Preventing Brute Force Attacks With BlockHosts On Debian Lenny
Author: Falko Timme • Tags: debian, security • Comments: 0
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.

Author: Falko Timme • Tags: desktop, ubuntu • Comments: 22
How To Install Google Earth On Ubuntu 10.10 In previous Ubuntu versions, there was a Google Earth .deb package available in the Medibuntu repository; unfortunately there is no such package for Ubuntu 10.10 (Maverick Meerkat). While it is possible to install the Google Earth package for Ubuntu 10.04 on Ubuntu 10.10, there is another way of installing Google Earth on Ubuntu 10.10. The method described in this tutorial will create a Google Earth .deb package for Ubuntu 10.10 from which Google Earth can be installed.

The Perfect Desktop - Linux Mint 10 (Julia)
Author: Falko Timme • Tags: desktop, ubuntu • Comments: 9
The Perfect Desktop - Linux Mint 10 (Julia) This tutorial shows how you can set up a Linux Mint 10 (Julia) 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. Linux Mint 10 is a Linux distribution based on Ubuntu 10.10 that has lots of packages in its repositories (like multimedia codecs, Adobe Flash, Adobe Reader, Skype, Google Earth, etc.) that are relatively hard to install on other distributions; it therefore provides a user-friendly desktop experience even for Linux newbies.

How To Set Up An Active/Passive PostgreSQL Cluster With Pacemaker, Corosync, And DRBD (CentOS 5.5)
Author: rafatmb • Tags: centos, high-availability • Comments: 8
How To Set Up An Active/Passive PostgreSQL Cluster With Pacemaker, Corosync, And DRBD (CentOS 5.5) This article explains how to set up (and monitor) an Active/Passive PostgreSQL Cluster, using Pacemaker with Corosync and DRBD. We use two nodes, one active (that answers requests from apps) and the other on passive mode. If the active server is down, the passive one will automatically take its position (being the active node). We are using the CentOS 5.5 (64bits) distribution, but it will probably work on Fedora (and Red Hat, for sure) as well.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 10.10)
Author: Falko Timme • Tags: antivirus, email, postfix, ubuntu • Comments: 14
Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 10.10) 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'll 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. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

The Perfect Server - Fedora 14 x86_64 [ISPConfig 2] This is a detailed description about how to set up a Fedora 14 server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable) with PHP5/Ruby/Python, Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 64-bit version of Fedora 14, but should apply to the 32-bit version with very little modifications as well. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).
