OEL/RedHat Server Setup

sudo dnf update -y
sudo dnf install -y epel-release
sudo dnf groupinstall -y "Xfce" "base-x"
sudo dnf install tigervnc-server firefox
sudo id support
echo ":1=support" | sudo tee -a /etc/tigervnc/vncserver.users
sudo su - support -c "vncpasswd"
sudo systemctl enable --now vncserver@:1
sudo firewall-cmd --add-port=5901/tcp --permanent
sudo firewall-cmd --reload

Session setup (/home/support/.config/tigervnc/config)

session=xfce
geometry=1920x1080
alwaysshared
interface=127.0.0.1

VNC connection

vncviewer -passwd /home/jump/.config/tigervnc/passwd -via server_address_ip 127.0.0.1:5901 

Pipewire+pipewire-pulse already up and running.

“Local” side

pactl load-module module-native-protocol-tcp

“Remote” side (inside VNC session in my case)

pactl load-module module-tunnel-sink server=tcp:IP_ADDRESS

Use pavucontrol/etc next.

IMSM versus fakeRAID aka imsm last chance ;) Or how to get Intel VROC with little or no pain (not yet, sorry) ;)

mdadm --create --verbose /dev/md/imsm /dev/sd[ab] --raid-devices 2 --metadata=imsm
mdadm --create --verbose /dev/md/md128 /dev/md/imsm --raid-devices 2 --level 1

Some checkups below (CLI).

Sometimes need some strange things… to do )
