NetworkManager Sound Notifications

[madjoe]

I think it would be quite nice if we could configure NetworkManager to play a custom audible notification (wav file) upon establishing Internet connection and upon disconnecting from the Internet as well. Is there any workaround for this feature yet?

For those who would like to enable this feature, here's a workaround:

• http://bpaste.net/show/9289/ -- save that as /etc/NetworkManager/dispatcher.d/99playsound and chmod +x it.
  
• Edit the last 4 lines to tell it what to do.

Usecase:
If you are dealing with poor WiFi connection, downloading something and if you're afk, probably you'd like to know when your Internet connection goes offline (if you're close enough to hear a sound notification, of course).

# proc folder of nm-applet and copy its environment. Also setuid to the
# correct user so gnome-keyring accepts the connection
for d in os.listdir('/proc'):
    if not d.isdigit():
        continue
    d = os.path.join('/proc', d)
    try:

...
if sys.argv[2] != 'up':
    subprocess.call(['/usr/bin/paplay','/home/madjoe/down.wav'])
else:
    subprocess.call(['/usr/bin/paplay','/home/madjoe/up.wav'])

Did you replace '/home/madjoe/down.wav' and '/home/madjoe/up.wav' with your own files?

Did you save the script as /etc/NetworkManager/dispatcher.d/99playsound ?

If so, in terminal:
sudo chmod +x /etc/NetworkManager/dispatcher.d/99playsound

This sets it as an executable file, which allows it to run as a script.
