tun.ko for NEXUS ONE available?

as I am behind the GFW of CN I am eager to get openvpn to work (trying with TunnelDroid, with vpn binaries of WITOPIA...
unfortunately i can't get the connection to work, and apparently it is because of the lacking tun.ko
I took the only tun.ko I can find online (vpn connnections, for DROID...), but apparently the current Nexus One kernel does not support.
Does anybody have a tun.ko file that works on Nexus One?
thanks....

I have the exact same problem.......I need a tun.ko to start using witopia to get through the stupid ISP block on google Voice !!
So if anyone has any working tun.ko PLEASE PLEASE help us out !!

I got it !!
Finally......I managed to extract the tun.ko from Modaco's latest build, so credit goes to Modaco for this, I just extracted it for those who like to stick to Stock Roms (like myself for now).
I tested it and it works

How do you guys like openvpn on android? is it pretty stable? Has anyone tried using Access Server?

Are you sure you're running the stock OS?
I am still getting those messages:
insmod: init_module 'tun.ko' failed (Exec format error)
and in dmesg:
tun: version magic '2.6.29.6-cm-teknologist-0.1 preempt mod_unload ARMv7 ' should be '2.6.29-01117-g4bc62c2 preempt mod_unload ARMv7 '

@chirayu : Well, I dont like it so much right since it still needs ALOT of work. Its lacking ALOT of things right now.
@sjakub : Yep, im running the latest ERE36 update. But yea its a stock image.
I didnt see any of the errors you mentioned. I got differnet errors while I was trying it with Witopia, which didnt really work out, but it doesnt seem like a tun driver issue, it was something about an encryption key not available, still working on that.

I have ERE27, that could be why. Where did you get that update from?
Can you get some other module from that phone (like bcm4329.ko) and look for 'vermagic' string inside?

Also, how did you extract tun.ko from that build? Maybe it's possible to extract one from the ERE27-based build?

Well, the tun.ko is tested and works fine on ERE27 and ERE36 updates so that shouldnt be the problem.
As for the other files, like bcm4329.ko . Why would you need that ? It should be there by default ? as far as i know that module is responsible for certain wireless activities, I do have that file with me if you need it.
As to how i extracted, its simple.....I made a NAND backup of my stock image then flashed Modaco's latest update including the tecknologist kernel which supported tunneling and therefore included the tun.ko. Copied the file to the sdcard, then restored the backup and copied the files to /system/lib/modules

I don't NEED that module.
I would like to know what is the value of "vermagic" inside.
This is the string that describes the version of the kernel used.
Now, if it's something like '2.6.29-01117-g4bc62c2' and the one in the tun.ko you posted is '2.6.29.6-cm-teknologist-0.1' it means that you're somehow able to load module that has a different vermagic than a kernel. If the vermagic in bcm4329.ko is '2.6.29.6-cm-teknologist-0.1' it means that you have a different version of the kernel (and not the stock one). I have no idea why it would be working with ERE27 in that case, unless it was modified ERE27, not the stock one. Or, you were able to load an incompatible module somehow. In that case I would start investigating how to do that with my kernel as well

Hm, or you could check you phone's info:
Could you, on your phone, go to "Settings->About phone" and check what it says under "Kernel version"?
Thanks!

Finaly! I figured out how to build tun.ko module for the stock kernel.
If anybody wants to repeat that:
* I have Android OpenSource installed in /opt/android
* In /opt/android I did: git clone git://android.git.kernel.org/kernel/msm.git kernel-nexus
* In kernel-nexus I did:
- git checkout -b origin/android-msm-2.6.29-nexusone
- git checkout HEAD^
(The last operation reverses one revision, I needed a previous revision from the tree. Different revisions generate modules with different vermagic values)
(Actually, instead of previous two this should work as well - it should checkout the correct revision: git checkout 4bc62c230b2942bea72c3b5258e3e4f1d6cb534b )
- make ARCH=arm CROSS_COMPILE=/opt/android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- distclean
- adb pull /proc/config.gz
- gunzip config.gz
- mv config .config
- Edited .config: changed "# CONFIG_TUN is not set" to: "CONFIG_TUN=m"
- make ARCH=arm CROSS_COMPILE=/opt/android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- modules
- The driver ends up in: drivers/net/tun.ko
- You can verify if it is going to match the kernel by running:
+ strings drivers/net/tun.ko | grep 2.6.29
+ It should produce "vermagic=2.6.29-01117-g4bc62c2 preempt mod_unload ARMv7"
+ The "2.6.29-01117-g4bc62c2" should be the same as the "Kernel version" in "Settings->About phone" on your phone.
* Now you can upload the module to your phone. I did:
- adb shell mount -o remount,rw /dev/block/mtdblock3 /system
- adb push drivers/net/tun.ko /system/lib/modules/
- adb shell mount -o remount,ro /dev/block/mtdblock3 /system
- And you can use adb shell, enter /system/lib/modules and run: insmod tun.ko
- It should work
The module is attached.

hey Sjakub..
I have tried using your module and I got the same thing like with the one i extracted from Modaco's mod. The tunnel droid gets stuck at "Connecting" any ideas?
Thanks again for all your work mate appreciate it !

