Unix+clones Using Impress-ive Charts In OpenOffice.org
Post date: April 14, 2005, 08:04 Category: Software Views: 716 Comments: 0
Tutorial quote: Anybody that does presentations will someday need to use a chart. A manager needs charts to show production numbers and profits. A scientist or trainer needs charts to show facts, figures and results. A sales seminar leader needs charts to explain sales figures. So, what's involved in getting these nifty things into your OpenOffice.org-based slide show?

The process of integrating charts into your Impress slide show is fairly straightforward, although it does involve a few steps and two different components of OpenOffice.org.

Tutorial quote: Making the switch from Microsoft Office to OpenOffice can save you a lot of money on licensing fees, and it isn't difficult--most people get used to the changes quickly. But if you've been using MS Office for the best part of a decade and learned a few of its tricks along the way, you may find yourself baffled about how to do certain tasks in OpenOffice. Here are a few tips on using Writer, Calc and Impress.
Unix+clones KMail In Depth
Post date: April 13, 2005, 15:04 Category: Software Views: 802 Comments: 0
Tutorial quote: KMail has long been my Linux email client of choice for a number of reasons: nice clean interface, easily customizable and configurable, stable, and more features than you can shake a stick at. Today we'll dig into migrating from other email clients, encrypting messages and key signing, and configuring multiple accounts and identities.
Unix+clones The 'no-configuration, only-active-when-needed' SSH VPN
Post date: April 12, 2005, 22:04 Category: Network Views: 872 Comments: 0
Tutorial quote: So, we started thinking about how we might set up a VPN between the application server and our internal software mirror. The only requirement is that the VPN be initiated from the "inside-out" and that the connection is only active for as long as we need to use. In other words, it would only be active during an administration session. Ideally, it wouldn't be a lot of work to setup and tear down either.

SSH to the rescue...

Fortunately, SSH client and server come with support for this out of the box, requiring no additional software to be installed, and no configuration changes. On the server side, sshd, the setting "AllowTcpForwarding" defaults to "yes" unless your sshd_config file explicitly disables it. On the client side, all you have to do is request the forwarding.
Unix+clones UNIX Shell Programming QuickStart

Tutorial quote: If you read, write, or maintain programs, the following samples will give you a quick overview of the construction and style of a shell script and introduce you to some of the constructs and syntax found in these programs.
Unix+clones Writing Shell Scripts
Post date: April 12, 2005, 21:04 Category: Programming Views: 1426 Comments: 0
Tutorial quote: With the thousands of commands available for the command line user, how can you remember them all? The answer is, you don't. The real power of the computer is its ability to do the work for you. To get it to do that, we use the power of the shell to automate things. We write scripts.
Unix+clones Graphical Scripting with Kommander
Post date: April 12, 2005, 21:04 Category: Programming Views: 944 Comments: 0
Tutorial quote: Kommander is a simplified and modified version of Qt Designer which lets you add scripting abilities to the dialogues it makes. It saves the result as a designer UI file which can be run with Kommander Executer. It is the easiest way to make simple programmes, I like to think of it as graphical shell scripting.

Konstuct is a program to download and install KDE from sources. This tutorial takes us through using Kommander to make a graphical program to configure and run Konstruct.
Unix+clones Using Afick To Aid In Intrusion Detection
Post date: April 12, 2005, 20:04 Category: Security Views: 862 Comments: 0
Tutorial quote: Afick is a fast and portable utility which acts as an aid in intrusion detection as well as helping to monitor the general integrity of your system. Afick was written by Eric Gerbier and is distributed under the GNU General Public License. It is available for a number of platforms in both binary and source formats.
Unix+clones Remote backup using ssh, tar and cron
Post date: April 12, 2005, 20:04 Category: Miscellaneous Views: 938 Comments: 0
Tutorial quote: Are you looking for a solution to backup your data to a remote location? While a solid backup solution such as Arkeia or TSM from IBM are nice from an enterprise point of view, simpler solutions are available from a home user's perspective. I will walk you through on you how you can backup your data to a remote server, using the default tools available on all linux systems. In a nutshell, we will use ssh capabilities to allow a cron job to transfer a tarball from you local machine to a remote machine.

For the purpose of this tutorial, the local machine will be called “localmachine” (running slackware) and the remote server will be called “remoteserver” (slackware as well). The user will be joe (me). You will have to substitute those 3 with your own machines names and user.
Unix+clones Apache Maintenance Basics
Post date: April 12, 2005, 20:04 Category: Software Views: 905 Comments: 0
Tutorial quote: You've downloaded and configured your Apache server and are ready to move on to the next project. Can it really be left to fend for itself in a darkened room?

Yes. To some degree, anyway. With the exception of configuration testing, once Apache is up, you likely need never think about how the Web server is running.

On the other hand, completely ignoring your Apache installation would be foolhardy. Doing some regular checks and maintenance on your Apache installation helps identify any issues — usually before they even become issues — and helps you stay up date with the latest security and performance patches. This article covers some of the major steps and maintenance tasks that should be regularly undertaken while the Apache system is running.
