History Of Networking – Juliusz Chroboczek – Babel Routing Protocol
Babel is a relatively new routing protocol when compared to some of the more well established options, but due to some of its design considerations, it is very well suited for routing on distributed mesh networks. Babel’s creator, Juliusz Chroboczek, joins the Network Collective team in discussing how Babel came about, some of the design decisions when creating it, and what the future looks like for this emerging technology.

IS-IS Overload Bit – Why IS-IS Overload bit is used ? What are the use cases ?
IS-IS Overload Bit – Why IS-IS Overload bit is used ? What are the use cases ? In this post, I will explain the Overload bit which is an important feature of IS-IS routing protocol. When a router which runs an IS-IS routing protocol have resource issue (CPU, Memory), device shouldn’t receive network traffic. […]

When it comes to packet capture, a hardware analyzer will produce different results vs. a software-based tool.
A Brief Look at VMware’s Three Cloud Approaches
I’m at VMworld 2017 this week (obviously, based on my tweets and blog posts), and in the general sessions Monday and yesterday VMware made a big deal about how VMware is approaching cloud computing and cloud services. However, as I’ve been talking to other attendees, it’s become clear to me that many people don’t understand the three-pronged approach VMware is taking.
I should start out by saying that this post hasn’t been officially reviewed by VMware (none of my stuff is) and may not align with the “approved” marketing approach, so keep that in mind. This is just me speaking.
As I see it, the three cloud approaches are as follows:
- Private cloud
- VMware Cloud on AWS
- VMware Cloud Services for native cloud workloads
The first option (private cloud) is, I think, pretty much self-explanatory. VMware is offering VMware Cloud Foundation to help streamline some of the infrastructure management in this space, and then the VMware SDDC stack (vSphere, vSAN, and NSX) are layered on top. Couple that with a cloud management platform/automation platform such as OpenStack (VIO would be a good option) or vRealize Automation, and you have a private cloud. (I’m glossing over a few details, but you Continue reading
Automation Tools in Building Network Automation Solutions Online Course
A network engineer interested in attending the Building Network Automation Solutions online course sent me this question:
Does the course cover only Ansible, or does it also cover other automation tools like Python?
The course focuses on how you’d build a network automation solution. Selecting the best tool for the job is obviously one of the major challenges, and so one of the self-study modules describes various automation tools and where you could use them to build a full-blown solution.
Read more ...ReFS integrity is not on by default
I really don’t like the trend of filesystem authors to only care about filesystem integrity by default. How about having seat belt for your data integrity by default and let people turn it off if they want to compromise correctness for performance?
What I didn’t know is that ReFS integrity is not on by default. Only metadata integrity.
It’s also not visible or changeable in the UI (which is why I assumed they’d done the right thing), which is strange to me, this being Windows. No, you have to drop down into Microsoft’s crappy CLI.
How to check if it’s turned on.
Check files in one directory
PS E:\> Get-Item '*' | Get-FileIntegrity
FileName Enabled Enforced
-------- ------- --------
E:\SomeDirectory False True
E:\SomeOtherDirectory False True
E:\SomeFile.txt False True
[...]
Fuck you, Microsoft.
Check recursively
Of course Get-Item doesn’t do recursion. Why would it? That would
make sense.
PS E:\> Get-Children -Recurse 'E:\SomeDirectory' | Get-FileIntegrity
FileName Enabled Enforced
-------- ------- --------
E:\SomeDirectory\foo.txt False True
[...]
How to enable it
Both commands are needed. The first command sets the new default for the root directory, and the second adds checksums to all existing files and directories.

Since launching the Docker Captains over a year ago, we’ve received a lot of questions: What is a Docker Captain? What do Captains do? How do I become a Captain? So who better to answer that than the Docker Captains themselves? At DockerCon Austin, we asked the Docker Captains to share their favorite thing about wearing the Captain’s hat.
What is a Captain?
Captains are Docker experts that are leaders in their communities, organizations or ecosystems. As Docker advocates, they are committed to sharing their knowledge and do so every chance they get!
What do Captains do?
Captains are advisors, ambassadors, coders, contributors, creators, tool builders, speakers, mentors, maintainers and super users and are required to be active stewards of Docker in order to remain in the program.
In addition to sharing their knowledge with the community, Captains provide insight and feedback to Docker. They have direct access to our technical teams, and are first to hear about and try upcoming features, product releases and big announcements.
What do Captains get?
In return for their efforts, Captains get access to the existing captains community and Docker staff. They get ongoing training, private briefings and Slack chat channels where Captains Continue reading

Why You Should Attend AnsibleFest
It’s that time again! The time when automators from all over converge at the official event for all things Ansible — AnsibleFest San Francisco! Fresh off the heels from a packed house at AnsibleFest London in June, AnsibleFest San Francisco is shaping up to be the biggest AnsibleFest ever. With about a week before showtime, now’s the best time to start planning a trip to the “City by the Bay” for a fantastic event before it sells out.
To give a better idea of what to expect (and how to convince your manager to go), I’ve provided the top five reasons to go to AnsibleFest in San Francisco:
1. Expanded agenda and a session on Key Topics and Trends with Jim Whitehurst Red Hat CEO
We’ve heard your feedback, and listened: now more breakout sessions! We have made an unprecedented increase in sessions, up from 16 to 25, from customers, partners and the community. All session have been posted to the AnsibleFest agenda so you can see the better-than-ever lineup we have created.
2. All Ansible, all the time
Of course, we realize that Red Hat Summit is the company’s flagship event (I’ve been to seven of them), but Summit Continue reading
