So I've really grown to like having my local SMB shares from my media server mounted to my Xoom so that I can stream video and/or music or whatever on the fly. I don't like the mountpoints getting all messed up when I leave the network though, and I had less than stellar experiences with both Mount Manager and CIFSManager.
CIFSManager worked, but didn't integrate with Tasker, so I couldn't automate it. Mount Manager (the paid version anyway) came with a Tasker plugin, but I don't think it was fully compatible with the Honeycomb OS and I had a lot of issues with it (called the developer and left a message a few hours after buying it, hopefully I can get a refund for my $2.99).
Then I found the (free!) Locale Execute plugin and decided to just script the behavior I wanted myself. If you have Tasker and local SMB shares as well this could be a good solution for you. Just install the Locale Execute plugin from the market and follow these instructions. I'll post them here because I can't post to the dev section yet, and I'm not really sure if this is dev worthy anyway.
First I setup a profile for my home WiFi network (WiFi Connected > SSID [my home WiFi SSID]. Then I added an Enter action with the Execute plugin:
Code:
@!sh /[path]/[to]/[chk_and_mnt_script]/cifs_chk_and_mnt.sh
But I needed to make sure the mount points are cleaned if I disconnect for any reason so I added an Exit action with the Execute plugin as well:
Code:
@!sh /[path]/[to]/[umnt_script]/cifs_umount.sh
In Execute the "@" symbol is used to keep the program from echoing commands to "toasts" (the little black notification boxes you get sometimes, like when an app is "granted SuperUser permissions") and the "!" symbol is used to grant the line of Execute code root access.
I removed the toasts but I still wanted some notification as to what was going on and a quick google revealed this xda post: http://forum.xda-developers.com/showthread.php?t=773232
In that post I found a little .apk that would allow me to call a toast from a bash script. I've attached it to this post.
In the mount script I run a little check to find out if the "cifs.ko" kernel module is already loaded. If it is I skip that block, but if not I go ahead and load it. This way I always know that the kernel module is available before I try to mount the SMB shares.
Here's the Enter bash script I wrote called "cifs_chk_and_mnt.sh":
Code:
#!/bin/bash
lsmod | grep -q 'cifs' #check if cifs module is loaded
if [[ $? -eq 1 ]] #if not
then
am start -a android.intent.action.MAIN -e message 'cifs.ko kernel module not yet loaded. Loading now...' -n com.rja.utility/.ShowToast #displays toast
insmod /system/lib/modules/cifs.ko #loads kernel module
fi
am start -a android.intent.action.MAIN -e message 'Mounting local SMB network shares...' -n com.rja.utility/.ShowToast #displays toast
mount -o username=[windows login],password=[your password] -t cifs //[host ip]/[share] /[path]/[to]/[mount]/[point] #actually mounts share
#replace "[]" info with your own with NO "[]" and copy and paste line for as many shares as you want to mount
And here's the Exit script called "cifs_umount.sh":
Code:
#!/bin/bash
am start -a android.intent.action.MAIN -e message 'Home network lost. Clearing local SMB share mount points...' -n com.rja.utility/.ShowToast #displays toast
umount /[path]/[to]/[mount]/[point]
#replace "[]" info with your own with NO "[]" and copy and paste line for as many shares as you have mounted in the Enter script
Now, like I said, I used the linked (and attached) .apk to display toasts from the BASH scripts, but if you don't want it or care enough to use it then feel free to delete the toast lines or throw a "#" in front of them. If you do want the toasts displayed then you'll have to download it and install it. It won't show in your app drawer.
Anyway, here are the files (I had to add a ".txt" extension to the .sh files to comply with xda's attachment rules, but you can just rename them):
Thanks for this, looks great! I literally just paid for one of the premium smb apps only to find it didn't do quite what I wanted. I'm sure this will be what I'm looking for, cheers.
Edit:
Something for users to note: The umount script wasn't working for me, after some investigation it turns out that though when mounting, '/sdcard/dir' is acceptable, though the mount command actually considers my sdcard to actually be at '/mnt/sdcard' , so *that* was the dir I had to use when unmounting afterwards. This may be true for others too. I am using CM7 on a Desire.
Looking into this, I found that on my CM7 Desire, mounting the shares worked even if "lsmod | grep cifs" returns nothing, and the file is not in the place mentioned in your script either. To streamline the whole process, I just removed all the complicated stuff from the script and ran the mount command directly, saving time. Just a heads up for others, try it and see if it works for you.
Thanks so much for this!
Unfortunately, I have a couple of problems... When the share mounts, it is not in utf-8 format, so folders with odd characters do not show, even though I have that preference set in Mount Manager!
In addition, the unmount script does not work for some reason. When disabling wifi, I recieve a toast that Tasker got the message and executed my exit task, but there is no toast for the unmount script. I've triple checked for grammatical or directory errors, but there are none. Any idea why the unmount script isn't working?

