Xen and the Art of Virtualization
09/01/2005 at 12:00 AM
One of the hot topics at this year’s Linuxworld conference was virtualization, the abstraction of hardware to provide higher utilization, increased availability and easier management.
The open source Xen project (http://www.xensource.com/) provides software that partitions a physical server into several virtual servers. Xen uses a unique approach they call “para-virtualization” that provides much better performance than other virtual pc systems. Xen has been accepted into the mainline Linux kernel and is being embraced by the Linux community. For more information look at:

I will talk about the ideas of server and data center virtualization and demonstrate using Xen to run several virtual machines on a server. If I can get it to work, I will show the live migration of a running virtual machine from one system to another without interrupting running programs.

M0n0wall
07/07/2005 at 12:00 AM
Jed Reynolds will present a demonstration about the FreeBSD based firewall, m0n0wall. M0n0wall is a run-from CD firewall that can save it’s rules to floppy or usb, and wieghs about 10mb. Jed will demonstrate how to get started with it using it’s slick PHP based interface, and point out advanced features, like traffic shaping, VPN, and DHCP options.
Disk Based Backup with Rsync, Ssh and Dirvish
06/02/2005 at 12:00 AM
With the cost of disk drives becoming so cheep, many users are ditching slow and expensive tape based backup systems and replacing them with disk based backup.
I will talk about 3 linux based programs that can be used for disk based backup, rsync, a fast incremental file transfer program created by Andrew Tridgell of Samba fame. Ssh a secure network communication program, and dirvish, a perl script that automates network backups using rsync and ssh. If time permits, I will also go over configuring dirvish to work with Bran Hatch’s authprogs
program to create secure unattended network backups.

Increasing performance with rzip, z7a and lzop
03/03/2005 at 12:00 AM
How to use little known, but top performing, lossless data compression utilities to increase backup and bandwidth capacities by up to 400%.
While Linux’s best known data compressors may be “gzip” and “bzip2”, my research has found that
“lzop” is faster, “7za” compresses more, and “rzip” achieves some of both with extra memory, which is becoming more and more affordable.
Kingsley has been using computers for twenty nine years and Linux for eight . I’ve worked at IBM and Hewlett Packard and have written articles for Byte magazine, the L.A. Daily Journal and the First International Conference on Neural Networks.
http cache and expiration headers
02/03/2005 at 12:00 AM
Michael Titus will give a short presentation on HTTP cache and expiration headers that can be used to improve browser performance and reduce server workloads. This presentation should be of interest to Apache administrators and to web developers using Java, PHP, and Perl.
