• Entering A Safe Mirror When Logging In With Unionfs And Chroot

  Author: stefbon • Tags: other, security, storage • Comments: 1

  Entering A Safe Mirror When Logging In With Unionfs And Chroot When reading a 'hint' on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted homedirectory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is a exact copy (mirror) of the system you're working on. Because you're in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).

• Creating A Fully Encrypted Para-Virtualised Xen Guest System Using Debian Lenny

  Author: andreash • Tags: debian, security, virtualization, xen • Comments: 4

  Creating A Fully Encrypted Para-Virtualised Xen Guest System Using Debian Lenny This document explains how to set up a fully encrypted para-virtualized XEN instance. In this howto, the host system is running Debian Etch, while the guest system to be installed will be using Debian Lenny. If you are concerned about your privacy, you might want to consider using hard disk encryption to protect your valuable private data from spying eyes. Usually, the easiest way would be to use your distribution's installer to set up a fully encrypted system; I think most recent Linux distributions support this. However, when you are using XEN to provide virtualization, there are situations where you might not want to encrypt your whole computer with all guest instances, but instead only encrypt one OS instance. This howto will deal with exactly this situation. It assumes that the XEN host system is already up and running.
