That's not necessarily true. There's ICMP Source-Quench and depending on the layers below IP there could be a(nother) way to indicate full buffers. You'd probably have to shrink the socket buffer and inspect the network with tcpdump to figure out whether there's a mechanism or not. I would think though there's usually none. -- Christian
