I just compiled a tun.ko and got OpenVPN working on the Tmobile Gslate! so I thought I would share:
1- Rooted (thanks to Chandon)
http://forum.xda-developers.com/showthread.php?t=1065882
2- Install tun.ko (Attached below)
download and unzip
Code:
adb remount
adb push tun.ko /system/lib/modules
adb shell
chmod 755 /system/lib/modules/tun.ko
Note: This tun module was built for kernel 2.6.36.3+
3- Install BusyBox using BusyBox Installer (from Market)
Install to /system/xbin
4- Install OpenVPN using OpenVPN Installer (from Market)
Install binary to /system/xbin
Install route to /system/xbin/bb
5- Install OpenVPN Settings (from Market)
6- Install OpenVPN static binary:
Download Static openvpn
Un-bz2 the file (7-Zip on Windows | bunzip2 on linux)
Code:
adb remount
adb push openvpn-static /system/xbin/openvpn
adb shell
chmod 555 /system/xbin/openvpn
7- Link Busybox ifconfig and route to /system/xbin/bb
Code:
adb shell
su
mkdir /system/xbin/bb
ln -s /system/xbin/ifconfig /system/xbin/bb/ifconfig
ln -s /system/xbin/route /system/xbin/bb/route
8- Setup OpenVPN Settings (from Market)
OpenVPN settings > Advanced > Load tun kernel module <- turn ON
OpenVPN settings > Advanced > TUN module settings
Load module using - insmod
Path to tun module - /system/lib/modules/tun.ko
9- copy your .conf files to /sdcard/openvpn
REBOOT
CONNECT!~
Extra for SMB mounters : Cifs.ko ! - Attached!
Edit: June 5 '11 - Extra for Asian users : nls_utf8.ko - Attached!
Well, I'm able to connect to my OpenVPN server now, but there must be something different in the binary..."client.conf: Connected" keeps spamming the notification area. Are you having this problem?
On a related note - I've got a couple other options, if I can get my cross-compiling tools set up correctly...I could use SonicWALL's NetExtender app, but that needs ppp_async and ppp_synctty built. I also wanted to be able to talk to a Windows-friendly PoPToP VPN server, but I suspect I'd need the ppp_mppe.ko built for that.
I tried compiling the whole kernel with the options I've mentioned, but I don't think I did it right...the make went all the way through, but I was using the gcc 4.4.3 eabi set in the SDK/NDK toolset. Since then, I've been trying to set things up according notes I found at K's Cluttered loft ( at triple-w dot (noob html limitation workaround) ailis.de/~k/archives/19-ARM-cross-compiling-howto dot HyperText Markup Language ) but start encountering problems when I try to build glibc...do you know of any instructions/tutorials which might help to educate this n00b (aye, that be me) in the fine art of ARM cross compiling?

