Installing MyDNS-NG & MyDNSConfig On Debian Squeeze

This tutorial will describe how to install and configure MyDNS-NG and MyDNSConfig 3 on Debian Squeeze. MyDNS-NG is a DNS server that uses a MySQL database as backend instead of configuration files. The advantage is that MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted. A secondary nameserver can be easily set up by installing a second instance of MyDNS that accesses the same database or, to be more redundant, uses the MySQL master / slave replication features to replicate the data to the secondary nameserver.

Host Based Intrusion Detection - Samhain

This article describes in some detail how to install Samhain, the host based intrusion detection system. I am not going to ramble on about what host based intrusion detection is or why to use it, as there are plenty of articles already covering those subjects. This article is just to show you how to get Samhain up and running in a client / server configuration with a couple bells and whistles thrown in for fun.

Enabling SquirrelMail For Your Web Sites On An ISPConfig 3 Server (Debian Lenny)

Lots of people have reported problems (such as getting 404 Not Found errors) using the SquirrelMail webmail package in their web sites created through ISPConfig 3. If you have followed the "Perfect Server" guides for ISPConfig 3, you have SquirrelMail already installed, but if you are still having the same problems, then this guide is for you. This guide explains how to configure SquirrelMail on a Debian Lenny server so that you can use it from within your web sites (created through ISPConfig).

Helping The Random Number Generator To Gain Enough Entropy With rng-tools (Debian Lenny)

You might know this situation: you want to generate a GPG or SSL key, and during that operation, your system tells you that no more random bytes are available and that it needs to collect more entropy, and you are stuck. This short guide tells you how to solve this problem with the package rng-tools on Debian Lenny.

Preventing Brute Force Attacks With BlockHosts On Debian Lenny

In this article I will show how to install and configure BlockHosts on a Debian Lenny system. BlockHosts is a Python tool that observes login attempts to various services, e.g. SSH, FTP, etc., and if it finds failed login attempts again and again from the same IP address or host, it stops further login attempts from that IP address/host. By default, BlockHosts supports services that use TCP_WRAPPERS, such as SSH, i.e. services, that use /etc/hosts.allow or /etc/hosts.deny, but it can also block other services using iproute or iptables.

The Perfect Desktop - Linux Mint Debian 201009

This tutorial shows how you can set up a Linux Mint Debian 201009 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. While the "normal" Linux Mint editions are based on Ubuntu, Linux Mint Debian 201009 is a Linux distribution based on Debian Squeeze (testing); its aim is to look identical to the main edition and to provide the same functionality while using Debian as a base.

Putting Varnish In Front Of Apache On Ubuntu/Debian

Varnish is an open source "web accelerator" which you can use to speed up your website. It can cache certain static elements, such as images or javascript but you can also use it for other purposes such as Loadbalancing or some additional security. In this tutorial we will focus on the latter one. In this mode, Varnish will stop incomplete HTTP requests from reaching your Apache webserver.

How To Install OpenQRM 4.7 With LXC Containers In Debian Squeeze/Lenny: Step By Step

This is a tutorial for installing OpenQRM 4.7 with LXC containers in Debian Lenny which can further be used for installing ISPConfig3 at the container level. OpenQRM 4.7 was released on September 30, 2010 with LXC support. Wonderful product. Videos of this enterprise grade datacenter management framework are available at http://openqrm.com/?q=node/183. I hope that this information is useful to those who are interested. And thanks to Matt and OpenQRM developers for the hard work!

The Perfect Server - Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]

This tutorial shows how to prepare a Debian Lenny (Debian 5.0) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This tutorials differs from The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3] in that I use BIND and Dovecot here instead of MyDNS and Courier (of course, the other two variants - BIND & Courier or MyDNS and Dovecot are possible as well).

How To Configure PureFTPd To Accept TLS Sessions On Debian Lenny

FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to configure PureFTPd to accept TLS sessions on a Debian Lenny server.
