A new post, a new problem, and a solution. Earlier today I worked on a task involving SSSD, System Security Services Daemon, a system service to access remote directories and authentication mechanisms. It got both excited and a little worried at the same times, since it’s been a long while since I had do anything with SSSD. Fast forward to the evening, I realized I had a FreeIPA server set up a long time ago right after passing the Red Hat Certified Specialist in Identity Management exam (EX362)....

A few days ago I started to re-surrect my Foreman(/katello) server and wanted to use it to pull content from remote repository for AlmaLinux. This involves updating Foreman with a new product and related AlmaLinux repository. I wrote a similar post on creating product & repository using hammer before for EPEL 8. However, it’s been a long while and things could change with the current version of Foreman server. # rpm -qa | egrep -i '^foreman-[0-9]|^katello-[0-9]|^pulp-server-[0-9]' katello-4....

When I logged into to the server, I saw a message complaining that bash: append_path: command not found. It’s been so long since this little server, so I can’t remember what happened last time....

I haven’t really posted anything new recently as I’ve just had a big transision in my career. I may or may not write about this in the future, as I don’t think it’s that relevant to you. Anyway, I’ve been having this trouble with window size of Alacritty being too small on launched.First what is Alacritty? It’s an terminal emulator written in Rust. It also makes use of GPU-acceleration, which should improve some performance in theory....
