NTP not syncing

I noticed my clock was off; turns out ntpd isn't able to connect.

I can't find *any* NTP config in FreeNAS, so I don't see that I could have altered it stupidly, and it's been working for years.

Clearly it's NOT able to reach the servers:


[root@fsfs ~]# ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
optimize3.exact .INIT. 16 u - 64 0 0.000 0.000 0.000
mdnworldwide.co .INIT. 16 u - 64 0 0.000 0.000 0.000
ntp1.wiktel.com .INIT. 16 u - 64 0 0.000 0.000 0.000


But there doesn't seem to be any low-level networking disconnect:


[root@fsfs ~]# ping ntp1.wiktel.com
PING ntp1.wiktel.com (69.89.207.99): 56 data bytes
64 bytes from 69.89.207.99: icmp_seq=0 ttl=57 time=10.321 ms
64 bytes from 69.89.207.99: icmp_seq=1 ttl=57 time=10.308 ms
64 bytes from 69.89.207.99: icmp_seq=2 ttl=57 time=10.334 ms


If I stop ntpd, ntpdate still can't reach that server I pinged

[root@fsfs ~]# service ntpd stop
Stopping ntpd.
Waiting for PIDS: 93359, 93359.
[root@fsfs ~]# ntpdate ntp1.wiktel.com
16 Mar 19:04:18 ntpdate[94664]: no server suitable for synchronization found
[root@fsfs ~]#


(If I don't stop ntpd I get an error that the NTP port is still in use).

ssh-ing to that server also works -- that is, I get the message about the server key not being known. I don't have an account there, so I can't log in, but that shows ssh is able to make a tcp connection there. I did the ping and ssh tests from the shell window in the FreeNAS web GUI, so it should be going through exactly the same networking infrastructure as ntpd itself is.

Any thoughts? (Oh, restarting ntpd and rebooting the system haven't helped, either; the system reboot was for something else, but it didn't help this.)

This is also FreeNAS 9.10, which is now not current (but no way in hell am I upgrading two weeks before Minicon, with two big projects hoping desperately to be ready by then).

Here's what's in /etc/ntp.conf:

[root@fsfs ~]# cat /etc/ntp.conf
server 0.freebsd.pool.ntp.org iburst maxpoll 10 minpoll 6
server 1.freebsd.pool.ntp.org iburst maxpoll 10 minpoll 6
server 2.freebsd.pool.ntp.org iburst maxpoll 10 minpoll 6
restrict default limited kod nomodify notrap nopeer noquery
restrict -6 default limited kod nomodify notrap nopeer noquery
restrict 127.0.0.1
restrict -6 ::1
restrict 127.127.1.0


I don't remember ever changing it by hand, and the file date matches the latest reboot, so it's whatever was in the config database.

Your NTP config is identical to mine.

It seems that UDP port 123 is being blocked by a firewall. Can you confirm that your router/firewall or even ISP are not blocking UDP 123?

Running these commands from an ssh session to my FreeNAS box. ntpdate with the -q option reports what it would do -- which it can only figure out by actually interacting with the remote servers, right? It just stops short of actually setting the time? It's reporting actual communication with specific servers, I really hope it's not making that up.


[ddb@fsfs ~]$ sudo ntpdate -q 1.freebsd.pool.ntp.org

This is an unexpected result, at least to me. But I do think it disposes of the "port blocked" theory.

Hmmm; okay, with the -d option I should get more detail on what happens, and I might as well let it reset my clock, it won't make things worse.

And that date/time was about 6 minutes off at the time I saw it here. (Compared to what? Yeah, fair question. Compared to my windows box synced to whatever it defaults to, to my "atomic" watch (radio-synced from WWV last night), to my bedside "atomic" alarm clock, to my android smartphone, and to multiple other servers not located here that I don't control, but that will display time; all those agree to very small differences, just my one fileserver is out of step. So I think it's pretty clear which one is wrong.)

oh, and thanks very much for the config comparison; there's enough there I don't understand that I wasn't really sure mine is right, but if that's the default freenas config I can at least figure I didn't break it.

And yes, just falling back to the simplest case still fails the same as yesterday.

Interesting - I've just noticed that I have one FreeNAS server that's "dead on" time, the other is 20 minutes behind ...

Edit - no, I thought I had refreshed the GUI, but apparently not

Having updated yesterday to FreeNAS 11 -- I still have the same NTP problems. I'm now 8 minutes off, and it's getting more and more annoying.

