Problems on Galaxy nexus

[Roberto Viti]

Hi everybody.

I got some problems while running OpenVPN Setting on my Galaxy Nexus.

I'm trying to connect my Nexus to the network at work, where we have an openvpn server running; when I try to run openvpn-settings the program quit with this error:

"Linux ifconfig failed: external program fork failed".

I've tried to find in the logcat output when the program stops, and it seems to be something around the ifconfig execution. If I try to run it from shell i got this output

"ifconfig: tun0: error fetching interface information: Device not found"

or a more clueless note:

"ifconfig: SIOCSIFADDR: No such device"

My goal should be start to work with tap interface, but i'm not even able to get a  connection with the tun... 

I even have checked out if my kernel got the CONFIG_TUN option setted, like it is. I don't know where to look anymore...

here comes my logcat with some mods for privacy reason...

Hi,

Please make sure /system/xbin/bb/ifconfig is a link to busybox on your
device.

Best Regards
Friedrich

Hi Friedrich,

I've checked out what version of ifconfig is pointed by /system/xbin/bb/ifconfig

shell@android:/ $ ls -l /system/xbin/bb/ifconfig

lrwxrwxrwx root     root              2012-11-15 16:33 ifconfig -> /system/xbin/ifconfig

shell@android:/ $ ls -l /system/xbin/ifconfig

lrwxrwxrwx root     root              2012-11-14 14:49 ifconfig -> /system/xbin/busybox

maybe he's not able to follow a double link. I've modified the link in this way and tried again

shell@android:/ # rm /system/xbin/bb/ifconfig                                  

shell@android:/ # ln -s /system/xbin/busibox /system/xbin/bb/ifconfig

And the result is... the same as before :( "Linux ifconfig failed: external program fork failed"

May depend on the version of busybox installed?

This is my version: http://goo.gl/lG7V1

Thank you for your patience!

UPDATE:

Hi everybody. 

For what i understand, openvpn can bring up a tun0, but fail to set up an ip.

I checked if ifconfig executed is the one of busybox (and it is), i even reinstalled openvpn several time but I'm still not able to execute it.

So i made a script to understand what happen during the execution.

#!/bin/bash

while true; do

  if /system/xbin/busybox ifconfig tun0 &> /dev/null; then

    # Found Tun interface           

    echo ""                           

    /system/xbin/busybox ifconfig tun0   

    # trying to set ip like openvpn                                                 

    /system/xbin/busybox ifconfig tun0 10.8.0.74 pointopoint 10.8.0.73 mtu 1500 2>&1

    /system/xbin/busybox ifconfig tun0

    echo "exiting..."

    exit 0

  else         

    echo -n "."

  fi

done

Unfortunatly this script is too slow to complete the execution between the bring up of tun0 and the crash of openvpn, but if you trust me this is the "combined" output obtained by executing this script several time and by commenting one "ifconfig" at time.

......

tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

exiting...

So, for what i can understand, ifconfig is working. Any hints?

R.

[Roberto Viti]

Problem (magically) solved!

I flashed a clean stock rom taked from Google, reinstalled Busybox and OpenVpn and then everything starts to work.

Maybe i do some mistaskes during the steps in the past ROM...

Btw, thanks for your help!

R.

[Friedrich Schäuffelhut]

Good to hear it works for you now.

Regards
Friedrich

Did you find a way to use tap dev with android?

[Roberto Viti]

Yes
To replicate my test you'll need just a rooted phone, a correct openvpn.conf and a working openvpn binary.
I've tried it only from an adb shell or by calling it from a self made app, but it works...
