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

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.

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.

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)

Sun, 06 May 2012 20:29:22 +0200

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).

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

Tue, 24 Apr 2012 15:55:10 +0200

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 11.10) with GlusterFS. The client system (Ubuntu 11.10 as well) 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.

Maintaining Remote Web Sites With sitecopy (Debian Squeeze/Ubuntu 11.10)

Sun, 22 Apr 2012 19:54:53 +0200

Maintaining Remote Web Sites With sitecopy (Debian Squeeze/Ubuntu 11.10)

sitecopy is a tool for copying locally stored web sites to a remote web server (using FTP or WebDAV). It helps you to keep the remote site synchronized with your local copy by uploading modified local files and deleting remote files that have been deleted on the local computer. This tutorial shows how you can manage your remote web site from your local Debian Squeeze/Ubuntu 11.10 desktop with sitecopy.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

Tue, 17 Apr 2012 18:32:23 +0200

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

This tutorial shows how to combine four single storage servers (running Ubuntu 11.10) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work.
