Preventing Brute Force Attacks With Fail2ban On Debian Etch
In this article I will show how to install and configure fail2ban on a Debian Etch system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.
The Perfect Desktop - Debian Etch (Debian 4.0)
With the release of Microsoft's new Windows operating system (Vista), more and more people are looking for alternatives to Windows for various reasons. In this tutorial I will show people who are willing to switch to Linux how they can set up a Linux desktop (Debian Etch in this article) that fully replaces their Windows desktop, i.e. that has all 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 runs also on older hardware, and the best thing is: all software comes free of charge.
Virtual Hosting With Proftpd And MySQL (Incl. Quota) On Debian Etch
This document describes how to install a Proftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota with this setup.
How To Install VMware Server On Debian 4.0 (Etch)
This tutorial provides step-by-step instructions about how to install the free VMware Server (version 1.0.2) on a Debian Etch system. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free). In this article we use Debian Etch (4.0) as the host operating system.
Debian 4.0 (Etch) Samba Standalone Server With tdbsam Backend
This tutorial explains the installation of a Samba file server on Debian Etch and how to configure it to share files over the SMB protocol as well as adding users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has its own home directory that is accessible via SMB protocol and all users have a shared directory with read/write access.
The Perfect Setup - Debian Etch (Debian 4.0)
This tutorial shows how to set up a Debian Etch (Debian 4.0) based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Debian Etch, but should apply to the 64-bit version with very little modifications as well.
How To Harden PHP5 With Suhosin (Debian Etch/Ubuntu)
This tutorial shows how to harden PHP5 with Suhosin on Debian Etch and Ubuntu servers. From the Suhosin project page: "Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections."
Building DVD Images Of Ubuntu Repositories
This howto offers a simple way of creating DVD images of Debian or Ubuntu http/ftp repositories. Ubuntu doesn't offer DVDs ready to download with its main, universe, multiverse and/or restricted repositories. With the contents of this howto you can do it yourself. Having the Ubuntu or Debian repositories on DVD can be useful for those users who don't have access to the Internet where they have their Ubuntu installed but have access somewhere else to download the repository and build and burn the DVDs.
How To Set Up suPHP On A Debian Sarge Based ISPConfig Server
With this howto I explain how to set up suPHP on a Debian based ISPConfig server with php4. Mainly, it is based on Falko's howto http://www.howtoforge.com/apache2_suphp_php4_php5. Within the forums on Howtoforge, lots of information about "setting up suphp" can be found. However, this information is spread all over the forums, so it is not very clear how to set up suphp on an ISPConfig server. It was the reason for me to write this howto. When you've setup suPHP on your ISPConfig server, you are able to run the PHP scripts under the admin user of the website instead of www-data.
Bluetooth PAND (Personal Area Network) Howto For Debian Etch
I wanted to access the internet over bluetooth instead of GPRS/3G network from my mobile phone (SE K800i). After a lot of searching I couldn't find a clear explanation as how to accomplish this. I did manage to set it up with Windows XP, using the "Personal Area Network" in the bluetooth utility and doing internet connection sharing. After another fruitless search, I managed to figure out how to make a bluetooth internet profile instead of GPRS or 3G on the phone. Since I work in Linux most of the time, I decided to have a go and do it with Debian, my workstation's main OS. After spending a few hours, I had it working using the steps below.
