Fedora kiosk

Submitted by gill on

Install gnome kiosk (gdm, zenity, and firefox should already be installed).

sudo dnf install -y gnome-kiosk-script-session

Create the user and give them a password.

sudo useradd -c "TV user" -m tvuser

sudo passwd tvuser

Modify the GDM configuration to automatically login the user on startup. Edit /etc/gdm/custom.conf to add these:

[daemon]
AutomaticLoginEnable=True
AutomaticLogin=tvuser

Manage podman with systemd

Submitted by gill on

After getting the containers running you can have systemd start and stop them for you.

$ podman pull docker.io/library/httpd

$ podman run -dt -p 8080:80/tcp --name httpd docker.io/library/httpd

Now you can create systemd files:

$ cd $HOME/.config/systemd/user

$ podman generate systemd --new --files --name httpd

The podman generate command creates a systemd service file named container-httpd.service. Reload the daemon to read the new file:

$ systemctl --user daemon-reload

Stop the running container

Permanently enable wake-on-lan with nmcli

Submitted by gill on

First, check that the interface supports WoL:

sudo ethtool enp4s0 |grep Wake
    Supports Wake-on: g
    Wake-on: d

Supports Wake-on: g is required for WoL to work. You can change the setting with ethtool or NetworkManager. When you use ethtool, the change does not survive a reboot.

sudo ethtool -s enp4s0 wol g

By using Network Manager nmcli commands, the change persists reboots.

Workload Scheduler power users: You need rlwrap

Submitted by gill on

If you use the Linux shell very much, you find its history functions very useful. You can recall previous commands very easily, just using the arrow keys.
If you use the Workload Scheduler command-line interfaces, conman and composer, you really miss the history. Sure there's the redo command, but its editing capability is limited to the last command you typed.
