Thus, this is the last post to the PostNuke software that performed well for quite a few years. If you're reading this, that means your DNS has not propagated to point to the new site. Don't worry about that -- it'll happen soon. Wed, 12 Jul 2006 21:15:17 +0200 http://oldsite.debianhelp.org/Article3707.html This HowTo is about creating a user-session-safe directory which offers security on- and offline. This is done with PAM, a module named pam_script and EncFS ("Encrypted Filesystem"). This safe directory is used to store credentials and other sensitive information during a session. When a usersession is ended, in the worst case an encrypted directory remains on the harddrive. In the best case everything is removed. This construction is only meant to store information during a session, not for documents or any other valid information.

It can be used for general reporting, for sending notifications when problems arise, or for automatic maintenance and repairs - by executing scripts when errors or particular conditions arise.The BixData system is made of three separate parts. The BixAgent runs on any machine you want to monitor. The BixServer is used to monitor machines remotely and to keep track of many different machines. The BixDesktop is a graphical interface that is used to setup and interact with the rest of the system. http://www.howtoforge.com/server_monitoring_bixdata Mon, 10 Jul 2006 14:30:06 +0200 http://oldsite.debianhelp.org/Article3705.html Cream is a userfriendly plugin which makes it easier to use Vim by normal users. What is unique about this plugin is that it retains all the power of Vim and makes more specialised functions of Vim easily accesible as a menu entry. Also the key shortcuts are remapped to mirror those found in windows editors. Read more about this interesting plugin. Fri, 07 Jul 2006 15:22:18 +0200 http://oldsite.debianhelp.org/Article3704.html Sometime soon the software that runs the debianHELP web site will be changed. This will be, in effect, creating a new web site. It's often said that change is a love/hate thing, with both good and bad points. The site has only had one serious change in the 6 years it's been online: Years ago I migrated the site to a more forum-based focus and that's worked out pretty well. But soon there will be some equally serious conceptual changes aimed at providing users an easier and more flexible way of solving problems, getting questions answered and in finding information. With that change will come some new features and tools. Needless to say I'm psyched about the change and what we can do with it. The exact timing of the change is still to be determined, but it's close. If you're only an occasional visitor don't be surprised if you connect to the site one day and it looks quite different and you have to create a new account. Wed, 05 Jul 2006 22:35:01 +0200 http://oldsite.debianhelp.org/Article3703.html The recently released Google Web Toolkit (GWT) is a comprehensive set of APIs and tools that lets you create dynamic Web applications almost entirely in Java code. However, GWT is something of an all-or-nothing approach, targeted at a relatively small niche in Web application development market. This article shows you what GWT can do (free reg. req'd) and will help you decide if its the best tool to use for your web development. Wed, 05 Jul 2006 06:27:21 +0200 http://oldsite.debianhelp.org/Article3702.html Several browsers recently completed or announced built-in Scalable Vector Graphics (SVG) support. This tutorial focuses on SVG for Web development (free reg. req'd), offering step-by-step instruction for Web developers and designers to learn how to use SVG and vector graphics in Web sites.

