It offers the ease-of-use of Dropbox and box.net without vendor lock in. ownCloud users can run its file sync and share services on their own hardware. nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.http://www.howtoforge.com/running-owncloud3-on-nginx-lemp-on-debian-squeeze-ubuntu-11.10 05.02.12 12:15 http://www.unixro.net/index.php?_m=news&_a=view&id=1793 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, ClamAV and SquirrelMail.http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-centos-6.2-x86_64 02.02.12 11:22 http://www.unixro.net/index.php?_m=news&_a=view&id=1792 This tutorial provides step-by-step instructions on how to install Xen (version 4.1.2) on a CentOS 6.2 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other, but still use the same hardware.http://www.howtoforge.com/virtualization-with-xen-on-centos-6.2-x86_64-paravirtualization-and-hardware-virtualization 31.01.12 11:51 http://www.unixro.net/index.php?_m=news&_a=view&id=1791 This article is about how to create a DVD image of your machine with the exact same software included on the disk. This can be done using a software called Relinux. Relinux is a fork of the recently discontinued Remastersys.http://www.howtoforge.com/creating-your-own-distributable-ubuntu-dvd-relinux 29.01.12 11:55 http://www.unixro.net/index.php?_m=news&_a=view&id=1790 Dualbooting means having installed two operating systems on one hard disk and being able to boot from any of them. This tutorial will explain how to install Linux Mint 12 alongside Windows 7 - the procedure however should be the same for all Ubuntu based distributions and only slightly different for every other.http://www.howtoforge.com/dualbooting-windows-7-and-linux-mint-12 26.01.12 14:01 http://www.unixro.net/index.php?_m=news&_a=view&id=1789 This guide explains how you can run virtual machines with VirtualBox 4.1 on a headless Ubuntu 11.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.http://www.howtoforge.com/vboxheadless-running-virtual-machines-with-virtualbox-4.1-on-a-headless-ubuntu-11.10-server 24.01.12 11:00 http://www.unixro.net/index.php?_m=news&_a=view&id=1788 This tutorial shows how to prepare a CentOS 6.2 x86_64 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: nginx web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache; this tutorial covers the setup of a server that uses nginx, not Apache.http://www.howtoforge.com/perfect-server-centos-6.2-x86_64-with-nginx-ispconfig-3 22.01.12 11:41 http://www.unixro.net/index.php?_m=news&_a=view&id=1787 This tutorial shows how you can use a free Class1 SSL Certificate from StartSSL to secure your ISPConfig 3 installation and get rid of self-signed certificate warnings. The guide covers using the SSL certificate for the ISPConfig web interface (both Apache2 and nginx), Postfix (for TLS connections), Courier and Dovecot (for POP3s and IMAPs), and PureFTPd (for TLS/FTPES connections). If you've installed monit and use HTTPS for its web interface, I will show you how to use the StartSSL certificate for it as well. This guide assumes you use Debian or Ubuntu; the principle is the same for other distributions supported by ISPConfig 3, but paths might differ.http://www.howtoforge.com/securing-your-ispconfig-3-installation-with-a-free-class1-ssl-certificate-from-startssl 19.01.12 12:03 http://www.unixro.net/index.php?_m=news&_a=view&id=1786 LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a Fedora 16 server with PHP5 support (mod_php) and MySQL support.http://www.howtoforge.com/installing-apache2-with-php5-and-mysql-support-on-fedora-16-lamp 17.01.12 12:23 http://www.unixro.net/index.php?_m=news&_a=view&id=1785 This tutorial shows how to prepare a CentOS 6.2 x86_64 server for the installation of ISPConfig 3, and how to install ISPConfig 3.
