How I backup my WordPress sites

No Comments, Backup, by suvi.

When I first started using WordPress back in March, 2006, one of the first bad habits I go into was not backing up my sites. Okay, I just had one small website back then, SaigonNezumi.com, I still needed to back up my site. I did have backups of images and the WordPress install itself, but not of my database. I think I kept running site for nearly two years until one day, I accidentally deleted my database where SaigonNezumi.com resided. Whoops, luckily a $30 US fee to AnHosting, my webhost at the time, and I was able to recover my database.

Four Hidden Tools in Scribus

No Comments, Office, by suvi.

Scribus is a powerful tool, but its menus are poorly laid-out. While you can usually find the features you most frequently use without any trouble, others may be hidden almost anywhere. From the Extras, Script, and Windows menus to the Document Setup dialog, useful features can be positioned almost anywhere, with only the most token regard for logic.

The tools described here are ones that took some time for me to discover in Scribus. None are worth more than a few hundred words of description, but I mention them here because all of them can be useful to know.

PartedMagic: A Swiss Army Knife for Hard Drive Resuscitation

No Comments, Tricks, by suvi.

I started out looking for a handy disk partitioning tool to repair a colleague’s ailing computer. I ended up finding a toolbox full of very handy repair and system maintenance apps. As a bonus, I got all of this packed into a nifty specialized Linux distro called “PartedMagic” that boots into RAM from a CD or USB drive. PartedMagic is compact and lightweight. Having a live distribution built around GParted is a failsafe way to use Linux to manage your computer’s hard disk. Normally, any OS will partition the hard drive as part of the installation process.

Help for osCommerce administrators

No Comments, Security, by suvi.

osCommerce systems are currently being targeted by a mass hacking attack – online shop administrators need to act immediately. This article aims to help administrators to help themselves.

Most of the alerts regarding the mass infection of osCommerce shops merely recommend updating to the latest version, 2.3.1. Unfortunately, performing this upgrade is anything but trivial. In many cases it essentially boils down to setting up the whole shop again from scratch. Even the database format has changed, with the result that a dump of an old version can’t be used without substantial spadework.

All of which costs time, but with the danger acute, a rapid reaction is required. This short guide has been put together to help users to check whether their osCommerce system is vulnerable, to check whether they have been infected and to apply a workaround to provide at least temporary security.

No Comments, OpenOffice.org, by suvi.

Do you want to see your name on the front page of a book? It’s easier than you might think. First, write the book. Next, follow these simple steps to prepare an ebook using the free OpenOffice.org desktop publishing application.

Publishing ebooks today can be a DIY business. If you write for a specific audience, you can create a successful book without the help of big companies, and get your work into the hands of readers who can download ebooks from popular sites such as Amazon CreateSpace, Lulu, or Lightning Source.

Let’s assume you’ve already written the book you want to publish. Your work might be in plain text format or written using a word processing application. No matter where it starts out, import it into OOo Writer and use that program’s rich set of tools to create a file for publication.

Sniffing Passwords Over a Wifi Connection [Linux]

No Comments, Security, by suvi.

Now here’s where some fun stuff starts!
I hope many of you have followed my installing Backtrack 5 guide and read up on what ARP is as well as basic Linux commands so you can follow along easily; if not, go read those now!

What you’ll need for this tutorial:

Backtrack 5 or Linux on your computer.
SSLStrip installed (to bypass HTTPS connections)
Ettercap installed.
Arpspoof installed (comes on Backtrack 5 by default).

If you don’t have any of these, follow the links and set up your system before continuing.

Okay, so what we’re doing today is using a few programs to sniff passwords over a network and redirect secure HTTPS connections to non-secure HTTP connections to help us get even more passwords.
I’ve successfully gotten passwords and user names from Gmail, Facebook, Ureddit, Reddit, and Youtube; but all sites should work.

Five Common Weaknesses in a Linux Server that are Worth Covering

No Comments, Security, Server, by suvi.

There seems to be a belief these days that complying with the PCI standard is bound to be expensive and difficult to put in place. Actually if you have a Linux system, this doesn’t have to be the case at all. However, while a Linux system is generally thought to be better for security, nevertheless, there are weaknesses to Linux that could be exploited by a potential hacker, and knowing these weaknesses and knowing how to deal with these weaknesses can be crucial to the server administrator who wants to ensure that his systems and networks are PCI complaint.

Actually, with Linux security, knowing in advance what you are going to need to secure and making the right alterations in the right place can go a long way towards perfecting your security. Anyone who’s worked with PCI-DSS knows that truly enhancing the effectiveness of this system lies in a complete understanding of the risk factors. Generally speaking, I would say that limiting risk factors primarily lies in the realm of limiting access. Now when I say limiting access I’m not just talking about password security, but about even small lapses in security that could be used by a potential hacker.

5 Basic SSH Security Tips

No Comments, Security, by suvi.

SSH (Secure Shell) is designed with security in mind. In the old days, people often used Telnet to connect to their servers, but that was back when servers were down the hall, not over the vast expanse of the uncharted Internet. SSH adds a layer of encryption to the transmission, ensuring that you can connect to your dedicated server or virtual private server (VPS) without the risk of having your password intercepted.

Although SSH is more secure than most Internet protocols by default, you can still do more to make it even more secure. The following are five tips for SSH security bliss.

How To Install OpenERP 6 On Ubuntu 10.04 LTS Server

No Comments, Office, Server, Software, by suvi.

Recently at, we’ve been setting up several new instances of OpenERP for customers. Our server operating system of choice is Ubuntu 10.04 LTS. Installing OpenERP isn’t really that hard, but having seen several other “How Tos” online describing various methods where none seemed to do the whole thing in what I consider to be “the right way”, I thought I’d explain how we do it. There are a few forum posts that I’ve come across where the advice is just plain wrong too, so do be careful.

As we tend to host OpenERP on servers that are connected to the big wide Internet, our objective is to end up with a system that is:
