simplert's Introduction

SimpleRT

Android component:

Reverse Tethering utility for Android.

Provides a way to share a computer's internet connection with an Android device via a USB cable.

Development is still in progress, bugs and errors can occur.

FIRST RUN: check out -h option
   simple-rt -h
   usage: sudo ./simple-rt [-h] [-i interface] [-n nameserver|"local" ]
   default params: -i eth0 -n 8.8.8.8

IMPORTANT
   If you have any issues with this tool, please, provide some logs:
   - run util in debug mode (-d), connect your device
   - run "ip addr show"
   - run "ip route show"
   - store this output into issue ticket on github

No root or adb required

Full Linux and macOS support. Windows version is being researched.

Current version features:

Multi-tether. It is possible to connect several android devices into one virtual network
DNS server can be specified (custom or system one).

The SimpleRT utility consists of 2 parts:

Android part:

Implemented as a standalone service, no gui, no activities

Dependencies:
- Android 4.0 and higher.
Build system based on gradle + gradle experimental android plugin (supporting ndk). To build, both sdk & ndk are required. Create local.properties file in root dir, it should look like this:
```
ndk.dir=/home/viper/Android/Sdk/ndk-bundle
sdk.dir=/home/viper/Android/Sdk
```
build:
```
./gradlew assembleDebug
```
app/build/outputs/apk/app-debug.apk is your apk.

Now available in f-droid

A prebuilt apk can also be found under Downloads at the Github releases tab.
Desktop part:

Dependencies:
- libusb-1.0
- libresolv (usually already present in both linux and macos)
- tuntap kernel module (linux version), utun (macos version, builtin)
before build (debian-based example):
```
sudo apt install build-essential pkg-config libusb-1.0-0-dev
```
Makefile is universal for all platforms, just type "make && make install" to install it in prefix /usr/local and check /usr/local/sbin is in your PATH-variable. If you want to change the prefix path eg. to install it in /usr instead of /usr/local you can type "make prefix=/usr && make prefix=/usr install". If you don't want to install but just run it from within build directory you can type "make iface_up_sh_path=.".

Usage:

run console util as root (sudo simple-rt). The iface_up.sh file needs to be present in the application folder.
connect your android device

First connection requires some trivial steps:

Issues: Some apps do not recognize the reverse tethered internet connection due to ConnectivityManager policy. Leave the WiFi or mobile data connection active, the connection through SimpleRT will be prioritised.

simplert's Issues

F-Droid isn't seeing new releases, is currently stuck at 1.0

Can ya'll make sure that F-Droid can see it when you update SimpleRT and/or make sure it updates to the current stable release?

https://f-droid.org/packages/com.viper.simplert/
https://f-droid.org/wiki/page/com.viper.simplert
https://gitlab.com/fdroid/fdroiddata/blob/master/metadata/com.viper.simplert.txt
https://gitlab.com/fdroid/fdroiddata/issues/789

1.1 APK shows up as 1.0

The .apk attached to the 1.1 tag, if installed, shows up as version 1.0. Looking at the package itself, it seems versionCode and versionName are set incorrectly:

package: name='com.viper.simplert' versionCode='1' versionName='1.0' platformBuildVersionName='N'

As there already was a v1.0 before that, versionCode must have been increased – and versionName should reflect the real version number 😸

So may I suggest to correct that? And when attaching the fixed .apk, please leave it an .apk and do not ZIP it again. Thanks in advance!

How to solve "bulk transfer error: Input/Output Error"?

Once I accept on the android device I get:

libusb callback registered!
Device supports AOA 2.0!
Sending identification to the device
...
...
Found accessory 18d1:2d00
accessory connected!
libusb callback deregistered!
net.ipv4.ip_forward = 1
bulk transfer error: Input/Output Error

tun returns File descriptor in bad state and that signs it's ready:

cat /dev/net/tun
cat: /dev/net/tun: File descriptor in bad state

Any ideas how to solve issue?

Why did you stop developing this?

It is a nice project, and you could add proxy support.