To be honest, I completely forgot I ever wrote this. Still, the unmount issue could be due to your busybox version. Have you tried executing the relevant commands at a root enabled terminal? Do they work there?
Moreover, you should understand that I apparently wrote this to be completely independent of "Mount Manager" or any related app and these scripts are dependent only on: busybox, Tasker, and the Execute plugin.

I tried executing from terminal and the mount script works fine, but the unmount does not work. It gives me a "no closing quote" error. I'm pretty noobish when it comes to scripts, but it doesn't look like there are errors in the script itself...
Also, if it is independent of Mount Manager, is there a way to include utf-8 formatting in the script?

I dont care this post is 5 years old, i dont care that i'm bumping this thread...this little gold brick of information was FINALLY what i needed to figure out how to mount cifs without that "never-gonna-be-updated-ever-ever-again-cifsmanager" apk. I just threw the same basic code into tasker and finally got a mount. thank you! if i was more secure in my manhood, i just might embarrass myself.
the real reason for the bump, instead of mere word wasting, is to help anyone anyone searching for the cifs manager apk, or getting the error "no such device" when trying to mount. The issue is connected to the both the "mount name space separation" in SUPERSU, the old android sdcard permissions and who knows what else.
heres' the code I put into tasker:
su --mount-master -c busybox mount -o username=[USERNAME],password=[PASSWORD],rw,file_mode=0777,dir_mode=0777,iocharset=utf8,context=ubject_r:rootfs:s0 -t cifs //192.168.xxx.xxx/cifsync /sdcard/cifsync
no brackets of course.
that popped it right online, no issues but my kernel provides cifs.io support through synapse settings app. so it was easy to load the module at startup

