Quick Warning:
To those that run your own webservers, and Mac OSX users.. If you haven’t already heard, there is a critical exploit out called SHELLSHOCK now that uses exploits a flaw in “bash” the primary command line of unix type operating systems. (linux, *bsd, Mac OSX). A variable can be used to execute a command.
This exploit can also be triggered remotely by making a special request to most webservers that run on linux or *bsd.
I am constantly having to pre-create or migrate massive amounts of LUNs in customer environments. I have many ways to go about it, powershell, ruby, but my awk script is my #1 way to do it
Imagine having to make luns for dozens of database instances on multiple hosts for dev/prod/qa. Suckage!
They all would follow a certain order and naming convention. Most of the sizes would be the same.
If I have to do anything once, I’ll probably have to do it again. So, script it! This will work in any shell with awk (osx/linux/solaris/CygWin)

Enter the SSH KEYs. Here is how to set them up on your NetApp in both 7-mode and Cluster Mode!

First off, let me say that I live and breathe the terminal. Almost 2 decades playing in unix and linux gives me a strong love for it. I know I am more productive than a pointy clicky loser. BASH ftmfw! (and when I am stuck admin’ing windows systems, powershell, which I am not ashamed to say I have a newfound fondness for.)

So, you are studying for a networking certification. Maybe CCNA or CCNP, maybe F5 or Juniper. You need multiple interfaces to run GNS3/Dynamips or your favorite networking tool. Alas, the default configuration of VMWare Fusion just has the basic VMnet1 and VMnet8. Here is how to fix that!
