Sends random sounds to your sound card output (e.g. your speaker). Think... You can also run it remotely on another computer using SSH and scare its user!

Sends random beeps to your PC-speaker. Think... You can also run it remotely on another computer using SSH and scare its user! Don't forget to run it on your dedicated hosting server and watch sysadmin's action from data-center's live remote cameras!

This command will disable the beep sound from the PC speaker.

To ensure that it will never come back, you can edit /etc/modprobe.d/blacklist

Add "blacklist pcspkr" sans quotes

while true; do [ "$(ping -c1W1w1 server-or-ip.com | awk '/received/ {print $4}')" != 1 ] && beep; sleep 1; done

pings a server once per second, and beeps when the server is unreachable.

Basically the opposite of:

ping -a server-or-ip.com

which would beep when a server IS reachable.

You could also substitute beep with any command, which makes this a powerful alternative to ping -a:

while true; do [ "$(ping -c1W1w1 server-or-ip.com 2>/dev/null | awk '/received/ {print $4}')" = 1 ] && date || echo 'server is down!'; sleep 1; done

which would output the date and time every sec until the ping failed, in which case it would echo.

Notes:

Requires beep package.

May need to run as root (beep uses the system speaker)

Tested on Ubuntu which doesn't have beep out of the box...

sudo apt-get install beep