Hey everybody. I'm on windows and adb's shell just keeps on pissing me off. Mainly, how pressing tab actually inserts a tab rather than tab completion . I'd really like to do something about this.
Here's a list of the things i've tried to get rid of this super-annoying behaviour.
-rolled a cross-compiler toolchain (glibc-based) for my phone (HTC Magic) and cross-compiled bash (in a vm). I actually made this work even with dynamic linking, and can start bash from within an instance of "adb shell". Unfortunatly, this doesn't change the tab behaviour, which appears to be baked into adb rather than a problem with the default shell.
-I thought i'd try something fancy by doing...
adb shell mkfifo /fifo
adb shell "bash > /fifo < fifo 2> /fifo"
adb forward tcp:9001 dev:/fifo
and starting putty in raw mode, connecting to localhost:9001. Unfortunatly, all is what happens is i get an echo of what i type and if i press enter a few times putty spits out ": command not found". I can't see why this shouldn't work but I suspect i'm Doing It Wrong.
-Searching the forum revealed puttycyg, which is actually really handy but unfortunatly suffers from the same tab completion problem as using adb shell in cmd.exe
How do you guys do it? Am I onto something with the adb forward thing? If so, how do I make that work?
I have also compiled bash but I have tab completion though adb. I do however use Linux as my desktop OS and am connecting through Konsole. So you could just try to install KDE for Windows. I know that I've looked for good terminal applications for windows but found none. They're all **** compared to what's available on nix.
This is my simple bashrc:
Code:
# If interactive do nothing.
[ -z "$PS1" ] && return
export HOME="/sdcard/"
PS1='[email protected]\h:\w\$ '
Also it's full of aliases for busybox. By replacing built in ls and similar you even get nice colors But still no line editing for some reason. I figure I might just need a proper libreadline or similar for that.
If anybody's interested in how I got this working, i cross-compiled socat for the droid. Required configuring with --disable-termios and manually editing config.h to set the #define for CRDLY_SHIFT and a couple other *_SHIFT macros to some values i found in Config/linux-2.6.24.h (or something similar, posting from memory here)
Once socat is on the phone, I made it pipe data from a bash shell to a unix socket it is listening on:
socat unix-listen:/dev/adbsock,fork exec:"/bin/bash -li",pty,stderr,setsid,sigint
(command shamelessly copied from http://superuser.com/questions/123790/socat-and-rich-terminals-with-ctrlc-ctrlz-ctrld-propagation ).
Then, on the pc i run adb forward tcp:9001 localfilesystem:/tmp/adbsock
And if i connect putty to localhost:9001 in raw mode (disabling line editing and local echo) I get a fairly complete bash shell that you can not only use tab completion on but even vi works
Again, posting from memory here so if anyone wants to try this and is running into problems i can dig it up from my ~/.bash_history.
Any chance you can post your socat port?
The tab completion thing is driving me insane! I don't understand why the ADB shell in *nix is proper, but the windows version sucks so much hairy donkey balls.
I've been using Ansicon so I at least get color in my shell, but ADB still mangles tab, and I don't even want to talk about what it does to Nano. Ugh!
Oh wow, this takes me back. I don't even have my android phone anymore (cancelled the contract due to terribly crap network service, and (unfortunately) the iPhone was the best phone in its price range from my new carrier).
So I don't have any files to give to you...
But, from what I can remember, to make it work, I built a cross binutils and gcc loosely following the instructions from the LFS book, compiled glibc + a few other libs socat wanted with it, and then socat itself, and then bash. I then copied the cross libc.so.6, ld-linux.so.2 (or whatever it's called on ARM) and all the libs socat wanted to /lib on the phone, and the socat and bash binaries to /bin. It's convenient that android keeps its important stuff in /system because it means you can avoid screwing around with your toolchain to make it look for a dynamic linker in some location other than /lib.
From memory socat was the only thing I had problems compiling, and thankfully I've already posted roughly what i had to do to it to make it build (because there's no way I remember lol)
Sorry I can't be more helpful!
How i got it working..
You may've seen me nagging around the forums for a sense-ui 2.2 rom with the cifs module in it. It looked like only the non-HTC roms have this module currently, that is, roms with a non-HTC custom compiled kernel.
This got me curious as to why, since people have compiled ext4 and tun modules for it just fine, they're in plenty of HTC kernel based roms.
So i got a cross-compile toolkit last night, and went looking for the closest kernel source i could find, and that turned out to be the msm branch of 2.6.32.9. I haven't even compiled a linux kernel in about 2 years, the last time i worked on kernel code was about 4 years ago, and i've never tried to make a module for a kernel that i don't have the source for. Meaning i got caught out with magic differences due to localversion appends etc, but eventually i built a cifs.ko that'd insmod.
I imagine that's how people made their ext4 and tuns (vpn) modules for the HTC built 2.6.32.15 too. So why no cifs module floating around for it already? Inserting the module fails with missing symbol errors for slow_work functions.
A patch was added after 2.6.31 called slow_work, that essentially stops certain filesystem activities blocking excessively. If you enable cifs in 2.6.32, even as a module, it requires slow_work to be enabled on your kernel. Likewise if you don't enable CIFS then slow_work isn't built into your kernel. Curiously the only two filesystems are cifs and gfs2 that require a slow_work enabled kernel.
HTC made the kernel, they didn't include cifs, it doesn't have slow_work enabled, so you can't fudge a module for it. Well, unless you edit out the slow_work code from the cifs filesystem in 2.6.32. As luck would have it, slow_work provided additional functionality, but didn't replace any.
So i edited out the slow_work code from the cifs headers and source files. Get the module for HTC's 2.6.32.15 below.
Edit: Changed the source from android git 2.6.32.9 to HTC's 2.6.32.15. Updated to remove debug symbols and tidied up the oplock code just in case anyone is writing many files to heavy traffic shared drives. UTF8 module included now also for non-ASCII filenames. Full credit to snq- for the tip on debug symbol stripping, the idea of including unicode support, and making me consider people might use this for writes on busy shares.
http://rapidshare.com/files/413103029/cifs.zip
For anyone interested i cross-compiled this using Sourcery G++ Lite 2010q1-188 for ARM EABI on ubuntu x86 installed to a virtualbox VM, with the 2.6.32.15 kernel source from the HTC incredible.
What's so good about CIFS anyway?
Support for CIFS lets you log into windows network shares from a linux OS and mount them as part of the linux filesystem. How's that any different to the SMB aware file managers like Astro or estrong file explorer? Transparent file streaming.
With a software client you can list and copy files from your windows share to your phone. If you instead mount the windows share into your filesystem, you can use files that're on the server as if they're already on the phone.
For example i'm connected to my home network right now over wifi and just opened a 700MB avi file instantly, as if it were already on my sdcard, instead of waiting 5-10 minutes for it to copy over usb, or half the movie's actual duration for it to copy over wifi.
Combine it with VPN and that's like having your entire movie/music collection on your phone anywhere you can get a broadband connection. No copying, no waiting, no ugly transcoding or streaming media servers, just use the files as if you already put them on the SD card.
The only real limiting factor is when the file's encoded bitrate exceeds your connection bitrate, eg. playing a 320kbit mp3 on a 200kbit EDGE connection.
How do i use this CIFS module?
You need a rooted phone with the official OTA 2.6.32.15 kernel, and possibly busybox too (for a mount binary with cifs support).
Quick and ugly instructions are to download the file above, copy it somewhere on your phone, eg. /sdcard/cifs.ko, and do the following as su in a terminal...
Code:
mkdir /sdcard/share
insmod /sdcard/cifs.ko
busybox mount -t cifs //192.168.0.1/sharedfolder /sdcard/share -o username=user,password=pass
Replace //192.168.0.1/sharedfolder with your windows share server name or ip and the folder you wish to access. Replace user and pass with your username and password, naturally.

