The way I understand, you should have `ethX` interfaces for your<br>> slaves to hook on to. Perhaps you could try <a href="mailto:babbittner@aol.com's">babbittner@aol.com's</a> idea of<br>> named pipes and if any of the given parameters (to the user-space one)<br>> couldn't be opened, you automatically hook on to a named pipe to transfer<br>> the data?<br>><br>> This would be very useful to test software targeted to work with large<br>> number of slaves, without actually having to buy that many slaves (or<br>> network cards!)<br>><br>> Shahbaz<br>><br>><br>> On Mon, Nov 26, 2012 at 8:39 AM, Raz Ben Yehuda <<a href="mailto:rbenyehuda@manz.com">rbenyehuda@manz.com</a>>wrote:<br>><br>>> On Mon, 2012-11-26 at 02:35 +0100, <a href="mailto:babbittner@aol.com">babbittner@aol.com</a> wrote:<br>>> > I'm attempting to run multiple virtual slaves on one host.
