function to verify an IP address - can be used at the shell prompt or in a shell script

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

pretend to be busy in office to enjoy a cup of coffee
This will turn it in an infinite loop and also shows random words from a file, so it won't be the same each time and also not just a number.

Force machine to reboot no matter what (even if /sbin/shutdown is hanging)
This will cause your machine to INSTANTLY reboot. No un-mounting of drives or anything. Very handy when something has gone horribly wrong with your server in that co-location facility miles away with no remote hands! Suspect this works with all 2.2, 2.4 and 2.6 Linux kernels compiled with magic-syskey-request support.
