According to [Only Ubuntu](http://onlyubuntu.blogspot.com/2008/05/auto-mounting-internal-drives-in-ubuntu.html), to
enable auto-mounting of internal drives on bootup, edit the file `/etc/hal/fdi/policy/preferences.fdi` and change
the line
<merge key="storage.automount_enabled_hint" type="bool">false</merge>
to this:
<merge key="storage.automount_enabled_hint" type="bool">true</merge>
From now on, internal drives should appear on your Desktop.

At work we have the [Kerio Mailserver](http://www.kerio.com/mailserver) Appliance for VMware which is based on Fedora
Core 6. Since they use the ugly `[yum](http://yum.baseurl.org/)`, I decided to install `[apt-rpm](http://apt-rpm.org/)`.
I'm still missing something like `[aptitude](http://algebraicthunk.net/~dburrows/projects/aptitude/)`, but it is okay now.
`apt-rpm` expects some `*.list` files in the `/etc/apt/sources.list.d/` directory - as does the Ubuntu `apt-get`.
Repositories
============
Since I had some time to find all repos, here's ist an overview:
* **os.list** (pre-installed, shortened to the neccessary ones)
# Name: Operating system and updates
### Fedora Core Linux
#repomd http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH)/core
#repomd http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH)/updates
rpm http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH) core updates
#offline: repomd http://download.fedora.redhat.com/pub/ fedora/linux/core/$(VERSION)/$(ARCH)/os/
repomd http://download.fedora.redhat.com/pub/ fedora/linux/extras/$(VERSION)/$(ARCH)/
#offline: repomd http://download.fedora.redhat.com/pub/ fedora/linux/core/updates/$(VERSION)/$(ARCH)/</code>
* **dries.list**
# Name: Dries Repository
#repomd http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/linux/$(VERSION)/$(ARCH)/dries
rpm http://apt.sw.be fedora/$(VERSION)/en/$(ARCH) dries</code>
* **freshrpms.list**
# Name: freshRPMs
# core and updates are used in os.list
rpm http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH) extras freshrpms</code>
* **livna.list**
# Name: livna
repomd http://rpm.livna.org fedora/$(VERSION)/$(ARCH)
repomd http://rpm.livna.org fedora/testing/$(VERSION)/$(ARCH)</code>
* **remi.list**
# Name: Les RPM de Remi
repomd http://rpms.famillecollet.com fc$(VERSION).$(ARCH)</code>
The difference between the **`rpm`** and the **`repomd`** is simple: A `repomd` points to a single repository whereas
`rpm` can point to different in one line. Example:
repomd http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH)/core
repomd http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH)/updates
is exactly the same as
rpm http://ayo.freshrpms.net fedora/linux/$(VERSION)/$(ARCH) core updates
Notice the two last words in the last example. The resemble the two directories of the two `repomd` statements. You
know it is a repository if the path contains a folder `repodata`, such as [this one](http://ayo.freshrpms.net/fedora/linux/6/i386/core/repodata).
Knowing that, you can find more Repos using [Google](http://google.com/search?q=allinurl%3A+i386+repodata+repomd+%2B6+fc+OR+fedora) with an
[advanced query](http://letmegooglethatforyou.com/?q=allinurl%3A+i386+repodata+repomd+%2B6+fc+OR+fedora).

title: apt-get Errors

If you get the following error while updating the package list:
W: GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 632D16BB0C713DA6
You need to manually update the key. The key-ID is the last 8 digits of the key, in this case: *0c713da6*.
Now fetch the key from the Ubuntu keyserver:
gpg --keyserver keyserver.ubuntu.com --recv 0c713da6
And finally add the new key to the apt-keyring:
gpg --export --armor 0c713da6 | sudo apt-key add -
You can even automate this a bit with the following shell script:
{% highlight bash %}
#!/bin/bash
KEYID=${1:-8}
gpg --keyserver keyserver.ubuntu.com --recv $KEYID
gpg --export --armor $KEYID | sudo apt-key add -
{% endhighlight %}
This will only use the last 8 digits of the first parameter as KEYID. So you can even call it with the full 16 digits.

