This document describes how to set up TrueCrypt with GUI on Ubuntu 7.10. TrueCrypt is a free open-source encryption software for desktop usage.
This howto is a practical guide without any warranty – it doesn’t cover the theoretical backgrounds. There are many ways to set up such a system – this is the way I chose.
This tutorial is based on another howto written by DevilMan, however I didn’t like the idea of manually compiling every package or the use of a GUI to get the software installed. This howto will work on a Gutsy Server or Gutsy desktop. With that said some of this howto is a direct copy from the original.
In this tutorial I will describe how to install and configure Snort (an intrusion detection system (IDS)) from source, BASE (Basic Analysis and Security Engine), MySQL, and Apache2 on Ubuntu 7.10 (Gutsy Gibbon). Snort will assist you in monitoring your network and alert you about possible threats. Snort will output its log files to a MySQL database which BASE will use to display a graphical interface in a web browser.
This howto outlines the process by which one can set up the Subversion version control system, and have it work in tandem with Trac, the project manager for software development projects, on a server running Ubuntu (or possibly Debian). It is brought to you by Openject Consulting.
Setting up Subversion
For detailed information on this, including alternate setups, have a look at Version Control with Subversion.
This document is a step by step guide for configuring Ubuntu 7.10 as a Samba Domain Controller with an LDAP backend (OpenLDAP). The point is to configure a server that can be comparable, from a central authentication point of view, to a Windows Server 2003 Domain Controller. The end result will be a server with an LDAP directory for storing user, group, and computer accounts. A Windows XP Professional SP2 workstation will be able to join the domain once properly configured. Please note that you do not have a fully comparable Windows domain controller at this time. Do not kid yourself, this guide only gets you a server with LDAP authentication. Of course this can be expanded to include slave servers to spread out authentication over multiple networks. Please also note that it took me approximately two and a half weeks to compile this information and get it working. The same functionality can be had in Windows in less than four hours (and this includes operating system installation). In my humble opinion the open source community will need to work on this side of Linux in order for it to be a true alternative to Windows.
Joomla! is a well-known content management system, mature enough to be used by thousands of amateur and professional Web portals. Installation is a breeze and consists of six click-next steps. However, a default Joomla! installation is not necessarily a secure one, so let’s see how we can protect our portal from potential attackers.
The first rule of security when it comes to Joomla! is “update frequently,” because whenever a new version comes out, it usually comprises several user-reported bug and security fixes. If your host allows it, use PHP5 instead of PHP4, because it’s more advanced and offers better security.
Once your site is ready to be launched, make sure to set your configuration.php file to read-only — a critical step that most users neglect. Change file and directory permissions —
chmod 644 for files and
chmod 755 for folders — but be sure to keep temporary and cache directories writable, lest you get a site error.
If you use Linux on your desktop, and you also happen to have a BlackBerry handheld device, youâ€™re probably aware that Research in Motion, the company that develops the BlackBerry platform, offers nothing in the way of support for its devices on Linux â€” but the intrepid geeks in the free software world do. Thanks to to the efforts of the Barry and OpenSync projects, I just finished syncing my BlackBerry 8800 with my Evolution contacts on my Ubuntu 7.10 desktop.
If all you want to do is share data between your Linux box and the BlackBerry, no sweat. The 2GB Micro SD storage I inserted in my 8800 is available to my Linux system just like any other USB storage device. When I connect the USB cable to the BlackBerry, I simply say yes when Ubuntu asks if I want to enter Mass Storage Mode, and I can copy music and photos to the phone. I have run into a problem getting the audio for videos that were created with Kino to work correctly, but other than that, moving data back and forth between the PDA and the desktop â€œjust works.â€The Barry and OpenSync projects aim to provide a little more functionality than just moving data. According to its home page, the Barry project â€œis a GPL C++ library for interfacing with the RIM BlackBerry Handheld. It comes with a command-line tool for exploring the device and a GUI for making quick backups. This projectâ€™s goal is to create a fully functional syncing mechanism on Linux.â€ Release 0.11, which Iâ€™ve been playing with the past week, goes a long way toward meeting those goals. With it, you can explore, backup and restore, and â€” with a little help from OpenSync â€” sync databases. There is, however, some assembly required.
Creating an AS400 terminal with an Old PC and Ubuntu
This how to uses Ubuntu 7.10 Server install. I am sure that this could be done with a much smaller install base, rather than server – I might have used the Alternative CD, or maybe even some other distribution like DSL, or Puppy Linux (if you needed GUI [graphical user interface] ). But for proof of concept this worked fine. I used an Old Dell GX100 Optiplex with 256 MB of RAM (I don’t think I need any more that 128 [maybe even 64MB], but this is what was in the box when I pulled it out of the pile). It has a small form factor, and runs pretty quiet. My steps are geared toward English & US, so you may want to change those if your using something else =).
Build A HylaFax Server With AvantFax Frontend Using Debian Etch
Install Debian. I used the basic barebones install option. I did
some things that were done because of preference, and not necessary. I
have marked them approriately. I encourage contributions from anyone
who would like to add or correct something in this HowTo to contact me
so I can fix it. I have installed this setup twice following these
instructions and used Avantfax 2.3.0. Thanks to all the resources who
helped me figure this out. Especially Razametal, who submitted a
fantastic Spanish language walkthrough on ecualug.org.
Writing Snort Rules On EnGarde
There are already tons of written Snort rules, but there just might
be a time where you need to write one yourself. You can think of
writing Snort rules as writing a program. They can include variables,
keywords and functions. Why do we need to write rules? The reason is,
without rules Snort will never detect someone trying to hack your
machine. This HOWTO will give you confidence to write your own rules.
How To Masquerade On Linux (Internet Connection Sharing)
