Most videos on Youtube play well, but some don't, sor example, this one - https://www.youtube.com/watch?v=hDcc0g03H28
You need to install ffmpeg-libs from a third party repo like rpmfusion to make firefox play H.264 encoded videos.

Re: udev hotplug ethernet , show ifdown (4G Dongle)

You are not supposed to write a udev rule for usb_modeswitch. You just install the usb_modeswitch package and that's it. What also doesn't work is ONBOOT=yes and usb network devices.

Is TCP Wrappers enabled by default on CentOS?
A TCP Wrappers package is not even available in CentOS 8.
