Host list with Hammer CLI

On occasion I need to pull a host list from Satellite 6; and while using the web ui is often simple enough, the hammer cli that comes with foreman is often faster. Here is a quick way to get a full host list: hammer host list That command will print list of all hosts registered with your Satellite server. Filter by OS major version Often when I’m generating this list it’s because someone has asked me something like: “How many RHEL 5, servers do we have?

Upgrade to Fedora 32 - and figuring out containers with Podman!

Over the weekend I decided it was time to test the in-place upgrade on my Fedora 31 webserver to migrate over to Fedora 32. The process for in-place upgrades on Fedora is a fairly straightforward process and has been flawless ( at least in my experience) over the last few years. If you are thinking about kicking the tires on the new Fedora check out the quick tutorial over at Fedora Magazine to learn how easy it is to perform the upgrade.

When is Patch Tuesday?

Microsoft releases updates on a predictable cadence. The second Tuesday of every month is called “Patch Tuesday”. There aren’t any Linux distributions (that I’m aware of) that have a similar release cadence. Package updates are released pretty much as soon as they are ready. Theoretically, you could check for updates every day and always have new updates to install each day. However, if you have decided for one reason or another to just standardize your Linux patching around Microsoft’s patch release dates, then you will need a good way to figure out when the next Patch Tuesday will occur.

Does Linux Need Antivirus?

Back in May of 2017, in the wake of the WannaCry ransomware episode, I published an article outlining the major security advantages that Linux has over other operating systems. I stand by each argument I presented back then, but recently I started to ask myself if anything has changed over the last few years that would call for revisiting this topic. A lot of the information that gets passed around the Linux community is really good, however, sometimes the information surrounding this topic specifically is not always of the highest quality and it can be difficult to decipher fact from fiction.

DNF Update Information - Fedora/CentOS 8

The Fedora operating system comes with an updated version of the famous yum package management utility, called “DNF”. DNF stands for “Dandified YUM”, and it retains the general syntax that users of the yum package manager are used to. If you are reading this post should be familiar with at least the basics of installing and updating packages with YUM or DNF. Take a look at the Fedora Docs if you need a quick refresher on how to install packages with DNF.

Git with the program

TLDR; git is awesome. It will save you time, and headaches if you are working on automation. Recently I’ve put some serious effort into learning and using git for version control. I know what you’re thinking…. probably something like “Just now learning git? Have you been living under a rock?”… I realize that I’m at least 10 years late to this party I just didn’t know what I was missing.
