Hello!
I'm very new to the android os and owner of an infuse (android 2.2.1, kernel version: 2.6.32.9, froyo.uckd5) since a couple of weeks.
Honestly I feel a bit lost because I'm looking for a tun.ko module for this device and as far as I can see there isn't, at least for the production rom. All the tun.ko I found are compiled for kernel different from mine.
I really need openvpn and now I'm wondering if I should:
1) keep looking
2) figure out how to compile a tun.ko on my linux machine for the arm7 architecture
3) look at some modified rom with the module built in
Do you have any suggestion?
Thank you
Cheers

3) As far as I can tell, all of the alternative kernels have this module. The Infused ROM contains the Voodoo kernel, but I believe you can run the Voodoo or Infusion kernels on the stock ROM.
ok I see.
Could you suggest to me a starting point to deal with the custom roms?
I'm have a good experience with linux since years but not enough on smart phones and android in general.
For instance, is there an official website for Infused ROM?
Any tip is welcome.
Thank you!
@dventurin - I had the same issue. I have the Infused rom installed and it has the same issue. I installed SL4A and wrote my own scripts, the app is what's broke everything works at the CLI. I then used Tasker but I think you can do it with Gscripts as well build my own shortcuts. As for where to find the Infused ROM look in the Dev section here. There a several ROM's available but I've only used Infused.
@3GBeyotch
were did you get the Infused rom? Is there an official website with documentation? Honestly I don't feel comfortable when I have to use stuff found on a forum: how can I trust them?

If you want the Infused ROM, head over to the "Infuse 4G Android Development" forum....
http://forum.xda-developers.com/forumdisplay.php?f=1161
From there, you will want to look at 2 threads....
1. You need to root your device first. Check out the very first thread (entitled: [How To] Root the Samsung Infuse 4G) shows how to root your device.....
http://forum.xda-developers.com/showthread.php?t=1082247
(the second link under SOURCE: has a video tutorial)
Side note: When downloading Superoneclick, make sure to get the one that has the drivers included. Also, make sure your external SD card is unmounted!
======================
2. Next, you'll need to install the Infused ROM. Look at the thread (entitled: [ROM] Infused v1.5.0 - (06/18/11) - Faster and smoother than ever!), which has the instructions, etc, for installing the Infused ROM.....
http://forum.xda-developers.com/showthread.php?t=1105413
You basically need to root your device first, then install the Infused ROM.
As far as feeling comfortable with using the sources from the forum, you have nothing to worry about. In regards to the Infused ROM, gtg465x is the one who developed it. All you have to do is follow the instructions, and if you feel uncomfortable about doing one of the steps, ask someone here!
I've had the Infused ROM installed now for a few weeks, and I have not been disappointed! Hope this helps.
Open VPN on Infused ROM tun.ko problems?
Greetings! This discussion is about what I am trying to solve, so I decided to post here. I have searched and read other threads, but can not figure out a solution. I am a noob in this.
Anyway, I also would like to make OpenVPN working on my Samsung Infuse.
I have rooted it, installed the Infused ROM Version 1.5.3 (awesme!)
About Phone gives me the following info:
Firmware version 2.2.1
Baseband version i997UCKE3
Kernel version 2.6.32.9
Build number Infused v1.5.3
No the problem. I have openvpn installed with OpenVPN Installer. My config, key, certificate files are in /sdcard/openvpn folder. Everything seems okay.
When I try to connect to my router at home, however, the tun.ko module would not load. It gives an error. I even tried to load it manually from the Terminal Emulator (insmod /system/lib/modules/tun.ko) It gives me an error still. The module file is in the folder.
What am I doing wrong? Has anyone been able to make openvpn work on the Infused ROM?
I had the same problem on the original AT&T ROM, but that one did not have the tun.ko at all, so it was understandable.
I would appreciate any suggestions.
Thank you in advance.

out of curiosity, is there also a tun.ko in /lib/modules in addition to /system/lib/modules?

Man, my hat is off!
Indeed, there is one in /lib/modules and it did work when I tried to load it, instead of the one in /system/lib/modules/. Any idea, why the other one did not work? Not that it matters now.
Also, your signature says that you run Cyanogen Mod with Infuse. My understanding was that Infuse was not yet supported. Is it easy to install it? Any published instructions?
Again, thanks a bunch for the tip.

