I wanted to install vim package on FreeBSD 13.0, and did so without realizing that there were over 86 additional dependency packages installed. This was done with pkg install -y vim command. Anyway, I wanted to clean up by removing vim and those dependencies after all this is a headless server. Removing vim package doesn’t remove the installed dependencies. Fortunately, I was able to copy and paste the names of dependency packages and save it to a file....
I just formatted an external drive with exFAT file system with the intention to share this drive between Windows/Linux/macOS. When the drive is mounted on my Fedora desktop, it shows as: /dev/sde1 on /run/media/kenno/E17F-B2B1 type exfat ()(rw,nosuid,nodev,relati...) I want to give it a name, so it’ll be mounted as: /run/media/kenno/DRIVE_NAME. On Linux system, we can use a tool called exfatlabel to get or set the exFAT file system. I already created a partition and format it (mkfs....
I’ve been running Fedora 34 pre-release version even before it became beta. Everything has been working so far until recently when a package dracut was updated from 0.58 to 0.58-1. What is dracut? Good question. It’s an initramfs infrastructure used on Fedora system. Find out more from Dracut. The issue that introduced in version 0.58-1 on F34 is that it prevents any machines that use LUKS encryption for root partition to boot....
On my Fedora 33 system, the systemd journal is persistently logged. Over time, the size of the log accumulate quite a lot. # du -shx journal/ 4.2G journal/ I already cleaned up the log twice in the past, but I already forgot how to do it. To fix my short-term memory, I’m going to document how I do this by following this blog post Clear systemd journal. The command for cleaning up old logs is journalctl with the option --vaccume-time=OLDER_THAN_TIME....
I have a need to setup a virtual network on a VM-host server. Usually, I just use the virt-manager gui application to create this task. However, I’d like to do this via command line this time. Why? Well, why not? It’s always fun to learn new thing. :) libvirt keeps network configuration in XML files under /etc/libvirt/qemu/networks/. Here is what I have on one of my machines: # ls -1 /etc/libvirt/qemu/networks/*xml /etc/libvirt/qemu/networks/classroom....
Last night I published 4 or 5 of blog posts related to the Foreman/Satellite server. Well, it wasn’t a coincidence, it was me cramming the last minute for the Red Hat Satellite 6 Administration exam today. It’s also known as EX403. Needless to say, I didn’t know what was in the exam, and I can’t share what was in exam I had taken today. What I can share with you is that I passed EX403!...
In this blog post, I’m going to practice publishing and promoting content views using the hammer CLI. I already know how to do this using the Satellite/Foreman web UI. First, I’m going to create the Base content view for Operations organization and Boston location. [root@foreman ~]# hammer content-view create \ > --name Base --organization Operations \ > --description 'Base Packages' Content view created. [root@foreman ~]# hammer content-view list --organization Operations ----------------|---------------------------|--------------------------|-----------|---------------------|--------------- CONTENT VIEW ID | NAME | LABEL | COMPOSITE | LAST PUBLISHED | REPOSITORY IDS ----------------|---------------------------|--------------------------|-----------|---------------------|--------------- 6 | Base | Base | false | | ----------------|---------------------------|--------------------------|-----------|---------------------|--------------- The next step is adding the repos to the content view....
In this post, I will create a new life-cycle environment paths for the Operations organization that includes life-cycle environments named Deveopment, QA, and Production. Let’s list the current life-cycle environment for Operations organization. [root@foreman ~]# hammer lifecycle-environment list --organization Operations ---|---------|------ ID | NAME | PRIOR ---|---------|------ 6 | Library | ---|---------|------ When we create our first environment, we’ll need to use the ID of the Library, which is 6 in this case....
In this blog post, I’m going to show how to add a new product caled EPEL8 and populate it with a repository from EPEL 8. There should be 3 main steps: Create a Content-Credentials which stores the package signing key of the product or repository Create a new Product Create a new Repository Firt thing first, let’s create a new content-credentials named RPM-GPG-KEY-EPEL-8 with the contents from the EPEL 8’s GPG signing key....
Let’s learn how to create an organization and location on Foreman/Satellite server using the hammer command-line-interface. In this example, I’m going to create an organization called: Operation and assign its location to Boston. On the Foreman server, excute the following commands: [root@foreman ~]# hammer organization create --name Operations Organization created. [root@foreman ~]# hammer location create --name Boston Location created. [root@foreman ~]# hammer organization add-location --name Operations \ > --location Boston The location has been associated....