Note to ROM authors
Any rom authors using 2.6.32.15 who would like to include this module in their rom, you're quite welcome to. You don't need to credit me either, although it would be nice.
Nice work buddy, I will test this out when I get back home.
Nice! Thanks for the module!
FYI: HTC just released the HTC EVO 4G - MR release - 2.6.32 kernel source and
Droid Incredible by HTC (Verizon) - MR release - 2.6.32 kernel source code.
It's working flawlessly!! Thanks you very much for this. And as you looks skilled, now pls try to find a way, how to connect bluetooth keyboard in Sense ROM and you are definitely my hero

Go to software information on the phone, is your kernel listed as Linux-2.6.32.15-gf9c0527? This module is built for the specific HTC OTA build of the 2.6.32.15 kernel only.

It's pretty much impossible to get bluetooth keyboards working on the HTC kernel without it's source code, since it'd require a full kernel recompile to enable it. Although the current HTC kernel has bluetooth HID support enabled, it doesn't have keyboard support enabled in the input devices section. Keyboard support can't be built as a module, only built into a kernel. Sorry!
If anyone is using gscript to automate their cifs mount/umount, i made up a little script to toggle the mount, for use as a gscript homescreen shortcut.
Code:
if test -f /sdcard/sharefolder/mounted.txt
then
busybox umount /sdcard/sharefolder
else
insmod /path/to/cifs.ko
busybox mount -t cifs //192.168.0.2/sharename /sdcard/sharefolder -o username=user,password=pass
fi
busybox df -h
Create a file called mounted.txt in the root of your shared drive, this is used to detect if the share is currently mounted.
replace /sdcard/sharefolder with the name of the directory you're mounting the share on.
replace /path/to/cifs.ko with your path to the cifs.ko module.
replace //192.168.0.2/sharename with your server ip and share name.
replace user and pass with your username and password.
Lastly the df -h is there for visual confirmation whether the share is mounted or not, it'll always be the last line of df -h when it's mounted, the bottom of the gscript window.
Thanks Myshkinbob,
It works
Just one problem.
I add my music as a share, I can play all songs but just a song at a time cannot have a playlist.
Is a way to do this with the default music player? or do I need another player?
Once more thanks Myshkinbob for this.

I had the same error connecting to one computer, if you try to connect using estrongs file manager (free version), that will fail also? Switch estrongs to LAN, hit menu, click new, click scan, then select the PC you're trying to get cifs to connect to. I wouldn't use Astro SMB, it seems a little buggy in 2.2, for me at least.
Just to elaborate, i did all my testing on my desktop pc, windows 7 ultimate x64, and that connected fine. When it came to connecting to my media center pc, windows 7 ultimate x86, i got the same memory allocation error you're seeing.
Estrongs file manager failed to connect also, so i knew it wasn't a cifs module bug. Both machines are on the same network, same firewall settings, it was a real puzzle why the desktop was reachable, and the media pc wasn't.
Does your computer have a long name by any chance? It's a bit bizarre, but my desktop has a very short name, bob-pc, and my mediacenter had a long name, mediacenter-pc. I changed the mediacenter-pc name to media-pc which then required a reboot, and restarted my desire to clear the DNS cache. When i tried now, estrongs file manager could connect, and my cifs mount no longer gave a memory allocation error.
So i'd try pinging 192.168.1.5 from your phone first, then check sharing settings on the pc and that your firewall considers the phone trusted or in a trusted ip range, then if that's all good, try giving the computer a shorter name if it has a long one, and rebooting everything.
I'd recommend you do the connectivity testing with estrongs file manager's LAN - menu - New - Scan, since it rules out any serious user error such as typos in the mount command or mounting to a non-existent directory.

