Using the Linux fold command to make text more readable

The Linux fold takes lines of text and breaks them into chunks based on the arguments that you provide. With no arguments, fold will break lines at 80 characters.The first example below uses a single-line text file that includes indications of character positions. First, we count the number of characters and lines in the file using the wc -l and wc -l command:$ wc -c wide_text 251 wide_text $ wc -l wide_text 1 wide_text So, this file has 251 characters (including a carriage return) and a single line of text. Next, we display the file using the cat command:To read this article in full, please click here

Intel partners with RISC-V, invests $1B in foundry ecosystem

Intel has joined RISC-V International association, an open hardware standards organization dedicated to designing and building ultralow-power processors. The news comes on the heels of another Intel announcement, that it is investing $1 billion in foundry services.Bob Brennan, vice president of customer solutions engineering for Intel Foundry Services (IFS), will be joining both the RISC-V Board of Directors and Technical Steering Committee. Intel is also partnering with several RISC-V leaders, including Andes Technology, Esperanto Technologies, SiFive and Ventana Micro Systems.[Get regularly scheduled insights by signing up for Network World newsletters.] The RISC-V ecosystem uses an open collaboration model, similar to how Linux and other open-source software products are developed. This is unique in chip design. Developers have freedom to design their processors for specific domains and industries. RISC-V started as a project at UC Berkeley and has gained many supporters, but Intel is by far the biggest supporter to back the project.To read this article in full, please click here

OMG: VTP Is Insecure

One of my readers sent me an interesting pointer:

I just watched a YouTube video by a security researcher showing how a five line python script can be used to unilaterally configure a Cisco switch port connected to a host computer into a trunk port. It does this by forging a single virtual trunk protocol (VTP) packet. The host can then eavesdrop on broadcast traffic on all VLANs on the network, as well as prosecute man-in-the-middle of attacks.

I’d say that’s a “startling revelation” along the lines of “OMG, VXLAN is insecure” – a wonderful way for a security researcher to gain instant visibility. From a more pragmatic perspective, if you enable an insecure protocol on a user-facing port, you get the results you deserve¹.

While I could end this blog post with the above flippant remark, it’s more fun considering two fundamental questions.

Major security vulnerability found in top servers

Security firm Binarly has discovered more than 20 vulnerabilities hiding in BIOS/UEFI software from a wide range of system vendors, including Intel, Microsoft, Lenovo, Dell, Fujitsu, HP, HPE, Siemens, and Bull Atos.Binarly found the issues were associated with the use of InsydeH20, a framework code used to build motherboard unified extensible firmware interfaces (UEFI), the interface between a computer’s operating system and firmware.[Get regularly scheduled insights by signing up for Network World newsletters.] All of the aforementioned vendors used Insyde’s firmware SDK for motherboard development. It is expected that similar types of vulnerabilities exist in other in-house and third-party BIOS-vendor products as well.To read this article in full, please click here

Pluribus named a Futuriom 40 Cloud Infrastructure and Communications Company

Scott Raynovich and the team at Futuriom have compiled their list of private companies that are making waves in cloud infrastructure. Futuriom knows this landscape and the customer trends thoroughly and recognizes companies that are innovating to stay ahead of the market, and delivering what customers need to achieve an agile cloud operating model across all of their distributed cloud locations.

Pluribus is humbled and grateful to be named to the 2022 Futuriom 40, joining a group of companies that are all doing remarkable things in the cloud. As Scott points out in the report and in this Forbes article, the market for cloud technology innovation will remain strong, as “…in many cases, traditional enterprise networking architectures aren’t useful for connecting to the cloud applications and platforms.” Pluribus is dedicated to simplifying cloud networking as organizations grapple with the new realities of the distributed cloud.

Of the top trends in the report, one of them is focused on networking across distributed clouds. Futuriom describes it as follows:

Distributed Cloud Infrastructure: Networking and connectivity platforms need to be engineered to connect cloud resources ranging from the edge to the public cloud. This has computer, networking, and storage elements, Continue reading

Cost of banning Chinese 5G gear soars to $5.6B

Network providers have asked for $5.6 billion to cover the cost of replacing deployed wireless equipment made by Huawei and ZTE, whose gear has been banned from US carrier networks.Congress had set aside $1.9 billion for the program, but a preliminary total of applications for reimbursement revealed a shortfall of $3.7 billion. FCC Chairperson Jessica Rosenworcel seeks Congress to make up whatever the actual amount turns out to be.Wireless equipment manufactured by Huawei and ZTE have been placed on a restricted list by the Commerce Department over concern that they could be a security threat to the US.To read this article in full, please click here
