hi,

I tried cifs manager but that only shows up in the current session (ES File manager but no other apps).

so, i stripped all the commands back to the point where i could get it to mount, then i started adding back and got it working ....

question: I am trying to write a script that cleans up and creates the mounts....

what command can i use to unmount the mount points. i tried umount <path> and this appears to work (as long as you su it) but then when i try to delete the folder i get "device busy" ... if i reboot and delete its fine but thats not the desired umount method!

so what I am looking for is a forcible unmount and delete of mount folder...

thanks

Dan.

Well that confirms you can mount cifs. The next step would be to try a manual mount via adb. 'adb shell' into your phone and do the mount there, see if you get the seg fault and if not if it shows up in apps.

As for unmounting, umount seems to work fine for me although I have never tried to delete the mount point afterwards. It's possible you have to umount from within adb if you mounted in adb. On a full Linux there is also 'umount -lf /mountpoint' (-l for lazy and -f for force) but I don't know if busybox supports that. It does seem to support moving a mount via the -o move option (i would assume the syntax is 'mount -o move /mnt/old /mnt/new' (untested). You could perhaps use that to just move it somewhere out of the way, then delete the folder.

I'm trying to make this work on a Nexus 7. I've got the modules and the script seems to load them and mount successfully. The mount point is empty, though.

Script Manager reports the following after connecting to localhost:5555 and "Mounting share via adb...":
Usage: adb services [-l] (I think that's a lowercase "L")

usage: setprop <key> <value>
Mounting success!

To get that far I had to edit the script to change ` to ' and to stop CIFS Manager from loading the modules at startup (was getting "insmod .... failed (file exists)" errors.

I realize this is a Nexus 10 thread, but surely the principles are the same.

Any advice? Thanks.

There is a typo in the script that causes the setprop message, I was going to fix it but forgot, it doesn't seem to matter other than popping up a warning.

As for the modules. you need ones for the kernel version of your device, specifically you need to match the g4e6298b at the end which is the Nexus 10 kernel. I believe the Nexus 7 uses 3.1.10-g22b4fcd. So are you using Nexus 7 cifs specific modules or ones you got from here? There are Nexus 7 ones here.

If you are using the correct modules, fire up a terminal and check the output of 'mount' to see if your mountpoint is listed and then check if you can see the mount contents in the terminal.

[SOLVED] Share is read only

So far I managed to get the adb script working, but the share is mounted as read only (permission denied when trying to mkdir). When connected by ES Explorer LAN using same credentials I can read/write, so no Windows/user permissions problem. I checked the local folder permissions and seem correct (chmod 777).

Is this a cifs module limitation? Do I have to add anything to the mount line to allow write permissions?

Thank you in advance.

EDIT: Solved. Just found that adding file_mode=0777,dir_mode=0777 to the mount code solves my problem. Full RW permissions achieved.

Thanks for the reply.

I'm on 4.2.1 and I am using those modules. The script still says "Mounting success!" but the mount command does not show my mount point. The script is supposed to return "Mounting failed..." if the grep doesn't see it, so I can only assume the mount point is returned at that point in the script.

Here's how I tested it: mount | grep myshare > /storage/emulated/0/mount.txt

The text file is empty.

A couple things:
1. even when I delete the mount point folder, I still get the "Mounting success!" message in the Script Manager window. How can that be?
2. if I use mount | grep data > /storage/emulated/0/mount.txt I get all the references to "data" from the grep in the text file.

I read that I might need a patched version of busybox. I don't think I have that. I have the free BusyBox 1.20.2 from the App Store. If I need the patched busybox, where can I get it?

here's the script:

Tried the script.

Getting numerous "not foundulated" for all lines that set a variable

EDIT: Turns out it is saying "not found" and tacking on the last part of "emulated"

Then it gets to the SERIAL

if [ "$SERIAL" = "" ] ; then

and it stops/fails. I tried to echo $SERIAL and it was empty.

I am betting this is due to the "not found" for variable sets.

Sorry for the noobishess, but what goes wrong?