Yeah I have that spamming problem too .. always have with the honeycomb tablets.
I used 4.4.0 eabi, and had to hard code the localversion in the setlocalversion file and absolute path to the eabi modules in the makefile to get it to cross compile
I built and attached the ppp_async.ko , ppp_synctty.ko , ppp_mppe.ko for you (I did not test a insmod as I built and tested the cifs and tun on a friends tablet - do let me know if these work!)
That's great! Thanks for putting those together. All of the modules you created insert fine with insmod (this version of busybox still has an issue with modprobe running on this tablet, suspect may be related to self-referring parameter, but hope to experiment more later) with the exception of mppe. That one comes back with "insmod: init_module '/system/lib/modules/ppp_mppe.ko' failed (File exists)".
This, however, may not be due to the module itself, strictly speaking. The other two, which are presented by SonicWALL as a workaround to their proprietary VPN app, inserted fine, but still produce an I/O error when a connection is attempted...closer inspection of the app's log reveals a similar complaint under the hood:
06-01 08:01:36.848 I/NetExtender.ppp( 8207): Nxhelper: start pppd main routine
06-01 08:01:36.858 D/NetExtender.ppp( 8207): using channel 1
06-01 08:01:36.858 E/NetExtender.ppp( 8207): Couldn't create new ppp unit: File exists
06-01 08:01:36.858 I/NetExtender.ppp( 8207): Nxhelper: pppd hung up, notify the service
My off the wall guess, pending further investigation, is that inserting mppe, or trying to initialize the other two, results in an attempt to create a device handle which is not being properly enumerated? ( i.e., attempting to create an instance of /dev/ppp, which already exists, instead of a new handle, say, /dev/ppp0, ppp1, etc.) Again, just theorizing blindly at this point - but you've certainly given me a great deal to work with, and I say thank ya big big.
I'll update you with any progress I make here, but at least for the time being I still have basic connectivity to one of my networks, and I can do much with that. And the cifs module works a treat as well!
In the meantime, a simple script allows me to toggle the VPN on and off without being annoyed by the spamming...then I add a widget to the script using ScriptManager (from the market) and viola! Look ma, no hands!
Code:
#!/system/bin/sh
BB="/system/xbin/busybox"
VPN="/system/xbin/openvpn"
TUNDTL=`$BB ifconfig tun0 2>&1`
RESULT=$?
if [ $((RESULT)) -eq 1 ]; then
$VPN --config /mnt/sdcard/openvpn/client.conf --daemon MYVPN
else
VPNPID=`ps openvpn | grep "^root"`
VPNPID=`echo $VPNPID | cut -d" " -f2`
if [ $((VPNPID)) -gt 99 ]; then
$BB kill -KILL $VPNPID
fi
fi
exit
(Just for anyone who doesn't want to wait until OpenVPN Settings gets a bugfix for Honeycomb. Obviously, adjust locations as needed. Oh, and don't give the script a name that starts with "openvpn"...unless you WANT a kamikaze script. This simple script obviously wouldn't work for multiple tunnels, (if they're even supported), but it does ya fine for the basic config.)
awesome idea for the spamming .. sadly I have 8 openVPN servers I switch between so i have to put up with the spamming.. any idea what the reason of the spamming is? maybe contact the dev?
The source for the app is available at 'code.google.com/p/android-openvpn-settings'. The issue has been reported already by a few people (issue 70), but it looks like there are quite a few other issues reported, so no telling if or when Mr. Schäuffelhut will have a chance to review it. It seems like it would be a good starter project for a would-be contributor...I haven't done any java developing, but it seems like it would be easier to isolate our issue and tweak it than bloat my simple script to allow multiple PIDs to be tracked and toggled...though the latter is certainly possible, and after I get my second OpenVPN server online (Audiogalaxy offline for better part of day yesterday, need to make myself independent of that), if the Java is too daunting I just may do so. So many tempting projects, so little time.
Simple VPN handler script to tide us over until 0.4.8 or more in OpenVPN-Settings
Ok, since you were so kind as to compile those extra modules for me, I figure the least I can do is give you something in return. Here's a simple VPN handler to manage multiple tunnels. Filenames for config files are entered relative to the CFGS folder, and module load/remove is manual rather than auto...and I put in connection sharing, as I'm using it this way...but it'll certainly let you use as many tunnels as the kernel will let you work with.
As always, the standard, 'you take your life into your own hands if you use this code, not responsible for problems up to and including user death' disclaimer applies. It seems to be working for me, though I'm only using 2 VPN's ATM.
Good luck! (Will still let you know if I make any progress in Java Dev)

Note: It'll throw out some screen errors if you don't have a zero length file in $CFGS/cfglist, but it'll let you add your first tunnel anyway. (Didn't bother to trap for that.)
Oh, and ScriptManager doesn't seem to like digging for scripts in /data/local/bin, but doesn't appear to have a problem executing things in /mnt/sdcard, even though I don't seem to be able to set the execute bit on any file in that fs. There's reference in Google of known glitch in some kernels that cause fs' mounted with the 'default_permissions,allow_other' flags to behave strangely. If they ever fix that, you may need to relocate, that's all.
Note also that the "ACT" column which denotes 'active' tunnels with an '*' only verifies that there is a process running with the designated label name. At this time, actual connectivity is left to you to determine.
it's very helpful, thanks very much!!
but could you compile nls_utf8.ko too? please
You should try and come up with a working recovery!

