Repeated failed login attempts on a Linux server can indicate that someone is trying to break into an account or might only mean that someone forgot their password or is mistyping it. In this post, we look at how you can check for failed login attempts and check your system's settings to see when accounts will be locked to deal with the problem.One of the first things you need to know is how to check if logins are failing. The command below looks for indications of failed logins in the /var/log/auth.log file used on Ubuntu and related systems.

The edge is being sold to enterprise customers from just about every part of the technology industry, and there’s not always a bright dividing line between “public” options – edge computing sold as a service, with a vendor handling operational data directly – and “private” ones, where a company implements an edge architecture by itself.There are advantages and challenges to either option, and which is the right edge-computing choice for any particular organization depends on their individual needs, budgets and staffing, among other factors. Here are some considerations.To read this article in full, please click here
The community around the open-sourced Software for Open Networking in the Cloud (SONiC) NOS got a little stronger as Apstra says its intent-based networking software is now more ready for enterprise prime-time than implementations from Cisco and Arista.The Linux-based NOS, developed and open sourced by Microsoft in 2017, decouples network software from the underlying hardware and lets it run on switches and ASICs from multiple vendors while supporting a full suite of network features such as border gateway protocol (BGP), remote direct memory access (RDMA), QoS, and other Ethernet/IP technologies.To read this article in full, please click here
Nearly 70% of the 500 fastests supercomputers in the world as announced at the Supercomputing 20 conference this week are powered by Nvidia, including eight of the top 10.Among them was one named Selene that Nvidia built itself and that debuted at Number 5 on the semi-annual TOP500 list of the fastest machines. With top-end systems requiring 10,000 or more CPUs and GPUs, they are enormously expensive, so government or research institutions own the majority of them.That makes Selene all the more rare. It was built by and is based at Nvidia's Santa Clara, California, headquarters. (It’s widely believed there are many supercomputers in private industry that are not reported for competitive reasons.)To read this article in full, please click here

The HAP aircraft system, as envisaged, would beam its Internet from the stratosphere, which is the second major layer of Earth's atmosphere. The aircraft, with a 60-meter wingspan, would be powered by hydrogen and could deliver nine days of flight stamina. Each HAP could supply coverage over an area of up to 140 kilometres in diameter, and around 60 aircraft could blanket a country the size of the U.K., according to Cambridge Consultants.To read this article in full, please click here
A German startup wants to use IoT sensors and a wireless-mesh network to detect forest fires within 10 minutes to an hour of when they start as opposed to the hours or even days it can take using current methods based on thermal imaging, satellite surveillance and human smoke spotters.Dryad Networks is developing sensors to detect gases associated with forest fires and engineering how to network them using LoRaWAN and other wireless technologies so the data they gather can be analyzed in the company’s cloud.The sensors are best placed about 10 feet off the ground in trees, secured by screws, making it more difficult for people or wildlife to disturb them and ensuring they won’t be obscured by grass or fallen leaves, according to founder and CEO Carsten Brinkschulte, a veteran of Apple and SAP.To read this article in full, please click here
Software-defined WAN (SD-WAN) is getting a big boost from AIOps as vendors look to simplify operations, lower costs, and optimize WAN performance in the modern cloud era.SD-WAN decouples the control aspect of a network from the hardware to create a virtualized network overlay, while AIOps applies machine learning and data analytics to IT operations to automate processes. The convergence of the two – a.k.a. AI-driven WAN – promises to usher in a new era of WAN networking that enables IT to go beyond optimizing network and application experiences to delivering the best experiences to individual users.

The ps command is key to understanding what's running on your Linux system and the resources that each process is using. It's useful to know how to display the information that ps provides in whatever way helps you focus on the problem you're trying to resolve. One aspect of this is being able to sort the output of the ps aux command by any column to highlight particular information, such as how much memory processes are using or how long they've been running.The trick involves using the ps command's --sort option and knowing how to specify the column that you want to use for the sort. By default, ps sorts by process IDs (PIDs), showing the smallest first. PID 1 will appear at the top of the list, right under the column headings. The rest will follow in numeric order.To read this article in full, please click here
With the COVID-19 pandemic showing no signs of abating, migration to the cloud is expected to accelerate as enterprises choose to let someone else worry about their server gear.In its global IT outlook for 2021 and beyond, IDC predicts the continued migration of enterprise IT equipment out of on-premises data centers and into data centers operated by cloud service providers (such as AWS and Microsoft) and colocation specialists (such as Equinix and Digital Realty).The research firm expects that by the end of 2021, 80% of enterprises will put a mechanism in place to shift to cloud-centric infrastructure and applications twice as fast as before the pandemic. CIOs must accelerate the transition to a cloud-centric IT model to maintain competitive parity and to make the organization more digitally resilient, the firm said.To read this article in full, please click here

Tags provide an easy way to associate strings that look like hash tags (e.g., #HOME) with commands that you run on the command line. Once a tag is established, you can rerun the associated command without having to retype it. Instead, you simply type the tag. The idea is to use tags that are easy to remember for commands that are complex or bothersome to retype.Unlike setting up an alias, tags are associated with your command history. For this reason, they only remain available if you keep using them. Once you stop using a tag, it will slowly disappear from your command history file. Of course, for most of us, that means we can type 500 or 1,000 commands before this happens. So, tags are a good way to rerun commands that are going to be useful for some period of time, but not for those that you want to have available permanently.To read this article in full, please click here
When it comes to effectively managing a multicloud environment, there are a ton of network and application metrics that enterprise customers should be watching.Among enterprises, the trend is toward multicloud environments, which can include workloads running on-premises and in public clouds run by multiple cloud providers such as AWS, Microsoft Azure, IBM/Red Hat, Google Cloud Platform and others. Gartner predicts by 2021, more than 75% of midsize and large organizations will have adopted some form of a multicloud and/or hybrid IT strategy. Likewise, IDC predicts that by 2022, more than 90% of enterprises worldwide will be relying on a mix of on-premises/dedicated private clouds, multiple public clouds, and legacy platforms to meet their infrastructure needs.To read this article in full, please click here
A data center is a physical facility that enterprises use to house their business-critical applications and information. As they evolve, it’s important to think long-term about how to maintain their reliability and security.What is a data center?
Data centers are often referred to as a singular thing, but in actuality they are composed of a number of technical elements. These can be broken down into three categories:
Compute: The memory and processing power to run the applications, generally provided by high-end servers
Storage: Important enterprise data is generally housed in a data center, on media ranging from tape to solid-state drives, with multiple backups
Networking: Interconnections between data center components and to the outside world, including routers, switches, application-delivery controllers, and more
These are the components that IT needs to store and manage the most critical systems that are vital to the continuous operations of a company. Because of this, the reliability, efficiency, security and constant evolution of data centers are typically a top priority. Both software and hardware security measures are a must.To read this article in full, please click here
