RUTX50 GPS NTP Server

Hi!
I’m working on a RUTX50 with RUTX_R_00.07.06.1. Is it possible to use the internal gps for setting up an ntp server without internet server? I activated GPS synchronization and enabled the ntp server. But that doesn’t work. I can’t see a binding with upd 123 on my ipv4 addresses only a binding on :::123.

Thanks.

Hello,

This is because you have IPv6-mapped IPv4 addesses. Check with:

sysctl net.ipv6.bindv6only

on the RUTX50.

From another (linux) system, you can check that it works:

ntpdate -q IPv4-address-of-the-RUTX50
