usbnet direct host-2-host with usb 3 passive cable - ?

[lejeczek]

hi guys.

Searching vastness of the Internet does brink a definite 
answer or I failed to find one, so I thought I'll ask fellow 
Fedorians.

Would anybody know of perhaps has tried, to hook up two 
boxes directly via a passive usb 3.x type A cable and have 
it as "regular" ethernet connection?

many thanks, L.

You can't do that.  For USB, one side has to be the host and the other a 
device.  PC USB ports don't do device mode, only host.

What I've just noticed for the first time is, config eg.:
..
[Peer]
..
AllowedIPs = 10.0.0.2/32, 10.0.0.226/32
Endpoint = 10.1.1.224:51852

[Peer]
..
AllowedIPs = 10.0.0.3/32, 10.0.0.226/32
Endpoint = 10.1.1.225:51853
> $ wg

interface: wg0
   public key: c+gJArxYd8+=
   private key: (hidden)
   listening port: 51851

peer: K/=
   preshared key: (hidden)
   endpoint: 10.1.1.225:51853
   allowed ips: 10.0.0.3/32, 10.0.0.226/32
   latest handshake: 16 seconds ago
   transfer: 124 B received, 2.14 KiB sent

peer: /KidNfhqgP/+c3A=
   preshared key: (hidden)
   endpoint: 10.1.1.224:51852
   allowed ips: 10.0.0.2/32                # !! no 
10.0.0.226/32 ?
   latest handshake: 3 minutes, 15 seconds ago
   transfer: 180 B received, 92 B sent

That is probably why only 10.0.0.3 with secondary IP is 
"reachable". Right?
If that is by design and expected - why is that and how to 
make a "floating" IP work if that is by design?

thanks, L.

I would think a passive USB cable between PCs would be liable to break
things due to wiring two power supplies directly together.

Historically, the USB cables that let two PCs network together were a
special device.

This needs a special cable and a linux driver for your USB hardware.   I
think the original
spec was intended to rid with world of serial cables, e.g., when using a
2nd pc as a
terminal for debugging.   That didn't work because there are still many
older devices like
Ferrups UPS's that outlast half a dozen modern UPS's but use serial ports,
so we all
went out and bought USB to serial adapters,

For higher than serial port speeds there are active cables but you need
linux drivers.
In many use cases (systems are close to a switch with empty ports or one of
the
systems has a spare ethernet port) you are better off with a USB to
ethernet adapter
because there are more choices that will work with linux.

What does this have to do with USB ports?
