Fedora 29 now has kernel 4.

The Home Assistant project provides a great open source way to get started with home automtion that can be entirely self-contained within your home.

Managing iptables gets a lot easier with firewalld.

I’m at the 2018 Red Hat Summit this week in San Francisco and I am enjoying the interactions between developers, executives, vendors, and engineers.

Walt Disney said it best:

If you’re on the latest Fedora release, you’re already running lots of modern packages.

The Overland Expo in Asheville last year was a great event, and one of my favorite sessions covered the basics about radio communications while overlanding.

After a recent OpenStack-Ansible (OSA) deployment on CentOS, I found that keepalived was not starting properly at boot time:

The latest release of the Red Hat Enterprise Linux Security Technical Implementation Guide (STIG) was published last week.

I’ve been working through some patches to OpenStack-Ansible lately to optimize how we configure yum repositories in our deployments.

Thunderbird is a great choice for a mail client on Linux systems if you prefer a GUI, but I had some problems with fonts in the most recent releases.

I have a CyberPower BRG1350AVRLCD at home and I’ve just connected it to a new device.

Tons of improvements made their way into the ansible-hardening role in preparation for the OpenStack Pike release next month.

My new ThinkPad arrived this week and it is working well!

All systems running systemd come with a powerful tool for reviewing the system journal: journalctl.

When I came back from the holiday break, I found that the openstack-ansible-security role wasn’t passing tests any longer.

OpenStack’s compute service, nova, manages all of the virtual machines within a OpenStack cloud.

The OpenStack Zuul system has gone through some big changes recently, and one of those changes is around how you monitor a running CI job.

Most of the recent Fedora upgrades have been quite smooth.

The 2016 Red Hat Summit is underway in San Francisco this week and I delivered a talk with Robyn Bergeron earlier today.

When you’re ready to commit code in an OpenStack project, your patch will eventually land in a Gerrit queue for review.

When I started Thunderbird today, it opened three windows.

On most IPv6-enabled networks, network addresses are distributed via stateless address autoconfiguration (SLAAC).

UPDATE: The fixed version of mutter is now in the Fedora updates repository.

After getting a bit overzealous with cleaning up bookmarks in Chrome, I discovered that I deleted a helpful Gerrit filter for OpenStack reviews.

I’m a big fan of the pyenv project because it makes installing multiple python versions a simple process.

Although I use GNOME 3 as my desktop environment, I prefer KDE’s kwallet service to gnome-keyring for some functions.

I’ve talked about predictable network names (and seemingly unpredictable ones) on the blog before, but some readers asked me how they could alter the network naming to fit a particular situation.

Updating Dell PowerEdge firmware from Linux is quite easy, but it isn’t documented very well.

I’ve been a big fan of Thunderbird for years, but it lacks features in some critical areas.

I spent some time working with macvlan interfaces on KVM hypervisors last weekend.

Switching to systemd-networkd for managing your networking interfaces makes things quite a bit simpler over standard networking scripts or NetworkManager.

The blog posts have slowed down a bit lately because I’ve been heads down on a security project at work.

Earlier today, I wrote a post about my first thoughts on the Supermicro 5028D-T4NT server.

I’ve recently moved over to Rackspace’s OpenStack Private Cloud team and the role is full of some great challenges.

If you’re running Fedora 22 and you’ve recently updated to systemd-219-24.

Although Time Warner Cable is now Spectrum and wide-dhcpv6 is quite old, this post is still what I’m using today (in 2019)!

I’ve decided to start a series of posts called “Chronicles of SELinux” where I hope to educate more users on how to handle SELinux denials with finesse rather than simply disabling it entirely.

I’ve had a great time talking to people about my “Be an inspiration, not an impostor” talk that I delivered in August.

I received some good feedback about my post on systemd-networkd and bonded interfaces on Rackspace’s OnMetal servers, and I decided to write about another use case.

This post originally appeared on the Fedora Magazine blog.

I talked a bit about systemd’s network device name in my earlier post about systemd-networkd and bonding and I received some questions about how systemd rolls through the possible names of network devices to choose the final name.

I’ve written about systemd-networkd in the past and how easy it can be to set up new network devices and tunnels.

It seems like there’s a new way to run containers every week.

Fedora Flock 2015 is still going here in Rochester, New York, and I kicked off our second day with a keynote talk about overcoming impostor syndrome.

I decided to change some of my infrastructure back to KVM again, and the overall experience has been quite good in Fedora 22.

I’ve recently set up a Fedora 22 firewall/router at home (more on that later) and I noticed that remote ssh logins were extremely slow.

My upgrade to Fedora 22 on the ThinkPad X1 Carbon was fairly uneventful and the hiccups were minor.

I stumbled upon a strange bug at work one day and found I couldn’t connect to our wireless access points any longer.

GNOME 3 generally works well for me but it has some quirks.
