owping testing error #73

Closed MayPyoneHann closed 2 years ago

MayPyoneHann commented 2 years ago

Hello,

I have already solved with NTP problem. But I have still a problem with using owping. The error is like this: owping 2001::20 owping: Unable to open control connection to 2001::20.

I also enable the firewall for UDP port 861 for both sides. But in Wireshark, it only shows the two-way TCP protocol on port 861, not UDP. Actually, I cannot ping at all. Is there still needed something to do on the server side or client-side.

That sounds more like you have a network problem rather than one with owamp. You might check that the address you're using is actually valid; 2001:0000/32 is a reserved block for Teredo under RFC 4380.
