TrueCrypt Tutorial: Truly Portable Data Encryption
is a free software that encrypts data “on-the-fly”. Right now the newest version released is version 4.3. You can create an encrypted hard drive, a separate partition or a directory with TrueCrypt. It doesn’t simply encrypt the content of files, but their names and the names of the directories they are in as well. Moreover there is no way to check the size of the encrypted directory/HDD/partition. TrueCrypt is available for Windows and Linux.
Installing Beryl Or Compiz Fusion On A Fedora 7 Desktop
This tutorial shows how you can install and use Beryl or Compiz Fusion on a Fedora 7 desktop (the system must have a 3D-capable graphics card). With both Beryl and Compiz Fusion, you can make your desktop use beautiful 3D effects like wobbly windows or a desktop cube.
How to secure an SSL VPN with one-time passcodes and mutual authentication
SSL-based VPNs were designed to eliminate the need for complex configurations on the user's PC. Unfortunately, that was before the dangers of public WiFi networks and tougher regulatory requirements came into being. Thanks to WiFi, many attacks that were difficult are now quite simple. In particular, a man-in-the-middle attack can intercept SSL-encrypted traffic, rendering SSL-based VPNs useless - even if it's protected by a typical one-time password system. The man-in-the-middle can easily feed the one-time password into the SSL-based VPN within the alloted time.
Installing Xen On An Ubuntu Feisty Fawn Server From The Ubuntu Repositories
This tutorial provides step-by-step instructions on how to install Xen on an Ubuntu Feisty Fawn (Ubuntu 7.04) server system (i386). You can find all the software used here in the Ubuntu repositories, so no external files or compilation are needed. 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).
Entering A Safe Mirror When Logging In With Unionfs And Chroot
When reading a 'hint' on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted homedirectory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is a exact copy (mirror) of the system you're working on. Because you're in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).
Postfix Monitoring With Mailgraph And pflogsumm On Debian Etch
This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix (e.g. using amavisd-new). These graphs can be accessed with a browser, whereas pflogsumm ("Postfix Log Entry Summarizer") can be used to send reports of Postfix activity per email.
Configuring Samba 3.0 To Use The ADS Security Mode (CentOS)
The intent of this article is to show you how to configure your Linux machine and Samba server to participate in a Windows 2003 Active Directory domain as a Member Server using Kerberos authentication. This involves using the security = ADS security mode in Samba.
Virtual Hosting With vsftpd And MySQL On Debian Etch
Vsftpd is one of the most secure and fastest FTP servers for Linux. Usually vsftpd is configured to work with system users. This document describes how to install a vsftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine.
Installing And Working With Xoops Under Ubuntu 6.10
I want to show you how to install Xoops on Ubuntu. I used the Ubuntu 6.10 Server Edition, but it will probably work on other systems as well. Xoops is a modern Content-Management-System which can be extended with a variety of modules.
Setting Up Postfix As A Backup MX
In this tutorial I will show how you can set up a Postfix mailserver as a backup mail exchanger for a domain so that it accepts mails for this domain in case the primary mail exchanger is down or unreachable, and passes the mails on to the primary MX once that one is up again.
