7 ways to remember Linux commands

Some Linux commands are very easy to remember. The names may have only a couple letters and they often relate directly to what you want to do – like cd for changing directories or pwd for displaying the present working directory. Others can be very difficult to remember, especially if what you want to do relies on using a series of options.So, let’s look at some commands and tricks that can help you remember commands that do just what you need them to do and that make issuing those commands so much easier.Use aliases The best way to nail down a complicated command is to turn it into an alias. Just take a command that works for you and assign it an easy name. In fact, there is nothing wrong with using the name of the command itself as the alias as long as this doesn’t interfere with other ways you might want to use that command. For example, grep and egrep are often aliased to include using color to highlight your search term.To read this article in full, please click here

IDG Contributor Network: Secure SD-WAN: The security vendors and their SD-WAN offerings

During its inception, we had the early adopters and pure SD-WAN players. Soon it became obvious that something was missing, and that missing component was “security.” However, security vendors have highlighted the importance of security from the very beginning.Today, the market seems to be moving in the direction where the security vendors are focusing on delivering SD-WAN features around pervasive security. The Magic Quadrant for WAN Edge Infrastructure has made a substantial prediction. It states, “By 2024, 50% of new firewall purchases in distributed enterprises will utilize SD-WAN features with the growing adoption of cloud-based services, up from less than 20% today.”To read this article in full, please click here

Claudio Jeker Honored by Internet Security Research Group with Radiant Award

This week another Radiant Award has been awarded by the Internet Security Research Group, the folks behind Let’s Encrypt. The award puts the limelight on the heroes who make the Internet more secure and trustworthy each day.

The newest Radiant Award winner is Claudio Jeker, who receives the prize for his work of a BGP4 implementation on OpenBSD. This makes me horrendously enthusiastic. Why?

OpenBSD is a open-software based operating system that is focused on being secure and feature complete. It comes with a set of tools that make it ideally suited to be deployed, for instance, as a secure route server in an Internet Exchange Point (IXP). A route server is a service that an IXP can host in order to make the participating network service providers lives a little easier. They do not have to get the routing information from each other, but can simply talk to this piece of centralized infrastructure. OpenBSD allows this type of infrastructure to be build from commodity components in a scalable and secure way.

With a route server in place, an IXP can take additional measures to secure the Internet, namely by taking the MANRS actions.

Ultimately this would not be Continue reading

New tools to monitor your server and avoid downtime

When your server goes down, it’s a big problem. Today, Cloudflare is introducing two new tools to help you understand and respond faster to origin downtime — plus, a new service to automatically avoid downtime.

The new features are:

• Standalone Health Checks, which notify you as soon as we detect problems at your origin server, without needing a Cloudflare Load Balancer.
• Passive Origin Monitoring, which lets you know when your origin cannot be reached, with no configuration required.
• Zero-Downtime Failover, which can automatically avert failures by retrying requests to origin.

Standalone Health Checks

Our first new tool is Standalone Health Checks, which will notify you as soon as we detect problems at your origin server -- without needing a Cloudflare Load Balancer.

A Health Check is a service that runs on our edge network to monitor whether your origin server is online. Health Checks are a key part of our load balancing service because they allow us to quickly and actively route traffic to origin servers that are live and ready to serve requests. Standalone Health Checks allow you to monitor the health of your origin even if you only have one origin or do not yet Continue reading

Practice Your Public Cloud Networking with Hands-On Exercises

Design assignments and hands-on exercises were always a big part of ipSpace.net online courses, and our new Networking in Public Cloud Deployments course is no different.

You’ll start with a simple scenario: deploy a virtual machine running a web server. Don’t worry about your Linux skills, you’ll get the necessary (CCIE-level) instructions and the source code for the web server. Building on that, you’ll create another subnet and deploy another virtual machine acting as a back-end application server.

And then we’ll get to the fun part:

Open Source Flow Monitoring and Visualization

At the heart of any reasonably sized network, should be a solid strategy around flow collection, querying and visualization. Proper use of flow logs are crucial to SecOps/NetOps from triaging attacks to capacity planning and traffic trending. I remember some 20 years ago, the first time I saw flow logs being visualized in rrdtools it was pretty close to magic. ... The post Open Source Flow Monitoring and Visualization appeared first on NetworkStatic | Brent Salisbury's Blog.

HashiCorp’s Consul Brings Namespace Management to the Service Mesh

Consul services networking platform with the capability to manage service namespaces at an organization-wide level. Released Tuesday, Consul 1.7 also comes with additional plugins to support a number of application monitoring and management tools, including AppDynamics, Datadog and the NGINX proxy. HashiCorp presents Consul as a network automation tool for enterprises to connect and secure application services across multiple clouds and on-prem environments, putting all the services on a single communication plane with a shared registry. The thinking behind Consul is that “you need a namespace service registry for the new, dynamic environment,” noted on the HashiCorp blog. HashiCorp is a sponsor of The New Stack. Feature image
