Configuring Dynamic DNS & DHCP on Debian Stable

Post date: February 3, 2006, 01:02 Category: Network Views: 3646 Comments
Tutorial quote: For the average home computer user there is no need to install a complex package such as the Internet Software Consortium's BIND DNS or DHCP server, since there are far simpler lower resource tools to use, for example dnsmasq. For those who you wish to learn how to use ISC's BIND and DHCP, for example as a learning exercise, this is how I got it all to work in Debian Sarge, the current stable version of Debian GNU/Linux.

This short article was prompted by my question on the Debian-Administration forum site, where I was able to get some answers to the issues I faced and I did promise to post a solution if I got one.

CLI Magic: OpenSSH + Bash

Post date: January 25, 2006, 20:01 Category: Network Views: 2974 Comments
Tutorial quote: As a system administrator, I have used OpenSSH's piping abilities more times than I can remember. The typical ssh call gets me access to systems for administration with a proven identity, but ssh is capable of so much more. In combination with bash's subshell invocation, OpenSSH can distribute the heavy work, reduce trace interference on a system under test, and make other "impossible" tasks possible. I've even used it to make Microsoft Windows remote administration easier.

In the examples below, I have tried to avoid GNU-specific idioms for tools which have non-GNU counterparts. This practice improves portability of shell scripts in heterogeneous environments.

Setting Up A PXE Install Server For Multiple Linux Distributions With Ubuntu Edgy Eft

Post date: December 20, 2006, 01:12 Category: Installing Views: 4172 Comments
Tutorial quote: This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 6.10 (Edgy Eft). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs. In this article I show how to configure a PXE server that allows you to boot multiple distributions: Ubuntu Edgy/Dapper, Debian Etch/Sarge, Fedora Core 6, CentOS 4.4, OpenSuSE 10.2, and Mandriva 2007.

Monitoring Servers and Clients using Munin

Post date: April 4, 2006, 20:04 Category: Installing Views: 2514 Comments
Tutorial quote: "Munin" means "memory".

Munin the tool surveys all your computers and remembers what it saw. It presents all the information in in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, and quite possibly applications as well. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity wise on all limited resources.

It uses the excellent RRDTool and is written in Perl. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for sdata. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).

Upgrade Debian Lenny To Squeeze In A Few Simple Steps

Post date: February 8, 2011, 12:02 Category: Installing Views: 2364 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.

Tutorial quote: This How-To document guides you through installing ASSP (Anti-Spam SMTP Proxy) on an Ubuntu 10.04 (LTS) Server or Debian 5.0 in the simplest way possible. It *may* work on later versions but I have no way of knowing how these instructions will work for you. Installing Ubuntu/Debian is beyond the scope of this document and it is assumed you already have the core Ubuntu/Debian OS with no predefined software collections installed.
