Before i start i want to let people know YES I DO HAVE A WIRELESS ROUTER!! So please do not respond telling me to just go buy a router.
REQUEST - Reverse wired tethering. I.E. Sharing PC's iNet connection with your phone via USB.
REASON - My university's wireless is locked down and does not allow mobile phones, pda's to connect up to our wireless without submitting MAC for approval. Looking to sync certain apps without using my data connection.
I dont know if anyone has played around with trying to get this working or not. I know its a small market of people who may be interested in this, but for certain places (CANADA) where data charges are WAY to expensive this could be handy for students at UNI where wireless is not an option.
get a second wifi adapter on your laptop, and share your uni wireless network connection with the second wifi adapter. Use a hidden SSID, then no one will know what is going on
This was asked a couple of times before here and I remember people saying you couldn't reverse the tethering.You could try though.

Thats a good idea xD
Hey guys,
I have been trying to find a way to do this for a long time.
The best solution i have found (actually the only solution) is Connectify. The only downside is you must have Win7.
What it does is turns your wifi adapter into a HotSpot, even if you are using wifi to get the net in the first place. Its a great tool and should be what your after.

thank you so much for this
Your best solution is the WiFi adapter. You could most likely get away with a SOCKS proxy over USB, possibly using adb, but it would be complicated, unstable, and messy.
I still don't know you just don't use your wireless router. I assume they have wired. Clone your PC's mac address and hook it up. Universities are retarded with that crap. They have the worst networks and security.
If no wired, then what podunk place is it? haha
Even if they had only wireless , you could set up a wlan client and repeat it. DDWRT, etc, ftw.
Just get backtrack for your laptop and spoof your mac to all 0 then grab connect to the network at your school the spoofed mac will allow you to browse so long as no other encyption is on the network such as WEP or WPA.
then you can try to flood all the ports on the network so no one else can connect then spoof your phones mac by conneecting to your laptop through wireless as an adhoc connection and while staying connected through adhoc load a second server through the same wireless network card and you can connect to the achools network again. and walla...

so simple, i dunno why i didnt think of that. thanks! lol
Well its quit simple once you learn your way around linux...
If you have any experience with *nix, you may want to look at Cyanogen's original usb tether shell script:
http://github.com/cyanogen/android_vendor_cyanogen/blob/master/bin/usb-tether
Basically you could use the internet connection sharing function that comes with all popular OSes and access your uni's network on your phone. You must have Cyanogen mod or another mod using his kernel. Not yet working on OSX for some reason. Tested under Windows 7.
First you'll need to figure out what IP address range your computer's DHCP server is using. This is normally fixed for each OS. For Windows 7, it's always 192.168.137.0/24.
For OSX or Linux, you can setup connection sharing (for some other connection because we don't have the USB interface yet) and ifconfig.
Second is to enable the USB connection on the phone's side. Type the following command in any console program, like Connectbot. (You must use a console program as opposed to adb because you will lose USB debugging once the USB network interface is enabled.)
Code:
su
cd /sys/devices/virtual/net/usb0
ifconfig usb0 192.168.137.200 mask 255.255.255.0
echo 1 > enable
The first line makes you the superuser. (Skip if the command prompt is #)
The second line land you in usb0's directory under sys. We'll need to type the disable command later, so it's easier if we're here.
The third line brings up the virtual usb network interface and sets its IP address.
The IP address should be in the same network (i.e. IP address range) you obtained in step 1. Say if the original is 192.168.137.1 in a /24, you can use 192.168.137.2 through 192.168.137.254
This actually enables the usb interface.
You will now see a new network adapter is recognized by your computer. Set up connection sharing to share your internet TO that adapter.
Make sure you have connection by pinging your computer from your phone.
For example:
ping 192.168.137.1
Now you'll have to change the routes so traffic go through the USB cable instead of the mobile network.(# is the command prompt, do not enter)
# busybox route
check the line starting with "default". Write down the ip address after it; call it IP1.
# getprop net.dns1
Call the IP returned IP2.
Code:
busybox route del default gw IP1
busybox route add -host IP2 rmnet0
busybox route add default gw 192.168.137.1
The first line deletes the old default route via the mobile network.
The second line adds an "exception" for your carrier's DNS server.
The third line adds the new route via USB. You should replace the address at the end with the IP address from the first step.
Your network should be working now. Test by visiting some website that is only available on campus or by traceroute.
You must make sure the mobile network is always connected though. This is because domain names are still resolved by your mobile carrier. If you ever lose your mobile connection, the routing table will be changed as well.
To disconnect:
Make sure you're still in /sys/devices/virtual/net/usb0.(Use pwd if unsure.)
Code:
netcfg usb0 down
echo 0 > enable
The usb interface will disappear on your computer.
Now switch the phone to airplane mode and back to re-enable mobile network.
The disconnect step should always restore your phone's state.

