At my university, the lab computers are locked down and won't allow the installation of Android's USB drivers. This prevents adb from connecting to the ADP1 via USB, but I can use another computer which does have USB permissions and use
Code:
adb tcpip 2222
to restart adbd in TCP listen mode on port 2222. Then, on a lab computer I can connect to the ADP1 using
Code:
adb connect <IP>:2222
and install packages, open a shell, etc.
My question is, how can adbd be preconfigured on the ADP1 to listen on a specified port on boot, instead of waiting for a USB connection and the above two commands?
This is "insecure" but it doesn't matter because the lab computers and wireless network are private, and the ADP1 has no SIM card and connects to the internet only via WiFi.
It seems that one way to do this involves editing the boot image to modify init.rc --- I'm prepared to do that, but I'm hesitant to spend the time trying it because I can't find any documentation saying what port adbd will listen on by default, or if it will listen on TCP at all.
tl;dr: Instructions on how to start adbd on boot in TCP listen mode? Thanks.
Did you find any answer to this? anybody knows how to enable it directly on phone without usb cable?

"By default, you won't be able to use adb over wifi, using this module/adbd. But if you set the persist.adb.tcp.port system property setprop persist.adb.tcp.port 5555 it will cause adbd to listen on the specified port so you can use adb over both usb and wifi. Note that adb over wifi is insecure and not recommended. Anyone on the same local network could potentially connect to your nook."
Maybe this will help you?
Not working

Thanks, but it didnt work. I tried the command in su mode, even restarted the adb service with stop/start command, no error but still can't connect to device over wifi. I can ping the device, so the connection is there. Any idea?
Solved
I finally solved the problem. these are the commands to enable adb over wifi:
Code:
setprop service.adb.tcp.port 5555
stop adbd
start adbd
and to disable it:
Code:
setprop service.adb.tcp.port -1
stop adbd
start adbd
I assume you need su access to run it. I tested it and its working.

[/CODE]
setprop has sucefully executed - no problem
how to restart this service ?
stop/start shows bad command or filename - which means command not found what is true since there is no shell command named start or stop

It worked for me. you can use my Widget to do it and see if it work or not, search market for "ADB over Wifi"

Hy!
I found my way of doing the same thing...
You have to enable dropbear ssh server on your device, and then you can forward the port 5037 (where adb listens by default on localhost only) to your computer trough ssh from your computer.
From your linux box, you can do this with this command:
ssh [email protected] -L 5555:localhost:5037
and then (but keep the ssh session open):
adb connect localhost
that's it
(note that you have to enable usb debugging for this to work!)

NON ROOTED PHONE
I am trying to create to backup of all application in android but I don't want the users to connect to USB even for the first time.
okay let me first explain what happens when we connect our phone with USB to ADB client
0. USB Debugging mode is enabled in the phone.
1. The phone is connected to PC using a USB cord.
2. We run
Code:
adb tcpip 9999
command from cmd with ADB already installed.
The above command helps now switched the abd demon (adbd) inside the android phone to listen through TCP-IP protocol
3. now we can disconnect the phone from the PC
4. using a terminal emulator application we can now fire the commands
a)
Code:
adb connect localhost:999
b)
Code:
backup -all -f /sdcard/dev/bck.ab
now a backup pop-up will open up, you can simply click backup button.
Now we can anytime execute the command in 4.a and 4.b util the user restarts the phone or
but the problem is I wish to execute
Code:
adb tcpip 9999
without PC. Can someone suggest me how to approach this problem. From where should I start reading or there is some existing application that can do this on a non-root phone.
Good morning,
This is my first post so please be gentle. This forum was recommended to me by a friend.
I am looking for an application, or someone who could create an application that would block the ability to transfer files from Kruger&Matz tablets via a usb cable. Tablets are used for training purposes and we don't want participants to be able to download files to their computers.
If anyone knows of such an application and could recommend it (it may be paid), I would be grateful. If it doesn't exist, and someone here can create it, we'll pay for it.
If you need any specific details, I'll try to provide them. Unfortunately, I'm not an IT specialist, so it's hard for me to present all the data that may be needed at once.
If tablets are rooted and USB Debugging enabled you simply disable USB services like MTP and ADB by means of ADB:
Code:
adb devices
adb shell "su -c 'setprop sys.usb.config ""'"

We can't root them, have you ever rooted this model?
Of course not because I'm using Google Pixel phones.
