Preventing Brute Force Attacks With BlockHosts On Debian Etch

Post date: September 30, 2007, 09:09 Category: Security Views: 4036 Comments
Tutorial quote: In this article I will show how to install and configure BlockHosts on a Debian Etch 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.

Installing memcached And The PHP5 memcache Module On Debian Etch (Apache2)

Post date: September 11, 2008, 11:09 Category: Optimizing Views: 6281 Comments
Tutorial quote: This guide explains how to install memcached and the PHP5 memcache module on a Debian Etch system with Apache2. memcached is a daemon that can store objects in the system's memory (e.g. results of database queries) which can speed up your web site tremendously. You can use memcached over a network (i.e., install your web application on one server and memcached on another server), but usually you install both on one server to avoid the networking overhead.

Creating Advanced MySQL-Based Virtual Hosts On Lighttpd (Debian Etch)

Post date: August 19, 2008, 10:08 Category: Software Views: 3145 Comments
Tutorial quote: This guide explains how you can create advanced virtual hosts on a lighttpd web server on Debian Etch that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a database), this method allows to store individual configuration directives for each vhost in the MySQL database.

How To Patch BIND9 Against DNS Cache Poisoning (Debian/Fedora/CentOS)

Post date: July 29, 2008, 09:07 Category: Security Views: 3594 Comments
Tutorial quote: Dan Kaminsky earlier this month announced a massive, multi-vendor issue with DNS that could allow attackers to compromise any name server - clients, too. These two articles explain how you can fix a BIND9 nameserver on Debian Etch and Fedora/CentOS so that it is not vulnerable anymore to DNS cache poisoning.

How to Install Adobe Flash in Debian Etch/Lenny/Sid

Post date: January 5, 2009, 18:01 Category: System Views: 3976 Comments
Tutorial quote: In this tutorial we will see how to install Adobe Flash in Debian Etch/Lenny/Sid. Adobe Flash (previously called "Macromedia Flash"') is a multimedia platform created by Macromedia and currently developed and distributed by Adobe Systems. Since its introduction in 1996, Flash has become a popular method for adding animation and interactivity to web pages; Flash is
commonly used to create animation, advertisements, and various web page components, to integrate video into web pages, and more recently, to develop rich Internet applications.

Virtualization With Xen 3.3.1 On Debian Etch

Post date: February 12, 2009, 12:02 Category: Installing Views: 2602 Comments
Tutorial quote: This tutorial provides step-by-step instructions on how to install Xen 3.3.1 on a Debian Etch (4.0) system. 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). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch

Post date: August 24, 2008, 11:08 Category: Installing Views: 3261 Comments
Tutorial quote: This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.

Setting Up Master-Master Replication On Four Nodes With MySQL 5 On Debian Etch

Post date: November 20, 2008, 12:11 Category: Miscellaneous Views: 2900 Comments
Tutorial quote: This tutorial explains how you can set up MySQL master-master replication on four MySQL nodes (running on Debian Etch). The difference to a two node master-master replication is that if you have more than two nodes, the replication goes in a circle, i.e., with four nodes, the replication goes from node1 to node2, from node2 to node3, from node3 to node4, and from node4 to node1.

Creating Simple Virtual Hosts With mod_mysql_vhost On Lighttpd (Debian Etch)

Post date: August 7, 2008, 09:08 Category: Installing Views: 2915 Comments
Tutorial quote: This guide explains how you can use mod_mysql_vhost to create simple virtual hosts on a lighttpd web server on Debian Etch. With mod_mysql_vhost, lighttpd can read the vhost configuration from a MySQL database. Currently, you can store the domain and the document root in the MySQL database which results in very simple virtual hosts. If you need more directives for your vhosts, you would have to configure them in the global section of lighttpd.conf, which means they would be valid for all vhosts. Therefore, mod_mysql_vhost is ideal if your vhosts differ only in the domain and document root.

Server Monitoring With munin And monit On Debian Etch

Post date: May 13, 2007, 21:05 Category: System Views: 3808 Comments
Tutorial quote: In this article I will describe how you can monitor your Debian Etch server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that let you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