It's really sad that Android can't reverse tether. If you want to use your laptop's AdHoc connection you have to do serious hacking to the tiwlan.ini and the wpa_supplicant.conf. There is no way to connect via bluetooth ar USB.
I'm seriously considering WP7 now for my next OS of choice... A nd for everyone saying "go buy a router" - go buy a router and stick it up your .... nose.
Hi,
I have the same problem. No WiFi in my work and no WiFi in my current home (a Resident Hall). There's no possibility to buy a WiFi router, of course. I tried to hack the system to connect ad-hoc networks but it didn't work.
I have found some interesting resources:

I have a HTC Magic with the ADP-DRC83 hacked ROM with Usb tethering integrated. But usb0 interface in the mobile is configured to provide Internet connection (as gateway) to the PC, not the reverse functionality: connecting the mobile to Internet through the PC. So, all I need is to change the gateway in Android and then configure a NAT-DNS in my linux PC (easy with iptables and dnsmasq). But, I don't know how automatize the process exactly.

Wind will be launching in vancouver soon.

Silly ragin' cajun.
Ok, now it works. Here it's my procedure for a HTC Magic (Sapphire) without any APN previously configured from Telecom provider and ROM CSDIv4.
In the mobile by using Better Terminal:
Code:
su
cd /sys/devices/virtual/net/usb0
echo 1 > enable
ifconfig usb0 192.168.2.2 mask 255.255.255.0
busybox route add default gw 192.168.2.1
setprop net.dns1 8.8.8.8
In the linux computer:
Code:
sudo sysctl -w net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i usb0 -j ACCEPT
sudo ifconfig usb0 192.168.2.1 netmask 255.255.255.0
Android Market downloads and location service don't work but I think is possible if you switch on the WiFi.
Update: Syncronization, Android Market downloads and location service don't work even the WiFi antenna is switched on. I have added the iptables commands also.
Well gosh, reverse wireless tethering is so much simpler
There are another similar thread: http://forum.xda-developers.com/showthread.php?t=522498
How can I join an Android device to a Bluetooth PAN (Personal Area Network) as a client? In some areas, the only internet connection available would be to tether it through another cell phone via bluetooth PAN (other phone has no wifi).
Solutions that require rooting or config file editing are OK.
I've searched alot, but all results are about going the other way - tethering other devices through the Android.

It's Linux, man, all you need is setting network config I was using reverse tethering for some time, this is my script (run on PC):
Code:
sudo pand --listen --role NAP
adb shell pand --connect XX:XX:XX:XX:XX:XX
sudo ifconfig bnep0 192.168.101.1
adb shell ifconfig bnep0 down 192.168.101.2 up
adb shell route add default gw 192.168.101.1 dev bnep0
adb shell setprop net.dns1 192.168.101.1
Of course you should omit 1st and 3rd lines.
Are you sure second phone supports PAN connections, not DUN? PAN is quite complicated for phone, because it requires full NAT.
And you will have problems with Android Market and some other apps. Internet is configured at linux level, Android OS don't know about it, so if application asks: "Do we have internet connection?", Android replies: "No". Android Market will wait for connection even if there is one.

But most of the apps don't check internet status and just use it - they will work. AFAIR I couldn't use Market, GTalk and syncing feature, but Browser, Gmail and many, many more was working.
If you have any WiFi device then you could connect Android to it. Even if it doesn't share internet connection, Android OS will think, that it does (but will use BT connection configured at linux level ) - then any app should work.
At work I got a laptop with windows XP, There's a wireless network but it's EAP secured and I can't connect to it with the phone (Motorola Milestone - Android 2.1).
Did you manage to make internet work through Bluetooth PAN? I just need to use the borwser, so It's not important if market or other apps don't work.
I have android sdk with adb on my laptop and terminal emulator with busybox on my phone. I'm kind of a newbie in this so some hints would be nice. I think many people like me would be gratefull

And my first post was about what, you think? I don't use it now, but I was reverse-tethering through BT for several months, until I bought some data plan.
Above commands should work for you, but... they will let you connect your phone to PC, but I don't know, how to share internet connection on Windows XP. AFAIR I tried to do it, but failed.
There's a bluetooth network icon. I know it's possible to share the internet connection from my ethernet to the other network cards. So this should work also with the bluetooth network.
I will try the commands and see how it goes.

