Update Alternatives

Introduction

There’s a rather interesting feature about Debian that many people don’t know about. Debian is able to handle “groups” of similar applications. It’s installed by default (part of the base-system in fact) and is quite often used by the post-configuration of installed packages.

How does it work?

The alternatives for a program are listed in /etc/alternatives. While these are not to be removed manually, this directory holds symlinks for each application that has an alternative. This includes symlinks to the binary itself, and to any relevant manpages that might exist for it.

Apt Proxy

Apt-proxy is a simple program that caches downloaded Debian packages. By setting up multiple client computers to use the same apt-proxy, requested packages are only downloaded from the remote server once and cached. This decreases the load on the remote server and improves the speed with which the apt-proxy clients can get hold of the latest Debian packages! Like most network programs, apt-proxy uses the client and server model. In this case, the computer running apt-proxy is the server and the computers using the server as their source for updates and upgrades are clients.

Note that the current [continued…]

Printing

Printing with Linux can appear quite complex to setup but can be as simple as installing cups, and then installing a printer from the web interface at http://localhost:631

Local printers are easily setup.

However, I wanted to print using a networked printer that is on a Windows2000 system. This done by:

Windows Box: Install the printer and setup a share. Install “Other Network File and Print Services” from the Add/Remove Programs -> Windows Components list. Ensure that this service, called TCP/IP Print Server is started, and setup to start automatically.

User Mode Linux

User Mode Linux

User Mode Linux is a way of running more instances of Linux on your existing Linux system. It runs as a program, called simply, linux. It might help to see a picture:

{{{ __________________________ | | | Linux (host) | | ________________ | | | | | | | User Mode | | | | Linux | | | |________________| | |__________________________|

}}}

Why would anyone want to do that?

It’s a safe way to test things without installing Linux on another machine, or fiddling with disk partitions or having to reboot [continued…]

CIFS

Setting up cifs client to talk to Windows 2000/XP/2003 machines.

Common Internet File System (CIFS) is the protocol that Microsoft are gradually replacing all SMB communications with. From http://de.samba.org/samba/ftp/docs/faq/Samba-meta-FAQ-3.html :

“If you consider CIFS as a backwardsly-compatible refinement of SMB that will work reasonably efficiently over the Internet you won’t be too far wrong.”

Note: All testing done using Debian unstable (Sid) with 2.6.2 kernel with option CONFIG_CIFS=y.

Head to http://cvs.samba.org/cgi-bin/cvsweb/samba/source/client/mount.cifs.c and grab the latest source (1.7 at time of writing). Compile the source into a binary and move it into /sbin

Knoppix Debian

Introduction

This page details the steps needed to get Knoppix running as a pure Debian system.

The Procedure

The following is a modified extract of an e-mail I sent to HantsLUG

Knoppix, like Debian, uses its own packages and specific .debs, which are nothing to do with Debian at all. Because of this, the route into Debian is controlled from the file /etc/apt/sources.list . This lists the location of the repositories where all the packages are so that apt can access them. My version of /etc/apt/sources.list for my version of Knoppix relies heavily on the [continued…]

DVB Aver Media

This is work in progress THIS IS BROKEN

Apologies to those people thinking this page would answer all their questions. I currently don’t have the card working. When I next get some hacking time it’ll go in another box, and see if it fares any better…

Although it sounds like it is fully up and running, I’m still compiling, I’m writing my thoughts as I go along, so I don’t forget them!

I have an Avermedia AVerTV DVB-T card in my debian(unstable)/freevo mini-itx based set-top box. I chose this card as it appears to be [continued…]