Cant set up Tun Interface

Hello , when i try to start the program i get this error:
[tom@tom-pc simple-rt]$ sudo ./simple-rt -i enp5s0
[sudo] Passwort für tom:
starting network
configuring:
local interface: enp5s0
virtual interface: tun0
network: 10.1.1.0
address: 10.1.1.1
netmask: 24
nameserver: 8.8.8.8
Error: either "dev" is duplicate, or "10.1.1.1/24" is a garbage.
Unable set iface tun0 up
Unable to start network!

It maybe really easy to fix, but i dont know why it isnt working.

VPN doesn't start for a long time or until I change USB from charging to Transfer Files or MTP

This might not be relevant in the latest version, I'm running version 1.0(2016/09/19) from F-Droid.
I'm running LineageOS 15.1 Android Oreo 8.1.0 Kernel 3.4.113.

If I leave the phone and wait for the VPN popups, it takes a VERY long time
I started every time with my phone connected via USB, phone screen permanently on and phone in high-performance mode.
When I start simple-rt from my Linux desktop (firewall disabled), initially nothing happens.
If I just leave the phone for few minutes eventually the popups come and I accept them as per the screenshots. Then I get the key icon at the top.

Making the VPN popup happen immediately
I can make it connect immediately by going into the USB menu of my phone in settings, then changing USB from charging only to either File transfer mode or MTP mode.

Then I have a problem that seems the same as this #49

I ran it in debug mode. I let it run for 75 seconds but it seemed to be going around in circles, so I stopped it with Ctrl-C. Here's the beginning of the log.

debug mode enabled

apk traces

i deleted ur apk, but every fucking time i plug in usb cable fucking dialog box of ur fucking app pops up.

Automatic stopping of service when USB cable is unplugged

It would be nice if it could do that since the other tethering program (gnirehtet) does that.

Problems assigning routes; manual intervention required

Hello,

I've been using SimpleRT apps, but on my phone, a Samsung Galaxy J1 (SM-J100H) running Android 4.4.4, I have to run manually from a terminal emulator:

   $ su
   $ ip route add default via 10.1.1.1

in order to be able to connect the phone to the PC network. It seems to be a problem with Android 4.4 because in a Nexus 5 running Android 7, the same default route created by SimpleRT app works fine.

Take a look at gnirehtet

I was wondering if you'd taken a look at https://github.com/Genymobile/gnirehtet and if you had an opinion of which project had better implementation/features. Just some friendly cross-pollination, thanks!

apk leaves this shit

Issue with it and Bleach: Brave Souls

When I am tethering with it and trying to play the game I mentioned, it complains about network connectivity issues every so often.

Drop tun/tap requirement?

Have you considered using the "fake network" code from VDE ( http://wiki.v2.cs.unibo.it/wiki/index.php?title=VDE_Basic_Networking#Slirp:_a_virtual_NAT_router_as_a_process ) as an alternative to requiring TUN/TAP?

not work...

hi,
my simplert system is not worked,ubuntu17.10 and android 4.4.4,vpn can be connected,but my phone's webbrowser and other softwares cann't connec to internet...
thx!

Iptables: No chain/target/match by that name

I had the error as title "Iptables: No chain/target/match by that name"
I finally found it was iptables "comment" keyword that was not supported. I had to add it in the kernel like TUN/TAP. With gentoo I added:

NETFILTER_ADVANCED=y (menuconfig "Advanced netfilter configuration")
NETFILTER_XT_MATCH_COMMENT=y (menuconfig ""comment" match support")

I like the automated way of connecting on the Android side.

It would be nice to have a way to access internet with proxy. I don't know much about networking and android programming. Would there be a way to support it on the pc side ?

Thanks for the nice software

It does not work

I download zip file from this site, extracted it, go to directory simple-rt-cli and run "make" in terminal, then i execute "sudo ./simple-rt" in terminal on my Linux Manjaro computer. I also download apk file and installed it on android tablet. I connect via usb cable android and computer. Web pages did not opens on android.