Unfortunately not ;-) It is a cost of easy-clicking-configuration that Windows has - it's very limited, don't work for BT connections. I guess there is some professional software for internet sharing on Windows, but I don't know one.

I did this with my symbian phone. I managed to share internet to the bluetooth network, but the phone had a bluetooth PAN profile that connected to my laptop.
No! Already I have a bluetooth network set up on my Ubuntu Laptop - pand is running and there is a dhcp server monitoring the interface. What I need is not the below advice, which are commands to run on the PC, but an application / utility / instructions for enabling BLUETOOTH PAN CLIENT on Android. That is what the original question was too! Anybody?

4 of 6 lines of my instructions were for setting Android client: connecting, setting IP, routing and DNS. And yes, they are run on Android, not on PC - I thought you will notice "adb shell" prefixes... You can also use dhcpcd instead of last 3 lines, but if you don't understand, what are you doing, you will have problems anyway.
Maybe anyone with Froyo can confirm that there's still no official option for joining a Bluetooth PAN from Android there?
@Brut.all So I guess there's currently no way to kind of telling Android there's a configured connection on Linux level?
By the way, every Mac allows the creation of a Bluetooth PAN with one click so this would be my usage scenario ;-)
This seems like it should work, and indeed I can use a similar technique from an ubuntu laptop to connect to another device, but my HTC Hero doesn't seem to have hcitool or pand installed on it. I downloaded some prebuilt binaries for them but they don't seem to be able to access the bluetooth device:
# /data/tmp/pand --role PANU --connect 00:17:83:0F:0F:C7 -n
pand[5083]: Bluetooth PAN daemon version 3.36
pand[5083]: Connecting to 00:17:83:0F:0F:C7
pand[5083]: Connect to 00:17:83:0F:0F:C7 failed. No route to host(113)
Do all versions of Android come with pand and hcitool? I'm on 1.5 although I'll be reflashing to 2.1 soon.
"find / -name pand" yields no results

No, it was added by rom cookers and I don't know how they did this. I think there are missing some kernel modules or something like that.

Thanks, I've got the FroydVillain ROM installed now and can confirm that it comes with pand and hcitool compiled and working.
Reverse tether does seem to work, the method that's worked for me has been to use:
Code:
pand --connect <remote BT device hex address>
ifconfig bnep0 down
dhcpcd bnep0
setprop net.dns1 8.8.8.8
This allows the device to access the internet, and you can ping www . google . com and get a response etc.
However, a lot of android apps (including the built-in google apps for gmail etc) use the ConnectivityService (see source code here) to access the net, and since this method of reverse tethering doesn't change the connectivity state within this service, those apps still believe that there is no internet connection on the device.
I can't see an easy way of "tricking" the ConnectivityService as it appears to have been hard coded to only cater for WIFI and 3G connectivity. So perhaps the only way is to rewrite it.
I've found a few cases of others going through the same issues online, although I think the getMobileDataEnabled return value is a red herring:
(I'm not allowed to post links, so you will need to add http : // www to these
superuser.com/questions/188636/close-connect-android-to-internet-using-usb-tether-through-laptops-newtwork
forceclose.com/questions/2669/connect-android-to-internet-using-usb-tether-through-laptops-newtwork
Looking at the code in ConnectivityService.java it seems that apps must subscribe to this service via getInstance() and then wait for a sendConnectedBroadcast() to occur, triggering them into action (e.g. the gmail app will attempt to sync to the gmail server etc).
Anyone got any ideas for an easier route than rewriting ConnectivityService.java to add an additional connectivity type?
Edit to add:
Found another related discussion at the following site. Seems to suggest modifying the ConnectivityService is the way to go:

