OpenVPN with Root - Updated 8/19

Easy way - OpenVPN on rooted/S_OFF Incredible with BusyBox installed:
This is by far the easiest way to set up OpenVPN. Make sure you copy your config file and any relevant keys to a folder on your sdcard. First, you need to know where BusyBox is installed, and if you already have the tun.ko module. For BusyBox, for most Roms based off the 2.2 8/1 leak, the location is /system/xbin. An easy way to check on your phone:
adb shell
find / -iname "iptunnel"
The path containing the file is where BusyBox is installed. If you don't have it installed, you can follow the instructions at the bottom of this post to install it.
The tun.ko module depends on your kernel. With the hydra 2.2 kernels, the location is /system/lib/modules/tun.ko . Easy way to check:
adb shell
find / -iname "tun.ko"
If you do not have tun.ko on your system, then you can download it for 2.2 (tun.zip) or 2.1 (inside openvpn.zip) attached to this post.
Next, download the following two apps from the Android Market:
OpenVPN Installer
OpenVPN Settings
Next, run OpenVPN installer, click install, give it an install path (I prefer /system/xbin), and give it the path to BusyBox.
Finally, run OpenVPN Settings. Go to Menu -> Advanced, make sure "Load tun kernel module" is checked.
Click on "TUN module settings"
Change "Load module using" to insmod
Change "Path to tun module" to... the path to your tun.ko file. Click back.
Update "Path to configurations" and "Path to openvpn binary".
That should be it!
This is how to run OpenVPN on a rooted Incredible using unrEVOked root and the stock 2.1 ROM with S_ON
NOTE: This is only for rooted Stock 2.1 without S_OFF. If you have S_OFF via unrevoked forever, just use Openvpn Installer and Openvpn Settings, both available in the market. Much easier!
This is my first time doing something like this, so bear with me if it is a little rough!
You must have root access to set this up. You do NOT need to go back into recovery adb though.
First, download the attached openvpn.zip containing the following:
tun.ko - kernel module for 2.1.
openvpn-static - statically compiled openvpn
If you are using 2.2, tun.zip contains the module compiled for the 2.2 kernel (thanks Apalyan!)
You will already need to have a working client.conf, and any associated keys. Copy the following files into a folder named 'openvpn' on the sdcard, or push with the following:
adb mkdir /sdcard/openvpn
adb push tun.ko /sdcard/openvpn/tun.ko
adb push client.conf /sdcard/openvpn/client.conf
adb push client.key /sdcard/openvpn/client.key
adb push client.crt /sdcard/openvpn/client.crt
adb push ca.crt /sdcard/openvpn/ca.crt
adb push openvpn-static /sdcard/openvpn/openvpn-static
The following must be done in a root shell:
adb shell
su
mkdir /data/openvpn
dd if=/sdcard/openvpn/openvpn-static of=/data/openvpn/openvpn
chmod 700 /data/openvpn/openvpn
Use the OpenVPN Settings configuration below to start/stop openvpn.
Note: All of the code was already written and ported to Android by the guys behind OpenVPN Settings. I just compiled a new tun.ko from the Incredible kernel source, and recompiled the statically linked openvpn with updated paths to ifconfig and route.
ADDED (thanks wraithdu!):
If you have trouble with post-connection routing, you may need to install busybox for a more powerful route/ipconfig. Instructions are here:
---
busybox is installed by the latest rooting process, but it's not a full install, ie it does not create all the command links. I got the file from the Titanium Backup site:
http://www.matrixrewriter.com/android/files/busybox-1.15.3.zip
To install:
1) extract and push busybox to your sdcard, reboot into recovery
2) mount /system
3) if you don't have /system/xbin (you should), create it
adb shell:
# mkdir /system/xbin (if necessary)
dd if=/sdcard/busybox of=/system/xbin/busybox
cd /system/xbin
chmod 755 busybox
./busybox --install .
4) reboot and done
OPTIONAL - before rebooting replace the busybox installed by the root process in /system/bin
1) mv /system/bin/busybox /system/bin/busybox.bak
2) cp /system/xbin/busybox /system/bin/busybox

