Not yet, but I am using the CyanogenMod 4.0.1 on my Dream and I have seen Donut on the HTC Click -- in both cases, Settings --> Wireless Controls is showing an option for VPN Settings, so I'm guessing that it would be a matter of time before this is available on the Hero and Magic firmware
Be patient, or wait for someone to cook a ROM with this feature

VPN wil be in Donut.
For now, it seems possible to implement it.
For the program GUI, it should good to extand that program to support openvpn and pptp vpn.
First of all tun driver is needed, you'll find it here.
Install and, as root, type:
# insmod /system/lib/modules/tun.ko
lsmod command should give you:
tun 11300 0 - Live 0xbf000000
That should load the tun kernel module.
I think we should then have to compile openvpn using android ndk.
A guy did it for the dream. Worth trying it. Maybe someone else could tell if binaries compiled for Dream can work on Hero

OpenVPN ist working on hero. I used the binaries for the G1. But the CIPHER is different: AES-256-CBC. I'm now testing it and if it's stable, perhaps I'm gonna compile openvpn with complete static openssl, so all functions should work.
If someone is interested, I can post my scripts and settings.

I am REALLY interested to now how you compiled it.

Hi!
I haven't compiled openvpn until now. I used this one:
https://www.digital-bit.ch/wiki/OpenVPN_auf_dem_G1

Just tried, may work. But i can't connect to my astaro because the key needs auth wit user and pw.
This Version hasnt been compiled with --auth-ask-pass. And reading from commandline doesn't work either..

I did compile it on my G1 with CyanogenMod ROM.
As far as I can see, it is working perfectly: I'm using it with certificates for 3 different VPNs.
Only issue: I wasn't able to complile a shared version of liblzo, so the binary is statically linked against liblzo.a (751 KB... )
Ah, yes, of course no GUI interface, shell only...

Hi!
Cool, could you post the binary? Could you give me a hint how you did it? I had several problems.

Would be perfect if someone could compile openvpn with " --enable-password-save"

Please post it, when a OpenVPN GUI for the HTC Hero / Magic is available.
Thans alot

The great spam protection measures in this forum deny posting links for new users, so you have to manually follow them.
See: github.com/fries/android-external-openvpn
There is also an app and a statically linked openvpn binary at github.com/fries/android-external-openvpn/downloads
The openvpn binary has the following features:
* --enable-password-save
* statically linked against a blowfish enabled openssl
* statically linked against liblzo
Build:
* openvpn-static.bz2 was build on a donut-tree (1.6) for htc-magic
* openvpn-android-2.1.tar.bz2 was build on a cupcake (1.5) tree for htc-magic
* should run on a verity of (rooted) phones, please try it an give feedback.
A dynamically linked version is also available. The above git repo integrates seamless into the android build system. Some instructions may be found here: wiki.github.com/fries/android-external-openvpn/
Any feedback is welcome. Enjoy.

read this first -> http://sourceforge.net/projects/tunneldroid/files/README/download
First make sure kernel is compile with tun module
install tunneldroid from market
binary download -> http://sourceforge.net/projects/tunneldroid/files/openvpn-binary.zip/download

The newest version of my 'OpenVPN Settings' app is available at github.com/fries/android-external-openvpn/downloads

working VPN modules 2.x roms

Hello,
I compiled the missing vpn modules for the hero eclair kernels (2.6.29-8d063048 and 2.6.29-877eaf14).
modules compiled: tun + all ppp (l2tp not tested pptp and tun with openvpn working).
For openvpn you need de openvpn package and tunneldroid (market).
all files are packaged as update.zip
happy tunneling

Didn't check yet, but why are your libs and binary so big?
Did you enable debug? Didn't you strip symbols?
In contrast, my openvpn binary is barely 350Kb.

The openvpn binary and libs are not mine so i can't say anything about that. Changed openvpn for smaller version.

thanks for the work!
but i tried villian2.1 rom and espr 1.3 rom(the kernal version is 2.6.29-8d063048),non of these works.
could you please put more details on your fix?

OK, i figured it out. Only problem with villain rom is it doesn't run the 05vpn init script in /etc/init.d/. It's a known problem in the villain rom (i checked the villain thread and saw multiple posts about that).
you could try this:
install Autostart from market
adb shell
mkdir /data/opt
echo "sh /system/etc/init.d/05vpn" > /data/opt/autostart.sh
chmod 4755 /data/opt/autostart.sh
reboot phone
There will be an su request. I need to restart my phone a second time, but after that it works.

thanks dude!
it's now woking well!!

Tun.ko in HTC Stock Rom

Hey,
Not sure if this is the right forum or not. But I have tried a few places and ended up with no reply or a dead end so I'm hoping I will actually get some where here.
But is there any way that makes it possible to get tun.ko working on a stock HTC Desire rom?. I have been searching for god know hows long to find any help or instructions on the matter without much help being offered :/
Its because I want to run VPNC on my Desire and I got all the stuff bar tun.ko, so that is the only thing stopping me from going any further and any and all help will be appreciated.
Kind regards.

Yes, you can download the desire kernel from http://developer.htc.com/
You also need the build toolchain for arm processors, find it on http://developer.android.com/sdk/index.html
You need to root your desire, so you can copy files to the system partition. http://unrevoked.com/
The kernel .config file for making oldconfig is , as far as I remember, delivered with the kernel package by htc. If not you can get it from your phone.
Build tun as module, and copy it on yor device.
Hope thats a good quick start for you.
malachay.

It helped somewhat, althought I am not sure how I actually build something as a module etc considering I dont really have much in the way of linux/unix experience.
But my phone is both rooted and S-OFF.
So considering my lack of experience with these things a more elaborate/comprehensive guide or just the steps I need to reproduce to actually build the file as a module, would be greatly appreciated.

You don't have to build one per say, you just need to find the Tun module (Tun.ko) for your specific kernel.
If you go to the "About phone" -> "Software Information" section, you'll see a Kernel version.
For example, the phone I have is using Kernel 2.6.32.15-gf5a401c - so I have a tun.ko that loads for that kernel.
There's quite a few TUN modules posted on this forum for various versions of the HTC kernels.

If you don't find a module that fits your kernel version , I can build it for you if you want.

My kernel seems to be the same, so would you mind sharing your tun.ko and possibly any instructions on how to get it on my phone and working ?
But my kernel version says: 2.6.32.15-gf5a401c

Here's the tun.ko I made for my ROM:
Tun.ko for 2.6.32.15-gf5a401c
It's not a flashable zip though, you need to push it to your phone using ADB (or use QtADB if you want a UI program to help you).
You need to put it in /system/lib/modules/
To load it, run terminal emulator on your device (it's free on the market) and run the command:
Code:
insmod /system/lib/modules/tun.ko
Although, if you're using a VPN application on your phone, the application might have an option to load the TUN module for you - so the insmod command might not be needed.

Mekrel,
Do you have the "exact" ADB command on hand?. Because I know how what ADB is for, but doesn't know the commands etc by heart

This is the error I get when I try :/
D:\Test\android-sdk-windows\platform-tools>adb push D:/tun.ko /system/lib/module
s
failed to copy 'D:/tun.ko' to '/system/lib/modules/tun.ko': Read-only file syste

Hi!
Seems like there is the same problem on all Android devices. OpenVPN requires the tun.ko kernel module that is hard to get. And it also seems like it must be compiled more or less exactly to much your rom version :-( .
I have a HTC Desire HD running stock rom kernel version 2.6.32.21-gf3f553d [email protected] #1
I have tried various tun.ko modules I have found, but none is comaptible; insmod tun.ko fails.
Questions:
#1 Where can the right version of this magical module tun.ko be found?
#2 Is it hard to compile it for the correct ROM?
#3 How? Isthere any good step-by-step guides.
This could also be a good way to get introduced to compiling kernel modules fro Android devices.

[Q]tun.ko module for 2.6.35.10 htc kernel

Hey all,
Anyone has got the tun.ko module for this kernel? Or anyone could compile one? Thanks!

Hi,
I tried to compile a matching tun.ko module. However, I have currently no possibility to test if it works. If someone wants to try it, I would be glad to hear, if it works or not. (As always, don't blame me, if it breaks anything.)
[Edit: OK. I removed this version, as it obviously did not work. A working tun.ko can now be found in post #8]

it loaded successfully but then i get FCs in settings ever since

it indeed does not work
I tried to use it in console
it loads OK, but when creating a tunnel interface the phone reboots unexpectedly
has anybody succeeded in building tun.ko against this 2.6.35.10-g0956377 kernel version?
thank you very much in advance

OK
since HTC has not release 2.6.35.10 kernel sources for DHD I was not able to build tun.ko against DHD kernel
I grabbed the only 2 kernel sources with this version that are available on developer.htc.com and tried to build tun.ko agains them
the one from HTC Desire S works fine on my phone
I will recompile it against DHD kernel once it gets released
so far you can try the one attached and report if it works or not
if was build with magic version number g0956377
just unpack
rename to tun.ko
insmod
and report if it works
Have a nice day
Martin

have not use

<s>Would you please build it against desire s's own g13f6602 ?</s>
thank you for the common idea

The official kernel sources for the 2.6.35.10-g0956377 kernel used in the 2.36.405.8 software for the DHD are now available. I have therefore compiled the tun.ko module again from these sources. This module works now also on my phone. You find it attached below.