Based on the posts I've seen in this thread, I'm guessing I can't use BlueTooth PAN tethering from my rooted Dinc to provide internet access to a Samsung Galaxy Tab???
So has anyone tried to Bluetooth tether a Galaxy tab with a phone?
Thanks for this thread! I just successfully Tethered both internet+gps over bluetooth from my G1 to my AdventVega tablet.
For now I am using GScript lite with the following script commands:
Code:
pand --connect {my phones BT hex address}
ifconfig bnep0 down
dhcpcd bnep0
setprop net.dns1 8.8.8.8
dhcpcd bnep0
(for some reason the first dhcpcd command always says permission denied, but the last one always works)
So...
1) Get in to car with Android phone and Vega Tablet.
2) On phone: Enable GPS/Bluetooth, click GPS2Bluetooth widget button, click WiFi Tether (configure for BT), press to start tethering.
3) On tablet: Enable Bluetooth, click Bluetooth GPS Provider, click Start, click Back or Home, click GScript Lite, click "Connect to BT-PAN" (above script)
4) Run GoogleMaps/Navigation on tablet and enjoy using your tablet as the ultimate GPS navigation system (while streaming Pandora in the background)!
I am very happy. I just wish I could make step 2 & 3 be a single click instead of so many.
NOTE: Must have "Allow mock locations" enabled in Settings->Applications->Development
NOTE2: You must pair your phone and tablet in BT settings (it will never say "connected" though, which is fine)
I tried this, but still no connection between my android phone and the other phone. Is there some other method?
As the subject states, non of the current roms/kernels appear to have the TUN/TAP driver to run openvpn.
Side note.. ATT pissed me off today (okay so I had it coming for tethering but still..) So, new solution is to run openvpn and force all the traffic through my openvpn gateway, this will keep ATT from spying, and also prevent them from using TTL (still speculation, but one of the methods to detect tethering)
Just out of curiosity, how did you confirm that the TUN/TAP driver was non-existant or not operating properly on the skyrocket?
I'm in the midst of doing the same ... installing openvpn. I have the server set up on my home PC and verified through another laptop off-network. But I have problems when trying to run openvpn settings. Here is what I did:
1) Copied .ovpn file, ca.crt, client1.crt, client1.key, ta.key FROM server TO /sdcard/openvpn directory on skyrocket
2) Installed busybox
3) Installed openvpn installer
4) Installed openvpn using #3
5) Installed and opened openvpn settings
6) Under "OpenVPN Settings" I checked the box saying "OpenVPN"
7) Under "OpenVPN Configurations", I selected my .ovpn file's checkbox
8) The .ovpn checkbox immediately disables and I have no openvpn
Was your approach similar?
I just checked via lsmod. I did not bother going through the process of moving my config files from my captivate to the skyrocket.
Samsung does not include the tun/tap driver in the stock kernel, so it will require a custom kernel, or at least someone to create the module with the same libraries as the stock kernel and just the tun.ko module file to copy across to our current phones.
Actually TUN/TAP is compiled directly into the stock kernel and not compiled as a module so you won't find it with lsmod. You also don't need to do an insmod to use it. I'm running openvpn just fine in tap mode.
There IS a bug in the OpenVPN Installer though that requires you to have ifconfig and route in /system/xbin/bb. It won't work if you select anything else during the openvpn install.
Here's what I did...
Install busybox to /system/xbin
Install openvpn to /system/xbin and select /system/xbin/bb as the location of ifconfig/route
adb shell or use a terminal on the device and do a su.
mount -o rw,remount /dev/block/mmcblk0p24 /system
mkdir /system/xbin/bb
cd /system/xbin/bb
ln -s ../busybox ifconfig
ln -s ../busybox route
mount -o ro,remount /dev/block/mmcblk0p24 /system
Configure and start openvpn.
Good to know.
Will try it in abit, I tried to run openvpn, but it failed on the tun driver, which is why I stopped, but I did not link bb, will give that a try when I get a chance... stupid ATT busted me for unauthorized tethering again.. so cannot get my existing openvpn config from my server yet...

I tried the directions you provided but with using tun and no luck. I'll try and reconfigure my openvpn server to run tap and will try agian.

Can you try running openvpn from a command line and see what errors it spits out?

Also can you check if /dev/tun exists?

