Wow, what a busy month this has been!
So I started my new job on February 1st and thus far, everything has been really great.
My new coworkers are very friendly and helpful.
I’ve spent the better part of february, trying to get to grips with the SP network I will be focusing on from now on. Im still not where I want to be yet, but im getting there. One of the guys I will be working very closely with, started cleaning up the network when he was hired 9 months ago and he’s done a really great job with what he’s had to work with.
There are still some work to be done however, which is the very reason they have hired me and another very good friend of mine. A well run network is a dynamic beast which needs to be tamed. On top of that, the company growth has been around 30% a year, so alot of structure and processes needs to come with that growth, which is where I can really make a difference.
I’ve also had the good fortune of being selected as a 2016 Cisco Champion, which was a very nice surprise. I Continue reading
To learn more about OpenStack cloud management software, a student or research may install OpenStack on a single machine, such as a laptop computer or a virtual machine, and emulate a small datacenter using virtual machines or containers.
Researchers and students may choose from multiple projects that will set up OpenStack on a single machine. Some projects are community-based open-source projects and others are vendor supported projects (while still nominally open-source).
This post is an overview of links and resources to installing OpenStack on one machine.
DevStack is a community-driven open-source project that provides scripts and drivers to install OpenStack on a single machine. It includes direction to install on a laptop computer and to install on a single virtual machine. Devstack may also be configured to use LXC containers as compute nodes, or to use nested KVM virtualization for compute nodes.
Openstack Autopilot is the Ubuntu OpenStack installer. It is free as long as you use less than ten machines in your cloud infrastructure. So, most students and researchers will be able to play around with Autopilot for free.
Autopilot will set up an OpenStack cloud using LXD containers. This means that the system can Continue reading

Just in case you wondered why HP doesn’t have an hyperconverged system, here is what Meg Whitman said this quarter investors call: Looking forward, you can expect this momentum and investment in innovation to continue. Later this month, we will announce a new market-changing hyper-converged offering based on our industry-leading ProLiant virtualization server. Our new […]

Yesterday we wrote about the 400 gigabit per second attacks we see on our network.
One way that attackers DDoS websites is by repeatedly doing DNS lookups that have small queries, but large answers. The attackers spoof their IP address so that the DNS answers are sent to the server they are attacking, this is called a reflection attack.
Domains with DNSSEC, because of the size of some responses, are usually ripe for this type of abuse, and many DNS providers struggle to combat DNSSEC-based DDoS attacks. Just last month, Akamai published a report on attacks using DNS lookups against their DNSSEC-signed .gov domains to DDoS other domains. They say they have seen 400 of these attacks since November.
To prevent any domain on CloudFlare being abused for a DNS amplification attack in this way, we took precautions to make sure most DNS answers we send fit in a 512 byte UDP packet, even when the zone is signed with DNSSEC. To do this, we had to be creative in our DNSSEC implementation. We chose a rarely-used-for-DNSSEC signature algorithm and even deprecated a DNS record type along the way.