Slow download speed

First of all, thanks for you great tool!
I've only got one issue... I only get download speeds of less than 300 KB/s on my phone when connecting it though SimpleRT, although my internet connection can handle up to 2 MB/s.
Am I doing something wrong or is this normal behavior?

I'm using Linux with 4.4.0 kernel on my computer and Android 6.0 on my phone.
I compiled the command line tool myself and used the provided apk.

Google play doesn't update apps

In play market work all except update/install app.
It just shows message "searching network..."

How much flowrate do you have? why not use wifi directly, hah

Allow a way to select IP addresses/ranges

great app but more control over the ips it hands out would be a nice touch.
Would like to be able to give a phone a dedicated 10. ip instead of the kinda sequential ones you hand out now, and any other devices will get a different non dedicated ips.
I think this is better than gnirehtet because its runs on linux boxes with two network cards with no problems, gnirehtet relies on adb which doesn't like two network cards in linux at least my configuration of them.
SimpleRT just works.

Please explain how to install / use this app

Im relativly new to linux and I really need an easy explanation of how I install this program and how I use it.

I have a Huawei p8lite, of which the WiFi isnt working, so I thought, I could use my computers connection on it to install all necessary apps. Because, it isnt rooted, I only can use this one app in the playstore which doesnt work for me, or simpleRT.

How do I install it? Do I have to download it? where can I execute? I already have the apk from fdroid on my phone, but I dont know how to go on.

Hope somebody with more knowledge than me can explain me.
Thanks

strange behaviour respect to gnirehtet

I'm on a LG Nexus 5 AOSP ROM Android 7.1

I was testing methods for reverse usb tethering and found the following:
With gnirehtet, most apps (except google apps) work without having to turn data nor wifi on. For example Whatsapp and Telegram work without issues.

With SimpleRT, I get the conection, I can ping machines in my local network, but some apps work perfectly (dont need wifi nor data) and some others don't (need wifi or data). For example, Whatsapp works and Telegram doesn't.
The question is: why is that if both use VPN connections? Is it fixable?

A different minor issue with SimpleRT, sometimes after disconnecting usb the VPN service stays running, and must be closed manually.

Device is not support accessory!

sorry, new issue :)

Makefile for Openwrt

Hi vvviperrr,
I read that you have your code running in OpenWRT too. Could you add a Makefile and some instructions to compile it?
I'd really like to try SimpleRT on a small device.

SimpleRT over VPN interface

I'm looking into implementing a real VPN connection to a server and tether that interface so the server can policy route packets to the Android devices and use them as exit nodes. It's a no-root-required project for me, so i can't use the iptables already on the android, but instead need to find a way to route or forward the packets that reach the VPN interface to the default gateway and pass them back.
Would you have any pointers for that?

Routing not working, unusual IP addresses

Hi, Thanks for sharing this project.

I installed SimpleRT 1.0 (2016/09/19) on the Android 4.4.4 with 3.0 Kernel, via F-Droid and compiled and ran the cli as root on the PC.
When i plug the phone in, simpleRT asks if it can start the VPN, I say yes.

Afterwards I only have one item in my routing table.
ip route show shows 10.10.10.0/30 dev tun0 src 10.10.10.2
ip addr show shows tun0 is up with ip 10.10.10.2/30

The problem with that is the cli gets IP 10.1.1.1 which is not reachable by the phone's routing table.
I tried adding a route on the phone:
ip route add 10.1.1.1 via 10.10.10.2 dev tun0
And on the PC
ip route add 10.10.10.2 via 10.1.1.1 dev tun0
But they still can't ping each other, and of course the phone doesn't have a default route, so can't connect to the internet either.

I changed iface_up.sh as follows

#TUNNEL_NET=$4
TUNNEL_NET="10.10.10.0"
#HOST_ADDR=$5
HOST_ADDR="10.10.10.1"

Now theoretically they're both on the same subnet etc, but still can't ping each other and the phone still can't connect to the internet.

