Random identity generation in Linux

If you need to generate a list of names and addresses to test an application or a script that you're working on, Linux can make that surprisingly easy. There's a command called "rig" that will create name, address and phone number listings. As far as I can tell, out of the box, it only works with U.S. addresses and area codes. However, if this is indeed the case, you might be able to work around this problem.To use the rig command, you can just type "rig" on the command line, and a single name and address will be generated. You will see something like this:$ rig Mavis English 1015 Tulip St Anderson, IN  46018 (317) xxx-xxxx To generate a list with many addresses, use the -c option and specify the number of addresses that you want to see.To read this article in full, please click here

Demonstrate Small Automation Wins

Long long time ago in a country far far away when traveling was still a thing I led an interesting data center fabric design workshop. We covered tons of interesting topics, including automating network services deployments (starting with VLAN self-service for server admins).

As was often the case in my workshops, we had representatives from multiple IT teams sitting in the room, and when I started explaining how I’d automate VLAN deployments, the server administrator participating in the workshop quickly chimed in: “that’s exactly how I implemented self-service for some of our customers, it makes perfect sense to use the same approach for server port and VLAN provisioning”, and everyone else in the room agreed… apart from the networking engineer, who used a counter-argument along the lines of “we only provision a new VLAN or server port every few days, we can do it by hand” and no amount of persuasion would move him.

Don’t Make Parents Raise Kids in a World without Encryption

Natalie Campbell, Director of Public Advocacy at the Internet Society and a mother of two, warns against banning or weakening of encryption for the safety of children online. 

Governments and law enforcement agencies are trying to ban or weaken a critical tool for keeping our children safe online. As parents, we must speak up for our kids.

Children who are fortunate enough to have Internet access are online more than ever, and many are increasingly doing learning online. But these spaces are attractive targets for criminals, and parents and schools often lack resources to guide kids on how to stay safe as they learn, socialize, and discover the world online.

Luckily, encryption has our back. Whether it’s sending a confidential message to a friend, videoconferencing with grandparents, or submitting an assignment to a teacher, platforms and services that use end-to-end encryption can help keep our children safe by keeping the line of communication private between the sender and receiver.

Despite this, some governments, law enforcement agencies, and even some child protection agencies are trying take away the strongest digital tool we have as parents to keep children safe online. The United Kingdom, Germany, the European Commission, and the Continue reading

Report: IT employment improves in January

More than 18,000 new IT jobs sprang up in January as the overall outlook for tech hiring substantially improved over the past several months, according to figures from the Bureau of Labor Statistics and research firm Janco Associates.Between that new hiring and adjustments made to the job market totals in the latest BLS numbers, the IT sector has now recouped 53,600 of the roughly 100,000 jobs it lost due to the COVID-19 crisis, according to Janco principal M. Victor Janulaitis.[Get regularly scheduled insights by signing up for Network World newsletters.] What’s more, the upward trajectory seems likely to continue, as the changing IT jobs market grows and changes, according to his projections. “IT job-market growth will expand by almost 11% in the post-COVID era,” he said. “Most of the growth in the IT job market will be with software developers, quality assurance, and testers. This will be driven by [work from home] as it is embraced by more enterprises in normal operations and internet-centric applications are developed and deployed.”To read this article in full, please click here

Network slicing: Wireless virtualization to build 5G services and conserve spectrum

Network slicing technology has large parts of the wireless networking community excited, and it’s easy to understand why: It can deliver multiple logical networks over a single physical infrastructure and give each network the unique set of characteristics required to meet specific user needs.The idea of re-using scarce radio-frequency spectrum to create more value for providers that own the infrastructure, in addition to the ability to offer over-the-top services beyond mere connectivity, has the telecom giants interested, particularly those deploying 5G cellular services.To read this article in full, please click here

CFP for DockerCon LIVE 2021 Now Open!

Ahoy! You can now submit your talk proposal for DockerCon LIVE 2021!

