The fight over a new Wi-Fi channel is coming to a head

Globalstar’s plan to open a new Wi-Fi channel under its control is nearing the moment of truth after years of regulatory wrangling.The U.S. Federal Communications Commission is considering Globalstar’s plan, and a vote could come at any time. News reports suggest it might be close.If Globalstar gets its way, Wi-Fi users in the U.S. will have one more channel, which could reduce congestion and improve performance. But both their mobile devices and the hotspots they use would need firmware upgrades to take advantage of the new frequency, and the channel wouldn’t necessarily be open to everyone.To read this article in full or to leave a comment, please click here

How to build a network of Linux routers using quagga

This post lists the commands required on each node to build a network of three Ubuntu Linux routers. Each router is connected to the other two routers and is running quagga. Each router is also connected to a PC running Ubuntu Linux.

I use this network configuration to evaluate network emulators and open-source networking software in a simple scenario. Readers may find these commands useful in building their own configuration scripts.

I provide “copy and paste” commands so the network can be configured quickly.

Creating a basic topology

The physical — or virtual — network installation and the management network setup is outside the scope of this post. The method used to build the lab topology depends on the equipment, and/or the network emulator and hypervisor technology you are using.

I assume you already have six machines running and connected in a network as shown above, and I assume you have a management network set up so that each machine can communicate with the host computer and with the Internet.

Router configuration

Each router needs to install the quagga router package, configure quagga, and then configure the network using the quagga VTY shell. Optionally, quagga daemon configuration files may be Continue reading

5 things you should know about password managers

That’s why password managers exist. Here’s why they’re important, and how to get the most out of them.To read this article in full or to leave a comment, please click here

Apple explains why iMessage isn’t coming to Android

Ahead of Apple's WWDC keynote this year, one of the more bizarre and sketchy rumors we saw take shape claimed that Apple was planning to deliver iMessage to Android. As is typically the case, the rumor mill took this somewhat ridiculous rumor and ran with it.+ Also on Network World: A closer look at Apple’s biggest announcements from WWDC 2016 +The only problem is that some people were so busy trying to figure out the ramifications of iMessage hitting Android that they didn't take a step back and try to figure out if this is something Apple would even contemplate in the first place. Remember, every move Apple makes is strategic and geared towards making more money, either via device sales or software. That being the case, iMessage on Android would not only be a free app, but it would also eliminate a user-experience advantage of iOS.To read this article in full or to leave a comment, please click here

Is the ‘secret’ chip in Intel CPUs really that dangerous?

An article on Boing Boing is stirring up fears that Intel x86 processors have a secret control mechanism that no one is allowed to audit or examine, so consequently, this could expose systems to unkillable, undetectable rootkit attacks. In an article that is equal parts technical and fear-inducing, Damien Zammit is up front about his goal. He declared he had made it his mission to get Intel to replace this system with a free, open source replacement "before it's too late."+ Also on Network World: Intel declares independence from the PC +To read this article in full or to leave a comment, please click here
