Dealing with SSH MAC Limitations in Modern Systems

Modern SSH configurations can sometimes lead to MAC (Message Authentication Code) limitations when connecting between systems with different client setups. I've recently run into this issue when operating from a Mac and connecting to newer operating systems, like NixOS. These limitations can be frustrating, but they are fixable with minimal effort. This post will show you how to change your SSH client to use an appropriate MAC, even if it's not explicitly allowed in your configuration.

Building NixOS from Another OS to Use as NixOS on OpenStack

A wordy title, but it was fun to write and hammers on "OS;" OpenStack / Operating System. With the release of OpenStack Flex, we have opened up some much needed ease of operation and functionality into our multi-tenant OpenStack platform. One of the many new features in our public cloud is the ability to simply create and manage custom images. In this blog post, we will guide you through creating a NixOS 24.05 QCOW2 image which is cloud ready. We'll use resources found in the nixos-openstack GitHub repository and we'll build all of this from Ubuntu within OpenStack Flex.

Creating a WordPress site using Openstack-Flex

Here I wanted to show our customers and hopefully future customers on how easy it is to host your own Wordpress site using Openstack Flex.

Below is a video that you can follow along with that will take you through a step by step setup.

What is Rackspace Public Cloud (Flex)?

In 2006, before 'The Cloud' became a ubiquitous term, Rackspace launched one of the first utility-based computing services known as Mosso (later Rackspace Cloud). Move ahead to 2010, and you'll find Rackspace partnering with NASA to deliver the first release of OpenStack - a fully open-source and open standard cloud computing platform. In 2012, Rackspace launched the Rackspace Public Cloud based on OpenStack, and shortly thereafter began delivering private (hosted) clouds based on OpenStack. To say OpenStack runs through our veins is an understatement.
