Gentoo Monitoring all filesystem modifications
Post date: April 12, 2005, 03:04 Category: Security Views: 58
Tutorial quote: After loading this kernel module you can monitor all file system alterations by simply typing: cat /dev/fsysmon

It's original purpose was to feed a daemon with data but nevertheless I found it to be even more useful as a standalone project.
Debian Creating .deb-Packages With Checkinstall
Post date: April 12, 2005, 13:04 Category: Miscellaneous Views: 48
Tutorial quote: Checkinstall is a nice tool to create simple .deb-packages that you can use in your local network (e.g. if you have to install the same piece of software on multiple computers running Debian). It lets you compile and install software from the sources like before, but with the difference that you end up with a simple Debian package which also means that you can easily uninstall the software you just compiled by running dpkg -r!

I will demonstrate the use of checkinstall by compiling and installing the anti-virus software ClamAV on a Debian system.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.
Unix+clones Unattended, Encrypted, Incremental Network Backups
Post date: August 12, 2005, 14:08 Category: Network Views: 81
Tutorial quote: This article describes a complete system for creating a centralised backup system, complete with strong encryption. Incremental backups are used to minimize the bandwidth, and time, used.
Unix+clones X Window Manager Benchmarks (E17 on Top)
Post date: June 9, 2005, 10:06 Category: Benchmarks Views: 130
Tutorial quote: I've been focusing on some stability issues of late in E17, but more importantly - speed. I've been doing a little profiling and shaving off cycles where I can find readily optimizable code. I have E17 starting in 0.52 seconds (from execute to usable desktop). Considering that involves loading and rendering and scaling a complex multi-leayered desktop background, loading multiple useful modules (pager, ibar, start, dropshadow, cpufreq handler, clock, etc.), then that's not too bad.

Now I'm a numbers man. I like numbers. I don't like vague "it's faster than X" or "that's slower than this" statements without numbers to back it up. I also like to play fair. Also given there are no "performance suites" i know of that measure window manager performance, I wrote a quick and dirty one.
Unix+clones The lost art of named pipes
Post date: April 15, 2005, 17:04 Category: System Views: 58
Tutorial quote: A "named pipe" -- also known as a FIFO (First In, First Out) or just fifo -- is an inter-process communication mechanism that makes use of the filesystem to allow two processes to communicate with each other. In particular, it allows one of these to open one end of the pipe as a reader, and the other to open it as a writer. Let's take a look at the FIFO and how you can use it.
Linux Linux Filesystems and Partitioning: A Primer
Post date: June 24, 2005, 10:06 Category: System Views: 87
Tutorial quote: We recently to shed some light on Linux, particularly for users unfamiliar with the system. The article received quite a response from around the world and so we will be doing some follow-up articles to teach all those interested, the ins and outs of Linux. In this article, we will be discussing what partitioning is, how to choose a filesystem, how to have Windows and Linux installed on your hard drive at the same time, and more.
Linux How to set up a mail server on a GNU / Linux system
Post date: February 7, 2006, 02:02 Category: Network Views: 52
Tutorial quote: Easy to follow howto on setting up a mail server with unlimited users and domains, with IMAP/Pop access, anti-spam, anti-virus, secure authentication, encrypted traffic, web mail interface and more.

Based on an Ubuntu distribution platform, but instructions are distro generic.
Debian Installing Debian onto USB flash media with everything encrypted
Post date: September 28, 2005, 12:09 Category: Security Views: 228
Tutorial quote: This is a simple procedure for installing Debian GNU/Linux onto a USB key flash media. It includes several configuration changes but tries to stay as close to a default debian install as possible.

This is useful for administrators that need to carry sensitive information or people concerned about their privacy.
Debian An apt-get primer
Post date: April 12, 2005, 13:04 Category: System Views: 90
Tutorial quote: If any single program defines the Debian Linux project, that program is apt-get. apt-get is Debian's main tool for installing and removing software. Working with the .deb package format, apt-get offers sophisticated package management that few Red Hat Package Manager RPM-based distributions can match.

Besides the convenience, an advantage of apt-get is that it reduces the chances of falling into dependency hell, that limbo where software installation fails for lack of another piece of software, whose installation fails for lack of another piece of software, and so on. If you know how Debian's archive system works, and how to choose the sources that apt-get uses, and use a few precautions in your upgrades, then the chances are that dependency problems will never bedevil you. Should you descend into dependency hell anyway, apt-get offers useful tools for climbing out of it.
Unix+clones SSH Port Forwarding Through a Proxy Server
Post date: April 17, 2005, 23:04 Category: Network Views: 40
Tutorial quote: A common use of SSH is port forwarding (tunneling). This use causes traffic directed to a particular port to be sent to a specified port on another computer. Because traffic is sent through SSH, the traffic is encrypted, allowing the transmission of sensitive data through arbitrary services.
