When HPC Becomes Normal

Sometimes, it seems that people are of two minds about high performance computing. They want it to be special and distinct from the rest of the broader IT market, and at the same time they want the distributed simulation and modeling workloads that have for decades been the most exotic things around to be so heavily democratized that they become pervasive. Democratized. Normal.

We are probably a few years off from HPC reaching this status, but this is one of the goals that the new HPC team at Dell has firmly in mind as the world’s second largest system maker …

FBI chief says Guccifer lied about hacking into Clinton’s email server

A Romanian hacker's claim that he broke into Hillary Clinton's private email server in 2013 was a lie, according to the FBI. Marcel Lehel Lazar, also known as Guccifer, has boasted about the breach to various media outlets, saying in May that it had been "easy."But on Thursday, FBI director James Comey said that Lazar, who is now in U.S. custody, has admitted the claim was false."He admitted that was a lie," Comey said during a congressional hearing on Clinton's use of her own private email server.Lazar, originally from Romania, was extradited to the U.S. and is awaiting sentencing for breaking into the email and social media accounts of various U.S. officials as well as a member of the Bush family.To read this article in full or to leave a comment, please click here

Understanding ‘transport output’ and ‘access-class’

Several years ago I wrote an article called The Elusive “access-class out” Command. My primary goal was to help CCNA students understand both the behavior of and placement of this command. My friend Anthony Sequeira done a great job in the video that is also shown in my original post. Today, I want to share another command and expand on there behavior.

For all of the demonstrations in this article, the following topology will be used. The router named iosv-2 will be the primary focus and the only place changes will be made.

Topology

Backing up for a moment, there are a couple of messages that might be displayed when an IOS device blocks outbound telnet or ssh sessions from the current exec session. These are demonstrated with a quick configuration of an transport output and access-class restriction.

//the first error is unique depending on
//if ssh or telnet is being used
iosv-2(config)line con 0
iosv-2(config-line)#transport output none
iosv-2(config-line)#do telnet 192.168.0.3
% telnet connections not permitted from this terminal
iosv-2(config-line)#do ssh -l cisco 192.168.0.3
% ssh connections not permitted from this terminal

//now we can re-enable all the protocols
//and demonstrate the other error message
iosv-2(config-line)#transport input all
iosv-2(config-line)#access-list  Continue reading

Wendy’s hack was bigger than thought and exposed credit card data

A data breach that hit Wendy's fast food restaurants was more than three times bigger than originally disclosed and exposed customer credit card data.The company said Thursday that malware installed in point-of-sale systems was discovered at over 1,000 of its franchised U.S. restaurants -- a big jump from the "fewer than 300 stores" it said in May had been affected.Hackers gained access to the machines using remote access credentials of a third-party service provider, Wendy’s said.The breach began in fall 2015 and wasn't discovered until early this year.

6 ‘data’ buzzwords you need to understand

Take one major trend spanning the business and technology worlds, add countless vendors and consultants hoping to cash in, and what do you get? A whole lot of buzzwords with unclear definitions.In the world of big data, the surrounding hype has spawned a brand-new lingo. Need a little clarity? Read on for a glossary of sorts highlighting some of the main data types you should understand.1. Fast data The shining star in this constellation of terms is "fast data," which is popping up with increasing frequency. It refers to "data whose utility is going to decline over time," said Tony Baer, a principal analyst at Ovum who says he coined the term back in 2012.To read this article in full or to leave a comment, please click here

Worth Reading: Independence from L2 data centers

We’ve all been there. That “non-disruptive” maintenance window that should “only be a blip”. You sit down at the terminal at 10pm expecting that adding a new server to the MLAG domain or upgrading a single switch will be a simple process, only to lose the rack of dual-attached servers and spend the rest of your Thursday night frantically trying to bring the cluster back online. If I never spend another evening troubleshooting an outage caused by MLAG, I’ll die happy! -Cumulus

FTC warning: The IRS does not accept payment in iTunes cards

The Federal Trade Commission issued a warning today about a scam that sounds ridiculous but is nonetheless surprisingly common: Con artists are convincing victims that they’re from the IRS and will accept outstanding payments in the form of iTunes cards.From an FTC blog post: People have told the FTC about scammers who called and demanded iTunes cards as “payment.” Bogus “IRS agents” told people they owed back taxes and would be arrested soon, unless they bought an iTunes card and gave the code to the “agent.” Phony “government grant” officers called and promised a big payout, after the person bought an iTunes card and read the code to the “grant officer.” Other fraudsters told people their grandkids were in jail and the only way to help was — you guessed it — to buy an iTunes card and read the code over the phone. All the stories were false.To read this article in full or to leave a comment, please click here

NetBox v1.1.0 Released

One year ago today, I made the first commit to a repository named "netbox" hosted internally at DigitalOcean. It was the first iteration of a tiny little app I scratched together using the Django Python framework to track IP prefix utilization. A year later, NetBox has grown into an extensive tool that we use to track IPs, racks, devices, connections, circuits, and even encrypted credentials. And I'm happy to say that it's now open source!

4 tips for buying cloud management software

Managing clouds can be a challenge given that virtual machines and storage are running in two different environments simultaneously. A crowded industry of cloud management platforms (CMP) has emerged to help.Gartner Research Director Mindy Cancila says the CMP market is young and maturing; customers should understand the limitations of various options.Here are four tips from Cancila for organizations considering cloud management products.IaaS needs its own tools Many organizations began their cloud journey by using SaaS tools like Office 365, Salesforce or some other business planning software. These SaaS platforms may require some new skills, but customers don’t usually need to purchase a whole new management platform to use them. Infrastructure as a Service (IaaS) is different. Consuming cloud-based virtual machines, storage, databases and other services is such a complex issue that Cancila says users can benefit greatly from using a dedicated management platform for IaaS, especially if they’re managing a hybrid cloud computing environment.To read this article in full or to leave a comment, please click here
