Has anyone managed to get openvpn going? compiling custom tun.ko file for DHD?
It's probably possible, now that we have the source. Don't have a DHD just yet, so can't try
Sent from my HDfied HTC Desire

hello
i'm interesting too for the kernel mod tun.ko for the DHD
any reponse ?
Hello,
i'm very interesting in this file too...
My NAS awaits the phone "call".
Hey everyone. First time poster, so hoping its a happy reply
Has anyone had any luck with this ? i also require the tun.ko file for DHD. been searching the net for hours
looking forward to your replies.
I heard that tun.ko file has to be specifically compiled for each kernel version. Is that right?
Is it also linked to the radio version?
If we could have a link for kernel source, i might be able to follow tutorial and publish it here.
I have 2.6.32.21 -g66cfb7a kernel version and you? (not sure if the second part is part of the kernel version)

Attached is tun.ko for the Desire HD (for kernel 2.6.32.21-gf3f553d). Built it today & it seems to insert OK and work fine with VPN Connections.

Perfect! Thanks!!
Very thanks for the module.
DHD - tun.ko for 2.6.32.21-g66cfb7a

Yes. After trying other people's tun.ko modules, it wasn't until I checked the output of dmesg that I learnt this (got my first Android 3 weeks ago - so I'm still a n00b).

Lionel, it would appear that my Desire HD has the same kernel.
2.6.32.21-g66cfb7a
2.6.32 is the base kernel version
I assume 21 is the revision or build number.
The hex string on the end seems to vary by which ROM you have installed. This was what was stopping me from loading these other tun.ko modules - including the one posted by @thedji
I've just compiled the tun.ko module for 2.6.32.21-g66cfb7a (on a headless Pentium 2 400 MHz lol). It loads fine and can be seen in the output of lsmod. I've attached it below.
Edit: I was able to use this module successfully to connect to a Cisco VPN with vpnc.

Can you explain to me how and with what Software you connected to a Cisco VPN?

First - applications.
1) You're going to need a terminal/console app. I used one called Terminal Emulator.
2) You're going to want an app called "VPN Connections". I downloaded a patched APK in post #4 here:
hxxp://code.google.com/p/get-a-robot-vpnc/issues/detail?id=122&q=patch
Alternatively, you might get it from here: hxxp://code.google.com/p/get-a-robot-vpnc/downloads/list (although YMMV).
Second - setup.
1) You're phone needs to be rooted.
2) You need to have the appropriate tun.ko module (for your phone's kernel) loaded. Load up the Terminal Emulator then:
a) Type 'su' without quotes and hit enter.
b) Type 'insmod /path/to/tun.ko' without quotes and press enter. If your tun.ko is on your sdcard in the root, the path would be /mnt/sdcard/tun.ko
c) If the step above worked, you should be able to type 'lsmod' and see the tun module loaded.
Note: I didn't have any luck running the "VPN Connections" app directly - the connection kept failing (possible due to the configuration of the VPN I was connecting to). So I start it from the command line. You might want to try using the GUI first as it would make things so much easier if it works.
Third - connecting to the VPN by a command line.
1) The command to enter is quite long (and I got sick of typing it), so I put it into a file called 2.sh in the root of the sdcard.
2) Inside the file /mnt/sdcard/2.sh, I entered the following:
Code:
/data/data/org.codeandroid.vpnc_frontend/files/vpnc --script /data/data/org.codeandroid.vpnc_frontend/files/vpnc-script --no-detach --natt-mode cisco-udp --debug 1 --gateway AAA.BBB.CCC.DDD --id groupid --username mike --enable-1des
Note that the gateway is the IP address of the VPN you are connecting to. The username for me is just my username - it isn't prefixed by my company's active directory domain.
3) Open the Terminal Emulator.
4) Enter 'su' without quotes and press enter.
5) Enter 'sh /mnt/sdcard/2.sh' without quotes and press enter.
6) You will be asked to provide the group password, then the personal password for your username. Then it should attempt to connect.
You can change the debug value to 2 or 99 if you want to get more information (if it doesn't connect successfully).
If you want to know what command line options are available, enter the following at the Terminal Emulator:
Code:
/data/data/org.codeandroid.vpnc_frontend/files/vpnc --script /data/data/org.codeandroid.vpnc_frontend/files/vpnc-script --long-help
I think that's it - I hope this helps. After disconnecting I tend to do a long reboot (takes 1-2 minutes) to get the network back to the way it was; although I'm not sure this is necessary.
Mike
Edit: seems like you need to create a directory and a symbolic link. This is my working script:
Code:
mkdir /dev/net
insmod /mnt/sdcard/download/tun.ko
lsmod
ln -s /dev/tun /dev/net/tun
/data/data/org.codeandroid.vpnc_frontend/files/vpnc --script /data/data/org.codeandroid.vpnc_frontend/files/vpnc-script --no-detach --natt-mode cisco-udp --debug 1 --gateway AAA.BBB.CCC.DDD --id groupid --username mike --enable-1des
Damn I hoped it woulld be easier. As I have never worked with Android that sounds like a challenge to me. So there is no easy switching on and off of the VPN connection? I always have to use the scripts?

