Create And Restore Partition Images With Partimage

Fri, 18 May 2012 16:17:30 +0200

Create And Restore Partition Images With Partimage

Backups are usually made in one of two ways - either file-based which means that single files are backed up, often via synchronization and on an external disk, or image-based which means that a whole partition is stuffed into an image file that can be restored on the partition, containing everything there was on it. This tutorial covers image-based backups using Partimage from a live desktop environment.

How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04

Wed, 16 May 2012 18:04:15 +0200

How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04

This document describes how to add WiKID two-factor authentication to Apache 2.2.22 using mod_auth_radius on Ubuntu 12.04. It is also recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.

Running OXID eShop Community Edition (Version 4.5.9) On Nginx (LEMP) on Debian Squeeze/Ubuntu 11.10

Tue, 15 May 2012 17:50:39 +0200

Running OXID eShop Community Edition (Version 4.5.9) On Nginx (LEMP) on Debian Squeeze/Ubuntu 11.10

This tutorial shows how you can install and run OXID eShop Community Edition (version 4.5.9) on a Debian Squeeze or Ubuntu 11.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). OXID eShop is a feature-rich ecommerce platform; I will use the Community Edition here which is licensed under an open source certified license (GPL v3.0). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.0.x On Debian Squeeze

Mon, 14 May 2012 17:56:14 +0200

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.0.x On Debian Squeeze

This tutorial shows how to set up a standalone storage server on Debian Squeeze. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

How To Back Up MySQL Databases With mylvmbackup On Debian Squeeze

Wed, 09 May 2012 17:49:37 +0200

How To Back Up MySQL Databases With mylvmbackup On Debian Squeeze

mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on a Debian Squeeze server.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 12.04 LTS)

Tue, 08 May 2012 19:31:22 +0200

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 12.04 LTS)

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, 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.

Encrypt Your Data With EncFS (Debian Squeeze/Ubuntu 11.10)

Mon, 07 May 2012 18:16:15 +0200

Encrypt Your Data With EncFS (Debian Squeeze/Ubuntu 11.10)

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Debian Squeeze/Ubuntu 11.10 to encrypt your data.

The Perfect Server - Ubuntu 12.04 LTS (nginx, BIND, Dovecot, ISPConfig 3)

This tutorial shows how to prepare an Ubuntu 12.04 LTS (Precise Pangolin) server (with nginx, BIND, Dovecot) 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 or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers nginx (instead of Apache), BIND (instead of MyDNS), and Dovecot (instead of Courier).

Proxmox VE 2.x With Software Raid

Proxmox Virtual Environment is an easy to use Open Source virtualization platform for running Virtual Appliances and Virtual Machines. Proxmox does not officially support software raid but I have found software raid to be very stable and in some cases have had better luck with it than hardware raid.
