[Q] How to modify MAC address without reboot? - Nexus 7 Q&A, Help & Troubleshooting

I have rooted my Nexus 7. Currently, the only way to change my MAC address is the following:
Code:
$ echo -n <MAC> > /persist/wifi/.macaddr
Using busybox ifconfig seems to work because new HWaddr is shown but in fact it doesn't - Settings->About tablet->Status shows old Wi-Fi Mac address. Additionally I cannot connect to AP any more. OpenWRT says:
deauthenticated due to local deauth request
Click to expand...
Click to collapse
I can write a script to automatically write new MAC to /persist/wifi/.macaddr and reboot, no problem, but I would prefer to avoid rebooting.
Kernel version 3.4.0-g03485a6, Android 4.4.4, Nexus 7 2013 Wi-Fi only.

Is this possible?

Has anyone ever got this to work? I'm searching on a way to have my MAC address changed upon booting the device and keeping it that way. Using ifconfig/busybox just allows you to change the MAC on that "boot session" and reverts back when you disconnect from an AP. I want to change my "stock MAC" from the get-go so that if I disconnect from an AP, it wont go back to the actual one. There is no /persist/wifi dir on my Nexus 7. Anyone who has done this before who can tell me how to do it?

AdHoc wifi + HTC Dream

Hi, all.
I'm using my laptop in AdHoc mode, all device based on winmobile, detect normally my adhoc point and connected so good.
But my g1 do not find AdHoc point
Someone tried to link android + adhoc?
If you still got the Problem and your phone is rooted take a look here:
http://blog.joint.net/2009/07/connecting-android-phone-through-adhoc.html
G1 does not support ad-hoc out of the box. There are solutions for rooted phones but none of them are perfect at this point.
Hi
I have found the solution. I am using Ubuntu 10.04 and Using superfroyo2.2 on my HTC dream. I can connect to wifi adhoc network of my PC and enjoying internet on it.
I have attached the zip file. Please extract the file to get tiwlan.ini and wpa_supplicant.conf file. Replace your mobile's file with these ones and enjoy ad-hoc wifi.
You can use below commands, with mobile connected to PC via usb to replace the files:
adb shell
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# exit
> adb push tiwlan.ini /system/etc/wifi/tiwlan.ini
> adb push wpa_supplicant.conf /data/misc/wifi/wpa_supplicant.conf
> adb shell
# mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
# exit
I was using ubuntu bash and I placed both files in the tools folder of SDK. and then I ran the commands from that directory so that no path issues arise.
One more thing, You should create adhoc wireless with SSID iBM and leave it open without security key.
NO ROOT required!! - I am using MyTouch 4g with android 2.2.1
This is for anyone using Android who wanted to use Ad Hoc network to connect to internet (Android device connects to PC/laptop which is connected to internet) and couldn't because android doesn't support it ( Not rooted ). Here is a solution that DOESN'T require rooting the phone. I am running Android 2.2.1 and have no knowledge on compatibility despite my 2 days of research and eventual success.
Things you need: Windows 7, Android device and Connecitfy software ( link below... free version works just fine )
1. Update drivers for Ethernet and WiFi adapters in device settings... windows virtual WiFi miniport adapter should show up in the device list
2. Now startup Connectify: Create hotspot and choose password (uses WPA) and then start hotspot.
3. Now on your android device this network name should show up because its not Ad Hoc anymore. Its like a virtual router or hotspot.
4. NOTE: If google services fail on the android device. Go to account and settings and then sync now for your google login. Once synced, try opening android market and if it says authentication failed, try opening market two or three times more and it should eventually accept. If it doesn't... go find a solution and add to this post or create a blog.
5. Enjoy...hey hey wheres my treat!!

Device name in WLAN

Hi folks,
can i change the device name of my HTC Hero anyhow, so that in my router's overview it shows the name of it, like it does with laptops / PCs?
I know its possible with bluetooth, but i havent found any option for doing that concerning WLAN.
I didnt root my device, otherwise i would have probably tried the commands which i would use for my Ubuntu laptop:
sudo echo "newname" > /etc/hostname
sudo hostname -F /etc/hostname
and edit /etc/hosts accordingly.
Anyone knows a solution for me?
Best regards,
kapen
Please, anyone?
Or could anyone, who has a rooted Hero, go and take a look whether the files /etc/hostname, /etc/hosts and the command "hostname" exist? Or perhaps even write something in these files, i mean it wont do any harm as you are just writing sth to an ordinary text file.
If i'd have root, i'd do it myself, but for now there are no benefits for me which would push me to root and i don't want to lose my warranty for nothing.
Help is very much appreciated!
most routers let you do this on the router....
I know when i hook up to my thompson router and set a static IP address, it lets me name the device... Hardly worth hacking the device for really.
Bump
I'd like to be able to do this as well, without having to use a static IP. This can be done with symbian, winmobile, java and other types of phone not to mention internet tablets, laptops etc. Why not an Android phone?

