Debian - Realtek RTL8111/8168 on Intel D945GCLF2


Having upgraded a D945GCLF2 motherboard to Debian Squeeze, I started to have lot of troubles & serious problems with the integrated network interface Realtek RTL 8111/8168.

For example, the mt-daapd music server was totally unstable, having difficulty to serve more than one Roku music player. The multicast functionality was totally broken.

After some search, it appears that the driver used by the 2.6.26 kernel for that NIC was the wrong one. Instead of using a proper r8168.ko module, the 2.6.26 kernel was using the r8169.ko module.

If your kernel is 2.6.30+, you don't need to follow this guide anymore as the kernel includes a proper driver.

If you update your kernel to 2.6.30+ and you had followed this guide before, be careful to remove the blacklist of r8169 module in /etc/modprobe.d/blacklist.conf before reboot, or you won't get any network support ...

Debian - Install a server on a Compact Flash memory


This article will explain how to install Debian on a server using a Compact Flash memory card as a primary drive. All the above procedures are based on the Lenny distribution, but they should work on other Debian flavours and even for Ubuntu.

The first question to ask is : Why to do that ?

When you install such a server, after sometimes you realize that it has become a backbone in your house as it hosts :

  • a family web site
  • a music server for appliances like Roku Soundbridge
  • a file server for other PCs
  • a web based torrent manager & amule manager
  • an access filter proxy for the kids surf
  • an asterisk telephony exchange
  • ...

Then, you start to have nightmares about the fact that your server's hard disk may fail and that you will need to reinstall everything.

One simple, efficient & cheap solution is to replace your hard disk by a Compact Flash memory in association with an IDE to CF adapter. As CF memory have no mecanical parts, they are known to be much more reliable.

But, on the other side, they are known to have limited write cycles (between 100 000 and 1 million times).

Debian - Convert a EEE 701 as a server with embeded UPS

EEE 701 & Debian

Having a spare Asus EEE 701 netbook, I've converted it as a home server for music streaming, DVB-T streaming, web server, ...
This netbook is consuming very little power and is running under Debian in console mode without any graphical interface.

As every netbook, the EEE 701 is having an inbuilt battery, which can be used a very KISS (Keep It Simple and Stupid) Uninterrupted Power Supply system.

With proper scripts, it is possible to detect power failure and to follow the battery level &  to initiate a clean shutdown process when battery level is too low after a long power failure.

This article will explain how to :

  • detect power failure
  • check battery level
  • start a shutdown process when battery level is reaching predefined low level

With that, your server will shutdown properly whatever happens with its power supply.

Debian - Automatic backup with USB disk


You are hosting a server (or a workstation) with some important files that sould be backed-up regularly on some external storage ?

This article will explain how to use the fantastic possibilities of UDEV & RSync to automatise some files backup on an external USB hard disk.

The concept is as follow :

  1. You insert an external USB disk on one of your server USB port
  2. Your server recognise the inserted disk & mount it
  3. According to some backup rules associated with that specific disk, your server starts a differential backup
  4. When backup is over the disk is unmounted & the server beeps you the indicate that the backup is over

And, with this approach, you can use as many backup disks as you want, as the backup is done according to rules associated with a specific disk.

We will use :

  • UDEV to recognize the disk and start the associated backup script
  • RSync to do a very fast differential backup

This setup has been done on Debian Squeeze, but it should be compatible with any following version.