Because the "VPN Connections" GUI app didn't connect for me, I had to resort to the script - you may not need to (depending upon the configuration of your Cisco VPN box).
I just need to run the final script (the 5 liner above) to connect to the VPN - good enough for the time being. You just need to modify the path to tun.ko, set your gateway server, groupid & username.
I hadn't worked with Android before the weekend just past - I've just rooted my first Android phone. It's all a learning experience - I guess it depends how badly you want VPN access? Hopefully it will get easier in time as the apps improve.
Good luck!

You can use something GScript to make it a two-click process (open app, click script). It's just as efficient as using VPN Connections (open app, click connect).
For me personally, I use VPN Connections to connect (successfully) but the traffic is routed down the wrong interface (i.e. not tun0).
After connecting I have to run
Code:
ip ru del table wifi
or
Code:
ip ru del table gprs
to fix the issue.
You should definitely try VPN Connections first. If that doesn't work, try the long method above.

GScript is a great idea - it will save me doing any typing to connect to the VPN.
Once I added these VPNC flags (--natt-mode cisco-udp --enable-1des) to "VPN Connections" I was able to successfully connect after running the script in GScript.
It doesn't say I'm connected, however my IP address has been assigned and I can Remote Desktop to my work PC. My routing already seems to be ok, so I don't to run the 'ip ru del' commands that you do.
I'm pretty satisfied with this now... no typing - just point and press.

What about tap.ko? (needed for OpenVPN bridge mode)

What kernel version are you running? If you have '2.6.32.21-g66cfb7a' I could compile tap.ko for you?
Hello Everybody,
I would like to change MAC address of wifi card in my atrix, but i cant:-(
I am rooted, i use Nottachtrix 1.2.4
With Terminal Emulator i try both options:
su
ip link set eth0 address 00:12:f0:dd:cc:dc
ifconfig eth0 hw ether 00:12:f0:dd:cc:dc
I do not get any error but MAC is just not changed.
Any ideas how to Fix this problem

I'm trying to setup OpenVPN with TAP (I know there are other app that set up TUN for you, that's not what I'm trying to do) on andriod, everything seems to be working correctly except the last step. When open vpn tries to add route it fails with error status: 1.
I followed the steps here to install Busybox/OpenVPN Installer/OpenVPN Settings
http://strongvpn.com/setup_android_open.shtml
My VPN seems to connect fine but it fails on
/system/xbin/route add -net 0.0.0.0 netmask 128.0.0.0 gw 10.1.1.2
I've double checked that /system/xbin/route can be executed, though when I'm trying to run the same command in terminal it gives me
siocaddrt operation not permitted
Any thoughts?
I guess no one uses OpenVPN with TAP eh?...
I don't know if this is the right category,but...I tried to change my MAC address following this tutorial:
"ip link set NAME down
ip link set NAME address ....
ip link set NAME up"
but when I write "ip link set wlan0 down" and press enter my tablet just reboots.
If I try "busybox ifconfig wlan0 hw ether ..." the address doesn't change(checked it).
Is there a WORKING method to change my MAC?
If you are wondering I am running the latest version of CM11
Bad bad bad

The Question is Why do you want to do this. You know the MAC address is like a serial number to your WIFI Device in the Tablet.If you Change this to match a wifi address to Anyone on the same WAN. The two devices will Conflict and Likely Cause the WAN Provider (cable company) to BAN BOTH MAC Addresses. They do this to STOP Theft of Services.
I Seriously ADVISE Leaving it be.
If you have a issue that you think changing the MAC Will help please post that issue and someone may be able to help..
Hey,
I know it's possible and I've tried several apps including 'MacChanger'.
If I change it and view my mac address, it's changed.
If I connect, it says 'Connecting...' for a long time and stops after a while, resets the mac address back to it's default and successfully connects.
Yes the MAC Address is in the right format.
I rooted my phone (Huawei Y550) manually with SuperSU and busybox installed.
Using ifconfig command on the wlan0 interface it doesn't change at all,
and I guess MacChanger uses the method that edits the file containing the MAC Address, which it shows the new mac address, but changes it to the default after connecting.
Any advice?
Thanks.
