Busybox-ntpd server only listening to ipv6

Installing and Using OpenWrt Network and Wireless Configuration
1

Hey all,

I am trying to use busybox-ntpd as NTP server so I have set system.ntp.enable_server to 1 in my /etc/config/system.
After restarting sysntpd, netstat shows that port 123 is only listening on IPv6 and not on IPv4.
The problem is that I have no IPv6 address in my network.

Is there something I am missing?

If you mean that:

root@magiatiko / > netstat -lnp | grep 123
udp        0      0 :::123                  :::*                                13965/ntpd

It's not a problem and it is listening to ipv4 too.

Oh okay, verifying with nmap it is effectively opened thank you
What is the difference between this and processes that listen on both 0.0.0.0 and ::: and those which only listen on :::? (dropbear for example)