I had no problems getting it to work, I borrowed my co workers usb modem to pull down my configs from my old Captivate (I use ssl-admin and store the configs with the certificates in zip format).
The problem I am having at the moment is getting tethering to work while openvpn is running.
Laptop can talk to the phone (using wifi tethering, usb tethering kills the adb session, but I suspect it would work just fine), and phone can talk to the world, but laptop will not connect to the world.
The routes are in place, I checked the sysctl options, and ip forwarding is enabled. Just no traffic will pass... it is driving me nuts... heh.
Success for me too! Not sure what was wrong. The server was always working no problem and was always able to connect directly over home wifi from laptop. But I wasn't able to connect on the Skyrocket.
But I used gtj0's config file, changed the remote ip address/port, and worked perfectly. Thanks!
jvanbrecht: I haven't tried it with tethering yet and probably won't get to until at least a few days. Hope to be able to help by trying on my phone sometime soon.
Everyone: Any idea if it is better to run tun or tap for mobile phone openvpn? Regarding tethering, do both tap and tun hide detectable elements like TTL at the IP layer?
EDIT: VPN Not Porting Properly?
Hmm. It seems I am able to connect no problem and openvpn on the phone says it's connected. But when I go to www.whatismyip.com from my phone, it still says an AT&T address. I expected with openvpn running that it should show my home server ip address no? Also, openvpn on skyrocket indicates that it is connected as 10.3.0.6. But if I try to ping 10.3.0.6 from the server I get no response. Is that expected?

TAP provides a bridged connection so broadcasts on the server's network are propagated across the connection. For network-to-network connections this may be needed for things like dhcp and windows networking. For end users, this usually isn't a good thing because it eats up bandwidth. TUN, which is routed instead of bridged, is the better way to go.
My config only routes traffic destined for the server's LAN over the vpn connection so the behavior you see with whatsmyip is normal. Check openvpn's config file paramters to make the vpn the default route for all traffic.
See my other post. I included my configs.
Just add redirect-gateway option to your client configuration, or the server side client configuration in the ccd directory.
I have everything working. As for what att will see. Only an encrypted tunnel initiated from you phone to your vpn server. Ttl, ip options etc will not be visible to att.

Cool thanks again. I'll try updating my configs and trying again tonight. I'm sure not being able to ping across the tunnel was probably a configure issue a well.
You also need the Client to Client option enabled if you want the openvpn server to advertise routes to other vpn client devices and their associated networks. That would be another reason why you cannot ping across the tunnel if you are trying to ping another vpn device.

I'm not seeing your config files on the board here. I'm fairly new here so maybe I'm not looking at the right place. But I didn't see an attachment.
The configs are posted in my other thread.

Thank you. I'll try out the details in that post. If I have any questions I am going to post over there from now on because that post is more closely aligned with my goal and thus more relevant.
Has anyone had any luck getting a wired ethernet connection working on their device? I feel like I'm missing some minor piece of configuration that prevents me from getting it working. Here's what I've got so far.
1) compiled asix.ko, usbnet.ko and mii.ko for P5113
2) insmod above modules
3) connect usb ethernet adapter
As soon as I complete this, the following happens:
a) lights start flashing as soon as I connect ethernet cable
b) eth0 becomes a recognized interface
The problem is that I can't get the device to get an ip address. Neither a statically assigned ip address works, nor is one retrieved using dhcpcd. The strange thing is that when I run wireshark and do some port-mirroring on my switch, I see that the DHCP server is offering an ip address to the device, but the device doesn't seem to want to accept it. Traceroutes and pings to my gateway all show "host unreachable" messages.
Usb to Ethernet
Did you solve this? I am a network engineer that would love to see this fixed I have tried a couple of different ones and none of them have worked yet.
I have a (rooted) Lenovo Yoga Tablet 3 with Android 6.0.1 with broken RF interface (no Wifi, no Bluetooth...). So I tried to get up the Ethernet.
I used 3 different dongles, but no one was plug and play with this tablet (but all 3 work plug and play on other tablets...)
As it didn't come up with simply plug in, I managed the connection by adding (after plug in the dongle):
Code:
su
# as dhcpcd uses default table main and it isn't in the rules
ip rule add from all lookup main pref 1
# set up eth0 via dhcp
dhcpcd eth0
# here only ip addresses work, so for the dns I have to set the (android) resolver
ndc resolver setnetdns eth0 <MYROUTER> 8.8.8.8 8.8.4.4
Now all browsers and a ping app work fine, but messengers (Whatsapp, Telegram...) say 'no internet'.
When I connect via usb with gnirehtet everything works fine but I don't like to spend an extra PC for the reverese tethering server. So I changed the usb cable with the ethernet dongle and everything works fine until I stop the VPN left open. Ifconfig shows me that there are no packeges routet via tun0, just via eth0. Unfortunally I couldn't get up another VPN setup as all clients tried (even the android built in VPN) showed up 'no internet'.
So, has anybody an idea what I can do without the gnirehtet workaround?
