Recently i got my new Dell Vostro 1510.

Ubuntu 8.04 works out of the box, only my microphone isn’t working, and the speakers aren’t muted, when plugging in the headphone. So the next few post will cover my battle against Ubuntu and the ALSA drivers

First I installed the backports, as this blog post suggests: http://linuxtechie.wordpress.com/2007/10/19/getting-intel-ich8-family-rev-3-sound-card-to-work-in-gutsy/

sudo apt-get install linux-backports-modules-hardy

# not -generic (named different now!)

Edit:

inserting the following line to /etc/modprobe.de/alsa-base did a great job for now:

options snd-hda-intel model=toshiba position_fix=0 enable=yes

The microphone still has a litte problem, as it seems that is faaaaaaaar to loud, so recording with the mic gives me just garbage noise (but i can identify my words [that they start & end] ), but muting the speakers now works!

Edit2:

Microphone now works: just turn down PCM to about 1/3 and increase mic-boost to 100.

Edit3: (5th of July)

Check if no channel is muted (using alsamixer on console!)

So,

wieder einmal in Rästel gelöst!

Meine Netzwerkkarte vom Typ Realtek 8139 hat unter Linux nicht funktioniert. Der Grund: Der Windowstreiber hat das Gerät deaktiviert, und die Linuxtreiber konnten das Gerät nicht mehr aktivieren.

C’t – FAQ

And as this happend more often:

If your Realtek lan-port doesn’t work after running a microsoft os try disabling any power-saving options the realtek windows driver offers! See the link above for screenshots!

Hin und wieder kann es vorkommen, dass man hinter einem Gateway sitzt, der einem nicht erlaubt, gewisse Dienste zu benutzen, oder auf gewisse Server zuzugreifen. Kann man dies jedoch vom Gateway aus tun, so spricht auch nichts dagegen via SSH die Verbindung vom Client über den Gateway zum Server zu tunneln.

Wie geht das?

ssh bietet hier die Möglichkeit einen solchen Tunnel aufzubaue, und zwar mit dem Kommandozeilenargument -L:

ssh -L localport:server:serverport user@gateway

Zum Beispiel:

ssh -L 9000:stupent.at:80 ich@mein.gateway.com

Dadurch kann man nun vom bösen Client aus, der normal nicht auf stupent.at zugreifen darf, mittels http://localhost:9000 zugreifen.

Eventuell hilfts ja wem!
