If you got this error message in your Apache error log, you could check if the reason of this is that it folder on which the server is trying get access is readable by Apache user (www-data in Ubuntu by default). In order to test this condition, you could try:
work as root user
#su – www-data
if you get “can’t cd to yourDirectory” or similar is due that Apache user can’t access to the file or directory.
See error log from console:
#tail -f /var/log/apache2/error.log
Today, I found that my computer deson’t connect correctly to Internet, when I see the icons of network on Panel, this show “unmaneged” for wired connections, so, after see a post, I read that you must change the line from
on the file:
After it, I did reboot my pc.
Top command using ssh client
If you access to you ubuntu remotely using a vnc client, like VNC-Viewer on Windows or other, probably sometimes you have issues with you connection or you miss it. So how you can fix it? I access to ssh console using Putty.exe from Windows, then I check the process using the command:
then, you should look for your vnc-server process, in my case it’s called “vino-server”, and then press K (Kill) key and write the PID of the vino-server daemon and then press Enter twice to confirm. Ubuntu will re-start the service automatically, so you will able to connect again with you vnc-client.
Ahora en español…
Si te conectas a Ubuntu usando algún cliente de VNC, tal como VNC-Viewer, probablemente a veces tengas problemas de conexión y la pierdas, si esto ocurre, deberás acceder a tu computadora de una manera alternativa, por ejemplo, usando un cliente SSH, por ejemplo, desde Windows pueder usar Putty.exe. Una vez que lo descarges y accedes a Ubuntu, puedes ejecutar el comando
para listar los procesos en ejecución, buscar en el listado el servidor VNC, que por defecto en Ubuntu es “vino-server” y presionar la tecla K para matar el proceso. Ingresa PID correspondiente al proceso y presiona Enter dos veces para confirmar. Esto reiniciará el servidor VNC.
After a couple of unsuccessful attempts :(, I have Installed my laser printer in Ubuntu 8.04. And here I’ll show you the steps carried out to accomplish with this.
UPDATE TO THIS POST: I’ve Installed my printer in Ubuntu 8.10 but, for this release I made some changes that are commented ahead.
Download to HPLIP applications from HP Linux Imaging and printing web site, clicking in “Download the Automatic Installer”
After, execute installer running in console (into folder that you have the file)
Follow the instructions…
I selected automatic installation mode.
I confirmed my Linux distributions. Note: For Ubuntu 8.10 I selected “n” in order to indicate that version is not correct (despite it said the correct version). For details see next image
I entered my root password and so on….
To finish, the application will launch a Windows form..
- Select “USB..”
- Select you printer in the list show in “Select from Discovered Devices”
- Select recommended option in “Select/Confirm PPD File”
- and add details in “Enter Printer Information” such as pictured below. If see disable “Next” button, you should delete all field in form and add information again. I spent lot of time thinking what is the wrong field because, until you edit the field this will not show in red.
After a lot of attempts (edit files, up and down volume controls) I could enable sound in Ubuntu. To do this, I made the next:
- Re-install alsa-utils. I think that this is not necessary.
- Open volumen controls. (Alsa Mixer)
- Preferences, and check “Channel Mode”. This will visible a TAB “Options”, here you must select “6ch” and ready.
To test your surround system, you can write into Console:
speaker-test -Dplug:surround51 -c6 -l1 -twav
and this will allow listen a voice for every speaker.
root@konunantulinux:~# speaker-test -Dplug:surround51 -c6 -l1 -twav
Playback device is plug:surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
4 - Center
1 - Front Right
3 - Rear Right
2 - Rear Left
5 - LFE
Time per period = 8.449852
To know your sound card, you can write:
root@konunantulinux:~# sudo asoundconf list
Please note that you are attempting to run asoundconf as a privileged superuser, which may have unintended consequences.
Names of available sound cards:
In this case, VT82xx is my card.
My surround system is a Genius SW-5.1 100
Good Luck. :)
