I’m playing with a script that moves files between two directories and does that by piping two tar commands, so called Fast Copy.

You need zenity to see the progress bar, it is a work in progress as there are some bugs, eg when you click “cancel” the two tar child processes are not killed for some reason, I couldn’t get the correct exit code that probably gets lost somewhere.

Probably in the future I’ll write a better notification.Suggestions and modifications are wellcome.

Ogni qualvolta ci si collega ad internet viene assegnato un indirizzo ip pubblico al proprio computer/router, in Italia quasi tutte le connessioni adsl private hanno un ip dinamico che camba tutte le volte che ci si riconnette. Può tornare comodo conoscere questo ip per poter raggiungere il proprio computer dall’esterno ( lavoro, università ) e per evitare di doverselo scrivere su un “post it” tutte le volte che si accende il modem è possibile utilizzare un dns dinamico .

Razionale

1. iscriversi ad un servizio di dns dinamico, si potrà scegliere un dominio di terzo livello ( terzolivello.secondolivello.it) a cui associare l’indirizzo ip del computer.
2. iscriversi a dnsomatic che provvederà a fornire a tutti i servizi che si usano (come i servizi di dns dinamico ma anche altri come opendns) l’indirizzo ip del computer
3. usare un client che al cambio dell’indirizzo ip avvisa dnsomatic

I decided to keep ubuntu even if I don’t like this new release ( hardy ) at all. When it came out it used to hang for no reason , the new kernels seem to have solved the issue.

I had two big problems, I couldn’t hibernate/suspend and I couldn’t switch to the ttys with Alt+F1 for example.

Starting from the latter I realized that the nvidia-glx package instead of the nvidia-glx-new does the job. Since I don’t know the difference between the two packages and I really don’t care to have the newest nvidia driver I consider this problem fixed.

Now suspend works and not sometimes or just one time like it used in the past, I had to change some config options in /etc/default/acpi-support

SAVE_VBE_STATE=false
POST_VIDEO=false
SAVE_VIDEO_PCI_STATE=true

Hiberating is still a problem or better waking up from hibernation is a huge deal on my laptop. It does hibernate and it tries to wake up during next boot but when X starts everything freeze. It seems a kernel or xorg problem because I can’t turn on/off the capslock led. Here’s the bug I’ve filled, hopefully someoene will look at it.

In the past conky had some built in features regarding mldonkey that have been dropped later. I launch a script that uses netcat to do the same thing ( at least what I need).


#! /bin/sh
USER=user ## mldonkey user
PASS=pass ## mldonkey password for user
HOST=192.168.1.2 ## host where mldonkey is running
PORT=4000 ##port
(echo "auth $USER $PASS";echo $1;echo q) | nc $HOST $PORT

and then for conkyrc

${execi 50 ml_command bw_stats|grep Down|awk -F " " '{print $1,$2,$3,$10,$11,$12}'}


I finally have sound , nice to hear

My laptop is a Packard Bell Easynote MX51-B-058 and is shipped with with Realtek ALC660 HD Audio sound chip, lspci gives the following:

even if it says “Audio device:nVidia” you must use the snd-hda-intel module to make it work and actually ubuntu loads it during startup but sound still doens’t come out from speakers or headphones That module supports lots of chipset and sometimes they are not recognized properly and you must tell him what kind of chip you are using.
My “real” sound chip is the ALC660 from realtek and the solution for me was having a look at:

gas@gas-laptop:~$ zless /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz


scroll down until you find
Module snd-hda-intel
--------------------

Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8),
ATI SB450, SB600, RS600,
VIA VT8251/VT8237A,
SIS966, ULI M5461


and down again until you find
ALC861/660
3stack 3-jack
3stack-dig 3-jack with SPDIF I/O
6stack-dig 6-jack with SPDIF I/O
3stack-660 3-jack (for ALC660)
uniwill-m31 Uniwill M31 laptop
auto auto-config reading BIOS (default)

as you can see the default config for those chips is “auto” and thats bad….for me the right one was 3stack-660.

Last step and we are done:
gas@gas-laptop:~$ sudo nano /etc/modprobe.d/alsa-base


and add as the last line the following:
options snd-hda-intel model=3stack-660

now, just because we mostly all come from windows,reboot.

Have fun hearing

Ci sono in giro un sacco di howto complicati (sopratutti quelli che parlano di “Perfetct Setup”) su come creare un server mail in debian / ubuntu ma ce ne sono pochi per quelli come me che hanno la semplice esigenza di voler leggere le email generate dal sistema allo stesso modo di come leggono le email mandate dagli amici.In pratica la mia esigenza è quella di reindirizzare tutte le mail di sistema su una casella email esterna tipo mionome@gmail.com.
