This guide covers the installation of XenExpress and the creation of virtual machines with the XenServer Administrator Console. XenExpress is the free virtualization platform from XenSource, the company behind the well known Xen virtualization engine. XenExpress makes it easy to create, run and manage Xen virtual machines with the XenServer Administrator Console. XenExpress can run up to 4 virtual machines at the same time with a max. total amount of 4GB RAM. The XenExpress installation CD contains a full Linux distribution which is customized to run XenExpress. http://www.howtoforge.com/virtualization_with_xenexpress
This article describes how to install the new native Linux Flash Player 9 from Adobe on an Ubuntu Edgy Eft desktop so that it can be used within Firefox. The procedure works for other Ubuntu versions and Debian as well. http://www.howtoforge.com/native_linux_flash_player9_in_ubuntu
This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast. http://www.howtoforge.com/linux_lvm
This guide describes how you can automatically scan files uploaded by users through a web form on your server using PHP and ClamAV. That way you can make sure that your upload form will not be abused to distribute malware. To glue PHP and ClamAV, we install the package php5-clamavlib/php4-clamavlib which is rather undocumented at this time. That package is available for Debian Etch and Sid and also for Ubuntu Dapper Drake and Edgy Eft. http://www.howtoforge.com/scan_viruses_with_php_clamavlib
Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, CDs, ZIPs, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links and extended attributes, remote backup using pipes and external command (such as ssh), and rearrangement of the “slices” of an existing archive. It can now run commands between slices, encrypt archives, and quickly retrieve individual files from differential and full backups. Dar also has external GUI like kdar for Linux,thanks to the well documented API. Full Story
qmail is a mail transfer agent that runs on Unix. It was more secure replacement for the popular Sendmail program. The author offered a $500 prize for the first person to publish a verifiable security hole in the latest version of the software. This is a useful thing to do in a number of situations. For instance, if you are hit with a spamming attack, you can temporarily instate a second Qmail installation (once the spam run is finished), allow it to take over mail receipt,and then use this tool to clean the offending mails out of the queue before switching over to the main Qmail installation once again.

This tutorial shows how you can back up and restore hard drives and partitions with Ghost4Linux. Ghost4Linux is a Linux Live-CD that you insert into your computer; it contains hard disk and partition imaging and cloning tools similar to Norton Ghost. The created images are compressed and transferred to an FTP server instead of cloning locally. http://www.howtoforge.com/back_up_restore_harddrives_partitions_with_ghost4linux
This article is about resizing ext3 partitions without losing data. It shows how to shrink and enlarge existing ext3 partitions and how to merge two ext3 partitions. This can be quite useful if you do not use LVM and you realize that your existing partitioning does not meet your actual needs anymore. http://www.howtoforge.com/linux_resizing_ext3_partitions
I believe that today Ubuntu has come to a state that makes it easy to install and use by any computer user. If you can work with Microsoft Windows, you should have no problem working with Ubuntu. The transition from Windows to Ubuntu might take a short time of adjustment, but by any standard it is not a difficult transition. Ubuntu is built to be easy as possible, and it gets easier from day to day. In addition the web community is very supportive, and it is easy to find on-line help whenever a problem oucers. I will try to explain some of the stuff that beginners need to now in my new blog: http://ubuntua2z.blogspot.com . My guides will be written with the less technically inclined computer users in mind. I will also use http://www.ubuntux.org as place to exchange ideas about these issues with my peers.
Normally Linux systems can only read from Windows NTFS partitions, but not write to them which can be very annoying if you have to work with Linux and Windows systems. This is where ntfs-3g comes into play. ntfs-3g is an open source, freely available NTFS driver for Linux with read and write support. This tutorial shows how to install and use ntfs-3g on an Ubuntu Edgy Eft desktop to read from and write to Windows NTFS drives and partitions. It covers the usage of internal NTFS partitions (e.g. in a dual-boot environment) and of external USB NTFS drives. http://www.howtoforge.com/ubuntu_edgy_eft_ntfs_ntfs_3g
This tutorial shows how to create a Debian/Ubuntu mirror for your local network with the tool apt-mirror. Having a local Debian/Ubuntu mirror is good if you have to install multiple systems in your local network because then all needed packages can be downloaded over the fast LAN connection, thus saving your internet bandwidth.http://www.howtoforge.com/local_debian_ubuntu_mirror
Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

This is a description of how to set up a secure tunnel between your MySQL Server and a locally running MySQL Administrator using Putty. By creating a secure tunnel to your MySQL server using Putty, you can grant localhost access to powerful applications like MySQL Administrator while at the same time, make your server appear as if it is not even there. In effect, make your MySQL server disappear from the outside world. http://www.howtoforge.com/secure_mysql_connection_ssh_tunnel
Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for telnet, rlogin, rsh, and rcp. For SSH2, there is a replacement for FTP: sftp.This might be useful if you are trying to connect everytime to your server remotely. SSH your Debian servers without password
