Podcast co-hosts Derick and Brandon explore the early days of Silicon Valley with Bob Metcalfe, inventor of Ethernet technology.
Hello my friend,
Recently I’ve been engage in some troubleshooting with Cumulus and was looking for the way, how can I send the cl-support file from my switches directly to the vendor support bypassing downloading them to my laptop.

Whenever anyone thinks about freelancing, they just imagine someone being by the beach relaxing and doing soft work either with their laptops or their mobile devices. And actually, this is the aim of freelancing. It helps one to freely work in their comfortable places. Freelance writers also have the choice to choose exactly when they would work and when they would rest. Nothing is forcefully put on them. They live a life of choice.
Though this makes it seem like freelancers have it simple and basic, it is one of the things lots of people don’t understand in the freelancing world.
One of the main issues is that freelancing isn’t a consistent job. This means you could get a lot of jobs in a week and the next month you could get nothing. Getting to a point where you’ll be constantly getting gigs is quite difficult too. There’s a lot of competition in this career choice that is quite rewarding. But it is a sensitive issue if you think about it. It can get quite frustrating too.
For one to succeed in the world of freelancing, you need to Continue reading
When VMware NSX-T 3.0 came out, I planned to do an update session of the VMware NSX Technical Deep Dive webinar along the lines of what I did for AWS Networking a few weeks ago. However, it turned out that most of the new features didn’t take more than a bullet or two on an existing slide, or at most a new slide.
Covering them in a live session and then slicing-and-dicing the resulting recording simply didn’t make sense, so I updated the videos in summer 2020 (the last batch was published in early August).

Welcome to another instalment in my Jinja2 Tutorial series. So far we've learned a lot about rendering, control structures and various functions. Here we'll start discussing language features that help us deal with organizing templates. First constructs we'll look at are include
and import
statements.
Include
and Import
statements are some of the tools that Jinja gives us to help with organizing collections of templates, especially once these grow in size.
By using these constructs we can split templates into smaller logical units, leading to files with well-defined scopes. This in turn will make it easier to Continue reading
I have written about wire-guard previously about how easy it is to set-up a personal vpn
What is the issue: I have never explained the use-case clearly in that post, let me try to re-attempt the write-up again
you see, on a personal basis I need to access few websites which are hosted in India, issue with these websites is that they dont allow any traffic external to the country
There are many browser based proxies out there which can do this task just fine and also paid services, my problem is that when you are exchanging user/password information and financial transactions over these proxies you don’t know how exactly all this data getting exchanged and transmitted
Few Tips from my experience before i get into the post :
-> you need to change ubuntu instances ipv4 forwarding so that it will forward packets through the instance also nats it
root@ip-172-31-34-66:~# cat /etc/sysctl.conf | egrep -i ip_forward net.ipv4.ip_forward=1 root@ip-172-31-34-66:~#
-> Make sure you dont start routing everything first, take public DNS’s and test the system with allowed_ips in the configuration file else you will loose internet access and if not done correctly you will Continue reading
We’re excited to announce the expansion of the Network Analytics dashboard to Spectrum customers on the Enterprise plan. Additionally, this announcement introduces two major dashboard improvements for easier reporting and investigation.
Cloudflare's packet and bit oriented dashboard, Network Analytics, provides visibility into Internet traffic patterns and DDoS attacks in Layers 3 and 4 of the OSI model. This allows our users to better understand the traffic patterns and DDoS attacks as observed at the Cloudflare edge.
When the dashboard was first released in January, these capabilities were only available to Bring Your Own IP customers on the Spectrum and Magic Transit services, but now Spectrum customers using Cloudflare’s Anycast IPs are also supported.
Spectrum is Cloudflare’s L4 reverse-proxy service that offers unmetered DDoS protection and traffic acceleration for TCP and UDP applications. It provides enhanced traffic performance through faster TLS, optimized network routing, and high speed interconnection. It also provides encryption to legacy protocols and applications that don’t come with embedded encryption. Customers who typically use Spectrum operate services in which network performance and resilience to DDoS attacks are of utmost importance to their business, such as email, remote access, and gaming.
Spectrum customers Continue reading

