|This tutorial shows how to set up a CentOS 4.5 server that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of CentOS 4.5, but should apply to the 64-bit version with very little modifications as well.|

|Transfer files securely with SFTP|
|File Transfer Protocol (FTP) was once the most widely used protocol for transferring files between computers. However, because FTP sends authentication information and file contents over the wire unencrypted, it's not a secure way to communicate. Secure Copy (SCP) and the more robust SSH File Transfer Protocol (SFTP) address this security concern by providing data transfer over a fully encrypted channel. Full Story|

|Five days with the Classmate PC and Mandriva|
|By: Tina Gasperson
Some say the Classmate PC is Intel's answer to (or competition with) the One Laptop per Child (OLPC) effort. Intel is hawking the lilliputian laptop in "emerging markets" like Nigeria, India, and Mexico as a solution for worldwide education of primary and secondary students. It's to be officially released and shipped en masse to schools in Africa and South and Central America by the end of June. Recently my children and I borrowed a Classmate PC loaded with a custom version of Mandriva Linux. Most of us had fun.

|Retrieving Emails With fetchmail|
|Fetchmail is a program for retrieving emails from remote servers. Imagine you have five email accounts on five different servers. Of course, you don't want to connect to each of them to get your emails. This is where fetchmail comes into play. If you have a user account on a Linux server, you can make fetchmail download emails from remote servers and put them into just one mailbox (the one of your Linux user), from where you can retrieve them with your email client (e.g. Thunderbird or Outlook).|

|Using Ruby On Rails With Apache2 On Debian|
|This article shows how you can install Ruby on Rails (RoR) and integrate it in Apache2 on a Debian Etch system. Ruby on Rails is a web application framework which is rapidly gaining popularity among web programmers. It aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset. Applications using the RoR framework are developed using the Model-View-Controller design pattern.|

|Filesystem Encryption Tools for Linux|
|Crypto filesystems keep your data safe – even if someone steals your computer.Linux offers a number of encrypted filesystem options – each with a different approach to the encryption problem.Encrypted filesystems may be overkill for family photos or your résumé, but they make sense for network-accessible servers that hold sensitive business documents, databases that contain credit-card information, offline backups, and laptops.

|Backing up MySQL data|
|By: Tom Adelstein and Bill Lubanovic
Backing up files and directories is relatively easy; databases, however, have some special quirks that you need to address. Our examples use MySQL, but the same principles apply to PostgreSQL and other relational databases.
This article is excerpted from O'Reilly's recently published book Linux System Administration .

|Open Web Analytics for WordPress|
|By: Joe 'Zonker' Brockmeier
WordPress is a full-featured "personal publishing" platform, but it offers little in the way of traffic analysis. If you'd like to dig into your traffic patterns and have a better idea who's visiting your site and what they're coming to see, take a look at the Open Web Analytics (OWA) plugin for WordPress. It's easy to use, and provides a wealth of information about your site traffic.

|PC-BSD 1.3.4 review|
|PC-BSD is turning out to be an excellent alternative to other popular Desktop OSes. After testing and using PC-BSD for some time now, I can't but admire the sheer amount of work that is put into creating, developing and molding an OS for the lay person albeit with a strong slant towards FreeBSD. The fact that PC-BSD is able to accomplish all the tasks expected by an end user - be it using the Internet for communication, listening to music, watching movies or using it for recreation purposes holds it in good stead as a viable Desktop OS.