Cyanogen Roms have built-in openvpn support. I don't have any problem using Tunneldroid on CM 5.0.4.1. I got the tun.ko error only when I was on the stock ROM. I'm also behind the GFW. Witopia does the trick for me.

thank you sjakub~i used to use your tun.ko working very well with tunneldroid.but after i update the kernel that supports tethering.the tun.ko doesn't work... the new kernel version is:2.6.29-gad36b87-dirty...

The tun.ko module has to be compatible with the kernel you have. Where did you get the kernel from? You need to find a source of exactly that kernel version and compile tun.ko yourself.

i download the kernel for my nexus one from here ——code.google.com/p/android-wifi-tether/
and i follow the steps in the site to flash my rom :code.google.com/p/android-wifi-tether/wiki/NexusOneKernelUpdate
finally...i'm not able to use the previous workable tun.ko which you built...and i'm afraid that i was too amateur to complie tun.ko myself even though you have already list out the compiling steps...

Try asking authors of the wifi-tether for that module. That's probably the easiest way

okay~i manage to browse that source in google code,though,i can't found tun.ko module.or maybe i will flash cyanogen rom which consist of all the necessary things

anyone brewing a tun.ko for nexus one froyo stock kernel. I don't see aosp code to build right now.

[Q] CIFS support in kernel

I am not a developer, and I know NC just rooted in few days but we have made great progress to make NC as a full function tablet. I am just curious to know how far we leave to have a CIFS supported kernel.
My dream is quite simple, I want my NC can play tons of video files in my NAS via wifi, so CIFS kernel is the first step to make it true.

Kernel version
If someone can tell me the Android kernel version that is on the NookColor I can experiment with CIFS.
Thanks in advance,

according Nookdevs,
Operating system Android 2.1 (Eclair based on Linux kernel 2.6.29)

If we can get CIFS support then we can use CIFS manager to mount shares locally.
and use rockplayer or the built in media player to play videos over wifi.
http://forum.xda-developers.com/showthread.php?t=756158
I wonder if we can compile the CIFS.ko module from the source released by B&N.
I will have a look over the weekend if time permits.

hi dascud,
nice to hear you will have a try and waiting for your good news.

i'm not a *nix developer, but since we can install Optware on the NC can we install the samba packages and achieve this?

Samba is probably too fat for the nook. CIFS kernel support shouldn't bo difficult. Mounting the shares directly is way more efficient.

So I downloaded the source and compiled the cifs module and the nls_utf8 modules.
modinfo shows that the modules version is
vermagic: 2.6.29-omap1 preempt mod_unload ARMv7 which matches with the running nook kernel.
Unfortunately no luck trying to insmod the modules.
I think the running kernel may have no support for loadable modules and we may need to recompile and replace the stock kernel for loadable module support.
If anyone else wants to give it a shot here are the links to the compiled modules.

I only dabble in Linux so I may be way off here, but I'm pretty sure there's loadable modules in the firmware that are being used.

Ok. We have a working cifs.ko and nls_utf.ko . I was able to mount my win7 share using cifs manager and play a few movies using mvideoplayer from the mounted share.
My initial problem seemed to be that I used the android ndk toolchain and the nook kernel is compiled with the codeSourcery toolchain.
After I re-compiled using the codeSourcery toolchain everything works (at least for now)
For those who want to try this.
Download the cifs.ko and nls_utf8.ko modules.
http://dl.dropbox.com/u/16190398/cifs.ko
http://dl.dropbox.com/u/16190398/nls_utf8.ko
Mount /system as read write and create a directory under /system/lib called modules. Just copy the cifs.ko and nls_utf8.ko modules under this directory.
Type the following from your windows or linux console.
adb shell
#mount -o remount,rw /dev/block/mmcblk0p5 /system
#su
#cd /system/lib
#mkdir modules
#exit
#exit
Now you are back in your windows or linux command prompt
adb push cifs.ko /system/lib/modules
adb push nls_utf8.ko /system/lib/modules
adb shell
#su
#insmod /system/lib/modules/cifs.ko
#insmod /system/lib/modules/nsl_utf8.ko
if everything went well you should see no errors.
#lsmod
(THis should give you a list of running modules)
You should see something like
nls_utf8 1856 0 - Live 0xbf153000
cifs 240060 0 - Live 0xbf113000
#exit
#exit
Download cifs_manager from the android market and follow the instructions from
http://forum.xda-developers.com/showthread.php?t=756158
BTW, you can copy the modules anywhere you like even under /sdcard/modules but the default path used by cifs_manager is /system/lib/modules.

