-OpenVPN Client Support
-How to connect to OpenVPN server with Toshiba AC100? This method and all resources here is for original Android 2.2 (Froyo) on AC100 device.
-For OpenVPN client you need:
-- Rooted AC100 device
-- My boot image (part6-10W.img, mirror) with kernel compiled with tun device support and tun.ko module (mirror)
-- nvflash from linux4tegra package
-- adb tool (part of Android SDK)
-- abootimg and new zImage (mirror) (only if you need repack boot image, for other models than AC100-10W)
-- android-openvpn-installer and android-openvpn-settings apks
-## Boot image with kernel and tun.ko support (only for AC100-10W model!)
-Original kernel of AC100 doesn't compiled with tun.ko module. So I downloaded 2.2 kernel source codes (thanks to xandrster and his post) and compiled new zImage with tun.ko as a module. Every model of AC100 has different boot command line. I updated partition 6 (boot image) from my AC100-10W with abootimg, so users with AC100-10W model can flash my boot partition (part6-10W.img):
-- download part6-10W.img
-- goto recovery mode (hold down the CTRL + ESC/back keys and power on the device)
-- from linux4tegra/nvflash directory run:
-LD_LIBRARY_PATH=. ./nvflash --bl ../prebuilt/fastboot.stock.bin --go
-- don't forget backup your partition 6:
-LD_LIBRARY_PATH=. ./nvflash -r --read 6 part6-backup.img
-- install downloaded part6-10W.img
-LD_LIBRARY_PATH=. ./nvflash -r --download 6 path/to/downloaded/part6-10W.img
-- long press power button and then turn on
-## Update your boot image with new kernel (for all AC100 models)
-Because of different boot command line on every AC100 submodel, you need to update YOUR boot partition.
-- download zImage kernel
-- goto recovery mode (hold down the CTRL + ESC/back keys and power on the device)
-- from linux4tegra/nvflash directory run:
-LD_LIBRARY_PATH=. ./nvflash --bl ../prebuilt/fastboot.stock.bin --go
-- get your partition 6:
-LD_LIBRARY_PATH=. ./nvflash -r --read 6 part6.img
-- update zImage with abootimg tool (don't forget to make backup of part6.img before)
-abootimg -u part6.img -k zImage
-- install new part6.img to device
-LD_LIBRARY_PATH=. ./nvflash -r --download 6 path/to/downloaded/part6.img
-- long press power button and then turn on
-## tun.ko module and OpenVPN install
-- download tun.ko and place it to somewhere on storage (eg. /storage/openvpn/)
-adb shell mkdir /storage/openvpn/
-adb push tun.ko /storage/openvpn/
-- download and install android-openvpn-installer and android-openvpn-settings and install openvpn according to the manual. WARNING: because of ac100's incompatible version of ifconfig/route tools, it's needed to use busybox. You need to create /system/xbin/bb folder and symlink busybox to ifconfig, route commands:
-adb shell
-$ su -
-# busybox mount -o rw,remount /system
-# busybox mkdir /system/xbin
-# busybox mkdir /system/xbin/bb
-# cd /system/xbin/bb/
-# busybox ln -s /system/bin/busybox ifconfig
-# busybox ln -s /system/bin/busybox route
-# cd /
-# busybox mount -o ro,remount /system
-# exit
-$ exit
-In openvpn-installer select "/usr/xbin/bb" as your ifconfig/route bin dir.
-- put your openvpn-client.conf file with certificates to /storage/openvpn/
-- run android-openvpn-settings, in the Advanced settings check "Load tun kernel module" and TUN module settings chose insmod and "/storage/openvpn/tun.ko" as a path to tun module.
-- DONE. You can click to openvpn config file and connect.
