A Beginner's Guide To LVM

Posted Tue, 2007-01-16 13:51 by falko

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

Automatically Scan Uploaded Files For Viruses With php-clamavlib

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

How To Use NTFS Drives/Partitions Under Ubuntu Edgy Eft

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 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

Tunneling MySQL connections through SSH

Posted Tue, 2007-01-02 14:44 by falko

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
