Hack and / - Lightning Hacks—the Command Next Door
The problem with powerful server hardware is that it always takes a little time to reboot. Often when I have to reboot a server, I want to know the moment it comes back up, because I want to log back in and finish some work. Usually when I reboot a machine, I start a ping process, so I can watch to see when it is available. The problem is that servers seem to take just long enough to come back up that I end up getting distracted in another window on my desktop and don't see the ping replies. My solution to this is to make ping audible:
$ ping -a 10.0.1.7
When you pass the -a command to ping, it generates an audible bell for every ping reply. I get to hear a few system beeps as the server goes down, and then I hear only silence. If I do become distracted and the server comes back, I immediately start hearing this annoying system beep in my ear and know the server is ready.