I tried connecting to my other PC last night, and it worked fine, so its a problem with my PC.. I fiddled with my sharing settings so many times that I must have screwed up something in the process sometime.
I'm at work now so I'll do those tests when I get home, but I'm positive it'll work
Great work, really useful for streaming music and video. Maybe I'll create an application to make it easier to mount and unmount during the weekend. It would be really nice to see this module implemented on ROMs, and custom kernels.
Btw, any point in unloading the module? (to conserve battery or any other reason?).
unloading the module i don't think so....but i think that unmounting the share is going to save resources....not sure though
Oh one thing i can think of, disabling media sharing might fix it too. My media center has several accounts on it, all providing an individual share for the accounts media, i got rid of those at some point.
I'm not sure that using modprobe -r to remove the module would make any difference to battery usage, since unless you're actively browsing a cifs mount, the module isn't doing any work. It's probably best to unmount when you're done with your share tho, since i'm not sure how well cifs behaves when the network connection isn't available to a mounted share. It might just keep re-enabling wifi to get access to it.
I've since come across a nasty issue btw, video streaming is fine since it keeps the screen alive, but music streaming has a huge problem; when the screen turns off, the phone drops into sleep mode, and the wifi chipset drops down to keep-alive low power mode.
This destroys wifi bandwidth, a typical VBR 160kbps mp3 stutters like mad, so i'm guessing it leaves wifi at around 60kbps, certainly sub-100kbps.
There are 3 solutions i know of...
1) leave the usb cable plugged into either the charger or the computer, the trickle charge from a usb connection allows the wifi chipset to stay out of low power mode when the screen is in standby.
2) an app called WiFi Fixer, that was made for the nexus one. It was made to prevent wifi dropping completely during sleep mode, which isn't my problem exactly. However, in the options menu there's an advanced option called standby fix 2, or words to that effect, and it's meant to prevent the wifi chipset going to sleep. It's kind of buggy, and so far as i can tell it works by disabling/re-enabling wifi once the phone is in standby, to wake the wifi chipset out of low power mode. Like i said tho, it's far from perfect, and if you're using something like msn talk at the same time, you'll lose your connection to it while it switches wifi on and off.
3) Tinker with the broadcom wifi kernel driver. I -think- this is a module so it might be possible to remove low-power mode from it with the HTC kernel. Certainly this fix is used in some of the custom built kernels available.
I went with option 3, just hacked up the bcm4329 wifi kernel module to prevent it entering full standby mode.
mp3 streaming seems to work okay with the screen turned off now, just going to find some 320kbit to test it properly, or dare i say, some FLAC encodings.
Edit:
Just used http://www.appbrain.com/app/net.avs234 to test and even the mighty FLAC plays cleanly in standby over wifi now. Result!