Wanna make your security team’s blood run cold? Remind them that all that time and effort they put in to securing the enterprise from attackers and data exfiltration is currently sitting unused while we all work from home. You might have even heard them screaming at the sky just now.
Enterprise security isn’t easy, nor should it be. We constantly have to be on the offensive to find new attack vectors and hunt down threats and exploits. We have spent years and careers building defense-in-depth to an artform not unlike making buttery croissants. It’s all great when that apparatus is protecting our enterprise data center and cloud presence like a Scottish castle repelling invaders. Right now we’re in the wilderness with nothing but a tired sentry to protect us from the marauders.
During Security Field Day 4, I led a discussion panel with the delegates about the challenges of working from home securely. Here’s a link to our discussion that I wanted to spend some time elaborating on:
BYOD was a huge watershed moment for the enterprise because we realized for the first time that we had to learn to secure other people’s Continue reading
In this discussion, Greg accosts...no, converses with...Simon Sharwood on a variety of issues highly relevant to networking's future. It turns out, Simon is not short on opinions. And thusly, Simon and Greg opine about sundry topics.
The post Heavy Networking 549: The Future Of Networking With Simon Sharwood appeared first on Packet Pushers.
Net-á-porter: The South African Chapter of the Internet Society has been promoting an “Internet-in-a-box” initiative using an SD card to configure an inexpensive Raspberry Pi device. Interested people can configure an SD card or even order a pre-loaded SD card.
Taxing the ‘Net: The Mexico Chapter has gone on record as opposing a digital services tax proposed by the Mexican government. “If this initiative is approved, which would have a negative impact on free access to content and information by citizens, [and] we could find ourselves with a potential instrument of discrimination and censorship,” the Chapter said. The tax on foreign digital services would be 16 percent.
Moving governance forward: Pacific Islands Chapter member Swaran Ravindra noted that cybersecurity and digital inclusion were big topics at the recent Asia Pacific Regional Internet Governance Forum 2020. “Disruptive technologies … have enormous benefits for the Pacific region at large, but we cannot ignore the need for our people to be completely cognizant of the cybersecurity issues which we are being exposed to,” she wrote. “Fiji struggles with cyberbullying, suicide, mental health issues, fraud, and crime [that] technology may have been a part of, either intentionally or unintentionally. In order to leverage technology Continue reading
Cybersecurity consumes an ever-increasing amount of our time and budgets, yet gaps remain and are inevitably exploited by bad actors. One of the biggest gaps is unpatched vulnerabilities: a recent survey found that 60% of cyberattacks in 2019 were associated with vulnerabilities for which patches were availablei.
Most companies have a patch schedule that is barely able to keep up with applying the most important patches to the most critical vulnerabilities. Yet new ones crop up all the time: approximately 15,000 new vulnerability are discovered every year, which translates to one every 30 minutes ii. They impact all types of workloads, from multiple vendors, as well as open source projects.
It’s a constant race to try to find and fix the most dangerous vulnerabilities before the bad actors can exploit them. But ignoring them is not an option.
Why not just patch everything or fix flaws in the code? Because it’s operationally challenging – and almost impossible.
First, patching is an expensive and largely manual process. Second, applications may rely Continue reading
The Internet is a network of networks. In order to find the path between two points and exchange data, the network devices rely on the information from their peers. This information consists of IP addresses and Autonomous Systems (AS) which announce the addresses using Border Gateway Protocol (BGP).
One problem arises from this design: what protects against a malevolent peer who decides to announce incorrect information? The damage caused by route hijacks can be major.
Routing Public Key Infrastructure (RPKI) is a framework created in 2008. Its goal is to provide a source of truth for Internet Resources (IP addresses) and ASes in signed cryptographically signed records called Route Origin Objects (ROA).
Recently, we’ve seen the significant threshold of two hundred thousands of ROAs being passed. This represents a big step in making the Internet more secure against accidental and deliberate BGP tampering.
We have talked about RPKI in the past but we thought it would be a good time for an update.
In a more technical context, the RPKI framework consists of two parts:
