OpenVPN?

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...

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 )

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

Steps to make OpenVPN Work

Here are the steps I took to make OpenVPN work. You HAVE to be rooted to make this work.
1) I am going to assume you already know how to configure the firewall side and export a legitmate config.
2) I am running TnT 4.2.2 (great ROM IMHO)
http://forum.xda-developers.com/showthread.php?t=842004
3) I had to run Clemsyn's kernel to get the tunnel to nail up. I don't beleive the stock kernel or any of the TnT mods will fix that.
http://forum.xda-developers.com/showthread.php?t=895825
4) Download from market OpenVPN Installer AND OpenVPN Settings.
5) Run OpenVPN Installer first. I selected /system/xbin option on all screens.
6) Make a folder /sdcard/openvpn. Copy your vpnconfigname.ovpn and vpnconfig.p12 files into it.
7) Run OpenVPN Settings. I unselected "Load tun kernel module" option, the "Fix HTC Routes" and (optional) "Show Ads". I did not alter the "TUN module settings in any manner.
No guarantees, but this worked for me without any fiddling.
-D

I'm not being so lucky - I installed Clemsyn's kernel and the same OpenVPN settings / key that I've installed on my Galaxy S so I know they're functional.
It connects and auth's, creates the TUN device, but shows "Connect to (myserver) as" and netcfg always shows:
tun0 DOWN 0.0.0.0 0.0.0.0 0x00001090
It never brings up the tunnel IP on it.

Well I got it working.
I had to install BusyBox from the market - the "FileBox" versions apparently installed in my rom wouldn't do it.
Then I created /system/xbin/bb/route and /system/xbin/bb/ifconfig linked to the /system/xbin/... versions installed by BusyBox.
I even downloaded and installed the statically linked executable from https://github.com/fries/android-external-openvpn/downloads and thought that fixed it, but turned out the MD5 of that and the market one were identical.
*** EDIT ***
Actually the OpenVPN I installed WAS different from the Market and appears to be the actual fix for me. I must have checked the wrong file the first time with md5sum because I double checked the backup I copied to the desktop and it was definitely different.

[Solved][Zeus v6.36+patch v2] : openvpn not complete ?

Hello
I'm testing this nice rom since 3 days.
After an update from googleplay, openvpnsetting now opens a prerequisite screen and check my device for root, busybox tun.ko and openvpn binary.
It's all ok , just TUN device driver isn't installed . Is this device mandatory for using openvpn ?
[edit] Okay, after searching a bit on openvpn, it seems that tun is not mandatory. Explanations here
Most of openvpn settings use TAP device, so missing TUN should not be a problem...

It just need to copy tun.ko from /etc/modules to /system/lib/modules... It will be done for next release, but anyway you can do it by yourself via root browser.

Tested : works fine, but had before to create /system/lib/modules with root permissions
Thanks a lot.

[Q] TUN module for OpenVPN

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

[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.

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 !
