The fortune command is generally considered one of the just-for-fun commands that you’ll find on linux systems, but it can prove useful in some interesting ways.How it works
Probably most Linux users run the fortune command only when they’re bored, though I’ve known a few who added the fortune command to the end of their .bashrc files so that every login would provide a little quote or a saying that they’d ponder for as much as 30 seconds before proceeding to more serious work.The fortune command is, however, more versatile than many Linux users realize. In fact, most of the responses to typing “fortune” are not really fortunes at all. Rather than predicting your future or even just the outcome of your day, they provide quotes or lighthearted comments.To read this article in full, please click here
Looking to significantly reinforce its security software portfolio, Cisco has struck a $28 billion cash deal to acquire enterprise and cloud protection company Splunk.Founded in 2003, Splunk’s software platform is known for its wide-reaching ability to search, monitor and analyze data from a variety of systems. Network security teams can use this information to gain better visibility into and gather insights about network traffic, firewalls, intrusion detection systems (IDSes), intrusion prevention systems (IPSes), and security information and event management (SIEM) systems, from on premise and or its cloud-based package, according to Splunk.To read this article in full, please click here

Cisco and F5 have extended their partnership with new technology that lets enterprises balance large amounts of traffic between multiple sites to ensure availability and improve application performance.Specifically, the companies are meshing Cisco’s ACI Multi-Site/Multi-Pod package with F5’s Big IP DNS software to help customers more effectively utilize resources distributed across multiple locations, according to Yousuf Khan, vice president of technical marketing with Cisco’s enterprise and datacenter networking group.ACI is built on Cisco’s intent-based networking technology, which gives customers the ability to implement network and policy changes on the fly and ensure data delivery. ACI Multi-Site typically lets two geographically dispersed data centers link via L2/L3 networks and offers consistent policy enforcement across both sites. The Multi-Pod technology lets multiple groups of equipment within the individual data centers network with each other.To read this article in full, please click here
By: Trent Fierro, Blog Contributor.While digital transformation is a heavily discussed topic, the idea that IT organizations must think differently and adapt to change is rarely mentioned. There’s an expectation that the person with 10 to 15 years of experience using CLI commands will embrace the cloud, templates, and AIOps (AI for IT operations) without hesitation. That they will jump at the chance of using something new and exciting. Wrong!IT transformation involves technology advancements, people, and a new way of looking at processes and outcomes. What this means is that a network refresh usually turns into a discussion on how modern technology helps the team deliver a better user experience. Everyone from the CIO on down is looking for efficiency, and oddly, a way to preserve some form of normalcy.To read this article in full, please click here

Whenever you need to work with lists that are stored as text files on Linux – especially long ones – you can take advantage of some easy commands to make manipulating them a lot easier. Any text file can be easily sorted, but you can also randomly arrange the lines, number them or join files when two share an initial common field. In fact, if you only want to see every other line or every fifth line in a file, you can do that too. This post runs through the commands to do all of these things.Sorting files
The sort command makes sorting text files very easy. To view the contents of a text file in sorted order, all you need to do is type a command like this:To read this article in full, please click here
The UK government has announced it will build a £900 million (US$1.1 billion) supercomputer, to drive the country’s AI research and innovation capabilities.The supercomputer, dubbed Isambard-3 after the 19th century British civil and mechanical engineer Isambard Kingdom Brunel, is set to be installed at the National Composites Centre in Bristol later this year. The University of Bristol is home to the UKRI Centre for Doctoral Training in Interactive Artificial intelligence and is part of the GW4 group of universities — an alliance of research-intensive universities that also includes Bath, Cardiff and Exeter.Bristol University will also host the new AI Research Resource (AIRR or Isambard-AI), a national facility to help support AI research and promote the safe use of the technology. Both the supercomputer and AIRR are financed by the by the AI investment announced the government announced in March.To read this article in full, please click here
The comm command on Linux systems can compare file or directory contents and display the differences in a clear and useful way. Think of “comm” not so much as a reference to “compare” as to “common,” since the command writes to standard output both the lines that are common and the lines that are unique in each of the files or directories.One key requirement when using comm is that the content to be compared must be in sorted order. However, there are ways that you can get away with comparing content that isn’t sorted. Some examples of how to do this will be presented in this post.Comparing files
Normally, when using the comm command, you would compare two sorted text files to see their shared and unique lines. Here’s an example in which a list of friends and a list of neighbors are compared.To read this article in full, please click here
The use of data processing units (DPU) is beginning to grow in large enterprises as AI, security and networking applications demand greater system performance.Much DPU development to date has been aimed at hyperscalers. Looking ahead, DPU use in the data center and elsewhere in the enterprise network is expected to grow. One way that could happen is the melding of DPU technology with networking switches – a technology combination AMD Pensando calls a “smartswitch.”An early entrant in that category is HPE Aruba’s CX 10000, which combines DPU technology from AMD Pensando with high-end switching capabilities. Available since early 2022, the CX 10000 is a top-of-rack, L2/3 data-center box with 3.6Tbps of switching capacity. The box eliminates the need for separate appliances to handle low latency traffic, security and load balancing, for example.To read this article in full, please click here

The arrival of 5G cellular technology was supposed to be the match that set the IoT world on fire, but it hasn’t exactly worked out that way. It’s not that the flames have been doused, but rather that IoT growth has smoldered instead of blazed.5G itself has become widely deployed for a variety of use cases, but adoption has been slow for IoT-centric enterprise applications like health-related wearables, industrial IoT networks, surveillance and security, asset tracking and fleet management.To read this article in full, please click here
The appeal of promising network technologies can be jaded by pressure to adopt untested ideas. When I look over the comments I’ve gotten from enterprise technologists this year, one thing that stands out is that almost three-quarters of them said that entrenched views held by company executives is a “significant problem” for them in sustaining their network and IT operations.“Every story that comes out gets me a meeting in the board room to debunk a silly idea,” one CIO said. I’ve seen that problem in my own career and so I sympathize, but is there anything that tech experts can do about it? How do you debunk the “big hype” of the moment?For starters, don’t be too dismissive. Technologists agree that a dismissive response to hype cited by senior management is always a bad idea. In fact, the opening comment that most technologists suggested is “I agree there’s real potential there, but I think there are some near-term issues that need to be resolved before we could commit to it.” The second-most-cited opening is “I’ve already launched a study of that, and I’ll report back to you when it’s complete.” There’s usually a grain (yeah, often Continue reading

Network assurance tools, which use advanced analytics to optimize and automate network management, are becoming an essential component in every network team’s toolkit.Network assurance was once viewed as a routine IT responsibility. "This attitude essentially reduced assurance to a checkbox," says SQL server consultant Mark Varnas. As enterprises became increasingly data-driven, this perfunctory approach no longer worked. IT leaders needed a better handle on their network in order to advance their data capabilities.And these tools are more than just a simple technology investment. "They're a strategic decision that supports business growth and customer satisfaction," says Matt Aird, CTO at Custom Neon, which makes and sells LED neon lights and signs. "Regular monitoring, clear insights, and preventative measures are vital in competitive markets."To read this article in full, please click here
