Breaking Memory Free Of Compute With Gen-Z

Servers have become increasingly powerful in recent years, with more processing cores being added and accelerators like GPUs and field-programmable gate arrays (FPGAs) being added, and the amount of data that can be processed is growing rapidly.

However, a key problem has been the enabling interconnect technologies to keep pace with server evolution. It is a challenge that last year spawned the Gen-Z Consortium, a group founded by a dozen top-tier tech vendors including Hewlett Packard Enterprise, IBM, Dell EMC, AMD, Arm, and Cray that wanted to create the next-generation interconnect that can leverage existing tech while paving the way …

How to build command groups with sudo

When managing your /etc/sudoers files, it’s a good idea to organize user privileges in ways that make them easier to manage over the long haul and to assign permissions based on the roles that users play in your organization.One very useful way to do that is to group related commands together — such as all commands related to running backups or managing web sites — and assign them to the individuals or groups that require these privileges.Setting up command groups in /etc/sudoers To create a command group, you use what is called a Cmnd_Alias in your /etc/sudoers file and give the new command group a meaningful name. Here are some examples. Note that full pathnames should be specified for all of the commands included in a group. Otherwise, you are likely to see an error like this when you try to exit visudo. And remember to only edit /etc/sudoers with the visudo command to allow it to warn you in ways like this and prevent errors.To read this article in full, please click here

IDG Contributor Network: Could the smart city mean the death of privacy?

As the Internet of Things grows and society becomes more interconnected, millions of citizens are beginning to experience a new kind of lifestyle in smart cities. These futuristic, digitally-dependent cities aren’t entirely without their downsides, however; human rights activist, futurist, and private citizens are increasingly concerned that the advent of smart cities could mean the death of privacy itself.So, what’s the truth behind smart cities and privacy, and is all the craze generated over tomorrow’s urban centers anything more than wild speculation? A quick review of smart cities as they’re developing now shows that, managed properly, they can be a huge boon to the populace – but privacy advocates will have to stay on their toes.To read this article in full, please click here

What happens when an IoT implementation goes bad?

When talking about the Internet of Things, it’s important to remember that the “internet” part is just as critical as the “things.” That my sound cryptic, but it can have dramatic real-world implications, as demonstrated by the failure last week of one-time Kickstarter darling Emberlight.INSIDER: 5 ways to prepare for Internet of Things security threats The company had raised $300,000 back in 2014 to fund development of its smart light socket designed to work with ordinary bulbs. But on November 16, Emberlight notified customers it was going out of business due to competition from larger competitors and imitators selling similar devices for a quarter of the price.To read this article in full, please click here

Expanded Oracle Cloud Rains Down GPUs, Skylake Xeons

Oracle was late to the cloud game, but in recent years has moved aggressively to catch up. While still behind the top companies like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, Oracle is seeing gains in revenue and customers to its cloud environment, thanks in large part due to the hundreds of thousands of enterprise customers that use its various operating system, middleware, database, and application software.

The cloud revenue jump at Oracle is pretty steep. In a conference call discussing the most recent quarterly financial numbers, Oracle co-CEO Safra Catz noted that cloud revenue for the quarter …

Feedback: Ansible for Networking Engineers

Got this feedback on my Ansible for Networking Engineers webinar:

This webinar is very comprehensive compared to any other Ansible webinars available out there. Ivan does great job of mapping and using real life example which is directly related to daily tasks.

The Ansible online course is even better: it includes support, additional hands-on exercises, sample playbooks, case studies, and lab instructions.

However, Ansible is just a tool that shouldn’t be missing from your toolbox. If you need a bigger picture, consider the Building Network Automation Solutions online course (and register ASAP to save $700 with the Enthusiast ticket).

Route Filtering Techniques : Access-lists, Route-map and Distribution-lists


Today I am going to talk about the various route filtering method we are using in our network. These can be Access-Lists, Route-map, Distribution-list and Prefix-Lists. They are the excellent way to filter out the routes but the way we are implementing is different. Many of you are aware of the access list like standard, extended and so on. I already wrote an article on the access-lists. Please go through the below link for the access-lists

Back to Basics : Access-Lists and Types

Before we talk about these protocols,  I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos

But now if we are talking about all these route filtering protocol, we will take one by one to explain how and what they filter out in the network

IP Access List Route Filtering
So let's talk about the ACL or so called access-lists. An access-list is basically a mechanism accepting certain input from Continue reading

Unifi US-8 PoE Passthrough With The Cisco 3560CX

As part of my “everything should be on a UPS” strategy, I recently replaced a regular 8-port gigabit switch with a Ubiquiti Unifi US-8 Ethernet switch because the US-8 can be powered using POE (Power Over Ethernet) provided by a UPS-protected switch in my basement, so it should stay up in the event of a power outage. This also allowed me to indirectly provide UPS protection for the Ubiquiti wireless AP in that location because the US-8 has a PoE passthrough port with which I could power the AP. Clever, right?

Ubiquiti Unifi Us-8 with POE Passthrough

 

POE Passthrough

To clarify (because a picture is worth many thousands of my words), here’s how things were:

Before the Unifi US-8

And here’s how things are after installing the Ubiquiti Unifi US-8:

After the Unifi US-8 with POE Passthrough

The new setup worked well, but I noticed after a few days that the uptime for the Unifi US-8 kept on resetting; that is, it appeared to be rebooting. The Cisco 3560CX switch which is providing the POE can supply 30W per port, which is plenty enough for the US-8 and the wireless AP to be daisy-chained like this, yet when I looked at the logs on the 3560CX, I found an error:

HPE broadens its processor offerings with AMD, Cavium systems

It’s been said that the industry dislikes too many choices, but HPE is offering more choices for server products with new ARM- and AMD Epyc-based servers. And in both cases, HPE is touting price-performance efficiency.The company today announced new ProLiant DL385 Gen10 servers running AMD’s Epyc processor, the server version of its Zen-based core that has shot the company back into serious competitiveness with Intel.Also on Network World: REVIEW: How rack servers from HPE, Dell and IBM stack up HPE claims that with the Epyc chips, customers can have more virtual machines per server and the ability to process more data in parallel, thanks to the 32 cores with two threads per core in the Epyc processor. The result, it says, is up to 50 percent lower cost per virtual machine than “traditional” servers.To read this article in full, please click here

Certifications: Why I Like Them, How I Use Them and My Plan for Security Learning

The other day Daniel Dib (http://lostintransit.se) asked me an interview question.  The question was about certifications.  What do I think about them…. and are they losing their “value”.

Poor certifications.  People question their value.  Of course “value” typically means for many what can the cert “do” for you once you have it.  People also get so judgemental of others for “collecting” them.  And yes… when I was younger I was, admittedly, one of those people who looked down on people I viewed as “cert collectors”.  Poor poor certifications.  In every area certifications exist they can get a bad rep.  IT industry, Scuba Diving, .. heck even in girl scouts when there was always that one girl who wanted to try to get every possible girl scout badge.  ?

Why I Like Them and How I Use Them

In 2012 my view on certs changed.  I realized I could use them to my advantage to help me organize my learning by making goals and signing up for certs.   You see, back in 2010 I had bought a few books about Wireshark by Laura Chappel and told myself I would make Continue reading