OpenVPN Settings Instructions
OpenVPN Settings v. 4.6 works flawlessly with this! Here are setup instructions:
Install OpenVPN Settings v. 4.6 from:
Can't post links yet, do a google search for OpenVPN Settings, go to the Google Code download page, and download version 4.6.
Then, launch OpenVPN Settings, press Menu -> Advanced, and fill in the following settings:
Load tun kernel module - Checked
TUN module settings:
Load module using - insmod
Path to tun module - /sdcard/openvpn/tun.ko
Path to configurations - leave default
Path to openvpn binary - /data/openvpn/openvpn
It should work beautifully then.

any way to do it with non certicate based connections? i.e., group/psk configs?

The certificate setup isn't important, it is just how mine is set up. Any valid .conf should work.

ifconfig error
i got it all installed , it connects, but then in the end it says fatal error, ifconfig failed, could not execute external program. any ideas

You can run it manually to see what exactly is happening. Try the following:
adb shell
su
/data/openvpn/openvpn --config /sdcard/openvpn/client.conf
What generates the error?

and ifconfig is under /system/bin not /system/xbin/bb/. do you guys know where i need to change that?

The ifconfig stuff is hardcoded. I uploaded the wrong version - try this one.

Works perfectly
THANK YOU , works great

Thanks very much for this! Will be trying it later today.

Fang - Thanks again. Do you have any suggestions on a util or tutorial on making a conf file? I've access to our Cisco ASDM for our ASA, the URL for the ASA, group name, Group key, and of course my username and pw.

For that, you need vpnc instead of openvpn.
I know the problem with using the VPN Connections app is that the tun.ko autoload doesn't work. There are a couple of things you may be able to do as a workaround.
1. Load the module by hand:
adb shell
su
insmod /sdcard/openvpn/tun.ko
or 2. Use the OpenVPN Settings app from above to load the tun module (just start openvpn, then stop it), then try out the VPNC app.
I don't have a Cisco vpn so I don't have any way of testing whether this works.

Gets "failed to connect" immediately. know of any way to launch the vpn connections via command line to see where it is failing?

This worked like a charm! Thanks very much for this guide.

Stupid question, how do I get to a adb shell? I already rooted the phone. I don't have to do the rooting process all over do I?

If your running Linux, just type "adb shell" in you terminal window - make sure your phone is connected via USB cable - you should get the "$" after this command and then your in your phone's shell.
I believe windows is the same way, but I only have Linux stuff running now...

Thanks a lot for putting this together!

With the phone connected via USB (Disk drive or anything), I type "adb shell" and get device not found. I'm running Windows 7. Phone has been rooted (have Wifi Tethering installed). Just having issues getting it back to the shell command like when I first rooted it :/

make sure USB Debugging is enabled

OK, had a misspell in the tun.ko file.
I'm connected now. But unable to connect to anything on my network. Still looking into it.
Any ideas? I've restarted the phone. I'm connected to my OpenVPN server. I cannot ping the IP assigned to it (from OpenVPN status page). I cannot ping anything on my internal network from the shell. Shows no data moving. Do I need to do something?
I did a netconf and i have this:
tap0 UP 172.30.100.255 255.255.0.0 0x00001043

Ettercap for Android ARM

Hi guys, just to let you know, i successfully compiled ettercap for android!
This is a command-line tool only(for now) so if you never used ettercap, try it first on your PC.
What is working now (that i've tested):
- Text only support
- ARP spoofing
- ...
Not Working:
- Plugin Loading (should be easy to fix)
- Curses (is it really necessary?)
Sample usage on my galaxy S:
Code:
./ettercap -i eth0 // // -qT -M ARP
Now, use with care
I'd appreciate if someone write a how-to for "non-geeks", and a better mirror.
Download 0.11
Mirror (courtesy of a1Pha)
Cheers

How did You do that?

