NTP - chronyd - unable to read socket on port 123 (worked when used ntpd)

970 views Asked by At

I'm trying to read the NTP status on red hat linux server, but I'm getting socket timeout receive error java.net.SocketTimeoutException: Receive timed out

This code works when run against a system using ntpd but not for chronyd?

I expect it's a configuration issue? I've run chronyc tracker and all looks good.

Any ideas as to why this isn't working?

Chrony is a NTP v4 server, which is backwards compatible with a NTP v3 client at best. The code we are using to query the server follows the NTP v2 protocol, which is why it does not work.
