Linux Bahamas

If you are new to Linux and would like to learn more about it this book is likely to be a good investment. It is one of the classic getting-started with Linux books. The text is well written and easy to follow. Every few years it is updated with current information and a new edition is released. Here are some of the topics covered in this book:

Dovecot passwd-file Based Virtual Users

To setup Dovecot using passwd-file the following steps should be taken:

• Use the dovecotpw program to generate passwords for users
• Create a file to contain users and passwords
• Configure Dovecot to use the passwd-file to lookup virtual users

Pbuilder is a automated package building tool for Debian. It can build packages for any of the Debian distributions. It also handles package dependencies needed for the build automatically. It can be a very handy tool. The following is an explanation of why you might want to use pbuilder for building Debian packages.

Building Packages For Stable, Testing, or Unstable

I tried the cleaned up patch provided by Steve Langasek. I applied the patches to 2.6.18.2 kernel sources. The patches applied without any issues. However the kernel failed to compile with the following errors:

In file included from include/asm/io.h:250,
from include/linux/dmapool.h:14,
from include/linux/pci.h:564,
from arch/alpha/kernel/alpha_ksyms.c:16:
include/asm/core_titan.h: In function 'titan_ioportmap':

Howto Setup Apache Virtual Hosts

This article relates to Apache2 running on Debian GNU/Linux.

Install Apache2

bash ~# apt-get install apache2

Use Default Config for New Virtual Host

Change directories to the site-available directory in the apache configuration
directory.

bash ~# cd /etc/apache2/sites-available/

There is a default site in this directory. To create a new site just cp the
default one to the name of your new site.

bash ~# cp default www.example.com

Installing Debian GNU/Linux on the Alpha DS25

Hello everyone. I'm back with my two cents regarding installing Debian GNU/Linux on the Alpha DS25. Let me explain the problem as best I can.

The Problem

On Alpha Titan type systems there is a problem in the linux kernel which causes most distributions to be unbootable. I am only a amatuer coder and I cannot begin to describe the problem and how to fix it. I can only say that I tried to boot Debian, FreeBSD, and OpenBSD which all failed.

The Challenge

I recently aquired two alpha DS25 servers. So of coures I wanted to run my favorite linux distribution on them which is Debian GNU/Linux. However Debian will not boot on these machines. Sucks don't you think? There are probably some other ways to get Debian installed on these machines. I will attempt them and updated this article based on my experiments. Hopefully others will find the information I provide here in this article valuable if they also have alpha servers and are struggling with the same challenge.

CentOS and Alpha Core 2

Using virtual users/groups for ftp access is better because it allows ftp users/groups that are not actually system users/groups. This means if an ftp user/group is compromised only the ftp user/group login is obtained. There is no compromise of actual system accounts.

Configuration of the proftpd.conf File

Add these lines to /etc/proftpd/proftpd.conf after the
DenyFilter \*.*/' line.

Authentication Files
The settings below tell proftpd what authentication method to use and which files contain user/group information.

File: proftpd.conf

Mini-itx looks like a cool platform. Small boards that have tons of nice features. These little systems could be used as a 3 or 4 interface linux firewall, pvr/dvr systems or other various media systems, web servers, and the list goes on.

Lately I have been using git for managing source code repositories. Git is a directory content manager. Most people would use git to manage source code repositories. Git is very fast and efficient even when working with large projects.

Cogito is a set of higher level tools that you can use to manage your git repositories. Cogito makes using git more user friendly.