To create ASCII art or just some colorful things with lots of ANSI color codes, there's the package
[aewan](apt://aewan) - [Ascii-art Editor Without A Name](http://aewan.sf.net/).
aewan itself saves the files in an own format. But there's the tool `aecat` which lets you cat those files - and thus
you can also write the output into another file to get a normal file with ANSI codes which can be shown using the
normal `cat`.
aecat colorful.aew > colorful.txt

title: ALSA Sound Card Order

The default soundcard to be used with ALSA is that with the index 0 in `/proc/asound/cards`. Usually this is the first
found sound device.
If you want to change this order, you have to find out the name of the kernel module used for that card and then add
the desired `index` to it in a modprobe file. I appended these lines to my `/etc/modprobe.d/alsa-base.conf`:
options snd-hda-intel index=-2
options snd-usb-audio index=0
This way, the internal sound card (which was the primary one) now gets some other index and the USB mini speakers get
the index 0 and therefore become the new default device for any sounds.

title: ALSA → PulseAudio for Flash and others
layout: default

One huge problem in a standard Ubuntu install is that not all programs are actually using the PulseAudio daemon but
instead still use ALSA. This is especially true with the [flashplugin](apt://flashplugin-installer). Since PulseAudio
and ALSA can't use the hardware device at the same time, they block each other which leads to hangs and maybe even
crashes of programs (e.g. browser).
The fix is relatively easy and consists of telling ALSA to use its `pulse` plugin for output - which routes the sound
to PulseAudio instead of directly to hardware. It is explained at [pulseaudio.org](http://pulseaudio.org/wiki/PerfectSetup#ALSAApplications).
Basically you only have to create a file `/etc/asound.conf` with these few lines:
~~~
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}
~~~
This tells all ALSA apps to use the PulseAudio output by default. Some notes may also be found on [wiki.ubuntu.com](https://wiki.ubuntu.com/PulseAudio).
You should also check that you have installed [libsdl1.2debian-pulseaudio](apt://libsdl1.2debian-pulseaudio) instead of the `-alsa` one.

If you wish to change the behavior upon pushing e.g. the power button, you can edit the config files located in
`/etc/acpi/events/`. To disable the power button, you would edit the file `powerbtn` there and change the `action` line
to:
{% highlight ini %}
action=/bin/true

[apt-cacher](apt://apt-cacher) and [apt-cacher-ng](apt://apt-cacher-ng) both act as a proxy between `apt-get` or
`aptitude` and the Debian repositories. It stores the packages upon first request and loads them from cache on further
ones. If you have 2 or more Ubuntu PCs in your network, you can save a massive amount of bandwidth with it.
Installation
============
1. Install the package [apt-cacher](apt://apt-cacher) or [apt-cacher-ng](apt://apt-cacher-ng)
1. Make sure it is running (sometimes you might have to edit a file `/etc/default/apt-cacher` or
`/etc/default/apt-cacher-ng` to enable it)
1. Now do the following on **ALL PCs** in your network - including the one with `apt-cacher(-ng)` installed:
* Create a file `/etc/apt/apt.conf.d/01proxy` with the following contents: (replace the IP by the IP of the PC with
`apt-cacher(-ng)` installed)
Acquire::http::Proxy "http://192.168.0.1:3142";
* Create a file `/etc/apt/apt.conf.d/99clean` with the following contents: (this will keep the local apt-cache clean)
DPkg::Post-Invoke {"/usr/bin/find /var/cache/apt/archives/ -type f -mtime 2 -name *.deb -exec /bin/rm -f {} \; || true";};
That was it. All packages will be cached on the `apt-cacher(-ng)`-PC and the local caches will be kept clean.
