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)
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).
How To Set Up Apache2 With mod_fcgid And PHP5 On Ubuntu 11.10
This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on Ubuntu 11.10. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.
The Perfect Desktop - Ubuntu 12.04 LTS (Precise Pangolin)
This tutorial shows how you can set up an Ubuntu 12.04 (Precise Pangolin) desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.
The Perfect Server - Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3)
This tutorial shows how to prepare an Ubuntu 12.04 LTS (Precise Pangolin) server (with Apache2, 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 Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).
How To Upgrade Ubuntu 11.10 (Oneiric Ocelot) To 12.04 LTS (Precise Pangolin) (Desktop & Server)
The new Ubuntu 12.04 LTS (Precise Pangolin) has just been released. Ubuntu 12.04 LTS is a long-term support release, which means it is supported for five years. This guide shows how you can upgrade your Ubuntu 11.10 desktop and server installations to Ubuntu 12.04 LTS.
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)
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
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.
