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

Posted Sun, 2007-01-14 15:48 by falko

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

Delete Qmail Server messages Queue

Posted Fri, 2007-01-12 11:50 by gg234

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.

Ubuntu is ready for any computer user

Posted Mon, 2007-01-08 05:25 by Hezy

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.

Posted Sun, 2007-01-07 15:04 by falko

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 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

Change your Network card MAC ( Media Access Control) address Using macchanger

Posted Thu, 2007-01-04 14:13 by gg234

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.
