SELinux and Podman
Last time I messed around with Podman, I finally got things working and had what I think was a pretty good understanding of how to go forward. But in order to get things working, I’d had to turn off SELinux. Now it was time to see what I had to do to make Podman work…

Attempting a podman play on another VM
The podman saga continues. The podman equivalent of a docker-compose.yml can be created from a pod with the following command: podman generate kube (name of pod) > (filename).yaml So I did that with the pod that I’d created with an SELinux context. Now it was time to try it on another Fedora 31 VM to…

Followup to Podman and PHPIpam
Adding the –name mysql – it wasn’t enough to get the PHPIpam apache container to find the mysql container. They’re in the same pod, but something’s not quite right. So I decided to see if I could modify the config.php by mounting the container and modifying that. # podman mount beautiful_gauss /var/lib/containers/storage/overlay/5a33decc2cfad7e9bda5f9048d94a814267d954e97d5dd7befb057a84367f27a/merged While this allowed…

Can Docker and Podman both run on the same machine?
I’ve been hearing about Podman for a while now – at Red Hat Summit and at various local Red Hat presentations. I’ve seen the slides where the RHEL presenter (it’s always the same guy, but I’m terrible with names – after a bit of research, I think it’s Dan Walsh) asks you to pledge to…

Playing with Fedora Rawhide
I wanted to play a bit with Fedora Rawhide so I installed Fedora 23 to a VM. I named it Blargg after the Fire Dragon in Super Mario World. (See video below) I used the following commands from the Fedora wiki: # dnf upgrade dnf # dnf install dnf-plugins-core fedora-repos-rawhide # dnf config-manager –set-disabled fedora…

Another Fedora Print Debugging Tip
The wife told me she couldn’t print from her computer. Sure enough, I couldn’t print from mine either. I tried the trick from last time and ran system-config-selinux but selinux wasn’t responsible this time. So I removed the printer and this time I added it through the cups website: localhost:631. After doing that it worked.

Fedora Print Debugging Tip
I was having trouble printing and couldn’t figure out what was going on. I tried everything, including reinstalling the printer and reinstalling the driver. I was getting a misleading “you are using the wrong driver” message. Turns out SELinux was to blame! I happened to check dmesg and see some audit messages. Then I did…

Home Server Project Update 2: Goodbye Arch Linux
As I documented before, I’ve had problems with Pogoplug and Arch Linux running my servers. Recently I’ve been having problems logging in via SSH on my updated Fedora computers. From what I can tell from a little research, it seems the old way of connecting had a flaw so updated SSH doesn’t want talk to…

Preupgrade from Fedora 15 (Lovelock) to Fedora 16 (Verne)
As usual, every time I upgrade Fedora I write a blog post to preserve this knowledge for others who might run across the same problem or in case it happens to me again next year. This time around the situation was a little less smooth than previous upgrades. After the preupgrade was done, when I…

Another Look at KDE and Amarok Part 1
As I’ve mentioned before, I used to be really excited about KDE. It’s been a while since I last looked at KDE. Well, technically, I couldn’t really do much there. But there’s this time I was able to look at it. Let me just say that I no longer agree that it’s uglier than Gnome.…

yum upgrade to Fedora 12 (and mini-review)
So I was unable to preupgrade to Fedora 12, even after the latest update. So I did a yum upgrade since I’ve known that to work in the past. As always, I followed the instructions here. It was very fast this time around compared to past upgrades. It only took 2 hours 40 minutes. I…

Fedora 11 Released!
I missed the release by a couple of days, but as is my tradition, here is the release notice: Ladies and gentlemen of the Royal Explorers Club! Your attention please. It falls to me to be the host of our proceedings to-day, as we celebrate a great achievement in the annals of this hallowed organization…

Some really quick observances about Fedora 8
The bootup screen is pretty, but…. The default GDM screen looks a little ugly to me….perhaps it’s just too new. The new SELinux notification tool may be useful if something is not working correctly, but it just bugs the heck out of me as every single program appears to be trying to access protected memory.…