$MOUNT_CMD
"

The quotes should be on the same line of $MOUNT_CMD

MrGrimace · Jan 7, 2013

Tried 1 lining all commands and removing comments. Destroys readability, but it cuts down the errors. sh still fails to set variables for some reason.

sh in this case is built in and is not a soft-link to busybox. But I tried the same script with ash which IS busybox and same issue. Gets to if statement and then says "if" not terminated or not matching pair (not in front of me at the moment)

What is strange is that nobody else seems to be having these issues and we are all on Nexus 10. I am rooted on Stock and installed BusyBox 12.0.2 and replaced the busybox binary as instructed.

Thank you for this modules, it's work perfectlly on a stock rom.
But I have a question, when i mount my cifs drive i can see file in all program but not in google music...
Anybody have a solution for see music file in google music ?

Thank's you in advance.

Google Music will be using the media scanner. So Android must scan your folder before it shows up. This is a pain as it will actually scan every folder on a mounted partition (unless you add a blank file named ".nomedia").

Probably a better idea to look at DAAP/UPnP or use the Google Music cloud sync feature.

After the update to 4.2.2 the loopback method to use the adb shell directly on the device isn't working anymore. A XDA-User allready filed a bug-report here: http://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=48126

Damn it, no mount anytime soon...

New modules for kernel 3.4.5-gaf9c307?

Hi H3g3m0n.

Last OTA 4.2.2 made more difficult to adb from localhost because key validation is needed even for loopback connections. I managed to get it working appending the public key generated by the loopback connection as they say in the page that Borbosch posted in #69.
Now I can ADB but I get the Exec format error when loading the modules. I guess that's because the kernel changed to 3.4.5-gaf9c307. I had no problems with 3.4.5-g4e6298b.
Could you please compile new modules for the new kernel version? I've been trying to find custom kernels with cifs enabled but didn't succeed. I know several roms out there have cifs enabled, but I'd rather use stock rom and modules / kernel patches.

Thank you in advance.

Question from new user

Hi,

I want to know if is it possible to do this with a Nexus 10 rooted with Android 4.2.2 and the original kernel?

Thanks in advance.

Regards,
Pablo.

jmtw000 · Mar 3, 2013

Hi Pmincz,

I don't have a nexus 10, so I can't say for certain, but I have gotten it to work on my rooted stock nexus 7. I don't see any reason why it wouldn't work on the 10. You can see how I did it on my 7 over at http://xdaforums.com/showthread.php?t=1781411&page=20 post #197 . The only difference should be, you'll need the modules for your device. I doubt the ones from my post would work as they're for the 7.

Since the 4.2.2 the modules provided in the OP are no longer valid

Is someone is able to compile a nls_utf8 module with the latest sotck kernel or CM10 kernel or any other kernel ?
I'm able to mount my cifs share, but my file are not well formatted due to UTF8 character ... i'm desesperate to not find any kernel with CIFS and UTF8

Exists any DL for new 4.2.2 compatible kernel modules?

You may try adding iocharset to the mount options. That's my code:

Code:

busybox mount -t cifs -o user=$USERNAME,password=$PASSWORD,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777 [...]

That worked for me. Network share is Windows. The rw and 077 modes allow file writing permission (check Windows share permissions before).

I have uploaded modules that should work with 4.2.2. I haven't tested them so let me know if there is any problems with insmod'ing them. The adb hack now requires an extra step to add an encryption key, check here. I'm also not sure if the patched busybox is needed (there has been a new release).

This parameter is only working if the kernel support UTF8 and/or have a NLS_UTF8 module loaded.

By the way, I've successfully compiler Franco Kernel with CIFS and NLS_UTF8 builtin, so I've fixed my issue.

Hey...

So what does this mean? You have a kernel that CIFS works "out of the box" without all the other fun stuff needed? Or is this just to eliminate needing to have the mod files referenced locally on your filesystem?

I can't believe it's been THIS long and we still don't have a more turnkey, easier solution than the OP.

Trinity Ten mounts CIFS shares without the need for additional modules. Been using it for a while.
