Openvpn update for desire + tun.ko

Copy the update to your sdcard and apply the update with the recovery-console (sudo ./step2.sh from latest method)
You need OpenVPN Settings from the market (Friedrich Schauffelhut) and load the module from the following location: /system/lib/modules/tun.ko (see attached screenshots).
There's a different kernel in Modaco Custom Rom so we need a new module version. (2.6.29-82821fb5).
Openvpn from MCR kitchen lacks some cypher-algo's so i couldn't use that.
I left the busybox binary out in the MCR version.
If any of you have dns problems please use the "OpenVPN settings" provided setting for that:
Long press your connection config and change the Preferences.
happy tunneling.
HTC Desire stock kitchen = vpnupdatedesire_2.6.29-97da29ed-signed.zip
MCR kitchen (dont use openvpn from kitchen) = vpnupdatedesire_2.6.29-82821fb5-signed.zip
uvoc version = vpnupdatedesire_uvoc-signed.zip

Can I use the file and method to put tun.ko in system folder as required from vpnc?
Thanks

The file tun.ko wil be copied to /system/lib/modules/ if you apply this update. Don't know if vpnc can load the module or that you need to load it before you start vpnc (OpenVPN Settings can load the tun module on startup). You could always load it from commandline: adb shell insmod /system/lib/modules/tun.ko

vpnc works
I can confirm that vpnc works OK with this tun.ko module. Thanks Richard.
For the moment the get-a-robot-vpnc application does not work out-of-the box on Desire, but this is another issue.

Thank you. I've seen it and already tried, it works perfectly! Now I can use Rdp client. The Android one is so much better that the windows mobile's one!

Works perfectly, thank you.
Note to anyone who comes here, if you get an error about being unable to allocate the TUN/TAP device dynamically, it's because the insmod changed but the app. doesn't warn you. Check the paths and/or insmod manually to fix.

There's also a new openvpn + tun.ko version for the Modaco custom rom r1 kitchen online.

Should busybox be included inside this openvpn update too?

the modaco rootedupdate.zip doesn't provide busybox. Just to make sure i put it in.

There's a new version for MCR without busybox binary. See first post.
Tested on MCR3 and working without any problem.

New version for uvoc kernel posted.

I get the error you mention in OpenVPN Settings, but I am not sure I understand what to do. Can you please be a little more specific.
When I try to load the module in terminal I get this error :
insmod: init_module '/system/lib/modules/tun.ko' failed (Exec format error)
Thank you.

Sorry, changed = failed (must've typed on the Desire with auto-correct kicking in).
Try and insmod it manually
Code:
insmod /system/lib/modules/tun.ko
as root. If that fails, check it's actually there.
If all else failed, extract the tun.ko from the zip, push to sdcard and run
Code:
insmod /sdcard/tun.ko

What rom are u using? It looks like a wrong module for your kernel version.

hi richard,
yesterday i flashed r4 modaco rom on my desire and have seen that they use 2.6.32.15-g99cb4fa kernel version. can you provide a tun module for this ver?
many many thanks

[Q] Cisco AnyConnect for Rooted Devices

Has anyone got the Cisco Any Connect for Rooted Devices App to work on the TF??? I keep getting the "This device does not meet minimum requirements to run this software (TunTap driver could not be located)" error. Anyone find a workaround?

I'd root my TF in a sec if it will work. I've been trying to get this to work on my D2G but it also doesn't have a TunTap driver. I found tun.ko in one of the forums but have to had the chance to see how one might install it. I know some custom ROMs have it included.

works fine rooted prime + clemsyn 16

It seems that it is not able to load the tun.ko if it is present as a module. I had to use insmod /system/lib/modules/tun.ko to make it work. I have a stock kernel with just added tun.ko module.

Woah, didn't know this came out...thanks. Will give it a shot.
Edit: Appears to work fine, but I need get get my ASA license.

Awesome! Finally!

