This document will help you to set up Qmail-Scanner with ClamAV antivirus and SpamAssassin spamfilter. Qmail-Scanner is an add-on that enables a Qmail email server to scan email for certain characteristics. It is typically used for its anti-virus and anti-spam protection functions, in which case it is used in conjunction with external scanners. It also enables a site (at a server/site level) to create "Policy blocks": i.e. react to email that contains specific strings in particular headers, or particular attachment filenames or types (e.g. *.EXE attachments).

This program is an “inotify cron” system. It consists of a daemon and a table manipulator. You can use it a similar way as the regular cron. The difference is that the inotify cron handles filesystem events rather than time periods.

Alot of people seam to be having problems with proper redirection of 'sudo command' to a file. So many would rather 'sudo -s' than understand why 'sudo command > output' does not work. Wait no more, I shall tackle this problem and explain it to you!

Although you have exchanged public keys with your remote server to avoid that boring bit of entering your super long secure user password everytime you are about to login, you still need to face ssh syntax in order get someting done. Yes, it is just single line command with few words but typing that line 30 times a day can take you at least 10 minutes of problem solving time, bore you and more iportatbly it may even give you a headache. This article outlines two alternative options on how to make ssh login procedure easier and thus keeping you sane longer.

Friday, my server was purring along just fine, and then it stopped. I thought it was a power supply problem, but as I was trying to determine if the power supply was still working, I saw a small orange flash.

The next power cycle attempt also got a bit of orange, but it was not small, and the smoke and cracking sound was more than clear as to exactly what had gone wrong. I have a picture of the offending surface-mount component, but it will be hard for me to post the picture due to the other problem.

The 9th annual Southern California Linux Expo started its second day on Saturday with a keynote by Leigh Honeywell as the attendance numbers showed a significant increase over last year. Honeywell, who spoke on the topic “Hackerspaces and Free Software,” headlined a wide variety of sessions that included a standing-room only crowd for Owen De Long’s “IPv6 Basics for Linux Adminstrators” and various education-related talks in the Open Source Software in Education (OSSIE) track.

SCALE opened strong with lots of technical content, much of it about the "DevOps" movement and how you can bring its benefits to your place of business.

Review of Data Source Handbook, just coming out. A few years ago I did something utterly stupid. I listened to someone's advice. Now, I don't want to sound too cynical, but really, half or more of what people tell you is, shall we say, unconsidered. They don't stop and think that they are actually telling you something that will affect what you do next, what decision you make, how you adjust your plans, or what money you spend. So random sh#t comes flying out of their mouth and you do it and later feel stupid.

VLC, without a doubt, is the best media player around. Not only is it able to play almost any file format, it is also able to stream audio/video from the Web and transcode on the fly. VLC-share is a web implementation of VLC streaming and transcoding that allows you to stream (and transcode) your videos to your WII Media Center (WIIMC) or Android phone. Just think of airplay for Android and you get VLC-Shares. In this tutorial, we will show you how to get VLC-shares up and running in your Ubuntu machine. VLC-shares is available for Windows as well and the installation and configuration instruction is pretty easy and straightforward, so we will not touch on that.

Data compression is the process of storing data in a format that uses less space than the original representation would use. Compressing data can be very useful particularly in the field of communications as it enables devices to transmit or store data in fewer bits. Besides reducing tranmission bandwidth, compression increases the amount of information that can be stored on a hard disk drive or other storage device.

Three videos about how to insert page numbering in OpenOffice, Koffice, and Abiword. All instructions given, all in video with spoken instructions (English) I have recently published a post regarding page numbering in Open Source Office applications. This time I will repeat the same post in slightly different manner. There are video lessons showing process of document editing.

Frequently, Datamation puts together lists of top open source software. This time we've done something a little different and made a list of top open source Web sites. Of course, literally thousands of sites and forums provide news and information about open source software. To narrow things done, we focused on sites that provide a lot of links of open source applications – the top places to download open source software.

Kernel version 38 will offer a new meshing implementation, loads of new and improved LAN and Wi-Fi drivers, plus various minor changes that promise to improve the network subsystem's performance.
