EDITED 30/8/2011
Did a lil research and found d solution..
U need to have Terminal Emulator installed first(needs root)
den type d follwing in terminal emulator:
$ su
Allow super user permission
$ getprop
$ setprop net.pdp0.dns1 value1
$ setprop net.pdp0.dns2 value2
$ setprop net.dns1 value1
$ setprop net.dns2 value2
where value1 is d first dns address eg. 202.255.255.255
value2 is the second dns address(if there is a second dat is)
using the setprop u can change certain properties that u can see from the getprop output(still do this at ur own risk)
Also note the dns is changed only for one session..
u have to repeat the above steps for every session..
if u find a beter way please post it..
It is not working on this phone so why bother?
The Tether app is opening and running, you can connect to the apn but you wont get internet.
I don't have a solution for this but may I remind you this is development section.
How to Setup DNS for APN in Internet Setting
Please ask if u didnt understand d above method .. i'll try my best to clear it out
Domain Name System / Server is the one which takes care of translating the human readable domain names into machine understandable IP addresses. If you are not able to access a particular set of websites either from your laptop /phone, DNS server could be a reason for it. To fix the problem, one has to change the network configurations to use some of the popular DNS servers like Open DNS or Google’s public DNS. On Android phones, changing the DNS server is easy if you are using the static IP. You can do it from Settings > Wireless & network settings > Wi-Fi settings > Advanced (from menu) > check the ‘Use static IP’ option. After that, you will be able to change the DNS servers. However, when you are using dynamic IP (which will be the case most likely), the process is not straight forward. DNS server details will be taken from the DHCP server which assigns the IP.
Here are the steps to be followed to change the (WIFI Connection) DNS servers:
- Android system chooses the DNS servers using the script located at “/system/etc/dhcpcd/dhcpcd-hooks/20-dns.conf”
- By default, /system partition is mounted as read-only. Need to re-mount the same in re-write mode.
- Take a backup of the script. Download the modified version of the script from here (http://varun-scratchpad.googlecode.com/svn/trunk/static/20-dns.conf). The modified script has two additional lines which will override the DNS server changes. The modified script uses the Google’s public DNS.
- Changes will be applied after restarting the connection /device.
3G Connection:
- Download the wrapper script from here (http://varun-scratchpad.googlecode.com/svn/trunk/static/change-dns.sh) This wraps all the commands needed for changing the DNS server in a shell script.
- Download and install an interpreter for executing your shell script from your phone (e.s. scripter from Rom Toolbox)
- Launch the script. Grant the Super permission when asked.
- You just have to run this script whenever you are connecting to your mobile network.
Done. You settings are proper by visiting http://welcome.opendns.com. Remember, the settings will be applicable only for the current session.

Thank you for sharing, but I have to say that the "setprop" method does not work on KitKat (I'm talking about mobile connections).
I wrote an app called "Override DNS for KitKat" to solve this issue. It's on the Play Store.
There's a much more reliable and easier method. Just use this as AFWall custom script or use manually in init.d (replace '$IPTABLES' with 'iptables' and just use the last 2 lines).
Code:
$IPTABLES -t nat -D OUTPUT -p tcp --dport 53 -j DNAT --to-destination 208.67.222.222:53 || true
$IPTABLES -t nat -D OUTPUT -p udp --dport 53 -j DNAT --to-destination 208.67.222.222:53 || true
$IPTABLES -t nat -I OUTPUT -p tcp --dport 53 -j DNAT --to-destination 208.67.222.222:53
$IPTABLES -t nat -I OUTPUT -p udp --dport 53 -j DNAT --to-destination 208.67.222.222:53

Hey, wondering if it would be possible to share the internet connection via wifi from reverse tether?
PC > Android > Wifi Hotspot > Other Device
Basically my 3G internet plan doesn't include tethering so I'm looking for a way to get internet on other devices in the room via wifi...
Though the computer does not have a wifi card so wondering if it would be possible to use the android device as a wifi switch?
I can connect my device to the internet through the PC connection via ADB Reverse USB Tunnel.. But then can I then enable wifi tethering to use that connection to share across the wifi for other devices to connect to and then share the same PC connection?
If its not possible I'm sure I'd be able to install drivers for one of my USB wifi cards, not ideal but if its the only way then I guess I'd have to.
Cheers, Dave
I also scoured everywhere and only thing i found was an app that allowed phone to use computer internet but don't think it broadcasted like Wi-Fi to other devices. I'll look in my Google play and try to locate it.
*Shaolin Shadowboxing*
I have my phone using the PC connection okay, but was looking to then share that through the phone wifi.. but I guess that wouldn't work.
I have a USB wifi adapter that I can setup to share the connection.