The app installs fine but when you try to connect is when you get that error. @ljs_cz, does the stock 3.1 come with the tun.ko module? If not where can I find one? I found a post with a module but its for 3.0.

Totally wasn't aware this existed. Works flawlessly on my TF running prime and clemsyn. This combined with RemoteRDP means I don't need to carry round my laptop when I'm on call!
Thank you OP, life-changer.

For those who are on stock 3.1 root, copy tun.ko to /system/lib/modules and
install it from a terminal, command "insmod tun.ko".
Check with command lsmod, you should see tun.ko loaded.
Install cisco anyconnect for rooted device and you are set.
Note, you will need to load tun.ko again after a reboot.

Thanks ill give that a try!!!

Ok its works great but when i restart the device the module isn't installed anymore and i have to insmod again. Any way to keep is installed after device boots???

i tried copying the tun.ko to /system/lib/modules but i got Permission Denied.
Is there another way to make this work?
I am rooted with build model 8.4.4.11

You need to mount the /system as RW before you can copy it. I am not sure of the ADB command, but you can do it through total commander (file manager) which is how I did it.

is it possible that you could give me a step by step guide as to how to accomplish this? i am trying but seem to be failing.

Bump, I could also use some help with ssretz's problem.

hmm..on ICS, tried your solution anyway. copied the file over to the location you specified, but when i run the command in the terminal it says no such file or directory.
Edit...i ran su -c insmod /system/xxx/xxx/tun.ko
i ran su earlier, but not on the same line.
that seems to register it. will test later.

still failing to copy files
Hi,
im running the TF PRIME 2 with ICS 4
im trying all of the suggested aboe and still failing to copy a file to the system/library/modules folder
any help?
i think it's a permission issue, my device IS rooted and i CAN copy files to the other SD folders

I've done it via command line (you must mount the system directory in RW mode) using multiple iteration of the proper switches until it finally worked, but if you're struggling, just spend a couple bucks to buy Root Explorer. The aggravation you'll save will be well worth it.
Root Explorer has a button that will eliminate the command line instructions necessary to mount the system directory in RW mode and return it to R only, along with allowing you a simple copy/paste interface to move the files.

connects but does not route over tunnel with CM9/Megatron 1.0.1
Current system with issue: Megatron 1.0.1 with stock kernel.
Details:
I am able to connect using Rooted anyconnect, and I see my route table getting updated but when I try to access a resource on the vpn network it can not reach. I am not able to ping, ssh, rdc to any resource thru the tunnel. Local lan resources such as my own computer work fine or internet resources
I see the following interfaces get created after I connect:
-csctun0
-droptun0
My route table displays updated routes after vpn connects showing to use the iface of the cscotun0 for the resources that need to be routed thru. (192.*, 10.*, etc)
Funny thing is that I am able to use the stock 4.0 ICS and/or older honeycomb releases and it works fine. It's just with Megatron 1.0.1 or any CM9 rom. I tried using update-cm-9-20120329-NIGHTLY-tf101-signed.zip, still a nogo. Leads me to believe could be related to the CM9 trunk.
The logs between stock and CM9 flavored roms look the same on anyconnect. Nothing glaring.
lsmod doesn't show the tun module in as I believe now tun is compiled directly in the kernel (can someone confirm this?) (Running lsmod with stock doesn't show tun, nor in CM9/Megatron).
I love me some cyanogen and really like ricardopvz work especially the quick apps, but I need my vpn working for production support as its nice to work off the tablet when I am not near a computer.
Any help or direction will be greatly appreciated. Thanks in advance.

Confirmed that my problem only exists with CM9/Megatron roms
AOKP and stock based roms work fine. Any one else have this issue?

Anyone has cifsmanager working after updating to 3.2?

If so, please let me know what I need to do?
I have cifs.ko in system/lib/modules but the app has not been working since 3.2 update.

