Hi, I configured my NTP server in samba 4 according to the article " https://wiki.samba.org/index.php/Time_Synchronisation" however I verified that the NTP server does not respond to requests from Windows NTPv3 clients, it only responds to NTPv4. Following my ntp.conf: # /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help driftfile /var/lib/ntp/ntp.drift # Enable this if you want statistics to be logged. #statsdir /var/log/ntpstats/ statistics loopstats peerstats clockstats filegen loopstats file loopstats type day enable fil...

...and port 123 -n ## Listen for packets filtering host 172.24.102.10 and port 123 While both tcpdumps are running, execute the following: [foo ~]# ntpdate 172.24.102.10 Now, on the tcpdump of VM foo, you will see outgoing packets: 19:45:26.644630 IP 172.24.102.20.ntp > 172.24.102.10.ntp: NTPv4, Client, length 48 As you can see, packets are exiting the server, but there is no response. And the tcpdump of the ntp server is still empty, it doesn't receive the packets (so, it won't reply). But why? Lets troubleshoot further and run ntpdate in debugging mode: [foo ~...
