Using iSCSI On Debian Lenny (Initiator And Target)

Using iSCSI On Debian Lenny (Initiator And Target)

This guide explains how you can set up an iSCSI target and an iSCSI initiator (client), both running Debian Lenny. The iSCSI protocol is a storage area network (SAN) protocol which allows iSCSI initiators to use storage devices on the (remote) iSCSI target using normal ethernet cabling. To the iSCSI initiator, the remote storage looks like a normal, locally-attached hard drive.

Measuring Linux Latency With LatencyTOP On Ubuntu 8.10 And Debian Lenny

Measuring Linux Latency With LatencyTOP On Ubuntu 8.10 And Debian Lenny

LatencyTOP is a tool that lets you identify where in the system latency is happening, and what kind of operation/action is causing the latency to happen. This article shows how you can use LatencyTOP on Ubuntu 8.10 and Debian Lenny.

How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)

How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)

This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V). Hardware virtualization allows you to install unmodified guest systems (in contrast to paravirtualization where the guest kernel needs to be modified); that way you cannot only virtualize OpenSource operating systems like Linux and BSD, but also closed-source operating systems like Windows where you cannot modify the kernel.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Lenny)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Lenny)

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

NIC Bonding On Debian Lenny

NIC Bonding On Debian Lenny

Ethernet bonding refers to aggregating multiple ethernet channels together to form a single channel. This is primarily used for redundancy in ethernet paths or for load balancing. This page refers in particular to performing ethernet bonding under Linux, and so does not limit itself to discussion of 802.3ad Trunk Aggregation.

Xen Cluster Management With Ganeti On Debian Lenny

Xen Cluster Management With Ganeti On Debian Lenny

Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.

DRBD 8.3 Third Node Replication With Debian Etch

DRBD 8.3 Third Node Replication With Debian Etch

The recent release of DRBD 8.3 now includes The Third Node feature as a freely available component. This document will cover the basics of setting up a third node on a standard Debian Etch installation. At the end of this tutorial you will have a DRBD device that can be utilized as a SAN, an iSCSI target, a file server, or a database server.

Installing And Using OpenVZ On Debian Lenny (AMD64)

Installing And Using OpenVZ On Debian Lenny (AMD64)

In this HowTo I will describe how to prepare a Debian Lenny server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Getting High With Lenny

Getting High With Lenny

The aim here is to set up some high available services on Debian Lenny (at the time of writing still due to be released). Most of the documentation available for such a setup I found on the net are based on Xen but I prefer to use Vserver for the "virtualisation" because of its configurability, shared memory and cpu resources and basically the raw speed. DRBD8 and Heartbeat should take care of the availability magic in case a machine shuts down unexpectedly.

The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3]

The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3]

This tutorial shows how to prepare a Debian Lenny (Debian 5.0) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.
