Snapshot Backups Of Your Desktop With TimeVault
This document describes how to set up, configure and use TimeVault on Ubuntu 7.10. The resulting system provides a powerful backup system for desktop usage. TimeVault is a simple front-end for making snapshots of a set of directories. Snapshots are a copy of a directory structure or file at a certain point in time. Restore functionality is integrated into Nautilus - previous versions of a file or directory that has a snapshot can be accessed by examining the properties and selecting the 'Previous Versions' tab.

How to: Linux configure pound reverse proxy
Pound is a reverse-proxy load balancing server. It accepts requests from HTTP / HTTPS clients and distributes them to one or more Web servers. The HTTPS requests are decrypted and passed to the back-ends as plain HTTP. It will act as:

a) Server load balancer
b) Reverse proxy server
c) Apache reverse proxy etc
d) It can detects when a backend server fails or recovers, and bases its load balancing decisions on this information: if a backend server fails, it will not receive requests until it recovers
e) It can decrypts https requests to http ones
f) Rejects incorrect requests
h) It can be used in a chroot environment (security feature)

Linux install and configure pound reverse proxy for Apache http / https web server

SAMBA (Domaincontroller) Server
This is a detailed description about setting up an Ubuntu based server (Ubuntu 7.10) to act as file- and printserver for Windows(tm) workstations in small workgroups. This howto uses the tdb backend for SAMBA to store passwords and account information. This is suitable for workgroups for up to 250 users and is easier to set up than an LDAP backend.

Why (almost) every Web site needs an RDBMS
Every Web application needs a good database design behind it, and usually much sooner than almost every small-site developer thinks. It's actualy not that hard to configure a simple RDBMS, and good bindings for most back ends almost surely exist for your favorite programming language or framework. Rather than wait, just set up a RDBMS right at the beginning, and work from there.

How to: Linux Demilitarized Zone (DMZ) Firewall
Demilitarized zone, used to secure an internal network from external access. You can use Linux firewall to create DMZ easily. There are many different ways to design a network with a DMZ. The basic method is to use a single Linux firewall with 3 Ethernet cards. The following simple example discusses DMZ setup and forwarding public traffic to internal servers.

Virtual Users And Domains
This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

Parse RDDL Documents with PHP
When working with XML you really need a way to describe a namespace using multiple resources, including DTDs, XML Schemas, XSL stylesheets and software documents. The Resource Directory Description Language (RDDL) allows you to do exactly this! Parse RDDL descriptors with an API in the XML_RDDL package from PEAR, and extract resource information for use in any PHP application.

Time Machine HD Swap: Secret of the Time Machine
Cool.
"I said "void the warranty" and I meant it. The process I went through today means it'll be harder for me to complain to Apple if things get weird, so be cautious! Given the experience I've had, I think HDDs will soon be given easy-access panels, like RAM has, because swapping a 2.5" SATA turns out to be straightforward, and the software, at least as far as Apple goes, is ready for novices"

Ubuntu / Debian Linux: Services Configuration Tool
Your Debian / Ubuntu Linux box security depends upon access to system services (one of many aspects). For example, you may need to provide a web server (Apache service) to serve web pages. However, if you do not need use a service, you should always turn off all unused services to avoid exploits.

Traditionally, Debian provided various tools to manage services. There are various methods for managing access to system services:
a) /etc/init.d/service
b) rcconf
c) update-rc.d etc

Under Red hat and Centos Linux you can use chkconfig command (ntsysv command) to configure Sys V style init script links. There is also service command to stop / start / restart services.

So if you are addicted to the service command under RHEL / CentOS / Mandriva Linux and have wondered what to do in Debian / Ubuntu Linux try sysvconfig package.
