Building a Linux virtual server

Post date: June 9, 2005, 14:06 Category: Software Views: 3539 Comments
Tutorial quote: With the explosive growth of the Internet, the workload on servers providing Web, email, and media services has increased greatly. More and more sites are being challenged to keep up with the growing demands and are employing several techniques to avoid overloading their servers. Building a scalable server on a cluster of computers is one of the solutions that is being effectively put to use. With such a cluster, the increasing requests can be easily managed by simply adding one or more new servers to the existing cluster as required. In this article we will look at setting up one such scalable, network load-balancing server cluster using a virtual server via the Linux Virtual Server Project.

Virtualization With VirtualBox 3.1.x On A Headless Fedora 12 Server

Tutorial quote: This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x on a headless Fedora 12 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.

How To Automate Spamcop Submissions

Post date: May 26, 2006, 07:05 Category: Network Views: 3660 Comments
Tutorial quote: Spamcop is a service which provides RBLs for mailservers in order to reject incoming mail from spammers.

Their philosophy is to process possible spam complaints from users. When they receive a certain amount of complaints during a time-period then they will blacklist the offender. This system is dependant on spam reporting from users. However, their submission process is not very user-friendly.

As I have said above, Spamcop is pretty much dependant on the user input. If no one submits and verifies spam, then they will have no blacklist. However that whole submission and verification process is a bit annoying. Why should I bother to actually submit spam to spamcop and have it verified? If I just delete it, that will take less time...

The human being isn't really made to do repeating things. This gets quickly boring and hence my idea to automate this submission and verfication process.
In this howto I will show you how I achieved that. All I do is just putting the spam into certain folders and our good old friend cron does the rest.

Tutorial quote: This tutorial shows how to set up Zimbra Collaboration Suite - Open Source Edition on CentOS. This tutorial covers installation of CentOS, dependencies for ZCS and setup of Split DNS when working behind a firewall. This tutorial is based on the way I set this server up and is only a suggestion. It carries no guarantees and it is highly suggested that you do this on a test server first to verify functionality. If you don't have a test server available you should download VMWare Server 1.0 and perform this tutorial on a test virtual server.
