[etherlab-users] Open source virtual Linux Ethercat Slave

[Shahbaz Youssefi]

Hi Raz,

Is it possible with your software to fake networks with large number of
slaves? The way I understand, you should have `ethX` interfaces for your
slaves to hook on to. Perhaps you could try babbittner at aol.com's idea of
named pipes and if any of the given parameters (to the user-space one)
couldn't be opened, you automatically hook on to a named pipe to transfer
the data?

This would be very useful to test software targeted to work with large
number of slaves, without actually having to buy that many slaves (or
network cards!)
