[TRIVIA] Come ci è finita lì?!

[lennynero]

Stavo cercando un modo per effettuare l'automount del mio smartphone su Slackware, ma ho incontrato non pochi problemi. La memoria interna del terminale è accessibile solo utilizzando i protocolli PTP(per accedere ai soli file multimediali), e MTP. Quest'ultimo non è propriamente semplicissimo da gestire su Linux(almeno per me), allora usanto gli mtp-tools e dando il comando mtp-detect ho ottenuto una cosa singolare:

Codice: Seleziona tutto

Device info:
   Manufacturer: samsung
   Model: Galaxy Nexus
   Device version: 1.0
   Serial number: 0149943E16011006
   Vendor extension ID: 0x00000006
   Vendor extension description: microsoft.com: 1.0; android.com: 1.0;
   Detected object size: 64 bits
   Extensions:
        microsoft.com: 1.0
        android.com: 1.0

Allora mi sono chiesto: "ma come ci è finita lì?!"

Comunque, a parte il contesto strano in cui si può incontrare Microsoft, qualcuno è riuscito a montarlo, magari con il tool go-mtpfs in automatico? Io sto provando con udev a fargli eseguire il mounting da utente(per poterci accedere anche da xfce...), ma non va. Qualche dritta?

Microsoft estorce ingenti somme sui brevetti software ai produttori di android. Pare che guadagnasse di più, per cellulare(!!!!!), dai brevetti su android che dalle licenze del proprio sistema operativo WP7. I ricavi ottenuti dalle estors... ehm dai brevetti licenziati ad android sono inclusi nel bilancio della divisione Entertainment & Devices, quella della Xbox, per mascherarne i buchi.

Accidenti, anche gli android ora vanno in questa direzione? Ricordo che avevo un lettore MP3 (sempre della samsung) che mi ha fatto penare non poco per gestirlo. Alla fine con Gnomad2 si lavorava abbastanza bene.

Datti una lettura di questa wiki, soprattutto la parte relativa a go-mtpfs, visto che dice:

The following has been tested on a Samsung Galaxy Nexus GSM.

L'idea, comunque, dovrebbe essere quella di poter montare un MTP come un FS normale grazie a fuse...però mi sembra che ancora non ci siamo.

Datti una lettura di questa wiki, soprattutto la parte relativa a go-mtpfs

Sono partito proprio da quel sistema, che secondo me funziona già bene, infatti riesco a montare il mio Galaxy Nexus(appunto). Il problema reale sta nel fatto che non riesco ad automatizzare la cosa. Spulciando un pò udev ho scoperto che è possibile eseguire comandi definendoli in una rule, tipo così:

Codice: Seleziona tutto

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="685c", MODE="0666", ACTION=="add", KERNEL=="2-1.1" DRIVER=="usb", RUN+="su -l $user -c /usr/local/bin/go-mtpfs /mnt/galaxynexus"

...ma la cosa non funziona. Per indagare gli attributi, il kernel ecc ho usato il comando:

Codice: Seleziona tutto

udevadm info -a -p /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1

Dimenticavo di dire che nel file fstab ho aggiunto anche la voce(ma forse non serve neanche):

Codice: Seleziona tutto

mtpfs      /mnt/galaxynexus   fuse      users,auto,allow_other      0      0

Alla fine come detto il problema attualmente è solo l'automazione...

@brg sapevo la faccenda dei brevetti, ma non vedo come possa Averla scovata in un trace della memoria interna:D, assurdo.

Riguardo Microsoft, non c'è nulla di cui stupirsi dato che questo indispensabile protocollo se lo sono inventato loro.
Io riesco a montare senza problemi il mio lettore Creative ZEN utilizzando mtpfs (c'è lo SlackBuild su SBo). Ho pure aggiunto la seguente riga in /etc/fstab per montarlo con un semplice mount:

Codice: Seleziona tutto

mtpfs            /media/mtp       fuse        defaults,users,noauto   0   0

[targzeta]

Infatti, lennynero, è inutile stare a modificare udev. Se riesci a montare bene il tuo device, vai semplicemente di mount/umount .

Quindi l'mtpfs funziona bene...bene bene...bene a sapersi ,

Quindi l'mtpfs funziona bene...bene bene...