How i got it working..
You may've seen me nagging around the forums for a sense-ui 2.2 rom with the cifs module in it. It looked like only the non-HTC roms have this module currently, that is, roms with a non-HTC custom compiled kernel.
This got me curious as to why, since people have compiled ext4 and tun modules for it just fine, they're in plenty of HTC kernel based roms.
So i got a cross-compile toolkit last night, and went looking for the closest kernel source i could find, and that turned out to be the msm branch of 2.6.32.9. I haven't even compiled a linux kernel in about 2 years, the last time i worked on kernel code was about 4 years ago, and i've never tried to make a module for a kernel that i don't have the source for. Meaning i got caught out with magic differences due to localversion appends etc, but eventually i built a cifs.ko that'd insmod.
I imagine that's how people made their ext4 and tuns (vpn) modules for the HTC built 2.6.32.15 too. So why no cifs module floating around for it already? Inserting the module fails with missing symbol errors for slow_work functions.
A patch was added after 2.6.31 called slow_work, that essentially stops certain filesystem activities blocking excessively. If you enable cifs in 2.6.32, even as a module, it requires slow_work to be enabled on your kernel. Likewise if you don't enable CIFS then slow_work isn't built into your kernel. Curiously the only two filesystems are cifs and gfs2 that require a slow_work enabled kernel.
HTC made the kernel, they didn't include cifs, it doesn't have slow_work enabled, so you can't fudge a module for it. Well, unless you edit out the slow_work code from the cifs filesystem in 2.6.32. As luck would have it, slow_work provided additional functionality, but didn't replace any.
So i edited out the slow_work code from the cifs headers and source files. Get the module for HTC's 2.6.32.15 below.
http://rapidshare.com/files/412285213/cifs.zip
For anyone interested i cross-compiled this using Sourcery G++ Lite 2010q1-188 for ARM EABI on ubuntu x86 installed to a virtualbox VM, with the kernel source taken from the android kernel git.
What's so good about CIFS anyway?
Support for CIFS lets you log into windows network shares from a linux OS and mount them as part of the linux filesystem. How's that any different to the SMB aware file managers like Astro or estrong file explorer? Transparent file streaming.
With a software client you can list and copy files from your windows share to your phone. If you instead mount the windows share into your filesystem, you can use files that're on the server as if they're already on the phone.
For example i'm connected to my home network right now over wifi and just opened a 700MB avi file instantly, as if it were already on my sdcard, instead of waiting 5-10 minutes for it to copy over usb, or half the movie's actual duration for it to copy over wifi.
Combine it with VPN and that's like having your entire movie/music collection on your phone anywhere you can get a broadband connection. No copying, no waiting, no ugly transcoding or streaming media servers, just use the files as if you already put them on the SD card.
The only real limiting factor is when the file's encoded bitrate exceeds your connection bitrate, eg. playing a 320kbit mp3 on a 200kbit EDGE connection.
How do i use this CIFS module?
You need a rooted phone with the official OTA 2.6.32.15 kernel, and possibly busybox too (for a mount binary with cifs support).
Quick and ugly instructions are to download the file above, copy it somewhere on your phone, eg. /sdcard/cifs.ko, and do the following as su in a terminal...
Code:
mkdir /sdcard/share
insmod /sdcard/cifs.ko
busybox mount -t cifs //192.168.0.1/sharedfolder /sdcard/share -o username=user,password=pass
Replace //192.168.0.1/sharedfolder with your windows share server name or ip and the folder you wish to access. Replace user and pass with your username and password, naturally.
For more detailed instructions on automating the mount and umount etc, there's an excellent thread here...

I get this occasionally, usually it's some background task that was using the share, such as a file explorer, music or movie player. Even though they weren't currently in the shared directory, they still prevented me unmounting. Killing all media/file explorer apps should let you unmount.
you seem to have compiled your module with debugging options, that's why it's size is about 3MB
you might want to strip debugging symbols and sections (just them) with arm-eabi-strip --strip-debug (or arm-none-eabi-stip in your case)

Hi,
I have looked around and cant seem to find an application quite fitting.
All I want is an app that will wirelessly sync just a folder automatically when I have my WiFi turned on, is there an app that can do this?
i.e. Come home from work, turn on wifi and it just syncs.
Many thanks
To any developers about: How hard would something like this be to make?
I think dropbox does that?
Dropbox syncs a folder on multiple devices with a folder on dropbox server.
There is also an app called PCFileSync that syncs a folder over wifi between the phone and a samba share. I am turning it on with Tasker once it connects to my home ssid. Works great!

samba share? hm........
rsync and ssh would be a much better choice and cleaner, just a script to run.

Tasker+Rsync, and combine it with a ssh key and you can automate it easy.
BTW, I decided to do this today.. I have one which backs up /sdcard/DCIM, and another which backs up the entire sdcard, both over wifi to my Fedora Linux workstation. I'll have to figure out how I want to execute these, but I can do it from GScript Lite, Tasker, whatever floats my boat.
Here's the notes I took, just in case I have to do it again in the future, hope it's useful to some folks..

Horrible user interface but once things are set up you need only to start the client on your phone and press the "Start Sync" button.
Supports multiple configuration sets (local/remote directory pairs, ip address, etc), each can be started separately.