Hi,
How did you cross compile it, and did you upload the diff back to ettercap project ? They would benefit from the changes.
I did the following to get it to work so I could execute the file from the sdcard.
# mount -o remount,rw,dirsync,nosuid,nodev,exec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro -t vfat /dev/block/vold/179:1 /mnt/sdcard
# ./ettercap -i eth0 // // -qT -M ARP

Can you reupload the file. Thanks.

Link updated.
There is only one line of code modified from the original project, which sets the uid and gid to another than root, and prevents ettercap from working correctly, so i commented it and now it works well. Later ill make a tutorial on how to build it.
Cheers

Great work onaips. But how to install it? Do you have any guide ready?
I can not find out a way to install it.

Great job here, I use Ettercap on my laptop pretty frequently, and have been waiting for an Android port. The only problem is that I keep on getting a permission error using my personal terminal emulator.
After getting su permissions, I type:
# ./ettercap -i eth0 // // -qT -M AR
Then, it just spits out:
./ettercap: permission denied
Any thoughts?

Try to give it executable permissions,
chmod 777 ettercap

No luck, but thanks for the suggestion. It still gives the same permission denied error. None of the other files in the folder have permission as well, not even with the chmod command.

Still no luck with the plugins? Can someone help?
@skafan2 you probably are trying to run it from your sdcard, on a fat partition. Try to move it to the /system directory, or any other place formatted as ext-*

Hey.... Many many many thanks, but i have a question..
i run debian-ubuntu-bt5 on my HTC DesireZ and i can not run ettercap because of some Fatal error with the Layer 3 (wich is the internet layer). Then, i was suspicious with the interface (eth0). Eth0 refers to ethernet connection and i am connected wireless (is this the problem)????? i tried to change my eth0 interface with the wlan0 but without luck.... please help me how to make it work....
Thank u again

thank you!

ettercap layer 2 error
come on guys please someone answer me, i really need this to work

dude on most mobiles wifi= eth0 or tiwlan0 so quit trying to change it to wlan0. Also, are you talking about the android ettercap binary or the debian chroot version? also post exactly what it says if you can

working but not package received, cant put in promicious mode...

Hi, the binary is working but is telling me 0 plugins, any one knows how to deal with the plugins

links dead
Both links are dead. Can you fix it?
You can mail me the app, i can mirror it for you if you'd like.

Reup please ....

Jah. reup please

I'm also interested in testing this on an android phone, but the links are dead.

OpenVPN on Defy

hello..
i've been trying to get openvpn to work on my Defy but no luck so far.
what i've done is:
-install busybox
-install openvpn settings and installer
-found my tun.ko
-copied my openvpn config to sdcard
-changed openvpn settings
-the vpn tunnel is created and connection is made but traffic doesnt seem to be routed to the tunnel
did anyone manage to get openvpn to work on Defy?
it was working fine for me for different android devices.
i used this tutorial:
hxxp://www.android-hilfe.de/root-hacking-modding-fuer-motorola-defy/58423-openvpn-auf-dem-defy-2.html

I use the phone's own VPN settings under Wireless & Networks and manage to get things working without any problems.

this is for PPTP or IPSEC but not OpenVPN.

Ohhh.... Good i found this thread, maybe you guys will be able to help me...
I have a working VPN connection from for ex. my laptop > home (PPTP)
But i am unable to connect to it using Defy's original VPN connection...
I get:
"Unable to connect to the network. Do you want to try again?"
Also - what does mean this "DNS Search Domains " setting?

what ROM are you using? on 2.2.1 L2TP works fine but not PPTP.
your options:
1. try L2TP or L2TP/IPSEC if your provider supports it
2. if your on a 2.1 ROM, try a 2.2.1 ROM
as for DNS search domains, you can put google's for example 8.8.8.8
or leave it blank if after connection is successful you can browse without problems.

