Tutorial quote: eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux.It provides advanced key management and policy features. eCryptfs stores cryptographic metadata in the header of each file written, so that encrypted files can be copied between hosts; the file will be decryptable with the proper key, and there is no need to keep track of any additional information aside from what is already in the encrypted file itself. Think of eCryptfs as a sort of “gnupgfs”.eCryptfs is a native Linux filesystem. The kernel module component of eCryptfs is part of the Linux kernel since 2.6.19.

| Tutorial quote: In the previous two articles in this series, we examined some of the whys and whats of building Linux clusters. This article concludes our series by concentrating on the hows of cluster building. We've seen that a clustered approach to certain computing solutions can save lots of money in hardware and support costs. Now our job is to produce a method of building clusters that's repeatable and predictable—we don't want to give back our hard-won savings in project cost overruns. |

| 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 want to monitor and manage your Internet bandwidth, perhaps to make sure your ISP is not overbilling you, try vnStat, an open source, Linux-based application that gives you a clear picture of your bandwidth usage. This utility got the command-line options and also got the UI part which give the output in form of a graph and is simple to install and easy to use. |

| Tutorial quote: With the release of Microsoft's new Windows operating system (Vista), more and more people are looking for alternatives to Windows for various reasons. This tutorial is the first of a series of articles where I will show people who are willing to switch to Linux how they can set up a Linux desktop (Fedora Core 6 in this article) that fully replaces their Windows desktop, i.e. that has all 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, and the best thing is: all software comes free of charge. |

| Tutorial quote: This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch). I was asked to design a secure, scalable, portable solution for a small company. While the guide references many servers, the company only had 4 physical machines, Xen was used to virtualize the entire solution. That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision. |

| Tutorial quote: Setting up a DHCP Server for your Home or Company Network is pretty simple with NetBSD. You don't need to install any Software, because everything you need, is part of the base system. |

| Tutorial quote: I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group. |

| Tutorial quote: Last week, we looked at how to set up SpamAssassin with Postfix, as part of a lean, mean, spam-killing gateway machine. This week we'll add an anti-virus scanner to our bubbling brew. |
