IDG Contributor Network: LoRa-based IoT service helps farm co-ops cultivate more land

Farming is difficult. Farming outside the power grid is close to impossible.For many electric utilities, it’s hard to justify the investment needed to extend the power grid to remote farms. Cellular providers also prefer to build cell towers where there are many customers. On top of that, farmers have little purchasing power individually, making it hard for them to negotiate power and coverage from large utilities and cellular providers.The power of cooperatives Farmers strengthen their bargaining power by forming cooperatives. This enables them to negotiate for more services and better prices. Cooperatives are businesses-owned and controlled by the people who use them—not shareholders. There are nearly 3,000 farmer cooperatives in the U.S. owned by a million farmers and ranchers.To read this article in full or to leave a comment, please click here

The New Strange Behavior for OSPF ‘Redistribute Subnets’

In older IOS Code, there was a specific requirement for redistributing OSPF Subnets. In almost every case, the keyword “subnets” had to be added to the redistribute command.

Older Code Example–

//notice the warning when 'subnets' is omitted
R1(config)#router ospf 1
R1(config-router)#redistribute eigrp 1
% Only classful networks will be redistributed

//and the configuration is stored exactly as it was typed
R1(config-router)#do show run | sec router
router ospf 1
 log-adjacency-changes
 redistribute eigrp 1

//we can change the behavior by adding 'subnets'
R1(config-router)#redistribute eigrp 1 subnets

//after adding, it is stored as one would expect
R1(config-router)#do show run | sec router
router ospf 1
 log-adjacency-changes
 redistribute eigrp 1 subnets

When I tested this in VIRL running 15.6(1S) running inside of IOS XE 3.17, the warning goes away. The question I had is whether it is still relevant or not.

Current Code Example–

//without the 'subnets' keyword
csr1000v-2(config)#router ospf 1
csr1000v-2(config-router)#redistribute eigrp 1
csr1000v-2(config-router)#do show run | sec router
router ospf 1
 redistribute eigrp 1

//with the 'subnets' keyword
csr1000v-2(config-router)#redistribute eigrp 1 subnets
csr1000v-2(config-router)#do show run | sec router
router ospf 1
 redistribute eigrp 1 subnets

I initially spent some time experimenting with this and thought that ‘subnets‘ had Continue reading

Why we use the Linux kernel’s TCP stack

A recent blog post posed the question Why do we use the Linux kernel's TCP stack?. It triggered a very interesting discussion on Hacker News.

I've also thought about this question while working at CloudFlare. My experience mostly comes from working with thousands of production machines here and I can try to answer the question from that perspective.

Let's start with a broader question - what is the point of running an operating system at all? If you planned on running a single application, having to use a kernel consisting of multiple million lines of code may sound like a burden.

But in fact most of us decide to run some kind of OS and we do that for two reasons. Firstly, the OS layer adds hardware independence and easy to use APIs. With these we can focus on writing the code for any machine - not only the specialized hardware we have at the moment. Secondly, the OS adds a time sharing layer. This allows us to run more than one application at a time. Whether it's a second HTTP server or just a bash session, this ability to share resources Continue reading

Overlay Tunneling with Open vSwitch – GRETAP, VXLAN, Geneve, GREoIPsec

Building overlay networks using tunnels was always done to achieve connectivity between isolated networks that needed to share the same policies, VLANs or security domains. In particular, they represent a strong use-case in the data center, where tunnels are created between the hypervisors in different locations allowing virtual machines to be provisioned independently from the physical network.