Awesome! I am eager to try this out. I have CiFs working on my EvO and it rocks.

Cool! Dascud, you are the man!
I will have a test after upgrading my NC to 1.0.1.
Thanks a million for your efforts!

Nice.
Installed the modules and cifs manager (which I haven't used before.)
Just set up a test share...
NC rebooted.
Booting again now, not sure what is up. I have not had any file sharing configured on my network for a while so its entirely possible that I have a share misconfigured or something not installed. Late now, so I will try more tomorrow.

can somebody please reupload
cifs.ko
nls_utf8.ko
They are not on dropbox any longer.
Thanks.

There you go....

thank you ser

Does anyone know if this will work in rooted 1.2? tried the steps as described, have cifs.ko and nls_utf8.ko in /system/lib/modules, but all I get is "Exec format error"
Any ideas? Thanks!

[Q] Change x8gesture in nAa10.

Welcome. Can I change a module responsible for fake dual touch in kernel nAa10? Module in this kernel is inaccurate and does not have gamemode for synaptics.

if you want to remove the fake dual touch module then delete the file named x8gesture.ko from
system/lib/modules.
PRESS thanks if I helped

Wrong! If you delete, the system will re-create them at boot.
------------------
To change dual touch module (by DX - works much better), insert this line in your /system/etc/hw_config.sh
insmod /system/lib/modules/synaptics_i2c_rmi4_dt.ko
To completely disable dual touch, insert this: (but at least for me, its not working)
insmod /system/lib/modules/synaptics_i2c_rmi4_no_dt.ko

[Q] How to overclock gingerdx v25 :( ??

recently installed the super awesome GingerDX but how to overclock it..???
1) flashed the file provided in the gingerdx thread still dint work
2) tried to paste x8oc.ko in modules using root browser ... it says "failed to paste"
Please Help !

Ive flashed this rom n overclock works great. Try flash again and then flash the overclock modules. Dont reboot after flashing the rom. Flash the modules directly while on cwm.
Hit thanks if i helped..
Sent by my w8 using XDA app........

For setting value of CPU & Activate oc, (in Cyanogen-mod setting doesn't provide) without using paid app like SetCPU, (After installed stock oc.zip)
in terminal type:
su
insmod /system/lib/modules/x8oc.ko
echo "xAB" > proc/x8oc
The AB represent integers... 28 = 768 29 = 787 (Occasional reboots)
Above i believe stock user will have reboot...
you can put the echo "xAB" > proc/x8oc into hw_config.sh to set on boot clock speed.... but be aware that value above 28 are not suitable for set on boot clock speed
Download Zip file : http://www.mediafire.com/?ubdt8kjgamo09nz (This contain x8oc.ko files)
For easy overclocking, use this https://play.google.com/store/apps/details?id=os.tools.scriptmanager&feature=search_resultit should simple as it goes, like terminal, but it's better.... What's more it can create a widget

Or if u failed to paste, use root explorer and tap the small box.until it changes to r/o. Then paste again. After that go to emulator and do the above procedure.

[Q] Tun.ko module

Hello,
I am trying to create a tunnel interface on my phone( which has the latest Cyanogenmod 10.2 ) by using this command:
Code:
ip tuntap add dev tun0 mode tun
I get the following error: open: No such file or directory.
I did some research and, apparently, this happens because I don't have installed the tun/tap drivers( the tun.ko module ).
Does anyone have any idea on how to get/install the tun.ko module on my phone ?
Thank you !

I don't guarantee that there will be an module for your kernel, but you can still try

I tried it, but it says:
TUN support is possibly pre-loaded in your kernel.
Click to expand...
Click to collapse
This might suggest that the module might exist, but I double checked with lsmod and the /lib/modules directory.
If you have any idea about a kernel version for the phone that might make the Tun.ko app actually install the module, please share.
Also, if anyone else has a working tun.ko module, the Tun.ko app has an option where you can share your module( probably it's sent
to the droidvpn site ).
Thanks !
