Network debugging

Ping & traceroute

If you suspect a network problem between the monitoring system and your server, it’s helpful to have a traceroute from your NTP server to the monitoring system. You can traceroute to the monitoring network using 139.178.64.42 and 2604:1380:2:6000::15.

You can ping or traceroute from the monitoring network using HTTP, with:

curl http://trace.ntppool.org/traceroute/8.8.8.8
curl http://trace.ntppool.org/ping/8.8.8.8
