Hi Mark's Recipe might work, but IMHO you have to use a different subnet for each BBB. eg: BBB1 192.168.101.2 and USB1 on the PC 192.168.101.1 BBB2 192.168.102.2 and USB2 on the PC 192.168.102.1 BBB3 192.168.103.2 and USB3 on the PC 192.168.103.1 etc... And the you have add to route rules between all these subnets.....
But - Ethernet might be much easier. If you assign each BBB a fixed IP on eth0, then you can combine almost unlimited BBB's like in a server farm. The only con is that you need two cables for every BBB, 5V and eth. On Thu, Nov 7, 2013 at 4:56 PM, Mark A. Yoder <[email protected]> wrote: > Brian: > I think I've found an answer.
