It's a bit fiddly to arrange, but can you repeat the test and artificially lower the TTL for these packets which disappear? An iptable mangle rule would do the trick -- mangle the TTL only on packets which match this point in the trace. The idea is to reduce the TTL like traceroute does, so you can see which hop is causing these packets to disappear -- perhaps it'll stand out proudly as a QoS device which can be named, blamed and shamed. -- Jamie - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
