 169 bogus address. If you reboot while the DHCP server is available while you have a lease with time left but the admin has set new information (like a reservation) then the computer will take the new lease.

When I am doing server migrations I will update DHCP scopes for things like new DNS servers and if users have difficulties I will often tell them to reboot. It's easier then walking them through the release/flushDNS/renew process.

Thanks, Ronnie. I wasn't seeing the option to "manage wireless networks" on my desktop pc. Well, the wireless NIC is disabled since I determined to get a more secure connection using Ethernet. But I found your description to be 100% right on for my Windows 7 laptop. Again, thanks.

Show notes for A+ 2.3, 2.4 and 2.5 are up and ready for viewing!

Michael,

I believe all of our new content will have the date added to end of each file. I'm not sure how that shows up on the links in the website but if you were to download the episodes to watch all of them should now have the date.

OK Nathan. Thanks.

Daniel Lowrie, our Host, told me this years ago. I can't forget it now that I've heard it.

All People Seem To Need Dan Physically.

The Hamachi guys were smart and resourceful. They needed a cheap and dirty way to create VPN connections on the public internet. They did not want to use RFC-1918 addresses as many routers on the live internet will just drop these packets. Also, they needed a system that for sure would not collide with any of the current IP Address assigned to any machine their users might install on.
History lesson: In the early days of the Internet, class A blocks were handed out all over the place. I know that Don talks about this in some of the shows. Pretty much anyone could get a class A block. Apple computer still owns the entire 17.0.0.0/8 address space to this day, and we gave up the entire 127.0.0.0/8 block just for loopback addresses. (I guess even computers love to hear themselves talk)
The Hamachi guys figured out that the class A network 5.0.0.0/8 had been assigned to someone but was not in use on the public internet -- so they essentially hijacked these addresses for their VPN service. At some point, the IANA pulled this block back and re-allocated it to a company called RIPE. This left Hamachi with a problem that they were going to have IP address conflicts, but they were able to search around and find another block of suitable addresses. It turns out that the 25.0.0.0/8 network was assigned to the British defense department, who does not just hang all of their systems off the public backbone with public IPs. So the 25.0.0.0/8 block is assigned but not in real use on the public internet. Hamachi switched from using 5.x.x.x addresses to using 25.x.x.x addresses a few years ago.
Hamachi also supports IPv6 addresses, which are available in bulk, but the above IPv4 hack is useful for people playing older LAN based games over a Hamachi VPN. If you are a fan of any of the old LAN games (Quake, UT, AOE, etc) then Hamachi is a way that you can play these with your friends without having to do the old LAN party.
Wikipedia of course has an entry on Hamachi, but if you are interested in more deep details then you can check out the Security Now guys at:

They have done a few deep dives into Hamachi in the past.
@Chris

Cool beans, thanks for the update.

Kyle,
We've moved to a different API. Overnight, we had a another issue with it as well but it should be restored now and functioning. If you're noticing the same issue or any other website issue please email support@itpro.tv
Thank you!
