Hi there

I'm Louis Abel. I'm originally a System Administrator, turned System Engineer, turned... I'm not sure anymore. I wear a lot of hats these days. Either way, I want to thank you for stopping by!

What do you work on?

I work on too many things to remember or count. The primary things I work on though these days would be:

• Ansible stuff
• My own FreeIPA adventures
• My own Fedora system when it misbehaves
• Some gzdoom builds (when they have releases)
• Maintaining some python and powershell scripts, Windows images (for my own sanity)
• Light maintaining of a wiki with some Enterprise Linux and Fedora stuff

What do you do in your free time?

I work on my music or I go to one of my few go-to games at my disposal, such as StarCraft, Guilty Gear Strive, gzdoom, and Overwatch. If you would like to play StarCraft (brood war/remastered) or Guilty Gear Strive, I am always open! You can find me on the US West regions.

Move away from Grunt

The grunt plugins are outdated and some of them contain vulnerabilities. Besides, we can just do what it's doing under the hood using some sort of script.

Change fonts or find faster way to load fonts

By far the most bandwidth intensive part is loading all of the fonts. Think the simplest solution is just to change the font stack.

FreeIPA/macOS PAM configuration and UI privilege elevation

In el/freeipa.rst → Client Setup → Mac Clients: it might be worth noting that the PAM configuration shown can interfere with the macOS GUI's privilege elevation system. For example, in the following sequence assume we have a Mac with a local admin user, configured to authenticate against FreeIPA as shown.

1. Log in as a FreeIPA user without admin status. Use klist to note the Kerberos tickets.
2. Open the System Settings, and do something that requires local admin privileges (or try to install an application).
3. Authenticate as the admin.
4. Check klist again -- note that the default ticket cache has been changed. Running kinit is needed to get back to the FreeIPA user's tickets.

As a workaround for this, on my Mac I use the default PAM configuration files and a third party tool to obtain a TGT on login (io.github.hamstergene.ticket-renewer -- I'm not aware of any other such tools, or something like sss built in to macOS). Downside is this requires manual password sync, but I find it's needed anyway even with PAM adjustments to refresh the tickets perodically.

Use npm-ci and caching to speed up builds

Add information on password management anti-patterns

Fix lack of certificate for www

Visiting https://www.linuxguideandhints.com/ still gives an error because the certificate for www is expired. In theory, there should be an automatic redirect but there isn't one. We may need to follow the documentation for setting up an apex domain for this to work correctly.

Remove outdated articles/information

Update backup article

It is outdated.

Add information on content security policy and javascript

Fix how the site looks on mobile

In removing some stuff we removed mobile compatibility, add it back in some way.

Can you please tell me where you found all those pxelinux.* dhcp options?

I understand what a class is (it's a namespace), but I have been hitting my head on my desk trying to figure out where those pxelinux.* options come from. Is there a central place where people keep track of all the dhcp namespaces available?
