Comments: 0 Virtualization With KVM On An OpenSUSE 12.1 Server This guide explains how you can install and use KVM for creating and running virtual machines on an OpenSUSE 12.1 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

How To Configure PureFTPd To Accept TLS Sessions On CentOS 6.2

Comments: 0 FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to configure PureFTPd to accept TLS sessions on a CentOS 6.2 server.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On CentOS 6.2
Author: Falko Timme •

Comments: 1 Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On CentOS 6.2 This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database. This tutorial is based on CentOS 6.2.

Using ATA Over Ethernet (AoE) On Debian Squeeze (Initiator And Target)
Author: Falko Timme •
Tags: debian, storage •
Comments: 0 Using ATA Over Ethernet (AoE) On Debian Squeeze (Initiator And Target) This guide explains how you can set up an AoE target and an AoE initiator (client), both running Debian Squeeze. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

Server Monitoring With munin And monit On Debian Squeeze

Comments: 0 Server Monitoring With munin And monit On Debian Squeeze In this article I will describe how you can monitor your Debian Squeeze server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems, and a watchdog that ensures the availability of the monitored services.

How To Save Traffic With nginx's HttpGzipModule (Debian Squeeze)
Author: Falko Timme •
Tags: debian, nginx, web server •
Comments: 0 How To Save Traffic With nginx's HttpGzipModule (Debian Squeeze) In this tutorial I will describe how to configure HttpGzipModule on an nginx web server (on Debian Squeeze). HttpGzipModule allows nginx to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With HttpGzipModule, you can compress HTML, CSS, Javascript, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.