I can reach the servers by ping and ssh (I don't have credentials to log in, but I get to server key exchange, which means that a TCP/IP connection was made and used), but ntpdate doesn't find suitable servers. Can't be as sure what ntpd actually finds, but it never gets out of initialization (refid remains .INIT.).

Running ntpd directly (system copy still shut down) sits as long as I'm willing to wait (more than 10 minutes so far) with nothing beyond this immediate output:

It's been a while since you've commented on this, obviously - though I was curious if you did ever find the solution to this issue? I appear to be having the same issue myself.

Thanks!

I also had the same issue. After a lot of searching and trying, I solved it by running command ntpdate -u <timeserver> as a cronjob. I suspect it is somehow related to my network setup.

Thanks for the solution, I'll do the same! I'm not a FreeNAS expert by any means, very much so a novice. Though from an IP stand point it would be very interesting to figure it out. As you mentioned I'm starting to believe it has something to do with my network topology. Obviously the ISP doesn't appear to be blocking NTP specifically, and I do have other devices that make connections to NTP servers.

I'm using DDWRT on my router - I suppose I could wireshark it at different locations to try and observe what's happening to the UDP traffic, if any, from the FreeNAS device. Though like you said, you can more or less manually run the process to some degree... which only makes me wonder if there is a type of policy or sorts that perhaps either something in my LAN or ISP doesn't like when it requests NTP.

Yeah, and please report if you figure it out! It's not my top priority right now, but if I get around to dig deeper and figure out, I'm going to report too!

I messed around with several things for a while the other night and, honestly? I think it's ATT blocking connections on UDP 123. I was having a hard time understanding why ntpdate -u worked, but also like -d it uses a random port... I'm more of an IP guy by trade, after watching connections and comparing all connections being made, or attempted to be made through my router on UDP 123 never fully resolved.

I also was having issues really proving this just by thought because - my PC's sync to internet time just fine as does my router. Though - I suppose either A. it's using a port other than UDP 123 similar to -d and -u or... it's something about the way it sending it's request to synchronize vs. how a PC or the router may be handling ntp client sync requests. Either way... for me? I suspect if there was a way to force ntp.conf to sync to the servers via a specific port other than UDP 123... they may be the resolve, for me at least.

Or route it through a proxy/vpn perhaps, if possible. (wasn't seeing the option to allow me to edit the previous post - sorry for trailer post)

One last follow up - pretty well confirmed that to some extent that is what must be going on... I sent my traffic over a VPN on my router and then restarted ntpd and now I'm good:

Good to hear you figured it out!
In my case, I don't think my ISP is the culprit, because - oddly enough - a FreeNAS VirtualBox I set up for experimenting also won't sync with the NTP server when its virtual network adapter is set to bridged but it will sync when it's set to NAT.
Go figure out why!
So my FreeNAS box still syncs time by means of that ntpdate -u cronjob.

Hmm... Yes that is interesting. I've worked for ISP's - CLECs/ILECs/Transport & Back haul. I know people usually suggest calling their ISP to see if there would be anything they could do to lift the policies off say, udp 123... but I decided it wasn't worth the time as a typical residential customer receives some pretty low level support and would take quite a bit of effort I'd imagine to reach anyone that COULD help - and also make sure it stays fixed as many ISPs use automated systems so - any change on an account generally queues the system to look at predefined policies and make sure they're all set etc. so the likelyhood of defaulting back I imagine is inevitable.

So, I use policy based routing on my DDWRT Flashed Router to send only certain IP's traffic over a VPN. I didn't want all of my base NAS servers traffic to be looking at the VPN JUST so I can get NTP to work so I decided to create an alias IP via IPv4 and then set the NTP config to listen on that IP only. I guess as I've seen people say previously that - it's sort of "hacky" but... unless you really want to go through all the trouble to fix it with an ISP and hope it stays fixed - it seemed like the best option for me in the long run.

So I just noticed that the clock on my FreeNAS box is wildly off. I don't know how long it's been, but I suspect it is related to when I upgraded to 11.2-U6 from 11.1-U7.

On my FreeNAS box:
Code:
root@saturn:~ # date
Tue Oct 15 04:21:16 AEDT 2019

While on a Debian VM hosted on my FreeNAS box:
Code:
nick@calypso:~$ date
Tuesday 15 October  17:11:50 AEDT 2019

The Debian VM is precisely correct, and the FreeNAS time is not even slightly close. It's obviously not a time zone issue (the time zone is correctly showing on both, and we can see that the minutes are wrong on the FreeNAS box, as well as the hours).

