In this howto, the host system is running Debian Etch, while the guest system to be installed will be using Debian Lenny. If you are concerned about your privacy, you might want to consider using hard disk encryption to protect your valuable private data from spying eyes. Usually, the easiest way would be to use your distribution's installer to set up a fully encrypted system; I think most recent Linux distributions support this. However, when you are using XEN to provide virtualization, there are situations where you might not want to encrypt your whole computer with all guest instances, but instead only encrypt one OS instance. This howto will deal with exactly this situ falko Sun, 03 May 2009 10:41:05 GMT http://www.howtoforge.com/creating-encrypted-ftp-backups-with-duplicity-and-duply-on-debian-squeeze When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and duply to create encrypted backups on the provider's remote backup server over FTP. duply is a duplicity wrapper script that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords). falko Sun, 08 Jul 2012 08:00:17 GMT http://www.howtoforge.com/ftp-backups-with-duplicity-ftplicity-debian-etch When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords). falko Tue, 18 Dec 2007 12:49:53 GMT http://www.howtoforge.com/ubuntu_dm_crypt_luks Today security is one of the key aspects in our daily life - sometimes conscious, sometimes unconscious. Security has many aspects and one of them is computer security or security of your or your business' computer data. In this tutorial I will show how to encrypt a whole disk drive using (X)Ubuntu Feisty, dm-crypt, and LUKS. falko Wed, 11 Apr 2007 16:42:12 GMT http://www.howtoforge.com/how-to-encrypt-directories-partitions-with-ecryptfs-on-debian-squeeze eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux. You can use it to encrypt partitions and also directories that don't use a partition of their own, no matter the underlying filesystem, partition type, etc. This tutorial shows how to use eCryptfs to encrypt a directory on Debian Squeeze. falko Tue, 26 Jul 2011 11:16:54 GMT http://www.howtoforge.com/how-to-encrypt-mails-with-ssl-certificates-s-mime This article is about how to use the S/MIME encryption function of common e-mail clients to sign and/or encrypt your mails safely. S/MIME uses SSL certificates which you can either create yourself or let a trusted certificate authority (CA) create one for you. falko Sun, 11 Dec 2011 11:14:52 GMT http://www.howtoforge.com/how-to-set-up-mysql-database-replication-with-ssl-encryption-on-centos-5.4 This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures. falko Thu, 18 Feb 2010 13:41:56 GMT http://www.howtoforge.com/how-to-set-up-mysql-database-replication-with-ssl-encryption-on-ubuntu-9.10 This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave).

For security reasons, communication between phpMyAdmin and any remote MySQL server is using SSL encryption (this is not necessary for a local MySQL server since communication between phpMyAdmin and MySQL is not leaving the server). phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the World Wide Web. phpMyAdmin supports a wide range of operations with MySQL. falko Thu, 20 Sep 2012 06:50:49 GMT http://www.howtoforge.com/setting-up-truecrypt-5.1a-on-debian-etch-gnome This document describes how to set up TrueCrypt 5.1a on Debian Etch (GNOME). Taken from the TrueCrypt page: "TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc)." falko Tue, 13 May 2008 10:58:20 GMT
