Hi In an attempt to catch slow zone transfers, I'd like to see some statistics for each TCP session running a xfer.
As I'm running linux I had a look in /proc/net/tcp and if I read things right, the kernel is actually collecting the number of retransmissions for each session. netstat will not suffice, as it only shows retransmissions globally, not per session. Looking at linux tcp.h there is a struct tcp_info that seems to hold a lot of info, retransmissions included. I have no idea how other platforms do this if at all. Now some might say "Use packet capture", but that will be hard as I'm running IPsec transport mode. The best alternative, from my perspective would be if bind could log a little more info after a xfer is done, like retransmissions, pmtu, rtt, mss. Perhaps not by default, but in debug or something. I hope you get my point. Any suggestion or idea is appreciated. /Tias _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
