OT: Connect two computers with linux with wlan, but without any router

[Hans <hans.ullrich@loop.de>]

Dear list,

just a question: Is it possible, to connect two computers with linux via wlan 
without any router?

I know, it is working with ethernet cable and crossover-cable. 

But is this possible with wifi, too? My idea was working with fixed IP`s and 
give computer A the IP-address from computer B as gateway, and the other way 
round. Of course I my thinking was wrong (otherwise it would have been 
worked).

I saw several descriptions for Windows, but I am looking for a general 
solution, as I would like to connect also other devices (like an Android 
cellphone).

You may ask, why I want to do this. Explanantion: I want to transfer video 
from a drone to the computer with wlan, but the router causes a slight delay 
between source and target (which is normal). So I aim to  eliminate the brake.

The protocol and software I am using on the computer is RTMP with NGINX and 
VLC, which is well working - except the little delay.

Short for long: Is there an EASY way, to connect both hosts? Is it possible at 
all with linux?

Thanks for any hints!

Best

Hans
