[ale] Dual NICs

[ChangingLINKS.com]

<start eyeofthetiger.wav>
Hear me roar: Roar!
I 'so' got the bond0 thingy working. I call this configuration "Dual NICs." It
sounds like power, it smells like power, it tastes like power. And, most
importantly, it looks cool! I have both nics attached to the same switch, so I
feel like I have put on of those bigger tail pipes on my 1.8 liter Neon.
Recognize that lots of those tailpipes sell.

Will I have to add liquid cooling to keep the surface tempurature of the nic
cards down? Will my isp throttle me down so the rest of Texas can still use 
the
Internet? I am not sure - all I know is now that I got the "Dual NIC"
configuration, if one of my cards goes bad, the other one is still truckin' . 
.
. and that means "power!"

I don't know IF I will be able to sleep tonight.

Thanks, Chris for teaching a man to fish.
