For anybody looking to install Linux from a USB stick, I would recommend taking a look at http://unetbootin.sourceforge.net/, it worked a treat for me with Ubuntu server 8.04.
I’ve recently setup a new home linux server to act as an email, media and development server, the final piece of the puzzle was to setup relatively secure remote access which can be connected to easily from anywhere – My preferred method for this is using a PPTP VPN.
I’ve configured several servers with PPTP support, but I always lose the link to the distro specific downloads, so future reference here they are http://poptop.sourceforge.net/yum/stable/packages/
If your looking for a good tutorial on configuring PPTPD on Centos 5, check out this tutorial by Win Loon.
