Hi All,
I have slightly changed this to networking, but the intention and my current use is to measure the water level of a sump, since that deviates from the network blog writing, i have extended the same to a Router.
Purpose – Have a Router and also a Syslog Server which monitors my internal network (This can easily be extended to a Car / Moisture Sensor or a Temperature/Humidity Sensor), what we want to do is to make sure if any anomaly is seen in Log Messages, it logs to IOT service. We can then take this up as a Part-2 writing to perform a specific action / automated on what action can be taken to mitigate
Discussion about configuring a Linux device is out of scope, so lets think that we all have that setup. What happens next ?
Lets quickly see our python script, which parses for a anomaly, in this lets say when someone runs a ping command, well its not a anomaly but will do for our use-case.
logparse.py is our program, so i have imported it into the readily available sample program provided by AWSIOT Kit, so you dont have to know Continue reading
BGP is the kitchen-sink of networking protocols, right? Whatever control-plane information you need to transport around, you can do it with BGP… including the battleship coordinates carried in BGP communities.
On the more serious front, it's nice to see at least some ISPs still care enough about the stability of the global Internet to use BGP route flap dampening.
Intel Atom failures I know the title sounds a bit weird and you may ask why would you need to recover a RAID5 array when all your disks are healthy, right? To understand what is going on, my DS1515+ has an Intel Atom C2538. (source: Synology CPU / NAS Type). It recently caused a lot of issues in the IT industry. (remember the Cisco clock issue? ? ) The Errata AVR54 of the C2000 Specifications update clearly states the following: “system may experience inability to boot or may cease operation”. My NAS was starting to have regular reboots and it completely crashed before I could back up the last delta of data. In the first instance, Synology denied any abnormal failure rate on this specific [Read More...]

One critical decision that executives need to make when assessing their data center architecture is their approach to software vulnerability management across all network components. Vulnerability management primarily revolves around selecting an efficient and modern software management strategy. There are several ways to execute on a software management strategy, and I believe disaggregation is a critical first step in doing it right.
In this post, I want to take a minute to first share my thoughts on the vulnerability management trends I’ve noticed. I will argue that a) you need to prioritize the network in how you manage vulnerabilities and b) disaggregation is the only way to do it properly. We’ll also take a look at the reasons why I think we never had the right framework to manage software delivery, making vulnerability management a challenge on platforms that are closed in nature.
Three weeks ago, I joined 40,000 security professionals in San Francisco to attend the biggest gathering of security conscious professionals — RSA Conference. While there were several presentations and moments from the event that stood out, one that caught my eye was a presentation that discussed challenges in the industry Continue reading
The cloud touches all parts of Cisco’s business making this an important investment area for the company.
Following the Equifax breach, which exploited an open source framework library, many organizations increased their security postures, but that doesn't mean that open source is safe to use again.
Sherlock, a cloud-based platform-as-a-service, will target IoT use cases and verticals including retail, manufacturing, health care, and oil and gas.
AT&T, Google, and Microsoft highlighted significant progress for the ecosystem, but an enterprise survey showed most remain on the sidelines of actual deployment.
The Internet is a network of networks. Where do each of these networks meet to form the global Internet? At Internet Exchange Points or IXPs. In North America, these IXPs are also known as network access points, or NAPs.
Over the years, connecting to a NAP has become increasingly crucial for service providers to get right because of the sheer volume of traffic the Internet carries these days (Hello, Netflix!), the complexity of service provider peering agreements, and endless troubles with security threats.
Joining us today to discuss how to better plan, design, operate, and secure peering is our sponsor Cisco. Our guests from Cisco are Phil Bedard, Service Provider TME; and Bruce McDougall, Consulting Systems Engineer.
We discuss the evolution of Internet traffic flow and interconnection, how peering designs among service providers have changed, the role of telemetry and data, and peering security issues.

A nonprofit telecommunications provider offering voice and data services to remote areas in southern Mexico has avoided a crippling federal fee after challenging it in court.
A Mexican court recently ordered the Federal Institute of Telecommunications to reconsider the spectrum fee for Indigenous Community Telecommunications (ICT), which serves about 3,500 customers. The fee, about 1 million pesos or US$50,000, is equal to about half of ITC’s annual operating budget, said Peter Bloom, founder and a board member of ITC.
But the ruling, by the Collegiate Circuit Court on Administrative Matters, Specialized in Economic Competition, Broadcasting and Telecommunications, doesn’t end the legal battle between the nonprofit ISP and the federal regulator.
ITC doesn’t feel like the regulator honored the ruling, Bloom said, even though it exempted the ISP from fees in 2017 and beyond as long as it maintains its nonprofit status.
The court instructed the regulator to “take into account fundamental human and constitutional rights when deciding how or if to charge for spectrum use,” he added. “In our case, our mission is social, but we were being taxed as a commercial cellular provider in an amount that would make it impossible for us to continue operating.”

SD-WAN is about migrating your legacy hardware away from silos like MPLS and policy-based routing and instead integrating everything under one dashboard and one central location to make changes and see the impacts that those changes have. But there’s one thing that SD-WAN can’t really do yet. And that’s prepare us the for the end of TDM voice.
Voice is a way of life for some people. Cisco spent years upon years selling CallManager into every office they could. From small two-line shops to global organizations with multiple PRIs and TEHO configured everywhere. It was a Cisco staple for years. Which also had Avaya following along quickly to get into the act too.
Today’s voice world is a little less clear. Millenials hate talking on the phone. Video is an oddity when it comes to communications. Asynchronous chat programs like WhatsApp or Slack rule the day today. People would rather communicate via text than voice. We all have mobile devices and the phone may be one of the least used apps on it.
Where does that leave traditional voice services? Not in a good place for sure. We still need phone lines for service-focused businesses Continue reading
