Alsa Config

Having configured the kernel in the previous stage, you can now fire up the audio controller of your choice (aumix, alsamixer, kmix or gnome-alsamixer) and adjust the volumes to your liking. In my experience, the alsaconf utility will have set the volume to zero and muted levels to start out and following a reboot.

After you have everything configured to your liking, you should store the settings with the command:

 1. /usr/sbin/alsactl store

That will enable you change the settings all you want after saving them, and always be able to fall back to a known [continued…]

Linux Advocacy

Linux Advocacy

Firstly note that this page is *not* designed to be any of the following;

  • A place to moan about the shortcomings of any particular OS or application.
  • Somewhere to argue about the relative merits of one application over another.

What is is envisaged to be is a resource for the ‘Soon-to-be’ Linux user or ‘Newbie’ who needs help in the transition from another OS or platform to Linux. So this will include, but not be limited to;

  • Listing Linux based applications which are roughly equivalent to apps on other [continued…]

Open VPN

This page details setting up secure access to a LAN using the OpenVPN software. This software is designed to offer secure connections to clients on untrusted networks, for example the internet or wireless networks. Unlike the IPSec technologies that involve reconfiguring the TCP/IP stack, OpenVPN runs in userspace and establishes a separate network connection for encrypted traffic. The OpenVPN homepage is at http://openvpn.sourceforge.net.

The scenario detailed in this page is concerned with setting up a Debian Linux system as an OpenVPN server to protect the LAN from unauthorised access and provide VPN bridge [continued…]

Non Root Build Environment

It’s generally considered good practice to compile things as a non-root user. If you’ve unpacked the source in your home directory, this is easy to do – all of the sources will be owned by you. However, if you have co-administrators, or you don’t want to put “system” source packages in your home directory, then you can still compile things as a non-root user. It just takes a little planning and set-up.

We shall assume that you are going to do all of your package compiling in the /usr/local/src directory. Some people use /usr/src for this purpose instead [continued…]

Linux Ntl FAQ

NTL & Linux FAQ

NTL own a lot wires in Hampshire, typically the ones running past your home. Lots of Hampshire Linux users have NTL as their ISP, and while the call centre won’t be able to help you with Linux, the NTL service is fully compatible with Linux and other Unixes.

Binary-only diallers?

When some diallup NTL users who have BT phones had to change dial-up numbers (because of BT), NTL brought out a Binary-only dialler program for Windows and Mac OS. In fact all this does is substitute one diallup number with another, and all [continued…]

PPTPVPN

This page is about setting up a VPN connection to connect a LAN or single client to a PPTP server running Microsoft’s PPTP software. Setting up to connect to a non-MS server generally requires a different configuration.

This is a work in progress – when I’ve succeeded in getting the connection going, I’ll remove this notice and announce the page.

Dramatis personae

The Scene: A (home) network on ADSL behind a NATing firewall, trying to connect to a VPN, giving the home network full access to the “main” LAN over the VPN link.

Inter Mezzo

http://www.inter-mezzo.org/images/intermezzo.gif

InterMezzo is a distributed file system. It allows replication of data stored on a “server” to one or more clients. Unlike other network file systems, e.g. NFS, clients cache the data on a local filesystem. The InterMezzo “server” monitors for changes to its exported filesystem which are then replicated out to the clients. Changes made to the cache on the client can be copied to the server if configured to do so. These properties allow a client system to work without being in contact with the server and without losing the ability to work [continued…]

D Link650 Wireless Card

DWL 650+ Installation Instructions Step by Step

Downloaded the acx100 driver from acx100.sourceforge.net and extract it following the README file. Downloaded the windows driver and dumped firmware in firmware/ directory:

wget ftp://ftp.dlink.com/Wireless/dwl520+/Driver/dwl520+_drivers_307.zip unzip dwl520+_drivers_307.zip cp Drivers/Win2000/WLANGEN.bin firmware/WLANGEN.BIN cp Drivers/Win2000/RADIO0d.BIN Drivers/Win2000/RADIO11.BIN firmware/ mkdir /usr/local/firmware cp firmware/*.BIN /usr/local/firmware/

Back in the acx100 driver directory, type:

make make install

This next bit only needs to be done once. Edit /etc/modutils/local-wireless (on Debian – edit /etc/modules.conf directly on other distributions). For 2.6.x kernels use /etc/modprobe.d/local-wireless or /etc/modprobe.conf on other distributions.