There now are forums for the Apple Macintosh and Sun SPARC architectures. Sat, 01 Jul 2006 22:41:56 +0200 http://oldsite.debianhelp.org/Article3700.html This tutorial contains step-by-step instructions for installing Xen 3.0 from precompiled binaries in Ubuntu Dapper Drake.Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one. http://www.howtoforge.com/xen_3.0_ubuntu_dapper_drake Thu, 29 Jun 2006 15:33:39 +0200 http://oldsite.debianhelp.org/Article3699.html Monitoring your file systems and ensuring they don't fill up is a vital process in the day-to-day management of your UNIX systems. This article looks at methods for keeping an eye on disk space (free reg. req'd), discovering which files, users, or applications are using up the most space, and how to make use of quotas and other solutions to find the information you need. Wed, 28 Jun 2006 06:32:53 +0200 http://oldsite.debianhelp.org/Article3698.html Given the constant stream of news about the many ways the US gov't is spying on people, I've been thinking more about Internet privacy. So I decided to check out anonymous proxy services. While nice, most cost money and that didn't thrill me. Then I ran across "The Onion Router" or Tor. This was exactly what I was looking for -- and more. Background Call me paranoid if you'd like, but you should be worried about Internet privacy. People are watching you and what you are doing. Not a big deal you think? If that's the way you feel, you're probably not aware of all the ways data collected on the Internet is used. Mon, 26 Jun 2006 13:15:53 +0200 http://oldsite.debianhelp.org/Article3697.html In in Part 1 of this series (free reg. req'd), you'll learn how to use the LDAP Tools for Eclipse to configure Geronimo's built-in Apache Directory LDAP server. In Part 2 you'll query the LDAP server and update the Web page using Ajax. You'll also get familiar with some of the techniques to build LDAP-centric applications using the toolsets available in the Java platform and Ajax. Sun, 25 Jun 2006 05:30:11 +0200 http://oldsite.debianhelp.org/Article3696.html The Nexenta project, which builds a distribution combining the OpenSolaris kernel with applications from Ubuntu, has announced a new alpha release of NexentaOS: "This release provides a fully integrated Ubuntu Dapper Drake userland, OpenSolaris core (build #40), and contains overall 11800 packages. In addition, Alpha 5 contains: Sun's Java SE 5.0 Java Development Kit (via NexentaOS APT); live upgrade; and OpenOffice.org 2.0, natively compiled on Nexenta OS." Usually closed source binaries drivers re-distributed by hardware manufactures. This is a basic way for HW companies to supply their drivers. Unfortunetly, Linux kernel does not support it. Linux kernel interfaces are *unstable* which creates a lot of headaches for an end users especially on a Desktop. NexentaOS has a chance to succeed on a Desktop - it supports binary-only drivers the way Windows XP does via utilizing Kernel Device Driver API interfaces, which are stable and preserved over time. Fri, 23 Jun 2006 15:36:07 +0200 http://oldsite.debianhelp.org/Article3695.html This tutorial shows how you can run your own name servers for domains that you register with GoDaddy. Of course, this works with every other registrar as well, although the procedure might differ a little bit.To do this, you need two servers with two different public IP addresses and with ISPConfig installed, and of course a GoDaddy account. http://www.howtoforge.com/ispconfig_dns_godaddy Thu, 22 Jun 2006 04:14:53 +0200 http://oldsite.debianhelp.org/Article3694.html The typical UNIX administrator has a key range of utilities, and tricks of the trade he or she uses regularly to aid in the process of keeping their system running smoothly. A majority of the tricks come through years of experience and a desire to ease the system administrator's life. This Study provides examples of how to identify and diagnose the cause of a slow running UNIX system (free reg. req'd) to get your machine back to running properly and quickly. Tue, 20 Jun 2006 14:33:11 +0200 http://oldsite.debianhelp.org/Article3693.html This tutorial shows how to install and use suPHP with PHP4 and PHP5. suPHP is a tool for executing PHP scripts with the permissions of their owners instead of the Apache user. With the help of suPHP you can also have PHP4 and PHP5 installed at the same time which I will describe at the end of this article. http://www.howtoforge.com/apache2_suphp_php4_php5 Mon, 19 Jun 2006 13:46:19 +0200 http://oldsite.debianhelp.org/Article3692.html After nearly 20 years, Internet Protocol v4 is finally updated. The next-generation Internet protocol, version 6 (IPv6), will soon be the new world order of the Internet (free reg. req'd). As it grows in popularity, a cluster of new IPv6 features and opportunities will change the way we use the internet. This article shares the concepts of the next-generation Internet protocol and how we can benefit from it. Sat, 17 Jun 2006 14:52:37 +0200 http://oldsite.debianhelp.org/Article3691.html In this tutorial I will describe how to install and configure mod_deflate on an Apache2 web server. mod_deflate allows Apache2 to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier. http://www.howtoforge.com/apache2_mod_deflate Thu, 15 Jun 2006 13:55:50 +0200 http://oldsite.debianhelp.org/Article3690.html Bacula is a set of computer programs that permits you (or the system administrator) to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula can also run entirely upon a single computer, and can backup to various types of media, including tape and disk. In technical terms, it is a network Client/Server based backup program. Bacula is relatively easy to use and efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files. Due to its modular design, Bacula is scalable from small single computer systems to systems consisting of hundreds of computers located over a large network. Read full article here.

