I'm going with the dual-stack address familiy independent solution (/proc/sys/net/ipv6/bindv6only is set to 0). > I've written a small piece of code which tests how the server behaves under heavy load. It basically creates a specified number of threads and hammers the query port of the server with logged real-world queries. This works fine over ipv4. But if I switch to ipv6 (meaning, instead of the ipv4 address of eth0, I give the ipv6 one to getaddrinfo()), strange connection reset/timeout problems arise. This is especially strange because it's all AF-independent, so the very same piece of code runs fine for ipv4, but fails for ipv6. Hello Agoston Could you please repost your mail on netdev@...r.kernel.org, because this address is more appropriate to get in touch with networking guys :) Thank you - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
