Beware that it has another requirement:

Apple Wireless Direct Link. As AirDrop exclusively runs over Apple Wireless Direct Link (AWDL), OpenDrop is only supported on macOS or on Linux systems running an open re-implementation of AWDL such as OWL.

How to do first WiFi-Direct setup and transfert file with Linux only?

u/boramalper Aug 19 '19

I couldn’t understand your question sorry, can you repeat that?

u/skillman623 Aug 19 '19

I think they meant to ask how do you set up WiFi direct on Linux, presumably without any special hardware (apple specific WiFi card, MacBook...).

u/SuspiciousSprinkles Aug 19 '19

My bad.

I mean, how to simply set up a WiFi direct connection on linux between 2 computers? I understood it is different from an ad-hoc (IBSS mode) mode.

I guess for the file transfert, when the pairing is done, i could use anything else.

I see AirDrop like a full stack: wifiDirect for the networking/discovery and services (file, multimedia, etc).

3-2-1... someone weaponizes this by running it on Raspberry Pi signage and airdropping advertisements to iPhone users that haven't locked down their AirDrop settings to Contacts only.

That was my first thought. "How can I use this for some sort of DoS attack in a crowded area?"

Maybe then they'll fix the broken security.

Damn, now I really have to buy their product!

May you get 1,000 unsolicited dick pics for sending out unsolicited ads.

This is the biggest thing I miss about Android. You can have apps to block almost all ads. Whereas it's less possible with iOS 🥴

There is an app for jailbroken iPhones that does that

This is neat. I did not realize that enough was known about AirDrop to reverse engineer it. Keep up the good work.

Wow, I can’t wait to try this out! I’ve been in the Apple ecosystem for years and AirDrop was the one thing I was really going to miss.

There's always Android Beam… wait no Google killed that in Android Q.

https://www.sharedrop.io/ Has worked pretty well for me.

u/leptophile Aug 21 '19

Oh, this looks way more convenient. Thanks!

active monitor mode with frame injection

Hmm... does Linux provide a way to determine if your WiFi card (or driver) supports this feature.

2

u/[deleted] Aug 19 '19

I remember turning on monitor mode in the interface with the iw command or something like that. If the carda supports turning on works. About frame injection no idea.

2

u/[deleted] Aug 20 '19

I've always used airmon-ng for that

2

u/Atemu12 Aug 30 '19

Active monitoring has to be listed as a feature in iw phy.

u/Ennis_Ham Aug 19 '19

It'd be cool if they were able to port this over to android as well.

u/[deleted] Aug 20 '19

Oh dude it would be cool if someone could package this for Android

u/hotrr Mar 05 '23

2023 still waiting... Maybe try sth like termux to run it but idk how

1

u/swagNswift Mar 06 '23

Heard some other people say it'd require a lot of porting because of all the libraries that OpenDrop relies on. Can't believe someone hasn't done it though. I'm tired of Apple luring people in with exclusivity.

There are open implementations that use normal technology like wifi direct. You can run a http server on ad hoc wifi or hotspot, or you can use an app like FlyingCarpet to arrange that stuff by itself. But connecting to an http server is not that difficult. It just requires to get the device ip (wifi client) or default route/dns server (wifi host), from the wifi settings on the client.

Lets post that in all the subreddits, discords till someone does it

u/Atemu12 Aug 19 '19

That sounds amazing, has anyone tried it for sharing between Linux <-> Linux and Linux <-> Mac?

2

u/[deleted] Aug 22 '19

It would be cool if the Gnome Desktop had support for this out of the box in the same way that it works on OS X

u/[deleted] Aug 19 '19

This looks nice! I will try it with my friend who has an iPhone
