| Tutorial quote: The Web site hosting business has become more competitive in recent years. If you can find a better hosting deal, you may be able to save money by switching hosting providers. But what's the best way to move your Web site? What if you have a virtual private server (VPS) hosting several domains? What about PHP and your SQL data? The thought of moving may be daunting, but moving servers is not difficult if you plan properly. Here's how. |

| Tutorial quote: The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails. |

| Tutorial quote: In this tutorial I will describe how to install and configure MyDNS and MyDNSConfig 3 on Fedora 10. MyDNS is a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. MyDNSConfig is an easy to use web-based interface to MyDNS. MyDNSConfig can create all types of DNS records that are available in MyDNS and adds features like user management and access privileges. |

| Tutorial quote: Postfix is fast out of the box, but like other packages, you can usually tune it to work even faster. Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems. |

| Tutorial quote: Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT (vmx) or AMD-V (svm). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream. |

| Tutorial quote: The release of Red Hat Enterprise Linux 4 debuts the first commercially supported inclusion of Security-Enhanced Linux (SELinux). An installation of Red Hat's latest enterprise operating system has SELinux installed and enabled by default. In the past SELinux has been criticized for a lack of commercial support, many big sites were unable to use it due to the lack of support (Fedora Core 3 doesn't have the support that they require). Now in Red Hat Enterprise Linux 4, SELinux is a supported part of the OS, and such objections to the use of SELinux have gone away. SELinux is now widely regarded as being suitable for the largest sites. |

Tutorial quote: If you are using LDAP or NIS to manage users you might discover users having problems because they don't have a home directory on each machine they can connect to. Thankfully there is a simple solution for creating home directories upon demand for users.
The Pluggable Authentication Modules library, or PAM, is a collection of shared libraries which control how users login to systems. There are a number of modules installed which can be used to restrict user access to systems in different ways. There are also several utility modules which can be used to customise login behaviour. |
