Nsd and xfer testing

NSD
1

Hi,

I am new bee to NSD.

I am doing performance testing of NSD for ixfers. The NSD is throwing
following error message in log:

[1221002555] nsd[31272]: error: xfrd: zone us received bad query id from
10.91.131.15, dropped

This happens under high xfers transfers notifications from master
(master = 10.91.131.15). The master is a bind server (9.3.x) and slave
is NSD 3.1.1

Is any one know what this error message mean? I am not seeing any side
affects with xfer zone data though.

Thanks,
Srini

haven't seen it. not (much) of a coder, but let's look at the relevant code.

        /* only check ID in first response message. Could also check that
         * AA bit and QR bit are set, but not needed.
         */
        DEBUG(DEBUG_XFRD,2, (LOG_INFO,
                "got query with ID %d and %d needed", ID(packet),
zone->query_id));
        if(ID(packet) != zone->query_id) {
                log_msg(LOG_ERR, "xfrd: zone %s received bad query id
from %s, dropped",
                        zone->apex_str, zone->master->ip_address_spec);
                return xfrd_packet_bad;
        }

I'd start by rebuilding NSD with debug and see what you're getting
versus what NSD expects (-:
