Cisco launches Network Academy Advantage

I haven’t seen Cisco officially announce it on the Network Academy Headlines, but the new NetAcad Advantage website is up. It’s aimed at anyone who’s completed the Cisco Network Academy courses and is looking to further their career and take advantage of their new skills.

This should be great for all the Academy regions that currently don’t have a proper Career Connection portal (The UK included) . I’ve been waiting and pushing for something like this for over a year now; and it’s great that Cisco is taking care of its students.

I’m looking forward to seeing how the site progresses and grows. Who knows, maybe they’ll ask the author of the excellent Career Builder’s Toolkit, Matt Moran, to contribute? 🙂

Cracking WEP with AirPcap and Cain and Abel

This video tutorial demonstrates how to crack WEP in Windows using AirPcap and Cain and Abel.

Preparation

You’ll need:

Note: It is possible to get this working by using the cheaper “Classic” AirPcap, in conjunction with the old 2.0 Beta Tx Drivers for AirPcap, to enable packet injection capability, but this is entirely unsupported, and is not guaranteed to work. YMMV.

Notes

  • To begin ARP injections, AirPcap must capture at least 1 ARP request from a system on the target AP. You can usually force this by sending a Deauth to a connected client.
  • Make sure you have over 250,000 IVs before attempting to crack the WEP key.
  • In my tests, the old AirPcap (silver-grey) appears to perform significantly faster than the new AirPcap (dark-grey). I think it’s about 10x faster.

Windows XP: Missing Authentication tab

If you’re setting up 802.1x on your Network connection but can’t see the Authentication tab, make sure the “Wireless Zero Configuration” service is running.

  1. Start > Run… > services.msc
  2. Find the Wireless Zero Configuration service.
  3. Right click on it, and choose “Start”.

The Authentication tab will then appear on your Network connection properties.

Yes, I know. But apparently, to get 802.1x support, you need to enable a Wireless service, even though you may well be using it on a wired connection. Intuitive, eh?

Cisco and WiMax

After watching a brief overview of WiMax on ZDnet which touched on Mobile WiMax, I wondered what Cisco might have in the pipeline regarding services orientated around WiMax and, in particular, Mobile WiMax.

Fixed WiMax Potential

Cisco already make point-to-point Wi-Fi bridges that, with a dish and some breaking of the 802.11 spec, can go very far. For 2.4Ghz, potential figures of up to 11mbps over 11.5 miles (18.5km). For 5Ghz, the figures are around 54mbps over 12 miles (19km).

WiMax should be able to beat that distance and speed, and more reliably, too. Because WiMax doesn’t have to operate in the unlicenced band, WiMax could help eliminate the current issue of saturated Wi-Fi frequencies in urban areas.

I am ignoring the glaring price issue; A point-to-point WiMax solutions would probably be prohibitively expensive in comparison to a Wi-Fi solution. Hopefully, as with Wi-Fi , the prices will rapidly fall as more people adopt the technology.

Mobile applications of WiMax

Recently, Nokia and Motorola announced they will ship WiMax support in some of their Mobile Equipment in 2008. With Intel firmly behind WiMax, this means that both Cellular Phones and Laptops will eventually ship with WiMax as standard; much the same as almost every Phone ships with Bluetooth and every laptop seems to ship with Wi-Fi nowadays.

Maybe Cisco will develop a Unified Communications client for the Symbian OS? Seems they already have, along with a bunch of other Mobile platforms. Mobile WiMax access to your company’s VPN at true broadband speeds would be amazing. Not to mention the cost benefits of redirecting voice over WiMax and Wi-Fi networks, particularly for international calls.

Plugged in your USB Flash drive but Windows can’t see it?

You’ve probably run into a drive lettering conflict.

Possible Symptoms

  • At home, your PC sees your flash drive as drive letter E. (I’m using E as an example)
  • You go to work and plug in your USB stick, but it doesn’t show up.

The likely culprit

This is probably because your PC at work already has a Drive E assigned – Windows can’t have two drives with the same drive letter, so your Flash drive can’t be used. To use it, we need to change the drive letter assigned to the flash stick.

How to fix it

  1. Right click on My Computer.
  2. Click ‘Manage’.
  3. Click ‘Disk Management’ in the Left pane.
  4. Locate your flash stick in the right pane.
  5. Right click on it, and choose ‘Change Drive Letter and Paths…’.
  6. Click either Change or Add, and assign the drive a new letter. (I usually pick something high up the alphabet, like ‘R’)
  7. Ta-da! Your Flash drive should now appear 🙂
