Hi !

In "FreeBSD Security How-To" I read and do:
 
sysctl -w net.inet.tcp.log_in_vain=1
sysctl -w net.inet.udp.log_in_vain=1
 
And now I regulary receive in logs:
 
Oct 21 13:10:20 proxy /kernel: Connection attempt to UDP 194.190.88.1:1171
from 194.190.88.1:53
Oct 21 13:10:20 proxy /kernel: Connection attempt to UDP 194.190.88.1:1172
from 194.190.88.10:53

Oct 21 13:11:37 proxy /kernel: Connection attempt to UDP 194.190.88.1:1179
from 194.190.88.10:53
 
 194.190.88.1 - is my FreeBSD, secondary DNS
 194.190.88.10 - is my Primary DNS
 
 What does it means ?
 Can anybody advise anything ?
 
 Thanks
 Andrey
