Collection of useful, relevant or inane places on the the Internets for 30 Mar 11:
- Aerohive Networks, Inc. | Events | Aerohive at Wireless Field Day – Aerohive have posted the presentations from the Tech Field Day. Given that they are pursuing a different technology approach from other wireless companies, you might want to watch to understand how their controller-less architecture works. This isn’t marketing / PR, it’s real information like you were in the room for a sales call and delegates call them out on the crap from time to time. That’s what it different about this.
- HP Blogs – How to make the most of cool & fast new Wi-Fi tech… – The HP Blog Hub –
Provided the SSID is available on both bands, it will ignore or refuse requests to connect to the 2.4GHz radio as long as it knows the client will be able to connect with a good signal to the 5GHz radio.
- Open Networking Foundation ª Blog Archive ª Open Networking Foundation Formed to Speed Network Innovation –
The initial members (including founding companies) of ONF are: Broadcom, Brocade, Ciena, Cisco, Citrix, Dell, Deutsche Telekom, Ericsson, Facebook, Force10, Google, HP, IBM, Juniper Networks, Marvell, Microsoft, NEC, Netgear, NTT, Riverbed Technology, Verizon, VMware, and Yahoo!.
Who is involved to do something, and who is involved to “keep an eye on what happens”. If it’s a closed process, how do we know if companies are blocking progress because it suits them ?
- Who said 5GHz was ëcleaní? 🙂 ´ SC-WiFi –
At this point, I started to suspect my Spectrum Analyzer since I was using a non-Cisco branded Spectrum Analyzer card with the Cisco Spectrum Expert software (the card I was using had the Cognio components that Cisco purchased and re-branded as their own). So I grabbed a copy of the card manufacturers software to rule out in compatibility and I got the same results.
SpecAn tools can give unreliable results when using off list hardware.
Always test your tools and keep them in good working order
Donít assume that your tools are telling you the truth. If you see something suspect, dig into it and validate against another source
Learning about wireless networking is hard. Learning about tools is hard too, and the tools are the only way to ‘see’ wireless networks. Gotta have them.
- Cisco Catalyst Switch Guide 2011 – One of the few occasions when many departments (sorry, business unit) actually cooperate to produce information that the customers can actually use. And the only performance information that appears to be available for most switches in Cisco’s product line. Don’t leave it in the cloud, save it to your hard drive because the earlier version with all the older information is now gone.
- EOS/EOL for the Cisco CSS 11500 Series Content Services Switches† [Cisco CSS 11500 Series Content Services Switches] – Cisco Systems –
The date the document that announces the end of sale and end of life of a product is distributed to the general public.

I didn’t know Cisco was still stilling these relics of a bygone age. Talk about extracting a profit from existing products. And lets not talk about customers silly enough to buy them.
- The Mac Security Blog ª Protect Safari from Fraudulent Digital Certificates – By default OSX Safari does not have OSCP enabled to check for revoked certificates. And while OSCP isn’t much of a protocol and much reviled, you should enabled it now. Here’s how.
Safari, however, doesnít directly use the CRL or OCSP systems mentioned above; settings to activate this feature are found in Keychain Access. To do this, open Keychain Access; it is in the Utilities Folder in the Applications folder on a Mac. Choose Keychain Access > Preferences, then click on the Certificates tab. Set the first two options, for OCSP and CRL, to Best Attempt, and leave priority set to OCSP. This will tell Safari, or any other program that uses the built-in certificates on Mac OS X, to check these servers before accepting any SSL certificate on a web site.
- Why HuffPoís British Empire Dreams Could Fall Flat: Tech News and Analysis ´ –
Meanwhile the British print and web news market ó the area which proved the biggest gap for Huffingtonís brand of news in the U.S. ó is radically more competitive than Americaís. Britainís biggest non-tabloid newspaper, the Daily Mail, sells more copies every day in a nation of 61 million than USA Today manages to shift across the entire 52 states. The rest of the market is similarly inflated by comparison: on a per capita basis, the New York Times is smaller than every single one of Britainís 11 nationally-available newspapers.
Surprising statistics. Also highlights that potentially the British IT market is probably very different from the US. Food for thought.