Hi can anyone help me get a tun.ko for my HTC DHD, kernel is 2.6.32.21-gbe90714 ... Thanks

Can somebody please build tun module against 2.6.35.10-g13f6602 kernel?

Someone has already done this for this version of kernel (2.6.35.10-g13f6602), so tun module and everything else is in the archive.
openvpn got working
Posted by Karthik on May 8, 2011 in Android Support, Rooting and Mods | 0 comments
For those who have already rooted their phones and need ovpn, i’ve compiled tun.ko module, which suites stock ROM (2.6.35.10-g13f6602)
All you need is to put it into /system/lib/modules/ from the archive attached.
Also, you can find there working binary (and lib) from cm7.
Just place the binary into /system/xbin/ and lib to /system/lib/
Enjoy!

[Q] OpenVPN Support "tun.ko"

I was wondering if the Galaxy Nexus stock ROM had OpenVPN support in kernel and if someone was contemplating compiling tun.ko for the less tech savy users

Would also like to know if it's possible to use OpenVPN on the GN.

If it is not in there stock, I am sure one of the many kernel devs will add it for us.

Apparently...
"It should now be possible to write a OpenVPN client for Android."
According to:
https://code.google.com/p/android/issues/detail?id=3635#c87
So it's just a waiting game now for an app it looks like.

openVPN works
Hi,
Just wanted to let you know I got openVPN working. (pic below)
I have Revolution 1.3.0 ROM and Franco's kernel installed, both excellent I must add.
I didn't need a tun.ko, did on my sgs2.
There are 2 programs you need on the market, openVPN installer and openVPN setting. Run those and you should be good to go. The only thing I had to do was create a /system/xbin/bb folder and copy ifconfig into it. This may have been something to do with the way I installed busybox.

I use the last MCK kernel compatible with Android Revolution HD.
Will check if the kernel have support.
I can't wait to be able to watch Netflix from the USA again.

Unfortunately, stock ICS on the GN has no tun support. We still need a tun.ko. So far I didn't find one, so I guess I need to compile it myself...

I believe it stock ROM does have tun support. See this thread:
http://android.modaco.com/topic/349642-tunko-for-openvpn/
Steps are here for anyone else looking to get it working (which I gleaned from here http://forum.xda-developers.com/showpost.php?p=17233744&postcount=9):
Install Busybox from Market
Install OpenVPN Installer from Market and install to:
binaries: /system/xbin
route/ifconfig: /system/xbin/bb
Create /system/xbin/bb with Root Explorer or from shell
Create link to busybox for ifconfig and route
ln -s /system/xbin/busybox /system/xbin/bb/route
ln -s /system/xbin/busybox /system/xbin/bb/ifconfig

Indeed, you're right. Although my OpenVPN installer indicated my kernel was lacking a tun module, I justed ignored it and now I'm running OpenVPN on rooted/unlocked ICS. Great!
Mark

I would ideally like this to work without rooting. Hopefully a proper app gets made!
Great News though!

Indeed, I thought that I needed Franco's kernel to get openVPN to work, but when I flashed back to stock kernel (I had some battery issues) the openVPN still worked.

Everything worked fine, I can now connect on my VPN servers through OpenVPN Settings (On the Android Market) : D. Awesome ! Many thanks

Just in case you haven't heard yet: The official Cisco AnyConnect VPN Beta has been released in the market a week or two ago. It supports all ICS devices (tested it on my Asus TF101 with stock 4.0.3). Works great on my unrooted GN!

Help with OpenVPN setup
Hello,
I followed all the instructions on this post regarding install and reconfiguration of folder permissions. I'm running AOKP Milestone 3 and Franco kernel Milestone 2. My phone connects to openVPN but it's clear that data isn't flowing through it (i.e., I'm in China and still can't use Facebook or Youtube apps)
Any suggestions? OpenVPN app connects to the server very quickly but when visiting Facebook.com, I can see very easily that the download rate is 0.0kbps, then the page times out.
Any help would be appreciated!

Does this work with open vpn? Sorry if this is a dumb question, I am a new user to open vpn. I am about to setup an open vpn server on my dd-wrt router.

does anyone know where the tun.ko module is located on stock rom?
i can't find it no matter how i search for it. will it be possible for someone to upload it and give us the link?
thank you...