yes that is the md5 for the tun.ko .. in a rush i gave you the md5 for the zip of the tun.ko previously. are you sure you are running kernel 2.6.36.3+
it has to be exactly that kernel..with the '+' on the end
yes i am. or i was haha.. it was a friend's tablet. but it certainly had that kernel version. thanks for the help. if i get it again i may ask for help

Introduction
TurboBoost is a script package by me, Now due to the time i took in building a working ICS port for SGS2 with Cyanogen and TeamHacksung i got to study a lot about the ICS framework and working. Now what i did was to apply the same tweaks i found there on to a GB rom and vola TurboBoost was born!
Benefits
Better performance, better battery life through Linux kernel tweaks catered for Android OS and flash memory.
Better battery life and performance through usage of screenstate_scaling whereby it switches governors/thresholds/VM depending on your screen state.
Better network throughput from TCP tweaks and 3G tweaks
Less RAM usage through zipalign.
Faster database access through defragmentization of sqlite db files (a lot of apps use Database to store data like Swype dictionaries, Game saves etc)
Faster disk access through remount script (noatime, disable barrier etc)
Less lags through Quasi-charger, with multitasking
Requirements
Android Gingerbread 2.3.x
At least 2MB free on /system (Delete unused ringtones or useless apps like Aldiko/Allshare etc).
Root
Kernel that supports init.d
Ext4 lagfix if you want to use the remount script
Instructions
For the time being this is for developers and advanced users only,
SO I WONT BE PROVIDING ANY CWM PACKAGES if you dont know what to do with the package better not touch it let the developers do it for you
Personally's Developed
This will Zipallign every system .apk and framework @Boot!

echo 13060 > /sys/class/touch/switch/set_touchscreen;
echo 14005 > /sys/class/touch/switch/set_touchscreen;
In house ICS Developed Tweaks
Included libsqlite.so and libsqlite_ini.so from Android 4.0 (improves performance)
Included app_process and system_server from Android 4.0 (improves scrolling)
Included sqlite3 from Android 4.0
Included Vpn
Files In Package
Code:

Dont use a RAM script with this
Set the permissions to 777
Make sure if u use TB-V8 only use its content, and verify your personal tweaks dont tamper its functionality

Tried it and it works like a charm, about the benefits i can't tell at the moment, but i will as soon as i see any difference.
Oh and btw, pls also add the zip of the original thread here
First, let me apologize if solutions to this problem have already been posted on this forum and elsewhere. I developed this solution completely independently, and I am sharing it here in hopes that it may prove useful to someone else.
This pair of scripts will allow you to share your phone's Internet connection with a computer via a USB cable. It definitely works when the computer is running Linux (assuming you have RNDIS support in your kernel), and it should work as well when the computer is running Windows. However, it will not work with Mac, as OS X does not have an RNDIS driver.
First, upload these two scripts to your /sdcard:
/sdcard/usb_tether_start.sh:
Code:
#!/system/bin/sh
prevconfig=$(getprop sys.usb.config)
if [ "${prevconfig}" != "${prevconfig#rndis}" ] ; then
echo 'Is tethering already active?' >&2
exit 1
fi
echo "${prevconfig}" > /cache/usb_tether_prevconfig
setprop sys.usb.config 'rndis,adb'
until [ "$(getprop sys.usb.state)" = 'rndis,adb' ] ; do sleep 1 ; done
ip rule add from all lookup main
ip addr flush dev rndis0
ip addr add 192.168.2.1/24 dev rndis0
ip link set rndis0 up
iptables -t nat -I POSTROUTING 1 -o rmnet0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
dnsmasq --pid-file=/cache/usb_tether_dnsmasq.pid --interface=rndis0 --bind-interfaces --bogus-priv --filterwin2k --no-resolv --domain-needed --server=8.8.8.8 --server=8.8.4.4 --cache-size=1000 --dhcp-range=192.168.2.2,192.168.2.254,255.255.255.0,192.168.2.255 --dhcp-lease-max=253 --dhcp-authoritative --dhcp-leasefile=/cache/usb_tether_dnsmasq.leases < /dev/null
/sdcard/usb_tether_stop.sh:
Code:
#!/system/bin/sh
if [ ! -f /cache/usb_tether_prevconfig ] ; then
echo '/cache/usb_tether_prevconfig not found. Is tethering really active?' >&2
exit 1
fi
if [ -f /cache/usb_tether_dnsmasq.pid ] ; then
kill "$(cat /cache/usb_tether_dnsmasq.pid)"
rm /cache/usb_tether_dnsmasq.pid
fi
echo 0 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -D POSTROUTING 1
ip link set rndis0 down
ip addr flush dev rndis0
ip rule del from all lookup main
setprop sys.usb.config "$(cat /cache/usb_tether_prevconfig)"
rm /cache/usb_tether_prevconfig
while [ "$(getprop sys.usb.state)" = 'rndis,adb' ] ; do sleep 1 ; done
To start USB tethering:
Code:
adb shell "su -c 'sh /sdcard/usb_tether_start.sh'"
Grant the superuser request on the phone if one appears.
If you're on Linux, you'll see a new network interface appear (probably called "usb0"). Bring the link up on that interface (ip link set usb0 up), run a DHCP client, and you're all set!
If you're on Windows, it will probably Just Work™.
To stop USB tethering:

OMG !!!!
You rock ! This solution is the FIRST one which works on my international i9300 device (not a 'Sprint' version) with cm10.1.
I can't understand why ... but i'll keep your script on my ext SDCard.
I'll prupose this script to french cm10.1 users.
Thank you!

First, let me apologize if solutions to this problem have already been posted on this forum and elsewhere. I developed this solution completely independently, and I am sharing it here in hopes that it may prove useful to someone else.
This pair of scripts will allow you to share your phone's Internet connection with a computer via a USB cable. It definitely works when the computer is running Linux (assuming you have RNDIS support in your kernel), and it should work as well when the computer is running Windows. However, it will not work with Mac, as OS X does not have an RNDIS driver.
First, upload these two scripts to your /sdcard:
/sdcard/usb_tether_start.sh:
Code:
#!/system/bin/sh
prevconfig=$(getprop sys.usb.config)
if [ "${prevconfig}" != "${prevconfig#rndis}" ] ; then
echo 'Is tethering already active?' >&2
exit 1
fi
echo "${prevconfig}" > /cache/usb_tether_prevconfig
setprop sys.usb.config 'rndis,adb'
until [ "$(getprop sys.usb.state)" = 'rndis,adb' ] ; do sleep 1 ; done
ip rule add from all lookup main
ip addr flush dev rndis0
ip addr add 192.168.2.1/24 dev rndis0
ip link set rndis0 up
iptables -t nat -I POSTROUTING 1 -o rmnet0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
dnsmasq --pid-file=/cache/usb_tether_dnsmasq.pid --interface=rndis0 --bind-interfaces --bogus-priv --filterwin2k --no-resolv --domain-needed --server=8.8.8.8 --server=8.8.4.4 --cache-size=1000 --dhcp-range=192.168.2.2,192.168.2.254,255.255.255.0,192.168.2.255 --dhcp-lease-max=253 --dhcp-authoritative --dhcp-leasefile=/cache/usb_tether_dnsmasq.leases < /dev/null
/sdcard/usb_tether_stop.sh:
Code:
#!/system/bin/sh
if [ ! -f /cache/usb_tether_prevconfig ] ; then
echo '/cache/usb_tether_prevconfig not found. Is tethering really active?' >&2
exit 1
fi
if [ -f /cache/usb_tether_dnsmasq.pid ] ; then
kill "$(cat /cache/usb_tether_dnsmasq.pid)"
rm /cache/usb_tether_dnsmasq.pid
fi
echo 0 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -D POSTROUTING 1
ip link set rndis0 down
ip addr flush dev rndis0
ip rule del from all lookup main
setprop sys.usb.config "$(cat /cache/usb_tether_prevconfig)"
rm /cache/usb_tether_prevconfig
while [ "$(getprop sys.usb.state)" = 'rndis,adb' ] ; do sleep 1 ; done
To start USB tethering:
Code:
adb shell "su -c 'sh /sdcard/usb_tether_start.sh'"
Grant the superuser request on the phone if one appears.
If you're on Linux, you'll see a new network interface appear (probably called "usb0"). Bring the link up on that interface (ip link set usb0 up), run a DHCP client, and you're all set!
If you're on Windows, it will probably Just Work™.
To stop USB tethering:
Code:
adb shell "su -c 'sh /sdcard/usb_tether_stop.sh'"
Again, grant the superuser request on the phone if one appears.
That's it!