Im on 2.1 - so its just that that on 2.1 PPTP is not working?
So DNS search domain are just specifying the DNS'es you will be using on this connection?

1. Yes, at least for me.
2. correct

does anyone here still need help with openvpn?
i managed to run openvpn through a dns tunnel over a public hotspot at the airport.
this works on most of the newer (hotspot)systems but is extremely slow.

i got it working, i will post the steps later on.

Found the solution! here u go!
1. install openvpn-installer
2. Run openvpn-installer and during installation point to busybox (ifconfig/route) at at /system/xbin/bb
3. create the directory at /system/xbin/bb
Code:
mkdir /system/xbin/bb
4. Make symbolic links to ifconfig and route
Code:
ln -s /system/xbin/ifconfig /system/xbin/bb/ifconfig
ln -s /system/xbin/route /system/xbin/bb/route
enjoy~!

1) Install busybox using busybox installer from market, choose to install busybox in:
/system/bin
(dont install in /system/xbin , if already installed, please delete route and ifconfig in /system/xbin first very importanttttt)
Install Openvpn from Openvpn Installer in /system/xbin
using root explorer or whatever you use, replace openvpn binary with this:
http://github.com/downloads/fries/android-external-openvpn/openvpn-static-2.1.1.bz2
dont forget to change the permissions
using adb or terminal emulator:
Code:
su
mount -o rw,remount /dev/block/mmcblk1p21 /system
ln -s /system/bin/route /system/xbin/route
ln -s /system/bin/ifconfig /system/xbin/ifconfig
mkdir /system/xbin/bb
ln -s /system/xbin /system/xbin/bb
use openvpn settings to set your options (insmod for tun.ko, tun.ko location, openvpn location)
my main problem, which i dont know why, was because busybox is installed in system/xbin, while it should be installed in system/bin and then using symlink to system/xbin
anyway it works for me now, let me know if it does for you.

did you install busybox to /system/xbin/?
did you create /system/xbin/bb? and symlink route and ifconfig to that folder?

i hope you guys can post step by step tutorial here .. this is my first android phone ...
thanks !

CIFS Manager on CM 7

Here is what I've tried:
1. Settings -> about tablet to get kernel version: 2.6.32.39-cyanogenmod [email protected] #1
2. Go to http://droidbasement.com/db-blog/ and find the kernel for gTab. There are several one, I just picked one with Gingerbread and downloaded
lib-2632.39_gb.tar.gz
Unpack on put cifs.ko under /system/lib/modules
3. Install CIFS Manger
4. Run CIFS Manager, add the share
5. If there is problem mount it in rw mode, use option "rw,noperm" (thanks, rajeevvp)
The share is successfully mounted.
Thanks!

After pushing the cifs module to the tablet you need to add an chmod and then you also need a insmod line every time you want to use it (at least after following a reboot).
Go back and read the instructions on droid basement. He has the details of the steps following loading the cifs.ko.
Good luck.

CIFS manager already loads the module fine. Are you saying in order to mount in rw mode, it needs permission on cifs.ko file?

No, you don't.
CIFS Manager should have an option to do a read-write mount.
Otherwise, you can try changing the mounting back into read-write mode:
Code:
$ su
# /system/xbin/mount -w -o remount /CIFS/PATH
Replace, /CIFS/PATH with the directory you provided to CIFS Manager.
Also, understand my cautions, as mentioned in the other thread, about mixing and matching kernels and kernel modules. I would suggest that you also install the kernel that goes with the module file you downloaded--ie. get the one in the same blog post.

