|
Ho un problemino da sempre che vorrei risolvere una volta per tutte...
La situazione e questa ... dati tre utenti: root, joe, gilles
quando avvio la mia linux box il primo che entra prende 'posesso' di certi devices (per esempio il /dev/dsp) rendendoli inutilizzabili ad altri.
Esempio pratico:
1. avvio gentoo
2. entro come gilles e faccio qualcosa
3. esco e rientro come joe e avvio kde
a questo punto per esempio kde mi avvisa che /dev/dsp e di proprieta di altri e non e utilizabile. se vado a vedere effettivamente e di gilles 
Come e' possibile che il primo che accede si becca come propietario tutti i devs 
Grazie per any consiglium  )
Joe

| Code: | # ls -al /dev/dsp
lr-xr-xr-x 1 root root 9 Sep 20 09:58 /dev/dsp -> sound/dsp
# ls -al /dev/sound/dsp
crw-rw---- 1 root audio 14, 3 Jan 1 1970 /dev/sound/dsp |
Così dovrebbero essere. L'utente non diventa proprietario di nulla, se è membro di 'audio' può accedere al device altrimenti no.

A me e' capitato una cosa simile con la webcam. Se entravo da root, attaccavo la webcam e provavo ad usarla /dev/video0 diventava di proprieta' dal primo che la usava.
Poi ho aggiunto il mio utente al gruppo 'video' e si e' sistemato tutto...
strana sta cosa... |

Sei sicuro di caricare i moduli alsa all'avvio della macchina? Li hai in autoload?

Controlla in /etc/security/console.perms. Dovresti avere una linea tipo:
| Code: | | <console> 0600 <sound> 0660 root.audio |

ahh ecco comque anche cambiandolo in 660 non cambia la situazinone....
E comunque pam nella gestione del devfs no dovrebbe aver a che fare visto che nell'/etc/devfsd.conf c'e' questa riga:
| Code: |
# Uncomment this to let PAM manage devfs
#REGISTER .* CFUNCTION /lib/security/pam_console_apply_devfsd.so pam_console_apply_single $devpath

Il concetto e':
1) non puoi avere un kernel monolitico con alsa in quanto alsa sono solo moduli (su 2.4);
2) se fosse che il kernel te li carica da solo e non in autoload, ad esempio lanciando il tuo WM, non vorrei che ti settasse i parametri male, invece di lasciar fare a autoload.

Foers enon riesco a spiegarmi ... il problema sta a monte dell'avvio del WM
Il cambio di owner avvien ancora a livello di console prima di interessare X
