My God! It's full of stars!

Ever try hooking up a server or firewall with multiple network cards? You stand in back of it wondering which RJ45 port is eth0, which one is eth1...

Here's a little tip: you can make network card lights blink with the ethtool command:

ethtool -p eth0

You can make each card blink for 30 seconds in order with something like:

for net in eth0 eth1 eth2; do ethtool -p $net 30; done
