Welcome back for another episode of the ABC's of NSM.  What's NSM you say?  We'll go with Network and System Management, but you could throw Security in there as well.  We'll work our way through the alphabet over the next several weeks looking at tools and concepts along the way for all the administrators out there.abc_2_4   By the way, you can thank Joe for the format & Don for the title (I  couldn't for the life of me come up with one.)   

Today's letter K is for Knoppix.  Knoppix is no longer unique now that pretty much every linux distribution has their own version of a live CD, but it was one of the pioneers in this space.  A live CD (and more recently, the live USB) contains a fully bootable operating system, with no requirements that a storage device is present.  This allows users to carry their OS with them without lugging around the hardware.  Visiting friends?  Pop in your live CD and use your OS on their iron with no harm done.  Experience the blue screen of death one too many times and your OS no longer boots?  Slap Knoppix in the drive and mount your hard drive to recover the data.  Want to try out a new linux distribution without committing to it?  I recently downloaded MacPup Foxy for an older laptop, and played with it for a few hours before continuing on to an install--very handy.  The live CD/USB route has dozens of great use cases, several of which (thank you Knoppix, though there are several other worthy options) have saved me over the years.
