I have a FreeBSD Bhyve guest that has in its /etc/rc.conf file the
following:
. . .
cloned_interfaces="lo1 lo2"
ipv4_addrs_lo1="127.0.31.1/32"
ipv4_addrs_lo2="127.0.32.1/32"
. . .
On the same host I have /etc/ntp.conf configured to listen on specific
addresses:
interface ignore wildcard
interface listen 127.0.0.1
interface listen 192.168.216.18
But following a reboot I discovered this using netstat:
udp4 0 0 127.0.0.1.123 *.*
udp4 0 0 127.0.31.1.123 *.*
udp4 0 0 127.0.32.1.123 *.*
udp4 0 0 192.168.216.18.123 *.*
udp4 0 0 216.185.71.18.123 *.*
Why is ntpd listening on the cloned loopback interfaces?
