How the Orlando airport went fully wireless

If you're reading this post, you're most likely involved in the technology industry in some way. As such, you probably attend at least one, if not multiple, events in Orlando every year. It's only May and I think I've been there four times already this year.In addition to being one of THE places to go for technology conferences, it happens to be one of the country's top vacation spots for families. This makes the Orlando airport unique in that it's a high-volume origin and destination airports. Most of the country's busy airports, like Dallas-Fort Worth, Chicago and Atlanta, are airline hub locations, so a high percentage of the passengers are connecting from one flight to another. However, with Orlando, almost all of the passengers are either coming to or departing from the local area.To read this article in full or to leave a comment, please click here

Own the Problem

rpteamIn the late 1990’s, I was on the routing protocols TAC team in Raleigh — which means I answered the phone, and said things like, “This is Russ from Cisco TAC, how can I help you?” Generally what followed was a crash, or, well, just about anything. The design on the left is what we had on the back of our shirts — including what we called ourselves, the Gateway of Last Resort.

Of course it’s a play on words, as you might imagine — where does a host send traffic it doesn’t know what to do with? The gateway of last resort. And what is the gateway of last resort? A router. And what the RP team worked on was, well, routers. But there’s another reason we adopted this slogan for ourselves — because it was, generally speaking, how the CRC (the folks who took the initial call and figured out which backline team to hand it off to) conceived of our little team. The PIX, the 7200, VIP cards, crashes, hangs, tracebacks, any sort of routing protocol problem, lots of hardware problems, anything to do with the forwarding path, memory fragmentation, and just about anything else.

Walking with Packets: Traceroute Through MPLS Cloud

Think about this for a minute: An MPLS network with a two Provider Edge (PE) routers and some Provider (P) routers. The P routers have no VRFs configured on them and therefore have no routes whatsoever for any of the customer networks. A customer then does a traceroute from one of their sites, across the MPLS cloud, and into one of their other sites. The traceroute output shows the P routers as hops along the path.

How is it possible for the P routers to reply to the traceroute if they don’t have routes back to the customer network?

The Lab Setup

Here’s the network:

MPLS-Traceroute-Topo

Here’s the traceroute output from R21’s loopback0 to R8’s loopback0 (the last octet of each IP address corresponds to the name of each router):

Researchers play cat and mouse with Google’s anti-phishing Chrome extension

For the past several days security researchers have raced to demonstrate that phishing protections added by a new Google Chrome extension can be bypassed with ease.The Password Alert extension, developed by Google and released Wednesday, is designed to alert Chrome users when they input their Gmail passwords on websites that don’t belong to Google and are therefore part of phishing attacks.By Thursday, an information security consultant named Paul Moore had already devised a method that attackers could use to block the extension’s alerts.To read this article in full or to leave a comment, please click here

The Upload: Your tech news briefing for Monday, May 4

Facebook opens Internet.org platform to (almost) any content serviceStung by criticism that its Internet.org platform is a closed-off, private web masquerading as a philanthropic effort to bridge the digital divide, Facebook is opening the service to developers who meet its technical guidelines. CEO Mark Zuckerberg said in a video that although the company started with just a few content partners, “we’ll work with anyone who wants to join us.” Facebook posted a version of the video subtitled in Hindi, aiming to reach its audience in India where the company was seen by some as trampling principles of net neutrality with Internet.org.To read this article in full or to leave a comment, please click here
