IDG Contributor Network: School district repurposes buses as Wi-Fi hotspots

A poverty-stricken school district in Southern California has come up with a novel way to alleviate the lack of internet access for kids in its catchment area. It’s repurposing school buses as internet hotspots.The school buses are parked overnight in impoverished areas where hard-wired broadband Internet access isn’t usually available and students aren’t able to access the internet. Most of the school district’s students reside in stone-broke rural areas and/or reservations.All of the children in the vast, 1,220-square-mile school district qualify for reduced-priced or free meals, says the Office of Educational Technology (OET). And almost half of the students are English-language learners.To read this article in full or to leave a comment, please click here

HELLO, WORLD

Welcome to Cloud Packet! I’m Shakib Shaygan, a full-time blogger and network engineer who has been designing and building networks for over 6 years now. I recently completed the CCIE lab to earn CCIE #46559 (Routing and Switching & Data Center), besides that I have some knowledge of open source and other networking product such as Juniper & Brocade.

As for a bit of background, I’ve worked as a normal IT Support, help desk, and currently as a network researcher, focusing on SDN for Telco. Currently I’m looking forward to doing some research, learning, and writing on a variety of networking-oriented topics. Look for a series of posts related to the CCIE Data Center experience as well as any other interesting topic which I encounter.

One of the reasons that I start this blog was to have a base that I can share my notes, as usually I write down everything that I learn because we are human and we will forget most of them for sure.

Massive growth shows why Amazon is the public cloud leader

Amazon showed off its dominance in the public cloud market on Thursday as the capstone to a better than expected quarterly earnings report.Revenue from Amazon Web Services during the first quarter of 2016 was up 64 percent year-over-year, showing the big money that's still out there as companies invest more and more in the public cloud. Amazon's cloud platform generated revenue of $2.56 billion, putting it on pace to make $10 billion this year, in line with a letter from CEO Jeff Bezos sent to shareholders earlier this month. That's big money to go with Amazon's massive customer base, which includes names like Netflix, Time Inc., and Intuit. To read this article in full or to leave a comment, please click here

Running docker containers with native L2 networking & DHCP

A container normally comes up on the docker0 bridge with an IP from the static docker pool. This can be configured by editing docker options and restarting docker engine.

There are cases where a container needs to come up on a pre-existing bridge or a user defined bridge. This can be achieved by giving the --net option during docker run or configuring docker daemon options pre to docker engine boot. Creating an image with dhclient installed in it & programmed to start automatically is one way of doing l2-dhcp from the physical network infrastructure. There are other ways of doing this - macvlan, ipvlan or manually plugging in a veth pair between the docker container namespace and the host network stack. I will describe the former method here. macvlan and veth pair addition methods are described here [Cr1].

Step 1: Build a docker image with the required set of tools. An example is given below. This installs dhclient, netutils and iputils along with running sshd. User root’s password is set to centos using the start.sh script. Dockerfile & script source attributed to maxamillion (github link)

With some advanced preparation, you can survive a ransomware attack  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  You know it's bad when a cyber crime wave makes victims out of U.S. police departments. Law enforcement agencies in at least seven states have been blackmailed by cyber attackers using ransomware. Data on departmental computers has been encrypted by malware and held hostage, with the demand that a ransom be paid in bitcoins. Unaccustomed to giving in to criminals, many of the agencies refused to pay and subsequently lost access to their information forever.Cyber criminals also have been targeting U.S. hospitals. In one high profile case, a California hospital lost access to its critical patient records for a week until a ransom worth about $17,000 was paid. Experts estimate this particular facility was losing as much as $100,000 a day in just one department because it wasn't able to perform CT scans without access to its data.To read this article in full or to leave a comment, please click here
