Upgrade Debian Lenny To Squeeze In A Few Simple Steps

Post date: February 8, 2011, 12:02 Category: Installing Views: 2945 Comments
Tutorial quote: One rather old laptop and one server were the test objects for this howto. Both systems do not have any RAID devices and use a simple partition scheme from a default basic Lenny install. If your setup deviates much from this, it's highly recommended to read all details of the Debian Release Notes before you continue. Be warned. All commands are run as root and Debian recommends to use apt-get for the Squeeze upgrade process.

Setting Up A Highly Available NFS Server

Post date: April 1, 2006, 05:04 Category: Network Views: 6800 Comments
Tutorial quote: In this tutorial I will describe how to set up a highly available NFS server that can be used as storage solution for other high-availability services like, for example, a cluster of web servers that are being loadbalanced. If you have a web server cluster with two or more nodes that serve the same web site(s), than these nodes must access the same pool of data so that every node serves the same data, no matter if the loadbalancer directs the user to node 1 or node n. This can be achieved with an NFS share on an NFS server that all web server nodes (the NFS clients) can access.

As we do not want the NFS server to become another "Single Point of Failure", we have to make it highly available. In fact, in this tutorial I will create two NFS servers that mirror their data to each other in realtime using DRBD and that monitor each other using heartbeat, and if one NFS server fails, the other takes over silently. To the outside (e.g. the web server nodes) these two NFS servers will appear as a single NFS server.

In this setup I will use Debian Sarge (3.1) for the two NFS servers as well as for the NFS client (which represents a node of the web server cluster).

Making a DVD from CDs

Post date: December 4, 2005, 16:12 Category: Installing Views: 4170 Comments
Tutorial quote: People have requested to have a single DVD instead of the 5 CD's. The reasons for this are various. I have written a program called makeSUSEdvd that can make the DVD in a very easy manner. First download the CD's. These can be either the NOVELL SUSE CD's or the openSUSE cd's. You do not need to burn them, just put them in one directory with only the 5 CD's in it. You will need the root password. If you do not have that, the program is not good and you should do it by hand.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Fedora 7

Post date: July 10, 2007, 23:07 Category: Installing Views: 3837 Comments
Tutorial quote: This document describes how to install a PureFTPd 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 and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Block ssh brute force attack on OpenSuSe

Post date: June 27, 2009, 09:06 Category: Security Views: 4255 Comments
Tutorial quote: A brute force attack consists of trying every possible code, combination, or password until you find the right one.

As an example, imagine a system which only allows 4 digit PIN codes. This means that there are a maximum of 10,000 possible PIN combinations.
