Well it means that the call in pbuf.c to updatePacketCount() had either the
src or dst host null (or both, I guess), but that's a symptom of a 'bad
thing'.
void updatePacketCount(HostTraffic *srcHost, HostAddr *srcAddr,
HostTraffic *dstHost, HostAddr *dstAddr,
TrafficCounter length, Counter numPkts,
int actualDeviceId) {
static u_short lastHourId=0;
u_short hourId;
struct tm t, *thisTime;
if((srcHost == NULL) || (dstHost == NULL)) {
traceEvent(CONST_TRACE_ERROR, "NULL host detected");
return;
}
Probably the most helpful starting point would be to run under gdb and put a
breakpoint on the traceEvent() itself.
Then, when it stops, do the bt full stuff (documented at the bottom of
docs/FAQ in the gdb ultra-mini guide).
That will at least tell us WHERE that message is coming out of.
(We should also take this to ntop-dev, because it's gonna get even more
technical)
