SMB/CIFS/NFS Network Shares with CifsManager

---

Hello,

WARNING: Perform at your own risk. This won't brick your Nook Tablet

I've added NFS modules.

I've compiled cifs, nls_utf8, slow-work, and tun modules for CM7 Alpha. They're down in the attachment. Stock modules are also in the attachment.

If you have audio lag while streaming 720p/1080p, it's because of software encoding and didn't add CIFSMaxBufSize=130048 to option. I've tested videos in stock with hardware video decoding and there was no audio lag with HD movies. 1080p videos might have a few stutters. CM7 Alpha/Beta, in my test does not support H/W decoding yet.

I've been using cifs built in to the kernel for a while with CM7 beta, it's better than using modules. I've talked to Celtic, and Gonz will have cifs/tun built into the kernel in later release.

I've tested HW decoding in CM7 and both 720p/1080p struggled. CIFS transfer over wifi is slow and it's suggested that you use NFS.

*UPDATE in CM7: For 720p/1080p MP4 videos, streaming through ES File Explorer is perfectly fine. Through CIFS, the videos stutter. You can try to play around with options like rsize=130048,wsize=4096. 130048 (127x1024) is the max size.

HW Decoding is limited to 3GP, 3G2, MP4, M4V, MKV, WEBM, H.264 (Baseline/Main/High profile) up to 1920x1080, MPEG-4 Simple/Advanced Simple profile up to 1920x1080, & H.263

Description
Access your CIFS/NFS network shares with your Android device. (root needed)

Manage your cifs/nfs network shares on your Android device (root access needed). This little app allows you to conveniently mount/unmount your network accessible file resources and access your data transparently via your favourite Android app (playing music / videos, accessing documents etc.).

How to setup cifsmanager,
http://iamafanof.wordpress.com/2010/...h-cifsmanager/

In the settings,
path to cifs.ko -> /PATH/slow-work.ko:/PATH/cifs.ko:/PATH/nls_utf8.ko
change “PATH” to the location where you put your *.ko files. I'd recommend putting the modules on your sdcard root. It's much easier to enter the location.

When creating new share,
Options -> iocharset=utf8,directio,CIFSMaxBufSize=130048
*no spaces between comma

If you want your mount point to be on your sdcard,
Mount Point -> /sdcard/PATHNAME
change “PATHNAME” to your desired folder name.

I've attached tun.ko to the attachment. It load via insmod, but not tested.



For NFS modules, you can insmod them or use CIFSManager to load them.

By terminal insmod

Open up terminal

# su *give superuser access
# cd sdcard
# insmod exportfs.ko
# insmod sunrpc.ko
# insmod lockd.ko
# insmod auth_rpcgss.ko
# insmod rpcsec_gss_krb5.ko
# insmod nfs.ko

Alternatively using cifsmanager to load module

path to cifs.ko -> /sdcard/exportfs.ko:/sdcard/sunrpc.ko:/sdcard/lockd.ko:/sdcard/auth_rpcgss.ko:/sdcard/rpcsec_gss_krb5.ko:/sdcard/nfs.ko
change “PATH” to the location where you put your *.ko files. I'd recommend putting the modules on your sdcard root. It's much easier to enter the location.

I don't know if auth_rpcgss.ko and rpcsec_gss_krb5.ko are needed. I've never used NFS before. These modules loaded via insmod, but I can't test them.

-- specify the Share Path as <server>:<path> (e.g. 192.168.1.17:/mnt/Spajz)
-- Username and Password fields are ignored in this case

You can use terminal to mount NFS,
$ su
$ busybox mount -o nolock,ro,hard,intr,vers=3 -t nfs 192.x.x.x:/your/nfs/share /mnt/sdcard/share

How to compile modules (cifs.ko, slow-work.ko, nls_utf8.ko, and tun.ko).

I am assuming you know how to install tools and dependency packages for compiling kernel source.

My toochain path -> /HOME/arm-2010q1/

# You can add “-j(cpu+1)”, -j3 or –j5
> cp kernel/slow-work.* fs/cifs

# Change the following two lines of code in slow-work.c and save.

round_jiffies(jiffies + SLOW_WORK_CULL_TIMEOUT));

Thanks a ton for this!!! It works great.

However, I have trouble unmounting... Is there a trick to doing this? It says that it is unable to...

Also, how does the mounting work after your device goes to sleep? Does everything connect as it should?

Hey,

Un-mounting work when the file from the share is no longer access. If the file is still being used, it will not un-mount, so you have close the app you're using. I do have problem un-mounting when viewing image with PerfectViewer. For some reason the image is still being used even if you close the app but I've had that problem even with NC. To un-mount, just press menu and un-mount all or long press on the share you want to un-mount.

When your NT sleeps, the Wi-Fi get disabled. It will reconnect once Wi-Fi get reestablish.

Everything work, I can stream videos, books, images, apps, musics. etc..

Fantastic. I was able to get it to unmount after rebooting (after mounting again after boot). I must have had an app that was stubborn.

I'm surprised that more people aren't interested in this app. I guess they don't understand what they can do with it?

Omg I just realized about this, im interested in the tun.ko. module so I can set up a vpn ill test tomorrow. Can someone confirm is working?

Edit1: I confirm that the .ko files work with cifsmanager flawlesly , testing tun.ko now first with DroidVPN and OpenVPN after, will report back.
Edit2: tun.ko WORKS!!! woohoo, eather if i put it in /sdcard/modules/ or /system/lib/modules/ works and cifsmanager does the job loading all the .ko files via insmod . Tested with DroidVPN and im using Pandora right now.

Ok im all setup via LAN for stream my media succesfully but now i want to stream my media anywhere with a wireless connection (WAN).
I have been doing my research for 2 days and so far i have tried setting up a FTP filezilla server with a no-ip host ip on windows pc but it doesn't work neather with cifsmanager nor ES file explorer FTP tab, vpn is not a go for me because stream videos can be choppy, anyway what i want is to find a reliable way to do this at list for music and videos, i have been searching but all i find is how to do it "local" which i already have setup and running. So big question here is does anybody know a reliable way to reach this - Windows to Android media streaming?

Choppy is a generic term. The video player could cause it to play choppy (VPlayer is choppy for me, while MX Player is smooth).

Unfortunately there are a LOT of variables that will affect the performance. The VPN itself shouldn't really have an impact on how smooth the video plays (at least not on the tablet). The issue is most likely related to your internet connection and the software you are using to stream the video.

We would need a lot more details to determine what is going on, and you should probably create a new thread for this question.

Thanks but your answer does not help my question is explicit, anyways im going to try with VLC and report back, i know in the end i will figure it out. I could probably make a tutorial once i figure it out if anyone is interested.

I'd be interested once you figure it out.
