Creating (and Maintaining) Perl Modules

Post date: May 1, 2005, 17:05 Category: Programming Views: 3023 Comments
Tutorial quote: The goal of this web page is to help you write easily maintainable and re-usable code. In Perl, re-usability is implemented through modules, which are similar to libraries in other languages.

This page will guide you through creating your module and documenting it, as well as giving you some tips on how to make your code as maintainable and re-usable as possible.

Keep Your Processes Running Despite A Dropped Connection

Post date: February 17, 2009, 08:02 Category: Software Views: 2733 Comments
Tutorial quote: I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labor. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task.

How To Compile rTorrent From SVN In Ubuntu Feisty Fawn / Gutsy

Post date: September 17, 2007, 21:09 Category: Installing Views: 2787 Comments
Tutorial quote: Torrent is a great way to transfer large files very quickly. However most torrent clients are gui based and have quite some impact on system resources (e.g. Azureus). rTorrent is a lightweight client running from the terminal. Being able to run it in a screen session (also upon boot) makes it ideal to also control it from a remote location.

Stack Smashing Protection for Debian

Post date: June 23, 2006, 22:06 Category: Security Views: 2875 Comments
Tutorial quote: Since we last covered the use of Stack Smashing Protection (SSP) the default compiler for Debian Sid has been upgraded to include it, with no need for custom patching. Read on for a brief demonstration of how it can be used to prevent attacks.

The default C compiler for Sid, which will be used in Etch too, is GCC v4.1. This releasecontains the SSP patch which previously needed to be applied manually (we demonstrated applying this patch for GCC v3.4 a long time ago).

Since the SSP patch is included in the compiler by default it is suddenly a lot easier to start working with it.

Install and Configure Auth Shadow on Debian/Ubuntu

Post date: February 23, 2007, 18:02 Category: Miscellaneous Views: 3678 Comments
Tutorial quote: Auth Shadow or mod-auth-shadow is a module for apache (and apache2, sort of) that enables authentication against /etc/shadow. The benefits being that any system user with a password can be authenticated for web_dav, subversion or simply an https server. The only other way to do this is with PAM. That method is dangerous because the apache user (www-data in my case) must be able to read /etc/shadow. Obviously, not a good idea. Auth Shadow accomplishes this safely by using a intermediate program called validate. This works because validate can be owned by root but executable by everyone. In the event that your server is compromised through apache, your password file will not be readable.

Cleaning up a Debian GNU/Linux system

Post date: November 25, 2006, 08:11 Category: System Views: 3420 Comments
Tutorial quote: You arrive at a Debian GNU/Linux server which has some history of neglection. Let's suppose someone else neglected it but if your new-year resolution is to stop neglecting your beloved server, this applies as well.

One form of neglection is to install, install, install and never un-install any package. The common utility to perform installation and un-installation of packages is apt-get which adds to the problem because it doesn't have automatic removal of non-needed dependences.

That means that when phpMyAdmin was installed it also installed Apache, PHP and ton of other packages. phpMyAdmin was removed when it was no longer needed but Apache, PHP and the ton of packages remain there.

Aptitude to the rescue.

Apache Maintenance Basics

Post date: April 13, 2005, 01:04 Category: Software Views: 2837 Comments
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.

Tutorial quote: Have some old boxes around? You can save money buy following the tutorial below and roll your own thin client using openSuSE 10.2 and a custom xdm script that loads a python script containing two button, one for shutting down the computer and one for logging into an RDP session.

Creating An NFS-Like Standalone Storage Server With GlusterFS On Debian Lenny

Post date: June 4, 2009, 11:06 Category: Installing Views: 3476 Comments
Tutorial quote: This tutorial shows how to set up a standalone storage server on Debian Lenny. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 servers with SATA-II RAID and Infiniband HBA.

Tutorial quote: Most of you have probably heard of Ruby on Rails and may be wondering what exactly it does and how you can try it for yourself. Put simply, Rails is a web application framework that uses the model-view-controller software design pattern to allow for rapid development of web applications. This article will cover how to install Rails on Debian and how to configure it to work with Apache and a relational database of your choice.