Taking place May 27, 2021, DockerCon brings together the entire community of Docker developers, contributors and partners to share, teach, and collaborate to grow the understanding and capabilities of modern application developers. The Docker community is growing fast and is incredibly diverse, and our aim is to have a conference that reflects this growth and diversity. To that end, we’re announcing the CFP a bit earlier this year to substantially increase the number of submissions to review.

Share your know-how

Like last year’s edition, DockerCon LIVE will be 100% virtual. To allow for conversation and ensure a stress-free delivery for the speaker, session talks will be pre-recorded and played at a specific time during the conference. Speakers will be able to chat live with their audience while their recorded session is broadcast and be available to answer questions in real-time. We’re really excited about this format and we look forward to introducing a host of new interactive features that’ll ensure that speakers (new and seasoned) and attendees alike have an exceptional experience.

The theme of this year’s DockerCon is developer team collaboration in the new remote-first world.

Rethinking BGP on the DC Fabric (part 2)

In my last post on this topic, I laid out the purpose of this series—to start a discussion about whether BGP is the ideal underlay control plane for a DC fabric—and gave some definitions. Here, I’d like to dive into the reasons to not use BGP as a DC fabric underlay control plane—and the first of these reasons is BGP converges very slowly and requires a lot of help to converge at all.

Examples abound. I’ve seen the results of two testbeds in the last several years where a DC fabric was configured with each router (switch, if you prefer) in a separate AS, and some number of routes pushed into the network. In both cases—one large-scale, the other a more moderately scaled network on physical hardware—BGP simply failed to converge. Why? A quick look at how BGP converges might help explain these results.

Assume we are watching the 110::/64 route (attached to A, on the left side of the diagram), at P. What happens when A loses it’s connection to 110::/64? Assuming every router in this diagram is in a different AS, and the AS path length is the only factor determining the best path at every router.

Who won Super Bowl LV? A look at Internet traffic during the game

Who won Super Bowl LV? A look at Internet traffic during the game
Who won Super Bowl LV? A look at Internet traffic during the game

The obvious answer is the Tampa Bay Buccaneers but the less obvious answer comes from asking “which Super Bowl advertiser got the biggest Internet bump?”. This blog aims to answer that question.

Before, during, and after the game a crack team of three people who work on Cloudflare Radar looked at real time statistics for traffic to advertisers’ websites, social media in the US, US food delivery services, and websites covering (American) football. Luckily, one of us (Kari) is (a) American and (b) a fan of football. Unluckily, one of us (Kari) is a fan of the Kansas City Chiefs.

Cloudflare Radar uses a variety of sources to provide aggregate information about Internet traffic and attack trends. In this blog post we use DNS name resolution data to estimate traffic to websites. We can’t see who visited the websites mentioned below, or what anyone did on the websites, but DNS can give us an estimate of the interest generated by the commercials. This analysis only looked at the top-level names in each domain (so example.com and www.example.com and not any other subdomains).

The Big Picture

To get the ball rolling here’s a look at traffic to Continue reading

The Week in Internet News: Toronto Looks to Community Broadband

Broadband for the city: Toronto, the largest city in Canada, will consider building a municipal broadband network to bridge the digital divide, Now Toronto reports. A government committee has endorsed the ConnectTO initiative, which aims to fill in underserved areas in the city while avoiding competition with current Internet service providers. Meanwhile, Tucson, Arizona, is building its own municipal broadband network, StateScoop says. The network will focus on serving government offices, students, and elderly residents who lack reliable Internet service.

Protesting subsidies: In another broadband story, some rural ISPs are questioning an $886 million U.S. Federal Communications Commission rural broadband subsidy to SpaceX, the Elon Musk-owned company that has launched a satellite-based Internet service, reports Bloomberg on Al Jazeera. Some rural ISPs have suggested the satellite service is still in beta and plans to serve parts of New York City and airports in Newark and Miami, which don’t fit in with the mission of the FCC’s Rural Digital Opportunity Fund.

Giant regulation: A new Japanese law requires tech giants to disclose terms of contracts with business partners and submit reports regularly to the government, in an effort to enforce fair business relationships with smaller companies, The Japan Times reports. The Continue reading