I'm actually syncing to 2 android phones, with dropbox, rsync and dropbear.
Dropbox is good for documents and such, with small filesize and possiblity of sharing with others.
Using rsync for large files like movies and music folders, also some pictures, notes, keepass, and stuffs I like having around, things that's only going around between my laptop and phone.
Running a crontab that scans for my phone in adb devices, if found, pull a "last sync status" file, if interval > 1 hour or changes made locally, do a local notify-send till rsync is done, then execute dropbear on phone, rsync remote and local, kills dropbear, then push last sync file.
This way, no resources is wasted on the phone, all scanning and verification of device, system, and files were done on laptop.
At the same time I'm monitoring my development phone with frequent ssh rsync when it's in range, push updates, kernels and such across in proper folder structure.
This will ensure changes or new kernels were pushed to phone ready for testing.
Could use the same script for both phone, be it adb+ssh+rsync or pure ssh+rsync, but I personally don't like having sshd running in background when I'm connected to wifi hotspot.
Cleaner this way, less resources wasted on phone, and I can have full control over what, where, and when to sync.
I do realise that there isn't much choice for syncronization in the wild, thus you may like yo try something along the same idea, and you may get your own perfect combo to sync.
P.S. backing up, restoring or syncing bookmarks from browser.db and such could be done this way.
I have SSHFS working from a Debian chroot. I have a SGS2 (SGH-i777) with CyanogenMod 9 (2012-06-12 nightly), and everything is working as the root user. I can read the SSHFS mount and the files it contains. My problem is that a normal, non root user cannot read the SSHFS mount. The UID/GID of the mount is 1000/1000, which is the UID/GID of the user that owns the source of the mount (my primary workstation user).
I'm trying to use KeePassDroid to read my KeePass database in place, so any changes I make get immediately reflected in my master file, no need to replicate the file. If I could grant KeePassDroid sudo privileges, I think that would be good enough for me. But I'm stuck. I don't know enough about how users are managed on Android, and I don't know how to give superuser privileges to an arbitrary application (it doesn't appear that the Superuser app that shipped with my root ROM allows for that). Any ideas?
SSHFS... almost got it working... a little closer now....
I've finally gotten a chance to look at this further. It looks like sshfs (the mount utility) has the capability of using an arbitrary UID for the owner of the mount. So, I looked in /data/system/packages.list to determine the UID of the KeePassDroid application. Seems the UID for that app is 10079 on my system. But that doesn't work, because if I log into a shell as that user ("su - 10079"), the keepass directory doesn't even show up in an ls directory listing. I've also tried 10080, which is apparently the UID of the OpenIntents file browser used by KeePassDroid to select the KeePass database. It obviously didn't work.
My next try will be to set the entire chroot to be owned by the 10079 user. I'll post back here if I find success.
[SOLVED]SSFS... got it working...
I finally got it to work, had to pass the -o allow_other option to sshfs, and now my KeePassDroid app can read my database. Next task is to have it load the chroot and sundry stuff automatically, so I have access to my KeePass database wherever I'm at.
Hopefully this information will be useful to the next schmo who tries this. I can already see that this thread shows up on Google.
Thank you in advance if you can help with this, unfortunately I'm not going to be able to follow through with this very well at the moment. If this gets no attention I'll bump it when I can follow through.
I want to mount a smb/cifs share from my router to my Nexus 5.
I can successfully mount the share and view it in terminal but none of it shows up in any apps...and that's pretty much my issue.
Here's some unimportant info, and a little info about me, I'm as scatterbrained as they come. The reason I want to do this is to stream my movies on the "NAS" to my Chromecast through Allcast or something.
As of now I'm using an entware mini dlna package on the router to stream everything to Avia. My problem is dlna broadcasts all my media to my entire network...no password required or anything. Also accessing my files through Avia is a pain in the ass, navigating through the folders repetitively gets exhausting.
Here's what I've come up with so far:
I'm using hammerhead-faux123-010m kernel, and SlimRC3.
CIFS DebugData:
Code:
CIFS Version 1.78

Then I tried OneClick Mount app:
https://www.dropbox.com/sh/muabb9vp1i8ubxt/o78FSYMcHo
From what I can tell from the app logcat, the app tries to move the debuggered file, create its own with a chosen command inside, start then stop it, and restart the original.
I might try to do this manually later, as in a month from now at the least. I'm pretty sure a certain someone is pissed off at me for not becoming one with the universe n all that jazz.
I'm gonna leave a couple links here so I can delve into them later, they seem to have crazy amounts of useful information:
[HINT] How Stickmount (and others...) are working with Android 4.2
Debuggered script
Sincerely, Head is spinning
Sorry but as of android 4.4.2 CIFS at a device level (all accounts see the network shares) no longer works and no one has a solution. This includes rooted devices and custom Roms. Of course apps such as ES File Explorer can have network share accesses but not all apps can utilize that access. For example MX player can be invoked from an ES file folder by clicking on a video file but apps like PowerAmp cannot see those folders. Some apps include built in network share features but they have the same restrictions as I previously described.
Things all changed when Android included multiple accounts and security started to get tighter. Initially developers found ways around those measures but too my knowledge, with 4.4.2 no one has found a work around.

