Basics on Cisco DSL Router Configuration

Today I am going to talk about the DSL router basics and the configuration of the Cisco DSL router. People who are from the Routing and Switching background should have this as a basics level of learning. You can connect Cisco DSL router with the PC. A console connection is made with a rolled cable and connects the console port of the Cisco Digital Subscriber Line (DSL) Router to a COM port on a PC. The console cable that is included with the Cisco DSL Router is a flat light blue cable. 

For more information on the pin outs of a rolled cable, or the pin outs of an RJ−45 to DB9 converter, see Cabling Guide for Console and AUX Ports.
  • Connect the RJ−45 connector on one end of a Cisco console cable to the console port of the Cisco DSL Router.
  • Connect the RJ−45 connector at the other end of the console cable to an RJ−45 to DB9 converter.
  • Connect the DB9 connector to an open COM port on your PC.

Now Lets talk about how to set up the basic configurations on the above mentioned Cisco DSL router in Continue reading

How network automation can speed deployments and improve security

Five years ago, IT was decentralized at the University of New Mexico. “Every school or college had their own IT, and in most cases they were completely under-resourced – a one-person shop having to do phones, apps, email, desktop, servers, storage, disaster recovery, all of that,” said Brian Pietrewicz, deputy CIO at University of New Mexico.The university transitioned to a self-service model that enables each of its more than 100 departments to deploy infrastructure and application services itself and have them managed by the now-centralized IT team.Adopting VMware’s vCloud Automation Center enabled departments to consume cloud resources, but also give the management team the ability to curtail that consumption if necessary.To read this article in full or to leave a comment, please click here

VMware adds whitelist security to the hypervisor

Overlooked in the hoopla around the VMworld conference was an announcement of the availability of AppDefense, a new product that lets companies restrict the types of operations applications are allowed to run on virtualized servers. AppDefense works with the VMware hypervisor and can also connect to third-party provisioning, configuration management and workflow automation platforms. It can send out alerts, quarantine apps, shut them down and even restore a VM from an image. All of this is based on AppDefense catching unusual behavior, such as trying to modify the kernel or communicate with an unrecognized remote server. VMware already has some security features built into its NSX and VSAN products, but those are around networking and storage. AppDefense secures the core virtual machines in vSphere itself. It does this by using behavior-based whitelisting, which is not easy to do on desktops because they run a lot of apps. But on a server, especially a virtual server, it’s a much easier proposition. In some cases, virtual servers run only one or two apps, so shutting out everything else is simple.To read this article in full or to leave a comment, please click here

Will Ransomware Die?

Ransomware has been one of the more prevalent security topics for past few years. Some probably think this form of digital destruction is here for the long haul. While this may be an accurate prediction, I can imagine a turn of events that would end this form of attack. To be clear, my theory is not that enterprise networks will plug every possible entry point. My prediction is that the ransomware business model COULD cease to be viable.

Let me expand on my position. For a business model to work, it has to have a monetization strategy. For ransomware, that strategy includes the victim sending money (typically bitcoin) to the attacker—trusting that they will be given the keys to decrypt their files. In this model, the victim has to trust their attacker [to do the right thing]. In and of itself, that seems to be an oxymoron and a plea in desperation.

So if these types of attacks fail to produce recovery options and gain widespread coverage, this trust is further eroded. To some degree this has already happened with Nyetya.

IDG Contributor Network: Why hybrid cloud is the future of enterprise IT

As cloud computing continues to generate a huge amount of buzz and interest over its future, another phenomenon is gaining investor’s and developer’s interest with promises to upend the future of enterprise IT. Hybrid cloud tech, which has only recently come into its own, is increasingly being recognized as the cash-cow of the future. But what exactly is this tech, and is it worth all the hubbub it’s garnered?A quick look at today’s hybrid cloud tech shows that the attention it’s drawn to itself is entirely warranted; the idea behind it may not be new, but recent advancements in computing have enabled it to truly thrive in the marketplace for the first time, and it could very well be on the verge of redefining modern computing.

What’s So Bad About POSIX I/O?

POSIX I/O is almost universally agreed to be one of the most significant limitations standing in the way of I/O performance exascale system designs push 100,000 client nodes.

The desire to kill off POSIX I/O is a commonly beaten drum among high-performance computing experts, and a variety of new approaches—ranging from I/O forwarding layers, user-space I/O stacks, and completely new I/O interfaces—are bandied about as remedies to the impending exascale I/O crisis.

However, it is much less common to hear exactly why POSIX I/O is so detrimental to scalability and performance, and what needs to change to have a suitably …

Declarative and Imperative Automation Thinking

Event driven or workflow driven automation for the uninitiated can appear daunting. With the rise of machine learning which adds more complexity to our field, simple rule driven automation feels more in reach than it ever has. This post aims to introduce you to a viewing lens for the world of great automation.

Converting processes in to workflows can be a tough task to accomplish and whilst this is relevant, it isn’t for this post. That’s one for another day but a great talking point and one that will be addressed.

The Layer Cake

Good automation tooling offers two views of the world; one high level that you pass arbitrary data around and one that handles interface implementation, which converts the arbitrary data to meaningful contextual data. In other words, a declarative and an imperative view, the ‘what’ and the ‘how’. The dimension that exists between the two can make or break the tool. If we have to care too much about how data is passed from one layer to the other, we’re not users, we’re more co-developers and it’s a kit not a tool.

Our Layer Cake model is simple at a high level. Two layers are enough to Continue reading

Private cloud use grows, and ZeroStack wants to help spin them up

In June, private cloud infrastructure provider ZeroStack hired David Greene as its new CEO. For those of you who have followed the networking space closely, you may recognize Greene as the chief marketing officer of a couple of companies that were pioneers in their respective industries. Most recently, he was at Aerohive, one of the first Wi-Fi vendors to embrace a completely controller-less model.Prior to that, Greene was CMO of Riverbed. Riverbed certainly wasn’t the first WAN optimization vendor, but the company was responsible for evangelizing it and making it a household term (at least among IT circles).+ Also on Network World: Public vs. private cloud: Why the public cloud is a real threat to security + Now, Greene is trying to catch another wave, as ZeroStack is one of the first companies to offer an easy-to-deploy solution that enables businesses to quickly deploy a private cloud.To read this article in full or to leave a comment, please click here