Yes. Search reverse tether in play store.

Connected via cable, there's no other connections available hence I was using USB Tethering on my Android phone..
Since there's no wifi available I'm just looking for a way to share it to others and my iPod etc..

I have been looking for something like for .. forever, I am truely amazed to have finally find something that hints that it was done
did you really get it to work properly?
I have rooted 2.3 and xp,
if I have busy box installed and I run these via ssh server on my droid, should it work for my setup as well with no changes?
I am really surprised nobody ever made an app that does that automatically, this stuff is so basic and actually super useful and needed!
A random question but have you tried the "Fox-fi" app? i haven't tried to do this myself, but it's a little more flexible than the build in options, it may give you what you are looking for. I've used fox-fi in the past for abnormal tethering, short of going out and buying a cheap USB WiFi adapter of course..

in case you asked that me,
my rom has a built in hotspot feature, so I don't need an app for that
I am AMAZED that there are countries in which you are charged extra if you waste your already-paid 3g traffic via another medium that is not particularly your android.
really, next thing you you, you will be charged for having a private phonebook that helps you remember numbers instead of clicking on digits every time you want to call someone, because the cell-supplier wants you to pay extra to use it's phonebook app...
as far as I know from testing FoxFi, its not capable of turning the android into a router, thus bridging the two networks together
and by two networks, I mean the network created by connecting the android via usb to the pc,
and connecting the android via hotspot wifi to another pc/laptop/w'e

Which device was it?
Didn't get it working here on cyanogemod 11 anyway, got reverse tethering as much. The op doesn't explain which commands are for the linux and which ones for the phone, and he's the only one that claims it works. A further explanation is necessary. Attachment is for clarification.
The ppp adapter in my case was rmnet0.
So, I modified it as:
## Disable mobile-data.
#
busybox ifconfig rmnet0 0.0.0.0
After following all the steps, I get internet connection on mozilla firefox on Android for a few seconds but then immediately firefox goes to offline mode. I am able to ping servers like facebook from terminal emulator and I am even able to get internet on default browser.
But I can neither get internet on Google Play apps nor get internet on my laptop to which I tethered my Android device using portable wifi hotspot.
What could be the possible issue here ?
---------- Post added at 06:14 PM ---------- Previous post was at 05:32 PM ----------
can you please explain the purpose of using -o flag in setting the NAT rule for masquerade ?
iptables -t nat -A POSTROUTING -o usb0 -j MASQUERADE
I am assuming that usb0 here is the adapter through which the Android device recieves data from the system (Ubuntu Desktop in my case).
So how does usb0 become the output interface ?
Our intention is to share the reverse tethered network via portable wifi hotspot. So we need to masquerade all traffic recieved by the device to the wifi adapter say wlan0.
So shouldn't it be :
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
Or is there any need to specify an output adapter, because
Initially we did set up reverse tethering from the Linux Desktop (the Linux Desktop without GUI case) and there,
we masqueraded packets recieved from ethernet adapter (ethernet connection from wired router) to the usb adapter (usb used for reverse tethering).
For that we did not specify any output adapter anywhere.
So would this be fine :
iptables -t nat -A POSTROUTING -j MASQUERADE
Having said these, I was not able to successfully reverse tether as I was getting reverse tethered data only on terminal emulator and default browser and not on Google Play apps. I have added details in another comment for that.
got it working for me!
reversed tethering worked for me by following the instructions and calling "netcfg usb0 dhcp".
However the WiFi tethering didnt work at first: Other Devices could connect to my phone but no data was forwarded...
The problem was that iptables was not setup properly...
Now I just connect my phone to the pc, enable usb tethering and wifi tethering and run the following:
Code:
adb devices
pause
adb shell netcfg usb0 dhcp
adb shell busybox ifconfig rmnet0 0.0.0.0
adb shell echo 1 > /proc/sys/net/ipv4/ip_forward
adb shell iptables --flush
adb shell iptables --delete-chain
adb shell iptables --table nat --delete-chain
adb shell iptables --table nat -F
adb shell iptables --table nat -X
adb shell iptables -t nat -A POSTROUTING -o usb0 -j MASQUERADE
adb shell iptables -P FORWARD ACCEPT
adb shell iptables -A FORWARD -i usb0 -o wlan0 -j ACCEPT -m state --state RELATED,ESTABLISHED
adb shell setprop net.dns1 8.8.8.8
Hope this helps