Wed, 14 Jun 2006 13:35:24 +0200 http://oldsite.debianhelp.org/Article3689.html This is a detailed description about how to set up a Ubuntu 6.06 LTS server that offers all services needed by ISPs and hosters (Apache web server, Postfix mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.). This guide comes with lots of screenshots and is therefore easy to follow even for Linux newbies. http://www.howtoforge.com/perfect_setup_ubuntu_6.06 Mon, 12 Jun 2006 11:57:22 +0200 http://oldsite.debianhelp.org/Article3688.html Learn about several basic database concepts, including schemas, tables, and column data types, and get a simple introduction to Structured Query Language (SQL). This article -- focusing on the database developer role (free reg. req'd) -- presents the basic data types you can use to store data in an Apache Derby database. Sun, 11 Jun 2006 15:26:34 +0200 http://oldsite.debianhelp.org/Article3687.html This article shows how to install and configure mod_cband on an Apache2 web server. mod_cband is an Apache2 module which provides bandwidth quota and throttling. It solves the problem of limiting users' and virtualhosts' bandwidth usage. The current versions can set virtualhosts' and users' bandwidth quotas, maximal download speed, requests-per-second speed and the maximal number of simultaneous IP connections. http://www.howtoforge.com/mod_cband_apache2_bandwidth_quota_throttling Fri, 09 Jun 2006 13:15:00 +0200 http://oldsite.debianhelp.org/Article3686.html The cpio command is one of the most commonly used Linux back up tools. The cpio command has two unusual features. Unlike tar , in which the files to back up are typed in as part of the command, cpio reads the files to work with from the standard input (in other words, the screen). This feature means that cpio must be used as part of a multiple command or with a redirection pipe. cpio must always be used with one of three flags. Flags are options that set the mode in which the command runs. Only one flag can be used at a time, and it must come before any other options. In addition, the choice of flags limits the options that can be used. Each flag also has a gnu option that can used in its place. The gnu option gives a convenient name for each flag: extract, create, and pass- through.

According to our Release Managers' schedule, next week, we should have no more than 300 release-critical bugs. As of today, we are around 340[1]. That's way too far from our goal. We are consequently setting up a real life Bug Squashing Party next week-end near Paris as part of the BSP Marathon[2]. This BSP will be kindly hosted by "VIA - Centrale Réseaux", the student-managed network association of the École Centrale Paris engineering school at Chatenay-Malabry. Practical details (accomodation, food, location...) are all noted on the wiki page[3] (sorry for the short notice, though). It will be held from Friday evening to Sunday evening: June 9 - 11. The main objective will be to make us respect the release schedule and go under the 300 bugs bar (and even below, if possible). Anyone wanting to remotely help is of course welcome, and will find us on the #debian-bugs channel on irc.debian.org (OFTC). There should be plenty of bugs for all levels of complexity, programming language or legal skills and time requirements. So if you never attended to a BSP before and want to help, *now* is the right time to start. Tue, 06 Jun 2006 14:28:42 +0200 http://oldsite.debianhelp.org/Article3683.html Spamcop is pretty much dependant on user input. If no one submits and verifies spam, then they will have no blacklist. However that whole submission and verification process is a bit annoying. Why should I bother to actually submit spam to Spamcop and have it verified? If I just delete it, that will take less time... This tutorial shows how to automate this submission and verfication process. All I do is just putting the spam into certain folders and our good old friend cron does the rest. http://www.howtoforge.com/automate_spamcop_submissions Mon, 05 Jun 2006 11:32:07 +0200