True. But most routers isnt my router, its not able to do that. And neither do i want to set a static IP on my Hero, because i'm using it with several other WLANs.
fair enough.
I just thought as there is no way that anyone seems to know of on the device, that it may be an alternative.
Ya your right.
I just thought anyone knew a solution for me. I mean its a system running on linux and i ought to be able change that kind of stuff... just don't know how :\
Heureka! It worked just the way i suggested
If you have a rooted device with busybox!, get that handy adb file and do:
Code:
1. adb root
2. adb remount
3. adb shell
3.1 cd /etc
3.2 echo "Hero" >> hostname
3.3 echo "127.0.0.1 Hero localhost.localdomain localhost" > hosts
3.4 echo "127.0.1.1 Hero" >> hosts
3.5 hostname -F /etc/hostname
Voila. Though, you'll get an error when you do "hostname" now, because something in busybox is wrongly linked against a library which doesnt allow resolving hostname by IP, but other devices (such as my router) will now display "Hero" as device name.
Side note: my only intend for doing this was, that my router WAG54G2 (Linksys by Cisco) didnt work correctly with my Hero, meaning i got a lot of connection aborts in WLAN and often could not reconnect afterwards. That seems to be solved now!
Edit:
With the method above, you''ll lose your Wlan name after reboot. You need to add a line to the init startup scripts to perform a "hostname -F /etc/hostname" on every boot. This can be done in the file /init.rc or, if you have the MoDaCo Rom, in /data/init.sh

HOWTO: Ubuntu USB reverse tethering

def:"Reverse tethering" : sharing your PC's internet connection with your Android phone.
This is suppose to work with any rooted Android device with the latest of Busybox. I own an Atrix and I use Ubuntu, and it works. If you own X and use Y, I don't care . It is also suppose to work with any USB tether-able Android device (like in proper, not the kind where you need to download an app for your PC to set up a SOCKS proxy of some kind).
I also use the Gingerbread ROM leaked for AT&T. This was done on Ubuntu 11.04 Natty, but the principles stay the same.
Let's get on with, shall we:
INSTRUCTIONS
Install Firestarter and DHCP server
sudo apt-get install firestarter dhcp3-server
Connect to the internet
Like you normally would. If you connected via WiFi, your connected device would probably be wlan0, if via ethernet - eth0, if via dialup - ppp0. If you are unsure, click on the Network Manager icon and click on Connection information. Otherwise, run ifconfig to see which device has got what IP address (to give you a hint as to what network device your PC is using).
Start USB tethering on your Atrix
Plug in the USB cable in your Atrix.
Under Settings -> Wireless -> Tethering & Mobile Hotspot -> USB Tethering checked.
Your Network Manager will try to get an IP address (and will probably succeed). Click on the Network Manager icon (probably the icon has changed to an ethernet port to signify that you are connected via USB) and click on "Edit Connections".
Under the "Wired" tab double-click on USB0 to edit it
Under the "IPV4" settings click on the "Routes" button
Check the "Use this connection only for resources on its network"
OK, Save
You'll see the Network Manager icon will change back to its previous icon.
Configure Firestarter
Run firestarter
If it is your first time to start firestarter, it will prompt you with the First Run Wizard. Otherwise, click on Firewall -> Run Wizard
Click Forward to get past the intro screen.
In the drop down box, select the device you are connected to the internet with.
Click forward
Check the "Enable internet sharing" option
On the checkbox, select the "Unknown Device (usb0)" as your Local Area Network device
Check the "Enable DHCP for local network" option
On the DHCP server details, select the "Create new DHCP configuration:" option
Click forward
Uncheck the "Start Firewall now"
Click save.
Great, so Firestarter is set up. But, it saves the dhcpd.conf file (Natty specific? I don't know) in the wrong directory (/etc/dhcpd.conf instead of /etc/dhcp/dchpd.conf).
sudo mv /etc/dhcpd.conf /etc/dhcp/dhcpd.conf
Start the Firestarter firewall (in Firestarter, press CTRL-S)
Configure the Atrix
2 Options:
1) While the device is connected via USB (and Applications -> Development -> USB debugging is enabled)
sudo adb shell
su bash
netcfg usb1 dhcp
2) Run in your terminal on your phone:
su bash
netcfg usb1 dhcp
If nothing failed, then everything worked. The principle is this : IP Chains between USB0 and <internet connecting device> (set up by Firestarter) with DHCP server running. This may not be the most über geek way of doing things but is sure point-and-clicky-easy-ish.
Et voilà, sweet reverse tethered nettubes...
No Enable DHCP checkbox
while i try everything .... i m stuck at the part where the 'Enable DHCP for local network' checkbox is inactive due to 'Chromium cannot be run as root'....
i dont know why this error kindly help me with this....
How is Chromium even related to DHCP and/or firewall settings?
failed
Code:
action 'dhcp' failed (Bad file number)
I'm using LightJB 1.2 Rom with CoCore-CWM 6.2
Unfortunately my Network Manager hasn't succeed when I turned USB Tethering checked on Android since I've upgrade ubuntu from 14.04 to 16.04.

