Tetrd - USB Tethering & Reverse Tethering (NoRoot)

**ramencoder** · 01-24-2020, 04:25 AM

Tetrd is a simple tool that allows you to share your internet connection from your device to your PC and vice versa through a USB cable.

Tethering
Tethering allows you to share your device's wifi or mobile internet connection with your PC. You can use this if your carrier or data plan doesn't allow you to enable the built-in tethering feature of your device. Or if you have unlimited data plan, but your carrier caps your hotspot/tethering usage to a certain amount, say 7GB.

Reverse Tethering
Reverse tethering allows you to share your computer's internet connection with your device. You can use this if you're having issues with your device's wifi connection such as unstable ping or disconnections especially when playing games and your PC is already connected to the internet via an ethernet cable. It can also be used in situations where wired internet is the only available option.

Note: Some apps only check for wifi or cellular connectivity, thus will not have internet access when reverse tethering.

Network
When tethering or reverse tethering, your PC along with all connected devices will be in the same network. This means a device can communicate with your PC and other connected devices. This is useful if you want to transfer files from one device to another or if you want to access a server (e.g. HTTP server) on your PC from your device.

Note: ICMP is currently not supported so the ping command will not work when tethering or reverse tethering.

Additional Features
• No root required
• No USB debugging required (except on Windows)
• Fast link speed (200Mbps+ on some devices)
• IPv6 support (may not work on some devices)
• Up to five devices can be connected
• Configurable network settings

I am interested in trying this. How do you configure a pc to see the internet connection on the usb port ? Thanks !

Thanks for showing interest in the app. To share your internet connection from your device via USB, you will need to install the server app first on your computer. I cannot post a download link to the server app installer because this forum doesn't allow it, but you can find it by searching "tetrd.app/server" on google. If you're using Windows, you will also need to enable USB debugging before connecting your device. Once the server app is running and you have enabled USB debugging, you can now plug your device to your computer. The app will then automatically open on your device. Tap on the connect button and choose normal tethering mode to share your device's internet connection to your pc. To get more detailed instructions, you can also look at the guide page on the mobile app.

A bit of a coincidence since I was looking at this last night and sent you an email. I'll say it here too in case I sent to the wrong address or something.

It would be nice if you could do a Linux Debian release for ARM so it can be used in a Raspberry Pi. I'm using EasyTether in a Pi and it's working well but I'd be happy to try your app especially since you seem to be responsive and actively developing. I have no idea how big a task it is to produce a ARM version of the AMD64 code you have now.

Can your cell phone carrier tell you're tethering? Cause my carrier kills my upload speed so I can't stream on my PC.

What Linux distro are you using? I'll try recompiling the app for ARM using QEMU, but since I don't have a Raspberry Pi to test on, I don't know if it will work.

The app proxies the connection coming from your computer so from the perspective of your carrier, it's like your phone is the one accessing the internet and not your computer. But some carriers do some additional checks to detect tethering, so it really depends on your carrier. The app offers a three-day free trial so you can check if it works on your carrier.

I think a VPN makes it difficult for them to tell. If you're running a LAN with multiple devices then the VPN should be on the WAN port of your router, not on the individual LAN devices.

I run WireGuard with EasyTether which is a similar app to the one talked about here. That gives another cool advantage in that it smooths over the limitations of the tethering app. EasyTether and I think this app only does limited protocols. TCP, UDP but not ICMP. Since WireGuard is only using UDP, the end result is a normal complete connection.

I think that's true but I also think the anti-detection stuff that pdaNet (another similar app) does is kind of silly. I think it attempts to change user-agent strings etc to make it look like you're on a mobile device. I don't want a tethering app messing with my data. I just want a transparent pipe. A VPN is an infinitely better way to do it but I agree, you need to be a bit of a nerd to set it up.

Maybe I missed it but I didn't hear mention of this using a VPN connection till 10 posts in or so. No soap my essential adblocker from Github (other download locations don't block ads) only NetGuard uses my VPN.