After reading several posts on mac spoofing and having failed to find a working thread.I decided to fill in the gaps with my linux knowledge (however little of that I may have).
So this method seems to solve some issues I've seen (MAC not changing because device wasn't downed) in these threads:
http://forum.xda-developers.com/showthread.php?t=1385577
http://forum.xda-developers.com/showthread.php?t=902354
without editing the nvram.txt
I've tested the ip link method on my recently rooted Samsung Tab 2 7.0"
Changing your mac address:
Prerequisites:
*A rooted device
*Busybox
*Terminal emulator
*Turn wifi on from your device's menu, do not connect to any network.
*Open your terminal emulator, now type:
$su
#ip link
*This should list all networking interfaces, identify your wifi device, take note of the name. now:
#ip link set NAME down
#ip link set NAME address 00:11:22:33:44:55
#ip link set NAME up
I believe that when using ifconfig the procedure is as follows:
$su
#ifconfig
*Take note of the device name
#ifconfig NAME down
#ifconfig NAME hw ether 00:11:22:33:44:55
#ifconfig NAME up
After doing the above you can connect to the desired network normally, using the default / other user interfaces.
NOTE: The mac address will be reset when WIFI is switched off.
I have confirmed the ip link method to be working. i.e. transmitted mac address is the new / changed one!
Actually in my case (SGS) i had to restart wifi first and then (while it's starting) quickly change the MAC using:
Code:
busybox ifconfig wlan0 hw ether 00:11:22:33:44:55
Important: It must be done about 500ms after enabling wifi, otherwise it won't work.
If I change MAC when wifi is off it simply returns to the original during next start.
Worked on i9000 with CM9 / 10

# ip link set tiwlan0 address 00:11:22:33:44:55
ip: SIOCSIFHWADDR: Operation not supported on transport endpoint
# ifconfig tiwlan0 hw ether 00:11:22:33:44:55
error: SIOCSIFADDR (Invalid argument)
I guess its a kernel/driver problem... at least I know it works on normal Linux systems.

Funny that only some manufacturers disable such features. You could always try editing the nvram file? I haven't tried it though.
Isnt it dangerous ?
Script to apply random mac
I've made a script to create a random ghost mac every time I run it on the terminal emulator with su.
Code:
macaddr="52:54:$(dd if=/dev/urandom count=1 2>/dev/null | md5sum | sed 's/^\(..\)\(..\)\(..\)\(..\).*$/\1:\2:\3:\4/')"
ip link set wlan0 down
ip link set wlan0 address $macaddr
ip link set wlan0 up
I've named it as gmac.sh and saved it on /sdcard/, thus by running:
Code:
$ su
# sh /sdcard/gmac.sh
the mac is changed.

Works differently on HTC Desire
Hello,
This is just to "set in stone" somewhere in the Internet that on some devices, you need *not* to down and up the network interface. Otherwise, the network driver will restore its MAC address from hardware/driver settings.
On a HTC Desire, MAC spoofing works this way:
* turn on the wifi interface using the standard Android interface
* run this script :
Code:
macaddr="52:54:$(dd if=/dev/urandom count=1 2>/dev/null | md5sum | sed 's/^\(..\)\(..\)\(..\)\(..\).*$/\1:\2:\3:\4/')"
ip link set wlan0 address $macaddr
Best regards,
On some devices (e.g. HTC Desire among others), the wifi GUI still resets the mac address even with the method described in this thread.
worstenbrood has modified the wifi driver so that the mac address can be configured from a text file. It is described here:
http://forum.xda-developers.com/showthread.php?t=1525230
This is compatible with the wifi GUI and solves the problem of the wifi interface reloading its original mac address.
Anyone interested, I have backported his modifications to the latest state of the kernel developement in CM7.
thanks!
I get a 'operation not supported on transport endpoint' error when running the 'ip link set wlan0 address 00:11:22:33:44:55' and a about the same error with busy box.
Thanks for this! Gonna try this later.

Change your DNS servers in Android.
You can change the same thing on your rooted Android 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
[email protected]:/ # ndc resolver setdefaultif -- Set as the default device