[Q] MAC Spoofing on SGS5?

Hey guys, I'm trying to set up my phone as a StreetPass relay for my 3DS. I can't seem to change the MAC Address, however.
I'm running a stock SM-G900W8, rooted, SIM Unlocked, with BusyBox installed.
I've tried a handful of MAC Changing/Spoofing apps, and I've tried using the terminal to change it with BusyBox, but I've had zero success. It simply won't change...
Any suggestions or information would be great, thanks!

Can't change your MAC address with busybox? That is rather unlikely. But you didn't describe what busybox commands you used, what apps you tried, how you checked your MAC address or much else. Making it impossible to tell what went wrong for you. It certainly works on my S5.
Note that the the Android settings menu about device is only reporting the native hardware MAC address. That isn't necessarily what the WAN network actually sees. Discerning your real outward facing MAC address is best done by from your router menu, ethereal, et cetera.
List your interfaces and identify your WAN route, e.g.
Code:
$ su
# busybox ifconfig
Your WAN interface will probably be wlan0. Once you identify the correct interface, note the active MAC address i.e. HWaddr. At this point, it probably agrees with the default settings menu information.
Change your session MAC address
Code:
# busybox ifconfig wlan0 hw ether 00:05:1A:25:55:02
Confirm the change
Code:
# busybox ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:05:1A:25:55:02
Done

[How To] Http Proxy on Amazon Fire TV Stick (non root)

Hi,
I just had the problem of being behind a Http/Https proxy and there is currently no option available to set this on the fire TV Stick.
Android offers this option at least since version 4 by default but they must have deactivatetd this feature intenionaly (region rights and such things).
But it is still possible.
1. Setup your AFTVS on a normal Wifi with internet connection ( if not already done)
2. Activate Apps from unkown sources and ADB
Settings --> System --> Developersoptions
3. Make sure your are connected to the same network as your pc.
4. Sideload following app:
Code:
AndroidProxySetter:
github.com/jpkrause/AndroidProxySetter/releases
How To sideload:
aftvnews.com/sideload/#more-7959
5. Start the App over adb on your pc:
Code:
//connect to device
adb connect 192.168.1.184:5555
//check the connection
adb -s 192.168.1.184:5555 get-state
//start app
adb -s 192.168.1.184:5555 shell am start -n tk.elevenk.proxysetter/.MainActivity -e host 192.168.56.1 -e port 8080 -e ssid PrivateWifi -e key Passw0rd
Where u would replace the device ip, host, port, ssid and key with the settings of your network.
Please mind that ur on a linux based system and everything is case sensitiv.
For more options look here:
Code:
github.com/jpkrause/AndroidProxySetter
5. Now, if everything is fine some little popups will be displayed and at last it should say connected.
6. Going back to the home screen and Done.
Known issues: After some major updates you will need to set the proxy again, so just repeat step 4
It should also run on the normal AFTV but i got none so i can't test it.
All Credit goes to JPKrause who wrote that little app, I just happend to find it
Update 21.06.2016:
With Fire Os 5.2.1.0 it seems like you cant start adb on the device itself so you have to start the proxysetter over adb on your pc.
This "new" way doesnt require to install the terminal emulator anymore and its actually more comfortable.

Hi,
well I guess the AndroidProxySetter doesn't cover any way to use PAC files.
But you can actually open your pac file with an editor of your choise and extract your proxy settings from the containing functions.

