Exclamation [7.306] Clock / NTP out of sync
Hi, all our systems' clocks were off by a minute today, including Astaro (our local NTP server).

Running 'ntpdate -q pool.ntp.org' on the console verified the clock was wrong but that the servers were reachable.

Restarting the NTP server in webadmin (at 14:33) reset the clock, but I'm worried that it's drifting so much.

Thanks,
Barry


Code:

Hi Barry

Are you still having this issue?

Hi,
The time is correct (0.013 seconds offset according to ntpdate) at the moment, but other than restarting the NTP service, I haven't done anything to 'fix' it, and suspect it will happen again (the above post wasn't the first time I've had this problem in the 7.x series).

Thanks,
Barry

The issue I am having is that I can see all devices updating their clocks via NTP server from ASG with no issues. I can see the allowed NTP request on the firewall itself via the packet tracer but I am unable to perform windows update as it says the clocks are out of sync

UPDATE: I think there is something wrong with the NTP service. My domain controller was unable to connect to the ntp server and it was part of the NTP allowed networks.

I can see the block on the packet rule

UDP
192.168.2.1 : 123
→
192.43.244.18 : 123
I've disabled the NTP function and everything works fine at the moment. I think there is still an issue with 7.XX series

I'm not seeing this issue anywhere. Which servers do you have listed on the 'Time and Date' tab of 'Mnagement >> System Settings'?

Cheers - Bob

Hi Wingman, I frequently see time sync errors on my WinXP boxes (syncing to Astaro 7.502). I've complained about that several times before here, but there doesn't seem to be a real fix.

It seems to fail about 50% of the time for me, so my computers still stay in pretty good sync and I've given up worrying about it at home.

The problem I mentioned here is with Astaro getting out of sync though.

Barry

I had my internal network (192.168.2.0/24) + my vpn pool
so really getting the block on the pf for 192.168.2.1 is strange. I've disabled though and add the appropriate rules and everything works fine