Just answering myself in case someone has the same question.
it seems multiple module loading is not working right in the CIFSmanager.
i needed to load cifs.ko and nls_utf8.ko together before mounting my network drives
before Cifsmanager can handle this automatically, but now on honeycomb 3.2, it seems nls_utf8.ko is not getting load
after I loaded that file manually via terminal, all network drives can be mounted.

Could you share the steps?
Thanks.

share the steps to get nls_utf8.ko loaded?
cifsmanager still seems to load cifs.ko fine automatically.
to load nls_utf8.ko before mounting any network drives:
1. Open up a terminal app
2. type: su root (then hit enter)
3. type: insmod /system/lib/modules/nls_utf8.ko
You don't need to do this if you don't have foreign characters in the files on your network drives (cifs.ko by itself will do)

[Q] CIFS Manager compatibility?

Just got my A700 and it appears the kernel is not CIFS-compatible. I understand there are modules which can be used with CIFS Manager to make it work with non-compatible kernels. Does anybody know if one exists that will work with the A700?

Funny timing, I was researching this last night! I ran out of time, but essentially if you grab the kernel source, you should be able to compile the needed module, which we can then load.
I'll update this post later this morning when I dig up that URL.
--
Here are the two sources that I was referring to:
http://facti.net/drupal/node/151
http://facti.net/drupal/node/150
These articles were written for the TF101, but with the A700 kernel source available (go to Acer's Support site), there's no reason anyone cannot do this as well.
I'm going to try and find some time tonight, but we'll see.

Is this something that requires recompiling the whole kernel, or can you load the module into CIFS manager separately? If you manage to compile the module, can you post it here?

If I'm reading/researching everything correctly, all we need is a cifo.ko module from our kernel source. You should not have to recompile and install a completely new kernel.
Work is really busy today, but I've already downloaded the kernel source to a machine at home. Hoping to get time tonight to get it set up and run some tests. I'll post updates here for sure.

Thank you. I'm sure I'm not the only one who would appreciate it.

Alright, please try this file.
I cannot test myself, since I have not yet rooted (another topic entirely). Please let me know if this works for you.

No joy. Stuck the file where it wanted it, but I'm still getting "no such device".

You're rooted, right?
Can you execute the following command, to "force" the module to be loaded?
insmod /system/lib/modules/cifs.ko
You can use either ADB SHELL or Terminal Emulator. Be sure you're root when you do this too (sorry, not sure what your current knowledge level is).

Thx for your effort. Unfortunately i get the following error:
# insmod /system/lib/modules/cifs.ko
insmod: init_module '/system/lib/modules/cifs.ko' failed (Exec format error)

Thank you for posting this. I think I might know what I goofed. Hopefully will get another one compiled and posted tonight.

when you compile the modules are they tablet specific? i tried the cifs.ko and md4.ko from the a500 thread in my a510, and they would load up fine with insmod, but when i used cifsmanager to mount a windows share, or tried to mount from adb shell, the tablet would reboot.

They are specific to the kernel source code, yes.
I most likely did not have the correct kernel configuration in place, when I attempted my recompile. But since I'm returning the A700, I didn't feel like delving into it further. The articles I linked to earlier should be a good start if you wish to give it a go.

Any idea how to make CifsManager work on A510?

CIFS

Probably a long shot, given that the Infinity hasn't been out long yet, but does anyone have a cifs.ko kernel module that can be used with CIFS manager?
I've tried a few I've found for kernel 2.6.39.4. So far, they either fail or cause reboot.
Currently using the latest OTA 9.4.5.22 with kernel 2.6.39.4-00003
Thanks!

hi!
same same TF700T behaviour.
Also looking for mk4.ko and cifs.ko files for Infinity.
Currently version I have: (not very optymistic
1. Terminal Emulator
2. su -
3. insmod /system/lib/modules/cifs.ko (or mk4.lp) = reboot :/

I know it's an old thread but accutally I'm on CROMI-X (last version) and with your kernel v2 or v3 cifsmanager seems to works well but the mount point folder are "empty" . Before on CROMI all was ok. I tried different manager and application.