Hello, I have this working on a Fire Stick, I ran the commands on a Fire TV and is not working. Anyone has this working on a AFT (no stick)?
Any help is appreciated.
Thanks.
edit: it not working anymore on my fire tv stick, I see the connection going to the proxy but in the screen it says invalid_geo_ip, somehow they manage to get my original ip. My gf is american, and we are abroad, this was the only way to watch amazon content. Sad. I'll try to get a vpn instead, but this proxy setting was easy configuration.
Hi mastodonian,
in my case it still works like a charm on the AFTVS. I just tried it over a vpn that my home server provides, but the tv stick then says something about geo restriction even though its a german vpn. I suppose they are doing some kind of deep packet inspection or they got an ip blacklist.
Can't say but eventually the proxy you are tring to connect uses internally a vpn or is on a blacklist.

its pretty simple just do the following
Download adblock plus and install it on your firestick - use the power of google or an app store on your fire stick to get it
Download this app to your pc - https://github.com/jpkrause/Android...d/v0.1.3-alpha/proxy-setter-release-0.1.3.apk
Adb this app to your firestick by (assuming you have adb installed if not google howto)
enable adb on the fire stick in dev options if not already done so
adb connect 192.168.1.1 (change the ip address to your firesticks)
adb devices (you should see a list of devices connected if adb is working with your firestick ip address and port number)
adb install (then drag and drop the apk file into the command window - This will auto complete the path of the apk to save you entering it manually)
once the apk is installed
Code:
adb -s 192.168.1.1:5555 shell am start -n tk.elevenk.proxysetter/.MainActivity -e host localhost -e port 2020 -e ssid MyWifiName -e key MyWifiKey
Starting: Intent { cmp=tk.elevenk.proxysetter/.MainActivity (has extras) }
Change the ip address in the above code to your firestick ip address - the numbers after the : is the port address - it should match what you saw when you typed adb devices
Change the ssid to your wifi name and key to your wifi password
you will get some pop up windows on the firestick telling you if it has succeeded or you have errors
next open adblock plus and enable adblocking
restart the firestick
open adblock plus again and you shouldnt see the warning about it cannot manually set the proxy at the top of the screen
load up an adblock test website to test its working
Thank you for making this method clear and easy. However, even though I get the successful messages and the proxy chnages to localhost and the Port to 2020, Ad Block Plus still shows the "please configure manually" message after reboot.
Testing on some apps, the ads are most definitely not blocked!
Any suggestions?
Thanks for malking this app , I just have a problem , netflix connects directly and not through the proxy , any idea how to force connecting through proxy ,
It works perfect
I bought FireStick today and it wouldn't let me connect to Amazon as my ISP has made mandatory to use HTTP proxy.
I followed your step wise instructions and it worked. Thanks a ton
Hello,
Thank you for this! One issue: I'm unable to disable to proxy via adb... is there a specific way to do this? I've attempted to uninstall the apk file and clear data, but it still remains connected to the host.
Any assistance would be greatly appreciated!

Hi,
I actually had to do this myslef recently so what i did was just remove the network via the GUI and add the network again.
If you have to do this over ADB you should try to remove the network and add it without proxy flag

Well I have to clarify i did not make this app i just found it and put it to good use
On the issue i cant really say how to force him using the proxy. This method just configures the android intigrated Wifi network stack that supports proxys since 2.X is suppose. If an app like Netflix detects this, then u need an other method.
For windows i got an app called Proxifier, but until now i didnt find anything similar for android.
Only alternativ solution for your problem I can think of would be to configure your Accesspoint with a VPN on a second virtual network (well that's how i would do it).

Not sure if anybody is still interested in this, but I recently uninstalled the apk and was unable to install it again getting the following error: Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]
The solution is simple! The latest version of the FIreTV OS includes a proxy setting!
Just follow Step 1. in the instructions here: Blocked
The original instructions are posted on the Amazon appstore -> Appstore Blogs -> Viewing Secure (SSL/HTTPS) Traffic From Your App on Fire TVs Running Fire OS 6 on November 02, 2018
Since I've been blocked from posting a URL, here are the slightly modified instructions:
Setting a proxy on Fire TV
Bring up the Developer Tools Menu by one of the following two ways:
Remote: 1) Press and hold the Select and Down buttons for five seconds release and then 2) Press the menu button
ADB: adb shell am start -n com.amazon.ssm/.ControlPanel
Select Network Proxy
Select Manual
Enter your proxy IP address
Enter your proxy port
Click Save
Enjoy!
Hi All,
These proxy setting were working for me until the last update on OS 6.x and OS 7.x. The Developer setting app crashes on selecting save on the Network settings and the IP/port info is not saved.
Is someone else facing same issue.. Any work arounds?
Try this. It worked for me.
Use this .apk AndroidProxySetter. Install and follow the commands. It will route Network traffic to Charles proxy.
