[oclug] Auto ifdown / ifup

[Dan Cardamore]

Your server may go down from the outside world if you don't initiate a
connection from the inside peridically.

If you ping your router every minute, you may find that you stay up.

    /bin/ping -i 60 router > /dev/null &

This is because the cable modem stops listneing to the outside world
unless it thinks you are using your computer.
