Linux-VServer is a jail mechanism in that it can be used to securely partition resources on a computer system (such as the file system, CPU time, network addresses and memory) in such a way that processes cannot mount a denial-of-service attack on anything outside their partition.

Each partition is called a security context, and the virtualized system within it is the virtual private server. A chroot-like utility for descending into security contexts is provided. The contexts themselves are robust enough to boot many Linux distributions unmodified, including Debian and Fedora Core.

Virtual private servers are commonly used in web hosting services, where they are useful for segregating customer accounts, pooling resources and containing any potential security breaches.

Über den Autor Herbert Pötzl:

Born in 1970, explored the world of integrated circuits
at the age of 10, implemented his first 'computer' game
on a self built micro computer in 1981 (The Game of Nim)
Later switched to consumer electronics, C64, C128 and
finally Amiga, developed numerous useless applications
mainly in assembler language, until confronted with the
colorless non intuitive PC, as a natural result, lost
for some time in DOS and 8086/88 assembler, trying to
write a useful operating system with a gui. This effords
where dropped intantly in 1991 as his computer science
studies got him access to a NeXT system which at this
time was more advanced than everything else available.
Prepared a course for students and taught some years
object oriented Software Engineering at the Technical
University of Vienna. Got first contact with Linux at
the University and later, as OpenStep was discontinued
slowly moved to the beautiful world of Linux and free
software. While working for several smaller and some
larger companies in Austria, studied the unix working
environment, kernel concepts and later internals.
Since November 2003 Project Leader of Linux-VServer,
after more than a year of vserver development.