Appreciate your advice on not mixing kernel and modules. I could not tell which exact build CM 7 uses so I had to pick one. When I get more experienced with Android, I may start changing kernels.
Doesn't CIFS uses rw mount by default? If not, what's the option? rw? I've tried that as well.
If I change the system file to mount it by default, I'd have to save the password on the command line, right? Will wireless be ready at that time? And if server or wireless is not ready at the time, I'd need to manually remount with some tool, do I?
Thanks!

Yes, by default it should be mounted read-write. If, for some reason, it gets mounted read-only, you can use the remount command I gave earlier to make the mount read-write again.
But, there could be other reasons for you not being able to write to the share directory. Permission and UID/GID mismatches could be one reason. Try adding the "noperm" flag to tell Linux not to check permissions locally ie. do the permission checking only on Windows:
Code:
/system/xbin/mount -t cifs //SERVER-IP-ADDRESS/SHARENAME /some/path -o rw,noperm,domain=DOMAIN,username=USER.NAME,password=PASSWORD
If I change the system file to mount it by default, I'd have to save the password on the command line, right? Will wireless be ready at that time? And if server or wireless is not ready at the time, I'd need to manually remount with some tool, do I?
Click to expand...
Click to collapse
Which system file? If you mean /etc/fstab, then that file does not exist on Android.
CIFS Manager (I haven't used it) should have an option to let you store the password securely. On normal Unix systems, the mount command accepts a "credentials=/some/file.txt" option which can be used in place of the "domain=XXX,username=YYY" options when mounting. Unfortunately, the mount command on the gTablet does not understand that option--I checked: you have to do it the old-fashioned way. You can't even skip the "password=" bit. On Unix, if you skip that, the mount command will prompt you for the password.
The solution, if you don't use CIFS Manager, is to place all the commands--the insmod and the mount--into a shell-script and give it 700 permissions. That way only the owner can see what's inside it and you can run the script after the wireless has come up.

noperm does the trick. Will update first post.

Could you explain the exact process for doing this from a terminal emulator. My main hold up is the /system directory being read only, so I can't copy the module (CIFS.KO in this case) to that directory.

You don't need to put cifs.ko into /system. If CIFS Manager asks for the path to a cifs.ko file, then you can put the file anywhere you want.

I have a new problem. There seems to be a limit on the file size. I have a 3 GB file shows up as 28 KB. Does anyone have success with large file? Thanks

I tried your instruction... there are two problems...(my rom is also cm7.0.3)
1. I can't put the cifs.ko into /system/lib/modules~ it seems that it is forbid to copy some files into system folder...
2. so I tried to put the cifs.ko in the /mnt/cifs.ko, and made the related setting in cifs manager(path to cifs.ko), then i mounted, but it showed that:"no route to host"
but i am sure that my ip and password is correct... so is there anyone know how to solve this problem?

I used Root Explorer. I am sure there are other means to put it under /system. I am not sure if that's necessary

I literally just went through this today. Download Terminal Emulator (free on the market).
PS: Don't type the '#' sign below.
#su
#/system/xbin/mount -w -o remount /system
#cp /SDCARD/cifs.ko /system/lib/modules/2.6.32.41-cyanogenmod/
#/system/xbin/mount -r -o remount /system
Then, just add the path /system/lib/modules/2.6.32.41-cyanogenmod/ into CIFS Manager. Should be all set.

File size limits depend on the underlying filesystem.
I tried the following command on an external NTFS formatted USB HDD connected to a Linux desktop mounted on the gTablet at /mnt/usbdisk via CIFS, and had no problems.
Code:
# ls -l /mnt/usbdisk/rvp/bak/hda3.img
-rw-rw-rw- 1 root root 8011422720 Apr 17 2010 /mnt/usbdisk/rvp/bak/hda3.img
# dd if=/mnt/usbdisk/rvp/bak/hda3.img of=/dev/null bs=1M skip=7500
140+1 records in
140+1 records out
147102720 bytes (140.3MB) copied, 150.135761 seconds, 956.8KB/s
The command skips the initial 7.5 GB of a 8,011,422,720 byte file and reads the rest (~140 MB).

not to confuse issue with whatop is having but I wonder if anyone has run into a problem with cifs in which it doesn't include all of the folders from your windows shares.

