Cisco Certifcations

There are a ton of useful websites for whatever Cisco certification you are persuing.  I just stumbled on another via a Cisco Support Forum.  http://www.ine.com  Very reasonable prices and highly recommended.  Not by me, but by engineers that have already used them for certification.  I plan on purchasing the CCNP package.

Fedora 14 - Virtual Box Extentions

I was having issues getting the Virtual Box extensions to install into Fedora 14.  (Window host system).  I found one forum entry that fixed my issue.  The command, and link are below.

yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel

The above command must be run as root (su) prior to installing the extensions.  It installs the kernel headers required by the extensions package.