I've confirmed iptables-save on the PC and on the phone both show input and output have accept as the default action and there's nothing there that would block any traffic.

1.0 git tag has a comma in it

The 1.0 release is actually marked 1,0 with a comma instead of a period:
https://github.com/vvviperrr/SimpleRT/releases/tag/1%2C0

That breaks automatic version parsers, like in F-Droid:
https://gitlab.com/fdroid/fdroidserver/issues/198

Could this be retagged with a dot instead of a comma?

Is there any way to share the Reverse tethered internet through Mobile Wifi Hotspot?

When i tried this, i couldn't get internet on the second device which is connected to this SimpleRt device through Wifi Hotspot.

Any idea how to achieve this?

Launch service over adb?

Is it possible to start the service directly without requiring physically detaching and re-attaching the USB cable?

In an automated lab environment we may be rebooting devices remotely and managing the state of the device over adb and it is pretty critical to be able to start/stop remotely. It feels like I'm pretty close but may be missing something:

$ adb shell am startservice com.viper.simplert/.TetherService
Starting service: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.viper.simplert/.TetherService }
Error: Requires permission android.permission.BIND_VPN_SERVICE

$ adb shell pm grant com.viper.simplert android.permission.BIND_VPN_SERVICE
Operation not allowed: java.lang.SecurityException: Package com.viper.simplert has not requested permission android.permission.BIND_VPN_SERVICE

Stopping it remotely (and cleanly) is pretty easy:

adb shell am force-stop com.viper.simplert

Issue with DirecTV App

I disabled the Wifi since I am tethered to my PC via a VM (until Windows support is added). When I try running the DirectTV App, it complains that I don't have Internet access even though I do. Also, I cannot access my DVR via it.

Not sure if USB debugging needs to be enabled, but I tried without and with.

Tunneling unsuccessful

Hi :)

There is the VPN prompt in the phone. I have mobile network enabled. curl example.org works via adb. But as soon as I accept the prompt, curl freezes, no result.

With version 1.0 from F-Droid (could #37 cause an issue? #37)
PC counterpart : 20190906_9b63526-1

cli.log.txt
ip-route.txt
ip-show.txt

name of the network interface

u think everyone got default name like eth0? may i ask why? in my case its enp0s8 so eth0: error fetching interface information happens

Issue with it and Lubuntu

When using the debug output parameter, letting the log that's display grow and pressing CTRL+C, it froze the OS on me.

Have u resolved the MULTIQUEUE issue on the TUN/TAP ?

Hi !

Я видел ваше сообщение по поводу MULTIQUEUE TUN/TAP на линьюксовом форуме. Удалось ли разобраться с проблемой ?

read_usb_packet failed: Entity not found

SimpleRT stops working after device reboot

Hi,

I am using SimpleRT for a Samsung Galaxy S7 with Android Version 7.0 connected to a Raspberry Pi 3 with Raspbian as the Host.

I have downloaded your provided apk and installed it via adb install

Reverse tethering is working fine until I restart the android device. After the restart, SimpleRT on the Pi is telling me that reverse tethering is working again but the android device is unable to get an internet connection.

This problem is resolved after I enable wifi on the android device, let the device connect to a wifi hotspot and then disable wifi again. Afterwards, reverse tethering can be used again.

This is the complete rt debug output.

[NOT AN ISSUE] AUR package

Hi!

I'm tired of making systemd units for simple-rt every time, so I decided to make an AUR package for it. Any Arch Linux user now can easily install it this way:

yaourt -S simple-rt
sudo systemctl enable simple-rt
sudo systemctl start simple-rt

https://aur.archlinux.org/packages/simple-rt

I had to make dirty hack to replace eth0 interface name in iface_up script, but in my case it works fine. I can add you as co-maintainer if you want so.

Thank you for your work 👍

multiple device support

I see in iface_up.sh that the host and device addresses are "hardcoded in android part" so how do we get multiple devices working with this? Thanks!

Proxy support

Hi! It's possible add an ability to work with Orbot/I2P networks??
