Re: Ethernet via USB cable

Hi David, 

  So do I need special USB Ethernet hardware to configure a network
 between
  two OpenBSD hosts connected together via USB, if not, which manpage 
did
 I
  missed?
 
 If you're asking if you can plug a dumb usb cable between two 
computers,
 the 
 answer is no. You can only have one host on the bus at one time. To get 
 ethernet via usb between the hosts you will need two usb to ethernet 
nics 
 and a crossover cable, or a cdce device such as the one made by 
prolific. 
thanks, for the clear answer.

 cdce is plugged straight into the usb ports of both machines, but they
 both 
 see it as a network device (ie, it appears as a device to both hosts). 
If 
 you find one let me know, I've been interested in getting one for a 
while.
 
i did not get a pl-2501, but a pl-2302, which is only usb 1.1 compatible

It is a rather old device, but here are the details:
Name: USL-116 USB Net Link Cable
Vendor: NoName
Chipset: Prolific pl-2302
USB: 1.1
OBSD Ethernet Device: upl0 Point-to-Point device

I think it will work as a sync device for pfsync.

Hi list,

I am trying to setup a network between two OpenBSD 3.8 hosts via a USB
interface. I wanted to use the Interface as a pfsync device.
I thought it have read somewhere it is possible but cannot remember where,
so when I issue a: apropos usb | grep -i ether
I feel I will need a USB Ethernet interface, just coupling two hosts via a
USB cable doesn't work. The most promising manual page revealed that way
is the cdce(4), but there is a Prolific and Zaurus mentioned and I belive
this is only working with these devices.

So do I need special USB Ethernet hardware to configure a network between
two OpenBSD hosts connected together via USB, if not, which manpage did I
