Debian Administration :: 2/2: An introduction to using Puppet
by camel
In our previous introduction to Puppet we covered installing the client and server, such that a small LAN could be configured centrally. Here we'll demonstrate some of the things that can be done with such a setup

I've setup my own system monitoring.
I'm monitoring:

Debian Administration :: Unattended, Encrypted, Incremental Network Backups: Part 1
by sledge & 1 other (via)
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.
Debian Administration :: Using the GPG signature checking with apt 0.6
by sledge
If you're running a Debian Unstable installation you'll likely have noticed that new package installations, and upgrades, are now prompting for confirmation - warning about package checking. This is because the most recent version of APT supports checking package signatures with GPG.
Debian Administration :: Installing Debian onto USB flash media with everything encrypted.
by sledge & 2 others
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 Administration :: Greylisting with Postfix (and other antispam stuff).
by camel
The postgrey package is a greylisting implementation for postfix. It is a breeze to set-up and stopped 89.99% of my spam in conjunction with blacklisting.
Debian Administration :: Password-less logins with OpenSSH
by camel
Because OpenSSH allows you to run commands on remote systems, showing you the results directly, as well as just logging in to systems it's ideal for automating common tasks with shellscripts and cronjobs. One thing that you probably won't want is to do though is store the remote system's password in the script. Instead you'll want to setup SSH so that you can login securely without having to give a password.
Debian Administration :: Tightening PHP Security
by camel & 1 other
There are a lot of Debian systems running PHP code, and in their default state the Debian PHP packages don't tighten up security as much as they could. There are a lot of badly coded scripts out there which can be abused by malicious users. (PHP is in alone in that regard!)
Debian Administration :: Turning on computers remotely
by camel
To save power it's often useful to turn systems off, but of course when you do that you cannot use them! This is especially frustrating when you turn off a machine which is physically remote from you, but it doesn't need to be. Many modern PCs have the ability to be remotely "woken up" and turned on.