I can ping listed ntp servers from the FreeNAS box, and ntpq both confirms the massive error and suggests that connectivity to the ntp servers is not an issue:

Code:

As far as I can tell, the FreeNAS ntp config is correct (working NTP servers are listed in System / NTP Servers - I can't see an "on/off" switch).

So I am stumped. Why isn't it working? I've never had an issue before. As I say, my suspicion is that FreeNAS 11.2 was the change agent.

So I just noticed that the clock on my FreeNAS box is wildly off. I don't know how long it's been, but I suspect it is related to when I upgraded to 11.2-U6 from 11.1-U7.

On my FreeNAS box:
Code:
root@saturn:~ # date
Tue Oct 15 04:21:16 AEDT 2019

While on a Debian VM hosted on my FreeNAS box:
Code:
nick@calypso:~$ date
Tuesday 15 October  17:11:50 AEDT 2019

The Debian VM is precisely correct, and the FreeNAS time is not even slightly close. It's obviously not a time zone issue (the time zone is correctly showing on both, and we can see that the minutes are wrong on the FreeNAS box, as well as the hours).

I can ping listed ntp servers from the FreeNAS box, and ntpq both confirms the massive error and suggests that connectivity to the ntp servers is not an issue:

Code:
root@saturn:~ # ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter

I know it doesn't answer the question but - and I'm a novice so apologies if I'm pointing out something obvious but - that offset and jitter is where I'm beginning to look and figure out how it's getting so high. Though - I do have to get ready for work and do not have a ton of time right at this very moment to continue my search.

Just off the top of my head - We know with NTP that once a clock gets so far out of uniform that it fails to synchronize properly. I do not know if this would show as a flat out failure to sync - or possible something similar to what you're seeing (obviously I'm no expert in NTP as well!)

I'd be curious if you issued a command to manually resync your NTP clock and keep an eye on it and see if the offset / jitter continue to increment - as when it's working properly they should be fairly low. Have you tried this already by any chance? There are some cases that are suggesting the RTC battery may be going bad. Although I've never witnessed this myself and am unsure what affects a dead RTC battery can have in modern days but - I've heard that can cause strange issues as well. Though - would it affect the VM machine as well? Or - perhaps the virtualization somehow circumnavigates the RTC Battery function where as otherwise it does not?

Again, I see you're an experienced user so try not to flame me too hard if I'm stating the obvious or too basic ;p

Thanks @blucube - we're probably in a similar boat - I'm trying to figure this out as I go along.

So I just did a manual resync:
Code:
# service ntpd stop
# ntpdate pool.ntp.org
16 Oct 22:00:21 ntpdate[35070]: step time server 129.250.35.250 offset 51611.766967 sec
# service ntpd start

This successfully corrected the time. Waited a few minutes then:
Code:
# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 119.18.34.130 ( .GPS.            1 u   23   64    7   43.911  11425.7 6230.87
 x.ns.gin.ntt.ne 249.224.99.213   2 u   27   64   17   29.027  11206.6 9527.77
 pve03.as24220.n 203.14.0.251     3 u   63   64    3   17.221  9226.96 7885.46
 chronos.ntp.tel 58.163.113.212   2 u   23   64   17   17.714  11425.8 9668.58
 chronos1.ntp.te 58.163.113.212   2 u   19   64   17   29.229  11645.3 9865.58

Which is to say it looks like it is already losing time. Quickly. The delays and offsets seem to be all over the place. And sure enough the time is falling behind.

My motherboard reports the battery voltage at 2.97V, which it claims is OK.

So I'm stumped.

What's bizarre is that immediately after a resync, the delays / offsets of just one of the entries is zero, while the rest are large:
Code:
# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
eth1733.vic.ads .NMEA.           1 u    -   64    1   31.510  1075.16   0.000
45.76.113.31 (d 17.253.66.125    2 u    -   64    1   28.967  1073.95   0.000
ntp2.ds.network .INIT.          16 u    -   64    0    0.000    0.000   0.000
chronos.ntp.tel 58.163.115.18    2 u    1   64    1   17.390  1019.30   0.000

Then, shortly after, all the delays / offsets look bad:
Code:
# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================

Any help would be very welcome...
