Hello,

I have BIND 9.9.4 installed on a server, and have included in the global options:

        rate-limit { responses-per-second 5;
                          log-only yes;
        };

However, if I run from a client:

for n in `seq 1 10`; do dig +short jhorne.csd.plymouth.ac.uk a @141.163.66.138; done

I get 10 correct responses. The query log file on the server shows that 10 queries were received:

17-Jan-2014 13:20:43.662 client 141.163.66.139#55184 (jhorne.csd.plymouth.ac.uk): view plymouth-only: query: jhorne.csd.plymouth.ac.uk IN A + (141.163.66.138)

(The other 9 log entries are the same, except for the milliseconds increasing slightly.)

It's Friday afternoon, so I'm probably missing something obvious :-) I cannot see why all the queries were responded to, I expected some queries to timeout and something to be logged (none of the other bind logs contain anything about rate limiting).



Thanks,

John.