My guess is in your previous attempts to add a tun.ko module, you stuck one in /system/lib, or maybe gtg accidentally included some "cruft" in /system/lib that shouldn't be there.
As to CM7 - Right now it's a source-only unofficial build, links to the git repo are in the Development section. There are occasionally binary releases floating around, however not anywhere on these forums. Good things come to those who expand their horizons and do research.

It seems, you are right. /system/lib/modules/ has only one file in it and it is tun.ko. That one did not load. Must be some left-overs from previous reincarnation. The one in /lib/modules/ has lots of different *.ko files and tun.ko among them. This one loads just fine.
Again, thank you very much for your help.

By the way. Perhaps, I can get a bit more help with this. My joy was short-lived. My Infuse connects to my Tomato - no problem. However, it does not force traffic to the VPN tunnel. It is still using whatever service I connect: Wi-Fi, or Cell Provider's.
Any hints on how to fix it? I tried the "Fix HTC Routes" option in "OpenVPN Settings." No luck.
I would appreciate some help.

Unfortunately someone else will have to help you there - I haven't used VPN functions on my phone.

Hi!
I would like to establish a Cisco IPSEC-connection with my Xoom, using get-a-robot-vpnc. The problem is that I'm missing a tun-kernel-module and can't find one for the xoom on the web
Does anyone have one for the Xoom WiFi only running 3.2 (Build HTJ85B) with stock kernel?
Thanks!

Pulled this out of the EU32Update file, not sure if its what youre looking for??

Thanks, I tried this but it looks like it's only for that ROM.
Maybe someone else has a tun-kernel-module for the stock 3.2?!
Greetings

yup, I'd like to see this too..
Just instal tiamat kernel 2.1 it contains tun.ko and several other modules.
http://forum.xda-developers.com/showthread.php?t=1200063
also you need to use this modified vpn connections
http://forum.xda-developers.com/showpost.php?p=12124163&postcount=23
Here is tun.ko for 3.2 stock.
wonderful! many, many thanks.
hi,
Will this work on 3.2.1? I copied it /system/lib/modules but when I try to openvpn I get cannot allocate tun/tap dev dynamically.
Is this just a bad file for 3.2.1 or am I missing something else?
I did install busybox and openvpn.
Thanks,
Your tun.ko kernel module needs to be compiled specifically against your kernel source. I don't work with stock anymore, however the developer kernel now floating on xda have this module specifically rolled into their kernels. You would have to root however to install these kernels.
Thanks Kevdog..
I searched and i couldn't find any for 3.2.1. I am the rooted stock 3.2.1 already downloaded from xda. Just need to tun.ko for 3.2.1.
If u know where to find, please send me the link.
Thanks.
Ok 3.2.1 -- Stock or Rooted? What kernel are you running?
I got my rom from this thread
http://forum.xda-developers.com/showthread.php?t=1278214
Thanks,
Ok -- I know this is a lot of work, however I tried it myself and I'm not sure if the rom you linked to is corrupted or my download process failed. (***Rant -- why all the developers who put out files don't match the file to an md5 sum so us users can verify the integrity of the dowload -- I'll never know!!), but I can't seem to extract your system.img. You'll need a tool such as unyaffs to unpack the system.img and then search around in the modules folder until you find the tun.ko. Or you could just flash a Tiamat 3.2.1 kernel which has these modules built in!!
I checked checksum and it was correct before I installed it. Not sure what u mean, I thought this rom doesn't have it period.
I also tried to use tiamat 2.2 which says its for 3.2 but it got stuck at boot for 30 minutes at the honeycomb screen. I thought maybe tiamat ker
Net doesn't support 3.2.1 yet.
http://forum.xda-developers.com/showthread.php?t=1200063
As far as i know this is latest. Doesn't mention 3.2.1. Didn't work for me.
I don't want to go to tiamat rom to avoid a full rebuild.
I have been recently trying to get OpenVPN to work with my Samsung Galaxy S 4G t959v.
One of the problems I ran into was the lack of a tun module (tun.ko?). So I proceeded to install the Bali v3.3 Kernel by Dr. Honk.
http://forum.xda-developers.com/showthread.php?t=1080871
After I flashed my android with this kernel. I double checked to make sure it worked and sure enough the kernel version was the new Bali Kernel. However, I still didn't have the proper TUN Capability that it specifically lists as a feature in the kernel.
I was wondering, did I actually install the Bali Kernel unsuccessfully but it just said it was actually in the system. I checked in lib/modules and tun.ko was not to be found.
(I came to the conclusion I needed this module through the error that I was receiving from OpenVPN and quite a few google searches of it: "FATAL:Cannot allocate TUN/TAP dev dynamically")
Anyway, I did all sorts of stupid crap to try and make it work, but I still can't find a way to do this. I'm under the understanding I can't really take a tun.ko file from another kernel (At least that is what I have read, but I may just be flat out wrong). Does anyone have any ideas?
Apologies for the long post, however I at least used some proper english!
I just installed ICS and it works fine. I never expected it to work as well as it does, but now I can get down to griping about little things that I use that don't yet work
Normally I use CIFS (Common Internet File System, like Samba was before) to access shares on the net. This worked fine on HoneyComb because I built my own kernel modules.
For ICS, I think the source is not yet released for the kernel. I did see that there was a tun.ko and cifs.ko for ICS over in the transformer prime section of XDA, so I tried those out but it appears the tegra 3 kernel is too different for these to work. (although I think the version is the same).
If anyone has seen or has a working cifs.ko module I'd appreciate getting ahold of it (or especially the ICS kernel source code).
Thanks -
I don't know about cifs.ko as I don't use it, but I do use OpenVPN and found out that tun is part of ICS now, you no longer need a separate module.

