FreeBSD - How to disable or turn off the keyboard beep sound

A reminder to myself on how to disable the keyboard beep sound (serve as an alert) when ever an error occured in the console command line. It is control by a sysctl value. To stop it now on all console, execute :

sysctl hw.syscons.bell=0

To make it permanent, such as every time FreeBSD boots, disable the beep sound :

echo "hw.syscons.bell=0" >> /etc/sysctl.conf

Alternately, to disable only this console :

kbdcontrol -b off

Vaarwel !!!