Change your DNS servers in Android.
You can change the same thing on your rooted Android Device.
[email protected]:/ # ndc resolver flushif -- flushes old DNS servers
[email protected]:/ # ndc resolver flushdefaultif -- flush resolver
[email protected]:/ # ndc resolver setifdns <iface> <domains> <dns1> <dns2> ... -- Add the new servers
[email protected]:/ # ndc resolver setdefaultif -- Set as the default device

With root privileges and a terminal app or (adb shell):
[email protected]:/ # ndc resolver flushif -- flushes old DNS servers
[email protected]:/ # ndc resolver flushdefaultif -- flush resolver
[email protected]:/ # ndc resolver setifdns <iface> <domains> <dns1> <dns2> ... -- Add the new servers

I've been struggling with this issue in these days.
As you said, something is significantly changed in Android 4.3+
None of programs I tried so far worked.
This is my solution, not noob friendly!
adb shell
su
mount -o remount,rw /system
vi /etc/dhcpcd/dhcpcd-hooks/20-dns.conf
in vi editor you'll see set_dns_props() funtion which sets up dns servers when a wifi connection is established.
Code:
set_dns_props()
{
case "${new_domain_name_servers}" in
"") return 0;;
esac
count=1
for i in 1 2 3 4; do
setprop dhcp.${intf}.dns${i} ""
done
count=1
for dnsaddr in ${new_domain_name_servers}; do
setprop dhcp.${intf}.dns${count} ${dnsaddr}
count=$(($count + 1))
done
separator=" "
if [ -z "$new_domain_name" ]; then
separator=""
else
if [ -z "$new_domain_search" ]; then
separator=""
fi
fi
setprop dhcp.${interface}.domain "${new_domain_name}$separator${new_domain_search}"
}
as you see new_domain_name_servers contains dns servers array
add this line
Code:
new_domain_name_servers="8.8.4.4 8.8.8.8 $new_domain_name_servers"
function will be like below
Code:
set_dns_props()
{
new_domain_name_servers="8.8.4.4 8.8.8.8 $new_domain_name_servers"
case "${new_domain_name_servers}" in
"") return 0;;
esac
count=1
for i in 1 2 3 4; do
setprop dhcp.${intf}.dns${i} ""
done
count=1
for dnsaddr in ${new_domain_name_servers}; do
setprop dhcp.${intf}.dns${count} ${dnsaddr}
count=$(($count + 1))
done
separator=" "
if [ -z "$new_domain_name" ]; then
separator=""
else
if [ -z "$new_domain_search" ]; then
separator=""
fi
fi
setprop dhcp.${interface}.domain "${new_domain_name}$separator${new_domain_search}"
}
Edit: in vi editor
press i to edit mode. Make your changes then press esc. type :wq to write/exit

Thank you very much, works in 4.4.2 on a LG G2, too.
(And if you use Root-Explorer, you don't need adb and vi, the File-Editor of Root-Explorer is easier IMHO.)
Needed that to use a home dnsmasq Server to access an internal owncloud Server with a router without NAT-Loopback.
PS:
A reboot is needed to make that work.

Does it reliably work on 4.4.2? I'm surprised because I wrote an application which use the "ndc" command to override the DNS values.
I thought it was the only way...
P.S. My application is called "Override DNS for KitKat" and it's on the Play Store.

Reboot is not required, just restart your wifi.

