I too. I said in the first email: "our LTSP (with LTSP Version 4.1.1) clients have two ethernet cards each." ... "For High-Availability reasons, we want to use bonding with this clients now." ... "Who has experience with LTSP and bonding on client side and can give us some hints?" I said in my second email: "No, i need bonding on the (thin) client side for redundancy reasons." What i said third email, you can see below. And again: Your CLIENTS have two NICs each.