Per niente bene.... Uso go-mtpfs innanzitutto perchè funziona bene, e per bene intendo che mi permette di scrivere sulla memoria interna dello smartphone, cosa che mtpfs non mi permette di fare. Con mtpfs posso leggere e cancellare, ma non scrivere(lo so è strano, ma è così). Inoltre sembra che le performance di go-mtpfs siano migliori...direi decenti. Ripeto il mio dubbio: la sintassi che ho usato è corretta(a meno del corretto matching dei vari flags...)? Come si fa ad eseguire un comando con udev?

[targzeta]

Secondo me la strade del mount automatico via udev non è quella giusta. Poi chi te la "smonta" "$user" chi dovrebbe essere? Ricorda che udevd gira in un suo ambiente, non sa nulla di collega il device al PC.

Per debuggure udev devi guardare il man di udevadm, vedrai che ti illuminerà.

Emanuele

[lennynero]

Allora faccio un attimo il punto della situazione: usando udevd --debug ho verificato che la sintassi per il riconoscimento del device è corretta(mannaggia a me che non ci avevo pensato prima), il problema risiede sostanzialmente nel comando. Per semplificare il comando ho deciso di sostituirlo con ".../go-mtpfs mountpoint", ma il log di udev mi restituisce questo:

[10937.575266] [10642] udev_event_spawn: starting '/usr/local/bin/go-mtpfs /mnt/galaxynexus'
[10937.580982] [10641] spawn_read: '/usr/local/bin/go-mtpfs /mnt/galaxynexus'(err) '2012/10/10 01:45:25 Could not find fusermount binary: %vexec: "fusermount": executable file not found in $PATH'
[10937.581255] [10641] spawn_wait: '/usr/local/bin/go-mtpfs /mnt/galaxynexus' [10642] exit with return code 1

L'errore mi è abbastanza chiaro, solo che ora non so come far trovare fusermount(da cui probabilmente dipende go-mtpfs) a udev. Suggerimenti?

[targzeta]

Nella regola, mettici anche:

Codice: Seleziona tutto

ENV{PATH}="dir_di_fusermount"

così il comando che è in RUN si becca la variabile d'ambiente PATH.

Questo era quello che mi serviva per far vedere a udev il comando fusermount presente in /bin, grazie mille. Ora ho un altro(forse l'ultimo) problema: Il ruolo. Se eseguo "go-mtpfs mountpoint &"(udev pretende che vada in background...) vedo il contenuto del drive solo da root.
Ora sto cercando di capire come fare per garantire i permessi rwx a other(GROUP e OWNER sembrano non sortire effetti nella regola di udev...); alternativamente sto provando ad eseguire il comando come normaluser, ma non vuole digerire la sintassi:

Codice: Seleziona tutto

su -l lenny -c 'go-mtpfs mountpoint' &

p.s. il comando si trova all'interno di uno script bash posizionato in /lib/udev

[targzeta]

Non puoi agire a livello di fstab? Non ci sono delle opzioni da settare al "montaggio".

Emanuele

[darkstaring]

Anche io ho lo stesso problema,
ma non riesco ad accedere per niente al device...
Ho installato libmtp-1.1.5 & mtpfs-1.1 e scritto in udev/rules.d/51-android.rules i dati del mio dispositivo

Codice: Seleziona tutto

root@:rules.d$ cat 51-android.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="1004", ATTR{idProduct}=="61f9", MODE="0666", GROUP="plugdev"


ma non saprei come configurare fuse e come posso montare il dispositivo

Se può servire questo è il log di mtp-detect

Codice: Seleziona tutto

mtp-detect

Qualche dritta?

Anche io ho lo stesso problema

Non mi è chiaro cosa intendi con questa frase, comunque il mio problema in sintesi è che mtpfs è "leggermente incompatibile" con la memoria interna del mio smartphone(Galaxy Nexus), ma leggendo le product info che hai postato deduco che tu hai il tab v909 g-slate, quindi ti consiglierei di verificare prima la compatibilità con mtpfs.
Per usare mtpfs, come suggeriva 414N, ti basta aggiungere in /etc/fstab la stringa:

Codice: Seleziona tutto

mtpfs            /media/mtp       fuse        defaults,users,noauto   0   0

successivamente ti basterà collegare il dispositivo e eseguire il comando:

Codice: Seleziona tutto

mount /media/mtp

probabilmente non ti serve neanche la regola di udev...