I didn't have much success with tun and cifs for my purpose which was to wirelessly access the sd card of the phone/tablet vice versa until I used the Samba app fom the market. In combination with Ghost commander and after upgrading to ICS everything was intact. Not sure if this is helpful to you or not. Just throwin it out there.
Thanks both of you -
I realized that tun was there but thanks. As for cifs, I suppose the module isn't really needed except to use certain utils that rely on it, like root explorer.
I found a number of samba/cifs compatible file managers that're fine for me like ES explorer etc.
Those will be fine and I'll look forward to getting kernel source for ICS anyway.

I've just rooted my TF101 (ICS) so that I could get Junos pulse working with its ssl vpn. Doing a bit of reading I found I needed tun.ko (at least with 3.2). That automatic tun.ko installer from the market reports that tun.ko is installed (compiled into the kernel?)
I can see the tun0 created, with an IP address. But it doesn't work, not a single bit travels the tunnel interface.
I'm officially confused...
Still too few posts under this account name to be able to post links, but have you seen this thread in Dev?
xpad / cifs modules for stock kernel ICS v9.2.1.11
Thanks for that... that confirms tun.ko is built in, which doesn't help me find/fix my problem.
Will keep at it!
I'm trying to get Ubuntu installed on my phone using the chroot/vnc method. Please don't refer me to the official Ubuntu for Android page.
The issue I'm running into it seems is that the kernel on my ROM (Glorious Overdose with Platypus Egg Kernel) does not support loop device, so I've hit a wall.
If there is a kernel available for our phone which does support loop devices a link would be highly appreciated, since it seems that virtually all of the existing links to ROMS, kernels and mods are 404ing.
This kind of sucks because my last phone, an LG Optimus was able to run Ubuntu, but it was too slow to really be useful. I'd really like to be able to get more out of my new Sidekick.
bump. Seriously, not a single response? Stock kernel doesn't have it. Bali kernel doesn't have it. Platypus Egg Kernel doesn't have it. Any way to incorporate it into the kernel?
This may be the wrong place to ask, but how does one go about building/modding an Android kernel? I've compiled Gingerbread to run on a netbook successfully before and I've modded the regular Linux kernel (added drivers for odd hardware, etc) many times before so it shouldn't be that different. Maybe it's time to get into ROM cooking.
Download the source from opensource.samsung.com, extract the ramdisk from a working kernel, rebuild with whatever changes you want.
As of now, no kernels that are released for the Sidekick include loop support.
Noob-un-2: I took a look again at this, and found that loopback is already enabled, but the mount is an actual binary, rather than being linked from busybox. you should be able to mount an image to a dir through loopback with the following command:
busybox mount -o loop /sdcard/myimage.img /mnt/mount_dir
(assuming that /mnt/mount_dir already exists, if it doesn't, create it).
