FlexVPN QoS

This post will cover several most common QoS configuration techniques for Multipoint VPNs. Focus will be on FlexVPN DMVPN, however most of the conclusions will be applicable to the traditional DMVPN as well. Assumptions Most of the FlexVPN and DMVPN deployments use Internet as a WAN transport. This creates a very unique set of requirements […]

What the Dell, EMC merger really means

Despite its whopping price tag, the $67 billion Dell acquisition of EMC doesn't radically reshape the technology market. The acquisition, announced today, is not as disruptive to the tech market as, say, Oracle's purchase of Sun Microsystems, or Hewlett-Packard's acquisition of Digital Equipment Corp., companies with competitive platforms and technologies.To read this article in full or to leave a comment, please click here

Fake LinkedIn profiles lure unsuspecting users

No doubt you've received a LinkedIn invition from someone you don't know -- or you're not sure you know. Next time, you might want to think a little harder before accepting. Researchers from Dell SecureWorks Counter Threat Unit have identified a network of at least 25 well-developed LinkedIn profiles as part of a targeted social engineering campaign against individuals in the Middle East, North Africa, and South Asia. The fake profiles were linked to 204 legitimate profiles belonging to individuals working in defense, telecommunications, government, and utility sectors. A quarter of the victims worked in the telecommunications sector in the Middle East and North Africa. Fortunately, the fake profiles have already been removed from LinkedIn.To read this article in full or to leave a comment, please click here

CCNA – Operation of IP Data Networks 1.1

We kick off the CCNA series from the beginning. Operation of IP data networks is weighted as 5% in the CCNA RS blueprint. The first topic is:

1.1 Recognize the purpose and functions of various network devices such as routers, switches, bridges and hubs

Router

A router is a device that routes between different networks, meaning that it looks at the IP header and more specifically the destination IP of a packet to do forwarding. It uses a routing table which is populated by static routes and routes from dynamic protocols such as RIP, EIGRP, OSPF, ISIS and BGP. These routes are inserted into the Routing Information Base (RIB). The routes from different sources compete against each other and the best route gets inserted into the RIB. To define how trustworthy a route is, there is a metric called Administrative Distance (AD). These are some of the common AD values:

0          Connected route
1          Static route
20         External BGP
90         EIGRP
110        OSPF
115        ISIS
120        RIP
200        Internal BGP
255        Don't install

If a value of 255 is used, the route will not installed in the RIB as the route is deemed not trustworthy at all.

Judge does not order Apple to disable security on encrypted device

Well, well, well…a federal magistrate of the U.S. District Court for the Eastern District of New York has so far refused to order Apple to disable security on a customer’s encrypted mobile device even though the government assured the judge that doing so “is not likely to place any unreasonable burden on Apple.”According to the court document (pdf), available on Cryptome which recently admitted to a leaking users’ IP addresses in a separate tech drama, the government filed a sealed application on Oct. 8; it asked the court “to issue an order pursuant to the All Writs Act,” and thereby force Apple “to assist in the execution of a federal search warrant by disabling the security of an Apple device that the government has lawfully seized pursuant to a warrant issued by this court. Law enforcement agents have discovered the device to be locked, and have tried and failed to bypass the lock.”To read this article in full or to leave a comment, please click here

HP and SanDisk join forces to create storage 1000x faster than NAND flash

HP and SanDisk are plotting new storage technology that could be 1,000 times faster than flash memory, though they’ll face some competition along the way.Details on the new technology are scarce, but the goal is to create a “universal memory” that serves as both long-term storage and RAM, the Wall Street Journal reports. The goal is to commercialize this technology some time between 2018 and 2020.Why this matters: Today’s computers offer RAM and storage separately, because the former is much more expensive and purges its data when the machine powers down. Programs and files are stored on flash memory, but during use they’ll load some data into RAM for faster short-term access. A single type of memory for both short- and long-term storage could boost a PC’s performance dramatically.To read this article in full or to leave a comment, please click here

As a private company, Dell-EMC will enjoy a freedom HP can only dream of

Dell's US$67 billion acquisition of EMC will give it access to a sales force notorious for its ability to "sell ice to eskimos," while EMC will gain a new foothold among mid-market customers. As a private entity, the combined result will face a freedom from market pressures that competitors such as HP can only dream of.Those are just some of the benefits that could follow from the deal announced early on Monday."This industry is undergoing a fundamental transformation," said Crawford del Prete, an executive vice president with IDC. "You can't navigate it with short-term business decisions."To read this article in full or to leave a comment, please click here

California governor vetoes bill punishing irresponsible drone users

After several incidents where irresponsible drone users interfered with firefighting planes, California looked poised to pass harsher penalties for the idiots who were endangering the planes. It seemed a no-brainer. Well, Governor Jerry Brown doesn't seem to have a brain.In three days, he signed a climate change bill, a gender pay equity law, a bill to combat racial profiling, and one legalizing assisted suicide. But he vetoed three bills that would have prohibited civilians from flying aerial drones over wildfires, schools, prisons, and jails.To read this article in full or to leave a comment, please click here

What Dell buying EMC means for VMware

With Dell acquiring EMC for a record $67 billion, it raises the question: What does this all mean for VMware and its customers?Officially, Dell says VMware will remain an independent publicly traded company. The wrinkle is that EMC owns 83% of VMware’s stock; and Dell is acquiring EMC.Forrester analyst Glenn O’Donnell says he expects the impact of the merger on VMware customers to be minimal. “You can basically look at this as some musical chairs at the high end,” he says. But other analysts say there could be significant opportunities for Dell to combine its hardware with VMware’s software.+MORE AT NETWORK WORLD: Dell acquires EMC for $67 billion | VMware CEO hits on network virtualization reality, feuding with Cisco & the EMC Federation's future +To read this article in full or to leave a comment, please click here

Worth Reading: Hybrid Infrastructure

Although industry experts anticipate a 44 percent annual growth in cloud-based workloads over the next several years, the reality is that despite rapid cloud adoption, many businesses will continue to have a significant part of their daily operations tied to physical infrastructure and its processes for many years to come. The Cloud is for everyone, but not for everything. — via the data center journal

Google’s OnHub turns out to be part router, part Chromium OS computer

While Google cheerily advertises the 13 antennas packed into its new OnHub router, the company’s been less forthcoming about the software under the hood. Now that some hackers have rooted the high-tech Wi-Fi router, we have some clarity: OnHub appears to run a heavily-modified version of Chromium OS, the same browser-based software that powers Chromebook laptops and Chromebox desktops. The root method for OnHub first appeared on Exploitee.rs. It turns out that the router’s underside contains a hidden switch underneath one of its screws. This switch can boot OnHub into developer mode if you enter a specific keystroke, using a keyboard plugged into the router’s USB port. That keystroke is Ctrl + D, which is precisely what you’d use to enter developer mode in Chromium OS.To read this article in full or to leave a comment, please click here

Why Verizon’s ‘zombie cookies’ are scarier than ever

Like the Walking Dead lurching across your TV screen, Verizon's "zombie cookies" never give up. These hard-to-kill bits of code that track your mobile surfing habits are about to be shared with Verizon's newest acquisition, AOL, and that means additional advertisers will learn even more about you.Beginning in November, if you access the Web via Verizon’'s network, data on "your gender, age range and interests," (according to a Verizon FAQ page on its Relevant Mobile Advertising program) will be pushed to AOL's extensive network of advertisers.To read this article in full or to leave a comment, please click here
