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.
Has anyone figured out how to get OpenVPN working on a Motorola Milestone?
I tried to using the OpenVPN Installer and OpenVPN Settings apps from the Android Market but was not able to get it working.
Made some progress but still not working...
I've managed to install the OpenVPN binary to /system/bin.
Got a Motorola Milestone Tun.ko driver from, http://code.google.com/p/sbdtools/downloads/list. It's been copied to /system/lib/modules. I've been able to enable it using the insmod command in adb shell. Verified it was running with the lsmod command.
I've moved my openvpn .ovpn config files to my SD, /sdcard/openvpn folder. Started the OpenVPN Settings app, configured the tun and path settings.
Then I started my connection and was able to obtain an IP address.
BUT... still not able to surf to Youtube or other China blocked sites.
The upload & download stats appear to be not moving, even when I try to surf to one of these websites (up: 0.02kBps - down: 0.02 kBps).
Will continue at it for some more, but if anyone is able to help, that would be much appreciated.

Hi, same here.. I am based in China and have done the steps you mentioned... I can connect to OpenVPN but there is no traffic.. I subscribe to 12vpn and called the helpdesk, they told me it could be due to DNS poisoning.. but really doubt that.. I got it working like once the first time but never did again...
@ pointdexler & dysa
I've also installed open VPN to system/bin on the droid 2 running 2.2.19. My config and certs have been transfered to /mnt/sdcard/openvpn and I've also setup my config in the open VPN GUI (available on the droid market) to point to this directory for my config.
After launching the app and attempting to connect, I get an error message that the command was not successful (the error is a bit more verbose than that).
I did find another app on Droid market that got me a bit closer to connecting called openVPN settings. The error output on this app is much more verbose and aids troubleshooting better. I was able to workout all of the application problems, but my issue now is with the tun.ko module. It appears that the downloadable modules online are for 2.1 and prior as none seem to work with 2.2. I have the module copied to /system/lib/modules and the app (openvpn settings) has a feature that loads the module (either by modprobe or insmod, you can choose). My problem now is that the tun.ko module seems to be wrong as I keep getting the error "Fatal: cannot allocate tun/tap dev dynamically."
Have either of you come accross this same issue?
Hi, I have running OpenVPN without problems. I use OpenVPN Settings from market, tun.ko on /sdcard and openvpn binary in /system/xbin. Make symlink ln -s /system/xbin /system/xbin/bb. Both files are in this archive http://www.android-hilfe.de/attachm...openvpn-auf-dem-milestone-tun_und_openvpn.zip. Working openvpn.ovpn + CA files in /sdcard/openvpn. In OpenVPN Settings set up Load module using - insmod and Path to module /sdcard/tun.ko. And OpenVPN is working. If not, try run from konsole : insmod /sdcard/tun.ko
Motorola Light 2.1 ROM + JIT
On CyanogenMod 6 for Milestone you need only tun.ko. No openvpn binary, no create symlink. In OpenVPN Settings only set up insmod and path to tun.ko.
(and sorry for my english )
OpenVPN
No worries ZS-Man, your English is much better than some people who are born speaking the language.
I unfortunately already tried loading the kernel module by command line with root (#) access and it gives me this error message:
insmod: init_module '/data/tun2.ko' failed (Exec format error)
I've tried many different versions of the tun.ko file available online. None seem to work with 2.2.20 OS (2.6.32 kernel)
Android version (2.1 or 2.2) is not important, only tun.ko must be compiled from same sources as kernel. You must search module for milestone2, or compile it by yourself from milestone2 kernel sources. Another nice app is Tunneldroid , it has log viewer - good for debugging openvpn connection.
help help help vpn issue
iam from a country that google does not support the market within
i installed the vpn and all works great market apps every thing but 3days later
the market wont open looks like the ip address from us has been blocked(internet sharing device located in us) and i was unable to open market again any way that i can chage the ip or howoften the company changes the ip address (cause its the same every time i connect vpn) or is there a way to use the vpn settings with another server provider than the freeopenvpn.com
where i can download another zip file with configuration to another server
help me please i ll die
Hi,
does the HTC One has CIFS support?
So that the CifsManager can be used on a rooted device?
THX
Well the app is showing as compatible on the Play Store, so I'd presume so.
No it does not.
Just because cifs manager can be downloaded doesn't mean it has Cifs support.
You need a custom rom / Kernel for that.
There are two kernels out there claiming cifs support, however I cant get either one to work.
http://forum.xda-developers.com/showthread.php?t=2235085&highlight=cifs
and
http://forum.xda-developers.com/showthread.php?t=2233665&highlight=cifs
Let me know if you get one working.
Update: there is a 3rd Kernel claiming Cifs support.
http://forum.xda-developers.com/showthread.php?t=2229300&highlight=cifs
I will try it our soon.
Any updates on this? Would love to have CIFS support and TAP network driver support. I'm thinking about trying to compile my own kernel modules but I have almost zero experience with doing this...
cifs.ko loads, but no success

I've gotten a cifs module to load on 3.4.10 after modifying the module final version string to reflect my specific kernel (3.4.10-geb45596) but still no success. I had success doing the exact same thing on my old EVO, but CifsManager on the HTC One throws "invalid argument", and the mount command (via terminal) says "no device", although lsmod confirms that cifs is loaded.
Any advice is welcome.
I'm also stuck trying to get CIFS.
Can you flash any kernel, regardless of ROM, or does it have to match? I'm using an Android Revolution HD GPE ROM, which doesn't appear to have CIFS support ("invalid argument", cifs.ko nowhere to be found in the filesystem according to ES File Explorer, /proc/filesystems/cifs (or something like that) does not exist, etc).
Maybe I could just flash one of the above kernels and see if it works, or does it not work like that, i.e. it has to be integrated with the ROM?
tried to use an OpenVPN app, but apparently this phone doesn't have the required TUN module. i've already tried the TUN.ko Installer App, but there's no TUN module for this phone yet. anyone know if there's a current kernel that has the TUN module active or how i can get the TUN module for this phone??
TIA
phone model: HTCONE
build number: JZO54K
android version: 4.1.2
kernel version: 3.4.10-g30a4e11

I don't know the answer, but I've had it working on the 4.2.2 Sense version.
I'm not sure kernel modules are required. After firing up OpenVPN Connect and connecting, I don't have a tun module loaded, but it could be built into the kernel.
ip route show shows a dev tun0 whilst connected.

i use Private Internet Access's app, which uses OpenVPN. it works just fine when i'm using WiFi, but when I'm using 4G i can't load any videos from the youtube/vimeo app.
their tech support thought i may be something to do with my ROM lacking the TUN modules. that's why i tried the TUN.ko app, but apparently there aren't any TUN modules for my phone. i'm using the most current ROM for Sprint version, which was slightly modified (still Android 4.1.2) http://forum.xda-developers.com/showthread.php?t=2391234
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 !