I had the same issue, but I found the guide on abettergeek which helped me fix it. Turns out the problem is that the mount point created by Cifs Manager doesn't have execute permissions.
I don't have enough seniority to post the link, but it's a recent post on abettergeek.com. If someone with enough seniority wants to paste it, some others may find it extremely helpful.

I have the same issue. I haven't tried this fix yet, but I will give it a go.

Pls, where I can put "rw,noperm" in cifs manager? I tried in module path as:
/system/lib/modules/slow-work.ko:/system/lib/modules/cifs.ko rw,noperm
And:
/system/lib/modules/slow-work.ko:/system/lib/modules/cifs.ko:rw,noperm
But still don't working as rw.

[Q] WiFi TXpower + iwconfig + tether + Bumblebee on LG OP V

This post is actually part HOWTO and part Question / RFC
Hardware used:
LG Optimus V
Software used:
Bumblebee ROM 2.4
WiFi TXpower
Wireless Tether (for root users)
iwconfig
UAPick (to change the User Agent string in IE8 to avoid raising red flags with Virgin Mobile)
So I've been playing around with OP V and decided that it would be best for me to reduce my wifi TX power since I always us my wifi tether is close proximity to my laptop. Unfortunately, the ROM that I use does not come with the iwconfig tool necessary so I had to do a little fiddling around to get everything to work. So I figured I'd post here so you guys can review what I did and make any corrections if you think there is a better way to do this. And hopefully this info will help out some people that are newer at this than I am.
After I installed Bumblebee 2.4, I decided to play with the Tether APP that comes with it. I configured BB's tether and used UAPick to change IE8's UA string to the UA string from the Android Browser. It then occurred to me that my OPV was sitting ~2' away from my laptop and didn't to be transmitting at full power. So I started looking for APP to easily adjust the TX power. I happened upon WiFi TXpower in the android market and installed it. But it did not work because the Bumblebee ROM does not come with iwconfig.....hmmm....what to do what to do?
After many hours of Googling and reading forums I came to find out that I needed access to iwconfig to make WiFi TXpower work correctly. So I had to make a choice, 1) try downloading iwconfig and try to adb push iwconfig to /system/xbin and hope it works and that I can chmod the file correctly 2) install and APP that comes with iwconfig and symlink it into the /system/xbin dir.
Fortunately, I stumbled on a post in a forum that stated the APP Wireless Tether (for root users) comes with iwconfig and it allows for changing the TX power level in the APP (for hardware that supports TX adjustments). So I installed Wireless Tether (for root users) setup my Android for wi-fi tethering. I then proceeded to fire up my laptop and put it in my bedroom with the android phone on my kitchen table in order to test changing TX power levels and checking the change with my laptop.....SURE ENOUGH IT WORKS. Power level changes supported by the APP are as follows: disabled(no TX reduction)/3mW/5mW/10mW/15mW/20mW/25mW/30mW. The only problem is that the APP is rather large. 403KB for the .apk and ~.98MB when running on the Android. So onto the next step.
WiFi TXpower is pretty light weight @ 92KB supports the following power levels: 4/11/18/25/32 so all I need now is iwconfig to get it to work right. I decided to symlink iwconfig from the Wireless Tether (for root users) install dir instead of trying to adb push it. Here's what I did to symlink:
# adb shell
# echo $PATH
# mount -o remount,rw -t yaffs2 /system /system
# ln -s /data/data/android.tether/bin/iwconfig /system/xbin/iwconfig
After that I fired up WiFi TXpower and now it works because the symlink worked. . I was just happy because it's been a long time since I made a symlink.
So now I would like some input form you guys here.
1) Is it possible for me to just unzip the Wireless Tether.apk and pull out the iwconfig then use adb to push the file into /system/xbin so that I don't have to install the whole APP package then create a symlink. If I do go that route will I have to chmod the iwconfig?
2) Could I just copy the iwconfig to /system/xbin from the install directory then uninstall the APP it came with.
3) Can I package the iwconfig (and possibly other wireless tools) into a zip that I can flash to the system from the Xionia recovery? This is how I would prefer to do it so that I have a simple package to load if I ever switch ROMs.
I'd greatly appreciate any feedback you could provide as to the best method and if I may have done this the long hard way or the right way. Although I am new to Android, I have been playing with linux on & off for the last 12+ years. It's just been ~2 years since my last outing with a full blown install that I could play with.

