Hi all,
Is it normal to see bind listening on UDP port 53 using 2 fd?
udp UNCONN 0 0 192.168.10.100:53 0.0.0.0:*
users:(("named",pid=4205,fd=512))
udp UNCONN 0 0 192.168.10.100:53 0.0.0.0:*
users:(("named",pid=4205,fd=15))
tcp LISTEN 0 10 192.168.10.100:53 0.0.0.0:*
users:(("named",pid=4205,fd=17))
tcp LISTEN 0 128 127.0.0.1:953 0.0.0.0:*
users:(("named",pid=4205,fd=21))
Does this make any sense?
According to "rndc status" command "UDP listeners per interface: 1"