Yes it does work on 4.4.2
Two additions:
1. IMPORTANT!
If you - as I proposed before - use Root Explorer to edit the 20-dns.conf file, Root Explorer will create a backup file called 20-dns.conf-bak. This file is parsed as well! So you have to delete that backup file if you don't want to have double definitions..
(I notices this, as my own DNSMASQ Server 192.168.2.222 was dns1 and dns2 as well...)
2. In order to avoid waiting for a timeout in another WLAN than my home WLAN, I wanted this custom DNS settings only to be applied in my own WLAN. So I wanted to include an if-condition that is only applied in my home-WLAN. As 20-dns.conf is some sort of bash file, I used the getprop function to find out how I could identify my own network. Unfortunately, there is no way to get the SSID, but something nearly as good: the Domain!
Type in a terminal on your android device:
Code:
$ getprop | grep domain
[dhcp.wlan0.domain]: [Speedport_W_921V_1_35_000]
(in my case.)
So I changed my /etc/dhcpcd/dhcpcd-hooks/20-dns.conf to only apply a custom DNS for that domain:
Code:
# Set net.<iface>.dnsN properties that contain the
# DNS server addresses given by the DHCP server.
if [[ $interface == p2p* ]]
then
intf=p2p
else
intf=$interface
fi
set_dns_props()
{
if [ "$new_domain_name" == "Speedport_W_921V_1_35_000" ]
then new_domain_name_servers="192.168.2.222 ${new_domain_name_servers}"
fi
case "${new_domain_name_servers}" in
"") return 0;;
esac
count=1
for i in 1 2 3 4; do
setprop dhcp.${intf}.dns${i} ""
done
count=1
for dnsaddr in ${new_domain_name_servers}; do
setprop dhcp.${intf}.dns${count} ${dnsaddr}
count=$(($count + 1))
done
separator=" "
if [ -z "$new_domain_name" ]; then
separator=""
else
if [ -z "$new_domain_search" ]; then
separator=""
fi
fi
setprop dhcp.${interface}.domain "${new_domain_name}$separator${new_domain_search}"
}
unset_dns_props()
{
for i in 1 2 3 4; do
setprop dhcp.${intf}.dns${i} ""
done
setprop dhcp.${interface}.domain ""
}
case "${reason}" in
BOUND|INFORM|REBIND|REBOOT|RENEW|TIMEOUT) set_dns_props;;
EXPIRE|FAIL|IPV4LL|RELEASE|STOP) unset_dns_props;;
esac
(you see the if-condition with the domain added...)
You can watch the settings with
Code:
$ getprop | grep dns
The settings are applied after a connection change, as [email protected] stated right.
PS: I don't use a Galaxy Note, but a LG G2, and not Android 4.3, but 4.4.
This seems to work in general, maybe the thread is better located in a general section than in a device-specific section?
Change DNS on kk 4.4.2 on 3G or 4G
Hello guys
i have been searching for a way to change my dns on kk 4.4.2 while on mobile date network but no luck is that anyone can help me to do that plz.
Thanks
Any methods that work for lollipop?
The script worked for my Samsung GS2 but my Moto XT1644 doesn't have a system/etc/dhcpcd directory. Is it OK to create the directory tree and copy a downloaded 20-dns.conf script into it? If so, would I need to set permissions for the modified script?
If your like me, you use the Netflix profiles and you don't want to use and old version. Nor do you want to disable auto app updates.
I call this a workaround because you have to do it before you run Netflix... Every time. But maybe someone with more experience can make it permanent. Also I think it disables HD Video in Netflix.
Simply open /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml as a text document and place "nflx_player_type" value="8" on the next line under <map>
If you want, you can place the following in a *.sh file and run it with script manager with super user selected.
if [ -f /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml ]; then
grep -q nflx_player_type /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml && exit 0
cp /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml.orig && sed -e 's|</map>|<int name="nflx_player_type" value="8" />\n</map>|g' /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml.orig > /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml && rm /data/data/com.netflix.mediaclient/shared_prefs/nfxpref.xml.orig

I have an issue of a gray screen but audio on the netflix app using CM 11.
The above seems to be too much work. I found Netflix Black instead which works fine, but no chromecast support.

I can confirm that Netflix Black does work fine with CM11.