P.S. Thx to obijon for Bumblebee. I've been loving this ROM for the last couple weeks and having the Terminal Emulator app installed by default was VERY helpful to me in getting this WiFi TXpower / iwconfig thing worked out.

so this will work on p500 also?
should i type these in terminal emulator?
# adb shell
# echo $PATH
# mount -o remount,rw -t yaffs2 /system /system
# ln -s /data/data/android.tether/bin/iwconfig /system/xbin/iwconfig

1/ Flash this
2/ Use /system/etc/setwifi.sh script or WiFi Tx Power (the iwmulticall method).
3/ Done

k i will try..
im using void froyo final

To be 100% honest I don't know if it will work on other hardware, as I have only done this on my hardware. I guess you could always install the Wireless Tether for root users APP and conduct a similar experiment to mine, in order to verify that your platforms wifi radio can change TX levels. The thing I like about the WiFi TXpower app is that it can change TX levels on the fly and comes with a very simple widget that allows you to "single tap cycle" through the TX levels. Where as the Wireless Tether app shuts down the radio and tether to modify the power level.
So by using the WiFi TXpower app you can use your personal favorite wifi tether app and have the TXpower toggle/cycle seperate. And it even works when your using the WiFi radio for anything else since it runs as a service in the background and sets your specified power level whenever the radio comes on. Which is awesome when I'm at home or in a coffee shop with a good signal. No need to operate at full power.
You should definitely let us know if dr.notor's solution works for you. good luck man.

dr.notors method worked, thx anyway

no worries mate. that's why we post what we do. to help each other.
glad nortor's suggestion worked for you.

Talking about WiFi Tx power... what are recommended values for someone like me who use my home Wifi with a router on a small apartment?
LOL 1.4.2 Rom (which I use) has WiFi Tx set to 20 by default, but I've always wondered if that's already a "reduced value" or what. Does anyone knows what's the actual default value for The Optimus One?

32 dBm......

yep! 32/30 is the default.
I'm in a 750 sq/ft duplex and I go outside to smoke cigs (about 50+' away) and a setting of 4/11 dB works great for me. So you could drop it down a few levels and still maintain good connectivity. Judging by the the Windows Vista "WiFi power level meter", @ 4dB WiFi TxPower setting I still have 50% signal strength @ ~100' away on my HP Laptop's wifi card/antannae.
regarding dr.norto's setwifi.zip file: It's doesnt seem to like my Xionia/LG OPV. It gives me a "failed : no boot.img" error. So this .zip may not be for everyone. It may be an issue with the Bumblebee 2.4 rom or the Xionia recovery tool. Which is a bit of a bummer as I REALLY wanted to use iwmulticall instead of imconfig. But that is just how life goes.
I'm working on getting the Jave SDK & and Android SDK install and working so I can build a package for the LG OPV guys with either iwconfig or iwmulticall.
thx for all the help guys.

You can try to replace update-binary with one from some of the working ZIPs on your device. Other than that, no idea about your recovery. This works (tested) with CWM and AmonRa...

I'm having a ***** of a time getting iwconfig on my Asus transformer tablet. I tried flashing this, but didn't work. I'm running Xenogenesis JB 4.2. is there any way to get this working?