One workaround is hijack a system process such as debuggerd (debugger daemon) which runs with higher than su permissions. This method still works but is awkward to exploit manually. Apps such as foldermount use this workaround but not for network mounting, but it shows that it is still possible.
I have a Raspberry Pi running OpenELEC for streaming my locally stored media. I use my Chromecast for streaming Netflix, Google Play media, etc.
I understand what you are trying to do, but a dedicated device works great for me.
That said, you might keep an eye on VLC to see if they start supporting casting to Chromecast. That would likely accomplish what you are asking.

This is what I'm going to attempt next, from what I read it can be terribly inconsistent if not done through SSH, so that's a bummer. I just need to get more information on how to do it. Debuggered in general confuses me.

This is what I've been wanting to do with my old Galaxy Nexus. I have the HDMI adapter and everything but the screen is broke (the digitizer works), so I plug it into my TV and randomly hit the screen hoping to eventually connect my bluetooth mouse lol. No such luck. I wish I could just boot it into a custom build but that's never gonna happen. Unless OpenELEC works on android devices? Seems unlikely.
debuggerd can be replaced with a shell script with the mount command in it and it will run at boot.
It's really messy. I found I had to put the original debuggerd back or the phone would lock up.

I didn't understand the mount command he used so I used
Code:
/system/xbin/busybox mount -r -o noperm,rw,file_mode=777,dir_mode=777,uid=1023,gid=1023,unc=\\\\192.168.1.1\\NAS,username=***,password=*** -t cifs none /data/media/0/cifs
You also need to use /data/media/0/ otherwise it will only work in already opened apps apparently.
So thanks rootSU...And that should work, I'm going to do it in a way where I don't have to use scriptmanager but that's the gist. All the credit goes to the people in the threads I linked, I have absolutely no idea what I did here and I learned nothing.
Nothing special to see here. :good:
Here's a way to unmount it so it doesn't explode your apps when you disconnect WiFi:
/system/bin/debuggerd.binnn
Code:
#!/system/bin/sh
/system/bin/umount_movies.sh
exec /system/bin/debuggerd.bin "[email protected]"
/system/bin/umount_movies.sh
Code:
#!/system/bin/sh
/system/xbin/busybox umount /data/media/0/cifs
/system/xbin/busybox umount -r -o noperm,rw,file_mode=777,dir_mode=777,uid=1023,gid=1023,unc=\\\\192.168.1.1\\NAS,username=***,password=*** -t cifs none /data/media/0/cifs
Script_eject.sh
Code:
#!/system/bin/sh
mount -o rw,remount /system
sleep1
/system/xbin/busybox mv /system/bin/debuggerd /system/bin/debuggerd.binn
sleep 1
/system/xbin/busybox mv /system/bin/debuggerd.binnn /system/bin/debuggerd
sleep 1
mypid=$(/system/xbin/busybox ps -o pid,comm | /system/xbin/busybox grep 'debuggerd' | /system/xbin/busybox awk 'NR == 1 {print $1}')
/system/bin/kill $mypid
sleep 1
/system/xbin/busybox mv /system/bin/debuggerd /system/bin/debuggerd.binnn
sleep 1
/system/xbin/busybox mv /system/bin/debuggerd.binn /system/bin/debuggerd
sleep 1
mount -o ro,remount /system
I'm automating all this with Tasker.
Script task: (I have it run at boot)
waits 15 seconds
run shell command to kill debuggerd
wait 5 seconds
media action scan card /
Script_eject task: (I have it run when I disconnect from my SSID)
run shell command with the script_eject.sh code
wait 6 seconds
media scan card /
It has been seamless so far, also lol.

I'm on the latest Slim, with latest faux kernel. Faux has cifs modules built in, I'm not sure about Slim or Franco kernel. If you have a cifs folder in /proc/fs I assume that means the kernel has the cifs modules.
